The Sony WI-C600N are okay around-the-neck in-ear headphones that have a decent audio reproduction and ANC feature. They are quite versatile for various everyday uses, but their neckband design might not be for everyone. They also have a disappointing 6-hour battery life compared to neckband headphones, and they take about 2 hours to charge. On the upside, they can be used for commuting or at the office since they block out a good amount of ambient noise and they are compatible with the Sony mobile app, which offers plenty of customization and control options.

Design

Score components:
Sony WI-C600N Wireless Design Picture

The Sony WI-C600N are around-the-neck headphones that have a flexible and malleable neckband, similar to the Beats BeatsX. They are fairly lightweight and fit comfortably inside your ears thanks to their small design. They don’t feel as well-built as the Sony WI-1000X, but are more portable since they can fold into a more compact format. Their controls are useful, but it might be a bit hard to push the buttons due to their small size and rubber coating. They’ll be stable for some sports, but can’t be used passively like the WI-1000X.

Style
Sony WI-C600N Wireless Design Picture 2

The Sony WI-C600N are around-the-neck headphones that look fairly similar to the Sony WI-1000X, but with a slightly cheaper feel. They don’t stand out very much and they come in three different color schemes: black, blue, or grey. The neckband is fairly flexible and malleable, but the cables are very thin and look fragile.

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
Sony WI-C600N Wireless Comfort Picture
Weight : 0.07 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.
:
0 lbs

The WI-C600N are fairly comfortable in-ears. They are very lightweight and don’t apply too much pressure inside your ears, but some may still not find the in-ear fit to be comfortable. Also, the neckband is lightweight, but not everyone will like having something around their neck. They come with 4 tip options to help you find the best possible fit, but they aren’t as comfortable as the Bose QuietControl 30.

7.7 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.

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.
:
Yes
Additional Buttons : N/A

The control scheme of the WI-C600N offers common functionalities, but the small size of the buttons and the rubber coating makes it a bit hard to press them. On the left side of the neckband, you get a call/music management button, a volume rocker, and the power button. The play/pause button also acts as a track skipper with multi-presses. On the right side, you have the ANC control button that lets you cycle between ANC on, ambient mode enabled, and ambient mode disabled. You can also map that button inside the app to trigger Google Assistant (not available with other voice assistants).

9.2 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 : 0.8 C

Like most in-ear headphones, these Sony WI-C600N are very breathable as they don’t trap heat under an ear cup and allow a good amount of airflow. You shouldn’t sweat more than usual when wearing these during physical activity and won’t notice a big difference in temperature during casual listening sessions.

7.8 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.

The Sony WI-C600N are fairly portable. Their neckband design takes more space than a typical wireless in-ear design, but it is malleable and flexible. You could fit them in large pockets, or in a bag, and bring them around. Also, their design is easy to carry around your neck at all times, which makes them a bit more portable than over-ear headphones. Unfortunately, they don’t come with a pouch or a case to protect them.

Score components: Subjectively assigned
Sony WI-C600N Wireless Build Quality Picture

The Sony WI-C600N are fairly well-built, but don’t feel as solid as the WI-1000X. The neckband is malleable and won’t snap under physical stress, which is good. However, the cables are very thin and don’t feel very durable. On the upside, they don’t feel as cheaply made as the WI-C400. The buds are also magnetic, which helps with cable management.

7.5 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
Sony WI-C600N Wireless Stability Picture

The Sony WI-C600N are fairly stable inside the ears and don’t move too much thanks to their very small design. They sit nicely, but not everyone will like jogging or doing physical activity with a neckband. The buds feel secure, but a light tug on the cable can make them pop out. On the upside, since they are wireless, you don’t have to worry about any cable being in your way or getting hooked on something, yanking the headphones out.

Cable

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.)
Sony WI-C600N Wireless Frequency Response

The Sony WI-C600N are decent sounding in-ears that sound fairly similar to the WI-1000X. They have a powerful, extended, and consistent bass, a very good and well-balanced mid-range, and good treble as well. However, they might sound a bit boomy, thick, and cluttered, which will mostly affect vocals and lead instruments. Also, their treble is slightly uneven, resulting in sibilants (S and T sounds) being overly sharp and piercing, while some may lack detail and brightness. Overall, these headphones are fairly versatile for a wide variety of music genres but will be better suited for bass-heavy music.

