The Astro A20 Wireless are an above-average gaming headset with a good sound and build quality. They're easy-to-use and have a great battery life with a lot of power saving features. They're also decently comfortable but can be a bit tight on the head. Unfortunately, like most gaming headsets, they're a bit limited by their design and transmitter base. You won't be able to use them outdoors or with a different console but on the upside, they are compatible with most PCs, they have an efficient control scheme and a good, customizable sound. Note that we tested the Xbox One variant of this headset, but we expect similar results for the PS4 variant.

6.1

Design

Score components:

The Astro A20 a decent-looking and well-built headphones but they will not be versatile or portable enough for more casual uses. They are limited by the range of their USB transmitter base so you won't be able to use them outdoors and, like most gaming headphones, they are not made for running or sports. On the upside, they have a decently comfortable design and a good build quality despite being a bit tight on the head and mostly made out of plastic. They have large ear cups that are well padded, and an efficient control scheme for gaming that's easy-to-use and well thought-out. They also look a bit more premium than other wireless gaming headsets within their price range like the Turtle Beach Stealth 700.

Style

The Astro A20 look somewhat similar to the Astro A10 but with a different headband design. They feel like premium headphones, especially compared to other headsets in their price range. Also, despite being mostly made out of plastic they feel strudy and durable. They have square-ish ear cups that are well padded and coated with a microfiber fabric that further adds to their high-end aesthetic. Unfortunately, they have a non-detachable mic, and they're limited by their USB base so you won't be able to use them outdoors.

7.0 Comfort
What it is: Adjustability and degrees of freedom, pressure, stiffness and weight.
When it matters: When the headphones are going to be used for long durations.
Score components: Subjectively assigned
Weight : 0.8 lbs
Clamping Force
What it is: The force that the headphones exert on your head, once you have them on. This is purely a measurement of the force applied, which does not take into account the earpad's surface area and the resulting pressure you will feel, on or around your ears.
When it matters: The tighter the headphones, the more force they put on your head. This can get uncomfortable or cause pain and soreness during long listening sessions.
:
1.2 lbs

The A20, like the A10, are decently comfortable headphones but the ear cups do not swivel which makes them a bit tight on the head. The fit may loosen over time, after repeated use, but out-of-the-box they are a bit fatiguing during long gaming sessions. On the upside, they're well padded and covered in a microfiber coating that feels nice on the skin. They won't be the ideal headphones for all gamers due to their tight fit, but they should be comfortable enough for most.

6.8 Controls
What it is: The control scheme of the headphones, the number of functions provided, button layout and ergonomics as well as the quality of tactile feedback.
When it matters: If you want to control volume, pause your music or make phone calls without directly interacting with your audio device.
Ease of use : Good
Feedback : Good
Call/Music Control : No
Volume Control : Yes
Microphone Control : Yes
Channel Mixing
What it is: Being able to mix audio channels directly on the headphones.
When it matters: This is most useful when using a separate chat software so that you can mix in-game audio and chat audio depending on your needs.
:
Yes
Noise Canceling Control : N/A
Talk-Through
What it is: A transparency feature that uses the mics of the headphones to let you hear what is doing on around you without removing them.
When it matters: If you want to be aware of what is going on around you without removing your headphones or while still listening to your audio. This is typically a feature for the noise canceling headphones and passively isolating in-ears that block a lot of noise.
Good value: Yes or adjustable.
:
N/A
Additional Buttons : N/A

The Astro A20 have an efficient control scheme that's easy-to-use and well laid out. You get a great volume dial with good feedback. It doesn't have discrete notches but you do feel it click in place as you adjust which is much better than some of the other gaming headphones we've tested like the Turtle Beach Stealth 700. They have an equalizer button that cycles between 3 presets, (which you can customize through the Astro Command Center) and they also provide channel mixing buttons that are well hidden around the volume dial. Overall, their control scheme looks great, feels intuitive, and delivers good feedback.

6.8 Breathability
What it is: How hot the headphones get when you wear them for an extended period of time.
When it matters: If you often have long listening sessions or use your headphones while doing physical activities like running or working out.
Score components:
Avg.Temp.Difference : 4.6 C

These headphones are decently breathable thanks to their slightly porous pads. However, since they fully encapsulate the ear, they will make your ears a bit warm during long gaming sessions.

1.2 Portability
What it is: The volume of space occupied by the headphones when folded into their most compact format.
When it matters: If you're often on the move and need to carry your headphones in a bag, purse , or pocket.
Score components:
L : 6 "
W : 6.9 "
H : 2.8 "
Volume : 116 Cu. Inches
Transmitter required : Yes

The Astro A20 are slightly smaller than the A10s thanks to their new headband design. However, they are limited in portability since they can only connect wirelessly with their transmitter dongle. Also, like most gaming headphones, they're big, bulky and do not fold into a more compact format. They're a hassle to carry around if you don't have a bag or a backpack and do not come with a case or pouch which is slightly disappointing.

0 Case
What it is: The provided carrying options to protect your headphones when transporting them.
When it matters: To prevent damaging your headphones, if you often carry them in your bag or pocket.
Score components: Subjectively assigned
Type : No case
L : N/A
W : N/A

These headphones do not come with a case.

7.5 Build Quality
What it is: Durability, material quality, cheap/expensive feel.
When it matters: When the headphones are going to be used by multiple users (classes/studios), by children, in tough conditions, on a daily basis, or for exercise.
Score components: Subjectively assigned

The Astro A20, like the A10, are decently well-built. They have a different headband design to the A10's that feels somewhat closer to the A50 but does not look as premium, since the frame is mostly made out of plastic. The ear cups feel dense and sturdy enough to withstand a couple of accidental drops, and the Boom mic is flexible and durable. However, the new headband design feels a bit more susceptible to wear and tear than that of the A10's since there are a lot more moving parts.

7.0 Stability
What it is: How the headphones are designed to prevent them from slipping off your ears or falling off your head.
When it matters: If you plan on using the headphones while doing sports or other physical activities that requires a lot of movement.
Score components: Subjectively assigned

The A20 like the A10 are not made for sports or running. They're tight on the head so they do not move much during casual listening sessions or while gaming. However, like most gaming headsets, they will quickly fall if used while exercising or doing more strenuous activities. On the upside, they're wireless so they won't get yanked off your head because the audio cable got hooked by something.

Sound

What it is: How accurately the audio is reproduced. The tests are performed with the headphones' most commonly used features enabled (noise-cancelling, wireless, etc.)

The Astro A20 is a good sounding closed-back over-ear gaming headset. These headphones have a punchy and powerful bass with very good extension, a well-balanced mid-range, and a good treble. This makes them quite versatile and suitable for most genres, including bass-heavy music as well as video games. However, their bass is prone to a bit of inconsistencies on certain users, their mid-range is a little recessed on vocals and lead instruments, and their treble is noticeably bright, especially on S and T sounds. Additionally, they have great imaging and produce low distortion, but their soundstage is about average. It should be noted that these headphones were tested with the factory tuning EQ preset 1.

8.7 Bass
What it is: Frequency Response from 20Hz-250Hz
When it matters: When the material is heavy on bass frequencies, such as those of kick drums and bass guitar.
Score components:
Std. Err.
What it is: The amount of deviation (weighted standard error) in bass frequency response (20Hz-250Hz) as compared to a target response that would sound perfectly balanced to most people.
When it matters: When a balanced and neutral (reference) bass performance is desired.
Good value: <4dB
Noticeable difference: 0.1dB
:
1.89 dB
Low-Frequency Extension
What it is: The lowest frequency at which the frequency response reaches -3dB of the target response.
When it matters: Shows how extended the bass is.
Good value: <40Hz
Noticeable difference: 5Hz
:
25.2 Hz
Low-Bass
What it is: The average amount of over/under-emphasis in frequency response from 20Hz-60Hz.
When it matters: Kick drums and low frequency effects get their 'thump' from this range. Mostly felt than heard.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-0.97 dB
Mid-Bass
What it is: The average amount of over/under-emphasis in frequency response from 60Hz-120Hz.
When it matters: Melodic bass instruments have most of their fundamental frequencies in this range. This is where the 'body' and 'punch' of the bass sits.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
2.49 dB
High-Bass
What it is: The average amount of over/under-emphasis in frequency response from 120Hz-250Hz.
When it matters: Most instruments get their warmth and full-ness from this range. When over-emphasized, mixes tend to get muddy and boomy.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
1.74 dB