9.0 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:
Sony WI-C600N Wireless Bass

12.42 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
:
-0.37 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
:
1.01 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
:
2.57 dB

The bass performance of the Sony WI-C600N is excellent. Their LFE (low-frequency extension) is down to 12Hz, which is excellent. This and their very accurate low-bass means they’ll be able to reproduce the right amount of thump and rumble common to bass-heavy genres. Unfortunately, there’s a 2.5dB overemphasis in high-bass, which will result in a bass that sounds slightly boomy and muddy.

8.2 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:
Sony WI-C600N Wireless Mid
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
:
2.43 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
:
3.84 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
:
0.4 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
:
0.45 dB

These headphones have very good mid-range performance. The response throughout the range is very close to our target curve, but there is a bump in low-mid, which is the continuation of the high-bass overemphasis. This will result in vocals and lead instruments sounding a bit thick and cluttered.

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:
Sony WI-C600N Wireless Treble
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
:
3.78 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
:
-2.37 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
:
-1.05 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
:
-3.57 dB

The treble performance of the WI-C600N is good. There’s a shallow but broad dip under 6kHz that will negatively affect the brightness and detail of vocals and leads. Also, after the 6kHz region, the response is fairly uneven, meaning that some sibilants (S and T sounds) will lack detail while others might feel overly sharp and piercing on already bright tracks. However, not everyone hears the treble frequencies the same way, so your listening experience may vary.

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.
9.4 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:
Sony WI-C600N Wireless Consistency L Sony WI-C600N Wireless Consistency R
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
:
0.12 dB

They have excellent frequency response consistency. Assuming the user is able to achieve a proper fit and an air-tight seal using the assortment of tips that come with the headphones, they should be able to get consistent bass and treble delivery every time they use the headphones.

9.3 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.
Sony WI-C600N Wireless Group Delay Sony WI-C600N Wireless Phase Response
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: <16
Noticeable difference: 3
:
1.0

The stereo imaging of these headphones is amazing. The weighted group delay is at 0.17, which is very good. The GD graph also shows that the entire group delay response is below the audibility threshold, suggesting a tight bass reproduction and a transparent treble. Additionally, the L/R drivers of our test unit were well-matched in amplitude, frequency, and phase response, which is important for the accurate placement and localization of objects (voices, instruments, video game effects) in the stereo image. However, these results are only valid for our unit, and yours may perform differently.

1.3 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

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.

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

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

3.1
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

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 soundstage of the Sony WI-C600N is poor. Since creating a large and speaker-like soundstage is partially dependent on having a speaker-like pinna activation, and in-ear headphones bypass the pinna (the outer ear) and don't interact with it, their soundstage will be perceived to be small and located inside the listener's head. Their closed-back design also means that their soundstage won't feel and open as open-back earbuds like the AirPods 2 2019 and the SoundSport Free.

7.4 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:
Sony WI-C600N Wireless Distortion
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.

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
:
2.011

The total harmonic distortion performance of these headphones is decent. The THD is within good limits throughout the range, but the graph shows high peaks in the mid and treble ranges around 750Hz and 5.5kHz. This could make these frequencies a bit harsh and impure. On the upside, there is no big jump in THD under heavier loads, which is good.

7.5

Isolation

Score components:

The Sony WI-C600N are active noise cancelling in-ears with good isolation performance. They isolate against a decent amount of lower frequencies like engine rumbles, which is good for commuting. They also don’t leak much, so you’ll be able to raise your listening volume to mask more ambient noise, making them a decent choice for a daily commute and also at the office.

6.8 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 envinronment (airplane, subway, etc.)

The Sony WI-C600N have a decent isolation performance. With their ANC (active noise cancelling) enabled, these in-ears achieved about 12dB of isolation in the bass range, which is decent. This means they will be able to cancel out the low rumbling noises like airplane and bus engines to a good degree. However, there seems to be a weak point around 250Hz. In the mid-range, important for blocking out speech they isolate by 18dB, which is also good. In the treble range, occupied by sharp sounds like S and Ts and air conditioning systems, they achieved 31dB of isolation, which is good. However, it seems the noise isolation gets worse once the ANC is enabled, but this won't be very audible.

The microphone of the Sony WI-C600N is mediocre. In quiet environments, speech recorded or transmitted with this mic will sound relatively thin, noticeably muffled, and lacking in detail. It may also be prone to pops and rumbling noises. In noisy situations, it will struggle to separate speech from ambient noise in moderately loud environments such as a busy street and won’t be the best option for calls.