The bass of the A20 is great. The LFE (low-frequency extension) is at 25Hz, which is very good. Accordingly, low-bass is within 1dB of our neutral target. This means for the most of the sub-bass range, the Astro produces just the right amount of thump and rumble, which is common to bass-heavy music genres and video game effects. Mid-bass, responsible for the body of the bass guitars and punch of the kick drums is overemphasized by 2.5dB, bringing excess emphasis to this region, but some users may find it pleasing. However, the 2dB overemphasis in high-bass adds a bit of boominess to the sound.

8.1 Mid
What it is: Frequency Response from 250Hz-2KHz
When it matters: When the material is heavy on mid-range frequencies. This is the case for the majority of audio content.
Score components:
Std. Err.
What it is: The amount of deviation (weighted standard error) in mid frequency response (250Hz-2.5KHz) as compared to a target response that would sound perfectly balanced to most people.
When it matters: When a balanced and neutral (reference) mid performance is desired.
Good value: <4dB
Noticeable difference: 0.1dB
:
2.57 dB
Low-Mid
What it is: The average amount of over/under-emphasis in frequency response from 250Hz-500Hz.
When it matters: Most instruments have their fundamentals or low harmonics in this range. Over-emphasis in this range sounds muddy and cluttered. Under-emphasis, thins out the vocals and lead instruments.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-1.47 dB
Mid-Mid
What it is: The average amount of over/under-emphasis in frequency response from 500Hz-1KHz.
When it matters: This range is occupied mostly by upper harmonics. Over-emphasis sounds forward and boxy. Under-emphasis pushes instruments to the back of the mix.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-1.25 dB
High-Mid
What it is: The average amount of over/under-emphasis in frequency response from 1KHz-2KHz.
When it matters: Most instruments, especially vocals, get their intensity and clarity from this range. Over-emphasis sounds honky and harsh, under-emphasis sounds weak and distant.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-3.49 dB

The mid-range is very good. The response is relatively even and flat, but for most of the range, it is a bit recessed and under our neutral target. Low-mid and mid-mid are lacking by about 1.5dB and high-mid is underemphasized by about 3.5dB. This nudges vocals and lead instruments towards the back of the mix by thinning them out and giving more emphasis to the bass and treble ranges.

7.7 Treble
What it is: Frequency Response from 2KHz-20KHz
When it matters: When the material is heavy on high-range frequencies, such as voice, cymbals, and any other material where brightness, brilliance and airiness is desired.
Score components:
Std. Err.
What it is: The amount of deviation (weighted standard error) in treble frequency response (2.5KHz-20KHz) as compared to a target response that would sound perfectly balanced to most people.
When it matters: When a balanced and neutral (reference) treble performance is desired.
Good value: <4dB
Noticeable difference: 0.1dB
:
3.77 dB
Low-Treble
What it is: The average amount of over/under-emphasis in frequency response from 2KHz-5KHz.
When it matters: Almost all instruments rely on this range for their presence, detail, and articulation. Over-emphasis can sound harsh and painful. Under-emphasis hurts the comprehensibility of vocals and lead instruments.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-0.65 dB
Mid-Treble
What it is: The average amount of over/under emphasis in frequency response from 5KHz-10KHz.
When it matters: This is the sibilance range. Cymbals, vocals, and lead instruments rely on this range for brightness and presence. Over-emphasis sounds piercing and painful, under-emphasis sounds dull and lispy.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
5.46 dB
High-Treble
What it is: The average amount of over/under-emphasis in frequency response from 10KHz-20KHz.
When it matters: This range gives brilliance and airiness to the sound. Over-emphasis sounds hissy, under-emphasis sounds closed-up and lifeless.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-1.12 dB

The Astro A20 has a good treble range performance. The overall response is relatively even, but shows a 15dB tilt towards 10Khz and is mostly overemphasized throughout the range. This brings a bit of extra brightness and emphasis to vocals, lead instruments and cymbals. It also means that these headphones could be a bit sibilant, that is, sharp and piercing on S and T sounds.

Raw Frequency Response
What it is: The average uncompensated frequency response of the headphone. For in-ears and earbuds, this corresponds to the average of 5 measurements/re-seats on the dummy head (HMS). For over/on-ear headphones, this corresponds to the average of 5 measurements/re-seats on the HMS (Head Measurement System) for the mid and treble ranges, and 5 measurements/re-seats on 5 human subjects for the bass range.
When it matters: This is for those who want to see the raw and uncompensated frequency response of the headphone. Some of the more advanced users, are able to read and evaluate headphone frequency response in its raw form and without compensation. This will be especially useful to them if they have their own headphone compensation/target curve, which may differ from the compensation curve/target response used by RTINGS.com.
7.2 Frequency Response Consistency
What it is: The amount of deviation of each frequency response pass, from the average frequency response.
When it matters: Shows how consistently the headphones perform after re-positioning them.
Score components:
Avg. Std. Deviation
What it is: The average amount of deviation in frequency response of 5 re-seats, from the average frequency response.
When it matters: Shows how consistently the headphones perform after re-positioning them.
Good value: <0.5
Noticeable difference: 0.1
:
0.57 dB

The frequency response of the A20 is decently consistent. In the bass range, the maximum deviation measured across our five human subjects is about 4dB at 20Hz, which is subtle but noticeable. However, the biggest drop in bass delivery was on the subject who wears glasses, and the response was more consistent on other test subjects. In the treble range, up to 10KHz, the maximum deviation measured across five re-seats was about 9dB, but mostly in a narrow range around 7KHz.

8.2 Imaging
What it is: Imaging qualities are inherent to the audio content, the headphones have to 'reproduce' them rather than 'create' them. They determine how accurately the objects are positioned in the stereo image, and how transparent the imaging is.
When it matters: When accurate positioning of the objects in the stereo image, and clear and transparent imaging is desired.
Weighted Group Delay
What it is: The average amount of group delay calculated based on a perceptual weighting filter. Group delay indicates how long it takes for each frequency to reach their maximum amplitude. This is a monaural quality and can be perceived even with one ear.
When it matters: Headphones with lower group delay have more transparent imaging and a tighter bass. Headphones with higher group delay in the bass range tend to have a wimpy and loose bass, and headphones with higher group delay in the treble range tend to have a less transparent imaging.
Good value: <0.5
Noticeable difference: 0.1
:
0.27
Weighted Amplitude Mismatch
What it is: The Left/Right balance of our test unit, that is, the amount of amplitude difference between the left and right drivers. This is not a design test, but a marker for manufacturing tolerance and ergonomics.
When it matters: When a properly balanced stereo image and low manufacturing tolerance is desired. A poor score indicates a noticeable difference in level between the left and right drivers.
Good value: <1.5
Noticeable difference: 0.1
:
1.11
Weighted Frequency Mismatch
What it is: The amount of difference (Std. Err.) between the frequency response of the left and right drivers of our test unit. This is not a design test, but a marker for manufacturing tolerance and ergonomics.
When it matters: When an even and stable stereo image, as well as a low manufacturing tolerance, is desired. A poor score indicates there may be 'holes' in the stereo image at certain frequencies.
Good value: <2
Noticeable difference: 0.1
:
2.2
Weighted Phase Mismatch
What it is: The amount of difference (Std. Err.) between the phase response of the left and right drivers of our test unit. This is not a design test, but a marker for manufacturing tolerance and ergonomics.
When it matters: When an even and stable stereo image, as well as a low manufacturing tolerance is desired. A poor score indicates there may be inaccuracies in the stereo image reproduction at certain frequencies.
Good value: <16
Noticeable difference: 3
:
4.77

The imaging is great. Weighted group delay is at 0.27, which is within good limits. The GD graph also shows that the group delay response never crosses the audibility threshold, indicating a tight bass and a transparent treble reproduction. Additionally, the L/R drivers of our test bench were well-matched, which is important for the accurate placement and localization of objects (voices, instruments, and video game effects) in the stereo image.