6.4 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.

Good value: >18dB
Noticeable difference: 3dB
:
41.71 dB

The recording quality of the integrated microphone is okay. LFE (low-frequency extension) is at 65Hz, which is good, but the graph shows that there’s a bump centered around 100Hz, which means the mic will be sensible to pops and rumbling noises. The dip around 150Hz means transmitted/recorded speech with this mic will sound noticeably thin. The HFE (high-frequency extension) of 2.5kHz indicates speech that lacks detail and is noticeably muffled. However, the limited high-frequency extension is a limitation of the Bluetooth protocol and is a problem with all Bluetooth microphones. Speech will still be decently intelligible with this microphone in very quiet environments.

6.2 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.

Compared to other Headphones

Sony WI-C600N Wireless Compare Picture

The Sony WI-C600N are decent around-the-neck headphones that are kind of an in-between of the Sony WI-C400 and the WI-1000X. They have a good isolation performance and a malleable, flexible neckband. However, their battery life is fairly short and their design might not be for everyone. See our recommendation for best neckband headphones, the best earbuds and in-ear headphones, and the best wireless noise cancelling earbuds.

Sony WI-1000X Wireless

The Sony WI-C600N and the Sony WI-1000X Wireless are similarly performing headphones, but the ANC feature of the WI-1000X make them a more versatile pair of headphones. Their sound profiles are practically the same, but the WI-1000X are good for commuting as it blocks noticeably more low-end frequencies. They also have more battery life, can connect to two devices simultaneously, and can also be used passively with an audio cable, even if their battery is dead. They also have a rigid neckband that feels sturdier than the WI-C600N but isn’t as flexible.

Jabra Elite 65e Wireless

The Jabra Elite 65e Wireless are slightly better headphones than the Sony WI-C600N. Their earbud fit is more comfortable than the typical in-ear design of the Sonys. They also feel noticeably better-built and more durable. The ANC feature of the Elite 65e is also slightly better, and their microphone is noticeably clearer and better for calls. Additionally, you get more battery life with the Jabras. On the other hand, the Sony WI-C600N have a slightly better app and their default sound profile is better, although you can EQ both headphones to your liking. The Sony headphones also support NFC, but can’t connect to 2 devices like the Jabra.

Sennheiser Momentum In-Ear/HD1 In-Ear Wireless

The Sony WI-C600N are better around-the-neck headphones than the Sennheiser Momentum In-Ear Wireless. They are more portable thanks to their malleable neckband and their sound quality is also better, but you can EQ both headphones in their respective apps. They are also noise cancelling in-ears and block a decent amount of ambient noise, which is good for commuting. On the other hand, you get more battery life with the Sennheisers, their latency is lower, and some may not notice the delay when watching video content.

Beats BeatsX Wireless

The Sony WI-C600N are noise cancelling in-ears, but the Beats BeatsX actually block out more noise passively. They also feel more secure inside the ears, which is better for sports. Their neckband design is quite similar and malleable. Sound-wise, they are quite similar, but you can EQ the WI-C600N inside their app, which the Beats are lacking. On the other hand, the Beats take a very short amount of time to fully charge and could have better performance with iOS devices thanks to the W1 chip.

Conclusion

On the upside, they are lightweight and the buds are very small, meaning they won’t make you sweat more than usual when using them.

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.
Score components:
Decent for the office. The Sony WI-C600N do a good job at blocking out work environment noise like ambient chatter and A/C system noise. They also don’t leak, so surrounding colleagues shouldn’t hear what you’re listening to, even at higher volumes. Unfortunately, they don’t support multi-device pairing, so you won’t be able to switch between sources like your PC and phone, and their battery life might not be long enough for a full workday.
5.4TV
Score components:
Sub-par for watching TV. These headphones can’t be used wired, so you won’t be able to get rid of the latency issues they have. Some people may notice a delay between audio and video due to their Bluetooth connection latency. Also, the in-ear fit might not be the most comfortable for watching video content like a movie for hours.
5.2Gaming
Score components:
Poor for gaming. These headphones’ microphone won’t be suitable for online games and their battery life won’t be long enough for long gaming sessions. Also, like most Bluetooth headphones, they have latency issues that will make your gaming experience frustrating as there will be a noticeable delay between audio and video. The Sony WI-C600N shouldn’t be used for this use.