7.1 Soundstage
What it is: Soundstage qualities are not inherent to the audio content, the headphones have to 'create' them rather than 'reproduce' them. They determine whether the sound is perceived to be coming from inside or in front of the head, how open and spacious the soundstage is, how much the headphones acoustically interact with the environment, and how strong the phantom center is.
When it matters: When an accurately produced, large and spacious soundstage, similar to that of a stereo loudspeaker setup is desired.
PRTF Accuracy (Std. Dev.)
What it is: The standard deviation of the PRTF (Pinna-related transfer function) of the headphones compared to a reference loudspeaker's PRTF at 30°. This quality is monaural and can be perceived even with one ear. This test does not apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters: An accurate pinna activation is mainly responsible for how natural and speaker-like the soundstage is perceived to be. The less error in the shape of the PRTF, the more natrual and speaker-like the perception of the soundstage will be. High amounts of error may indicate a soundstage that is unnatural or odd.
Good value: <2.5
Noticeable difference: 0.1
:
2.03 dB
PRTF Size (Avg.)
What it is: The average amplitude of the PRTF (Pinna-related transfer function) of the headphones compared to that of a reference loudspeaker's PRTF at 30°. This quality is monaural and can be perceived even with one ear. This test does not apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters: This value is responsible for the perceived size of the soundstage. The higher the value, the larger the perceived size of the soundstage. However, values above the reference (5.0dB) could result in a soundstage that is perceived as unnatural or odd.
Good value: >3.7
Noticeable difference: 0.1
:
4.67 dB
PRTF Distance
What it is: The depth of the "10KHz notch" of the headphone's PRTF, which is caused by phase cancellations at the concha. This quality is monaural and can be perceived even with one ear. This test does not apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters: This value is mainly responsible for the perceived distance and elevation of the soundstage. A small distance value may result in a soundstage that is perceived to be located inside the head. Larger values may help pull the soundstage out from inside of the head and bring it to the front.
Good value: >13
Noticeable difference: 1
:
13.28 dB
Openness
What it is: How open the headphones are, and how open and spacious they sound. This quality is monaural and can be perceived even with one ear. This test differentiates between acoustically and electronically produced crosstalk and only takes the acoustically generated crosstalk into account. This value is the inverse of the Noise Isolation test score, and could be indirectly related the acoustic impedance of the headphones.
When it matters: When a headphone with a sense of an open, and spacious soundstage is desired. A value of 10 indicates a fully open headphone, and a value of 0 indicates a fully closed headphone.
Good value: >7.5
Noticeable difference: 0.5
:
6.0
Acoustic Space Excitation
What it is: How loud the headphones are, and how much they excite their environment acoustically. If the headphones are loud and open enough, the sound leaking from the headphones will be affected by the environment (reflections/reverb) before reflecting back into the open headphones and to the listener's ears. This quality is monaural and can be perceived even with one ear. This value is the inverse of the Leakage test score.
When it matters: Headphones with higher excitation values, similar to openness, tend to have soundstages that are perceived as more open and spacious.
Good value: >7.5
Noticeable difference: 0.5
:
5.5
Correlated Crosstalk
What it is: How strong and solid the phantom center is. This is mostly a stereo quality and its effects on mono content are minimal. This test is sensitive to the phase of the crosstalk and whether it is produced acoustically or electronically.
When it matters: When a true reproduction of the stereo image is desired. A value of 0 indicates no crosstalk, or that the existing crosstalk is not correlated enough to affect the phantom center. A negative score means the crosstalk is out of phase with the original signal, resulting in a slightly wider stereo image at the expense of creating a 'hole' at the center of the stereo field. A positive score means the crosstalk is in phase and positively affecting the phantom center.
Good value: >1dB
Noticeable difference: 0.3dB
:
0.0 dB

The Astro A20 has a decent soundstage. The PRTF graph shows a good amount of pinna activation with good accuracy. However, there's no 10KHz notch present really. This suggests that the soundstage will be perceived to be relatively large and natural, but located inside the listener's head, as opposed to in-front.

7.5 Total Harmonic Distortion
What it is: The subtle, unwanted frequencies (harmonics) produced alongside the intended frequencies.
When it matters: When clean and pure sound reproduction is desired, though its effect is not as noticable as frequency response.
Score components:
Weighted THD @ 90
What it is: The overall amount of harmonic distortion measured at 90dB SPL. To make the score more perceptually relevant, more weight is given to the higher frequencies.
When it matters: How pure the sound is at moderate listening levels.
Good value: <0.100
Noticeable difference: 0.1
:
1.203
Weighted THD @ 100
What it is: The overall amount of harmonic distortion measured at 100dB SPL. To make the score more perceptually relevant, more weight is given to the higher frequencies.
When it matters: How pure the sound is at loud listening levels.
Good value: <0.300
Noticeable difference: 0.1
:
3.593

The harmonic distortion performance is good. In the bass range, the amount of THD produced is within good limits, even at 100dB SPL. In the mid and treble ranges, however, there are sharp peaks in THD which could make the sound of those frequencies a bit harsh and brittle.

4.4

Isolation

Score components:

The Astro A20, like the A10 and A50, do not have the best isolation against ambient noise. This is most likely due to the slightly porous padding material on the ear cups, which improves breathability but also makes them worse to use in loud, noisy environments, like being at a gaming competition. You can mask some of the chatter and ambient noise of your surroundings by increasing the voice or game volume, but unfortunately, they also leak quite a bit so they may be a bit distracting to the people around you in quieter conditions. 

3.9 Noise Isolation
What it is: How much outside noise is blocked out by putting the headphones on.
When it matters: If the headphones are going to be used in a noisy environment (airplane, subway, etc.)
Score components:
Isolation Audio
What it is: The simulated noise isolation of the headphones, demonstrating how much outside noise is blocked out by putting the headphones on. This recording is created using an EQ and is not an actual recording. For headphones with ANC (active noise cancellation), the playback simulates the isolation with ANC enabled.
When it matters: When the headphones are going to be used in a noisy envinronment (airplane, subway, etc.)

What it is: The overall amount of noise isolation in the treble range (2.5KHz-20KHz).
When it matters: When the environment's noise is treble-heavy. Although uncommon, areas with sharp sounds fall under this category.
Good value: <-30dB
Noticeable difference: 1dB
:
-27.58 dB
Self-Noise
What it is: The amount of noise created by the active electronics of the headphones (if applicable), measured from 300Hz-20KHz. Applies mostly to wireless and noise-cancelling headphones.
When it matters: If too loud, it could become distracting when listening to quiet material like podcasts and audiobooks.
Good value: <16dB
Noticeable difference: 1dB
:
20.14 dB

The Astro A20 has an inadequate isolation performance. In the bass range, occupied by the rumble of bus and airplane engines, they don't achieve any isolation. In the mid-range, important for blocking out speech, they achieved about 4dB of reduction, which is sub-par and barely noticeable. In the treble range, where sharp sounds like S and Ts sit, they isolate by more than 27dB, which is above average.

5.2 Leakage
What it is: The amount of sound bleeding out of the headphones.
When it matters: When the listener doesn't want people around them (in office, recording studio, etc.) to hear what is being listened to.
Score components:
Leakage Audio
What it is: The simulated sound leakage heard 1 foot away from the user, while the user is listening to a 100dB SPL signal. This recording is created using an EQ and is not an actual recording.
When it matters: When you don't want people to hear what you are listening to.

:
No

The Astro A20 have a good boom microphone. In quiet environments, speech recorded or transmitted with this mic will sound relatively warm and full-bodied, but it will lack a bit of detail and brightness. However, it will still be easy to understand and comprehend. In noisy environments, it can separate speech from background noise in most situations, even loud environments like gaming competitions and subway stations.

7.1 Recording Quality
What it is: Microphone recording quality shows how natural, neutral, extended and intelligible speech would be with the device under test, in a quiet environment.
When it matters: A microphone with a good recording quality ensures that the person listening to you would hear a full, clear, and easily understandable speech. Therefore, it is important whenever a good quality of speech transmission and intelligibility is needed.

What it is: Actual audio recording of the headphone's microphone, recorded while placed on the dummy head, with speech being played back through the dummy head's mouth simulator.
When it matters: When a clean, full, and intelligible speech transmission is required.
:
LFE
What it is: Low-frequency extension shows how deep the bass response of the microphone is, and therefore, how deep and full your voice would sound to the listener. It is the lowest frequency at which the frequency response reaches -3dB of the target response.
When it matters: LFE is not a big factor in speech intelligibility and even speech recorded with a mic that has an LFE of 500Hz could still be easily understood. Therefore, it is mostly important if you are concerned with how deep and full your voice would be heard.
Good value: <150Hz
Noticeable difference: 30Hz
:
91.1 Hz
FR Std. Dev.
What it is: Frequency Response Standard Deviation shows how accurately and balanced sound is captured by the microphone at each frequency. FR Std. Dev. is calculated between LFE and HFE, and the rest of the spectrum is ignored.
When it matters: A good frequency response is desired when a natural and neutral speech quality is desired. As opposed to HFE which is more a metric for speech intelligibility, frequency response could be considered as a metric for a natural and neutral sound.
Good value: >3.5dB
Noticeable difference: 0.5dB
:
1.96 dB
HFE
What it is: High-frequency extension is the highest frequency at which the frequency response reaches -3dB of the target response. It shows how extended the treble response of the microphone is.

Good value: >8KHz
Noticeable difference: 1KHz
:
1974.03 Hz
Weighted THD
What it is: The unwanted frequencies (harmonics) produced alongside the intended frequencies, which cause deformation of an output signal compared to its input.
When it matters: When clean and pure sound reproduction is desired, though its effect is not as noticable as frequency response.
Good value: <1.5
Noticeable difference: 1.0
:
0.157
Gain
What it is: Shows how much louder the microphone can go above our reference loudness level. The gain value is reported relative to our reference level, which is 94dB at a distance of 5cm from the mouth.
When it matters: A microphone with a high gain is important when the input signal (speech) is very quiet. For example when whispering, or talking on the phone in a library.
Good value: >18dB
Noticeable difference: 3dB
:
43.26 dB

The recording quality of the microphone is decent. The LFE (low-frequency extension) of 91dB, suggests that speech recorded/transmitted with the mic will sound relatively warm and full-bodied. The HFE (high-frequency extension) is at 2KHz, but since the cut-off is not very sharp until 6KHz, speech may lack a bit of brightness and detail, but it won't sound muffled and it will be easy to understand.

7.9 Noise Handling
What it is: How well the microphone is able to separate speech from background noise, so that the transmission would include more voice and less noise.
When it matters: When a clean and intelligible speech transmission is desired in a noisy situation like talking on the phone on a busy street or on the bus.

Speech + Pink Noise :
Speech + Subway Noise :
SpNR
What it is: Speech to Noise Ratio is the difference in level between speech and background noise as heard by the listener
When it matters: If the microphone is going to be used in a noisy environment, it is important for it to be able to separate the speech from background noise, so the voice would be easily audible and understandable.
Good value: >24dB
Noticeable difference: 3dB
:
27.21 dB

The microphone is very good at noise handling. In our SpNR test, they achieved a speech-to-noise ratio of 27dB, meaning they can easily separate speech from ambient noise in most loud environments, even subway stations and gaming competitions. However, they may struggle a little bit in extremely loud and demanding situations.

Compared to other Headphones

The A20 are a decent gaming headset with a good sound and build quality. They come with a base that's limited to the console variant you purchased and doesn't have as many inputs as Astro A50 or the SteelSeries Arctis 7, but it offers a good wireless range and low enough latency for gaming. They have a decently comfortable design although they can be a bit tight on the head for some users. If you value a good sound quality for your gaming headset and you mostly game on one console or PC, then they're a good choice. However, they won't be as versatile as some of the competing models below. See our recommendations for the best Xbox One headsets, the best PS4 headsets, and the best wireless gaming headsets.

Astro A10

The Astro A20 Wireless are better gaming headphones than the Astro A10. Their wireless design gives you more freedom and more range to play from your couch. You also get channel mixing and a mic mute switch, which are features the A10 is lacking. On the other hand, the A10 will give you a gaming experience without any delay and their microphone is noticeably better than the wireless A20. However, the A20 have better sound quality and have a companion app that lets you EQ the sound to your liking. Unfortunately, you can’t use the headset wired, so you’ll need to keep it charged, which you won’t have to do with the wired A10.

Astro A50 Wireless

The Astro A50 ​are noticeably better gaming headphones than the Astro A20 model. They are better made and are noticeably more comfortable, which is great for long gaming sessions. Their out-of-the-box sound quality is also slightly better and their microphone has a more natural recording quality. Their charging dock also has inputs, which is convenient. On the other hand, the A20 have slightly better battery life and take less time to charge. However, their latency is also higher than the A50.

Turtle Beach Stealth 700 Wireless

The Astro A20 is a better-sounding gaming headset than the Turtle Beach Stealth 700. Their default sound profile is more accurate, and you also have access to an EQ in the Astro Command Center app to customize them to your liking. However, if you need a microphone to play online with friends, the Stealth 700 has the edge in that category. Speech transmitted will be clearer and decently full-bodied. On the other hand, the Astros feel better-built and not as plasticky as the Stealth 700, but you won’t be able to stream music via Bluetooth while gaming, which you can do with the Turtle Beach headset.

LucidSound LS31 Wireless

The LucidSound LS31 is a better gaming headset than the Astro A20. It has lower latency, is more comfortable, and has more control options thanks to the channel mixing dials. It also has a better microphone for online gaming, and its battery life lasts a bit longer than the Astros. On the other hand, the A20 have better sound quality and also have an app to EQ the headphones to your liking. Unfortunately, they can’t be used wired like the LS31 can, and their latency and wireless range are a bit worse.

Conclusion

Score components:
The Astro A20 are above-average gaming headphones but won't be ideal for all use cases. They have a simple, well-built design with well-padded ear cups and a good base that offers an optical input. They're decently comfortable and have a fairly low latency for gaming and watching movies. However, they are limited by their transmitter, so you can't use them with a different console or outdoors and they're not designed for casual use.
7.7 Critical Listening
What it is: The level of audio fidelity a headphone can reproduce. Therefore a balanced and true representation of bass, mids, treble, soundstage and imaging, as well as a comfortable listening experience, is essential for critical listening.
Score components:
Good for critical listening. The Astro A20 Wireless have a good bass and a decently balanced treble reproduction although they can be a bit bright with some tracks. They won't have the most spacious soundstage since their closed-back headphones, but on the upside, they should sound good enough even for more critical listeners.
5.6 Commute/Travel
What it is: How well the headphones handle the loud environments involved in commuting or traveling. Therefore your listening experience should be comfortable, hassle-free and as isolated from noise as possible.
Poor for commuting. The Astro A20 are not made for traveling so they do not block a lot of noise, and they have a bulky design that doesn't fold. They're also limited by their USB transmitter so unless you use them with your laptop, on a long bus trip or flight, then they will not be suitable for travel.
5.6 Sports/Fitness
What it is: How well-adapted the headphones are, to use while doing sports or strenuous exercise. Therefore the headphones should not be too cumbersome and deliver a stable and comfortable listening experience.
Sub-par for sports. The Astro A20 Wireless are not made for running and jogging. They're big and bulky headphones limited by their transmitter base.
6.5 Office
What it is: How well the headphones can deliver a comfortable and isolated listening experience in an office-like environment. They should not leak much and should block the noise of a busy office.
Average for office use. The Astro A20 Wireless don't block a lot of noise, so you will hear what's going on around you. They also leak quite a bit so they may distract your colleagues. On the upside, they're decently comfortable, they're compatible with PCs, and they have a long battery life so you can listen to your music continuously for hours.
Average for home theater use. They have a good sound and a decent wireless range for most home theater set-ups. They also have a low enough latency to be suitable for watching movies and an optical input. Unfortunately, they do not have as many connection options as the A50, and they tend to be a bit tight on the head, which may get slightly uncomfortable during long viewing sessions.
7.3 Gaming
Above-average for gaming. The Astro A20 have low enough latency to be suitable for gaming, a convenient wireless design, and they're decently comfortable. They won't be the best headphones if you have a particularly noisy gaming environment, like being at a competition. However, they deliver on most aspects that make a good gaming headphone. They have a clear and reliable microphone, a good battery life with power saving features, and a well-balanced sound that you can customize through the Astro Command Center. Unfortunately, they are a little tight on the head which may get a bit fatiguing during long gaming marathons.
