Design

Score components:
Sennheiser Momentum True Wireless Design Picture

The Sennheiser True Wireless are very well-built headphones. They feel solid enough to survive a few accidental drops and their charging case protects them well. They are also splash resistant (IPX4) and their design is very portable. Unfortunately, the in-ear fit isn’t the most comfortable, but they do come with 4 different tip sizes for you to find the best fit. People who like physical activity will like their breathability and stable fit. However, they do have a bulky design for in-ears and people with smaller ears might find them less comfortable and not as stable.

Style
Sennheiser Momentum True Wireless Design Picture 2

These headphones are nice-looking truly wireless earbuds but have a bulky design. The housings are thick and large, protruding out of your ears quite a bit. They have a premium look thanks to the dense plastic and metal touch-sensitive surface on the back of the buds. They only come in a black color with the metallic circle accent.

6.5 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

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 Sennheiser Momentum True Wireless headphones are not the most comfortable in-ears we’ve tested. Their bulky design may touch the interior of your ear and apply some pressure, which will result in fatigue after a while. This will be most noticeable for people with smaller-sized ears. However, they come with 4 different tip options for you to find the most comfortable fit and they are very lightweight.

7.6 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.

Additional Buttons : No

The Momentum True Wireless have a good and responsive touch-sensitive control scheme that may take some time to get used to. The left earbud is the command center for everything related to music. One tap plays/pauses, two taps skips forward, and three taps skips backward. The right earbud is for call management. One tap answers/ends calls, two taps rejects calls. When no calls are coming in, one tap triggers your device voice assistant while two taps controls talk-through. Holding down the left earbud also lowers the volume while holding the right one raises it. These headphones also have a smart pause feature, meaning as soon as you take out an earbud, the music will stop. However, if you pause your music manually with the left earbud, then take it out, music will start playing again, which seems to be an oversight or a bug. On the upside, you also have voice prompts for min/max volume and while pairing the headphones.

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:

The provided charging case that comes with the Sennheiser Momentum True Wireless is great. It is a solid case that protects the headphones from scratches, water exposure and impacts, and is better than other true wireless earbuds like the Jabra Elite Active 65t. However, there is no locking mechanism and the case can open if it falls on the ground, exposing the headphones. They might also fall out if the impact is significant but the magnets do help keep the earbuds in place.

8.0 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.

The Momentum True Wireless are very well-built headphones, similarly to the B&O Play Beoplay E8. They look and feel like premium headphones. They are made out of dense plastic and nice metal surfaces that act as touch-sensitive controls. They should survive a few accidental drops without too much damage. The case is also very well-made and feels sturdy. The earbuds are also rated IPX4 for sweat and splash resistance, but we do not currently have a test to accurately measure this.

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
Sennheiser Momentum True Wireless Stability Picture

These truly wireless headphones are stable enough for running and light physical activities. They don’t have stability fins like more sports-oriented headphones, but the in-ear fit is good enough so they don’t pop out of your ears. They also don’t have a cable, eliminating the risk of it getting hooked on something or stuck on clothing. People with smaller ears may have worse stability performance due to the bulky design of the headphones.

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.)
Sennheiser Momentum True Wireless Frequency Response

The Sennheiser Momentum True Wireless are average sounding closed-back in-ears. They have a powerful, thumpy and consistent bass, a well-balanced mid-range, but a sub-par treble. Unfortunately, their bass is also slightly boomy and their mid-range is a bit cluttered making vocals and instruments sound thick and muddy. Their treble range is rather uneven and underemphasized, resulting in a lack of detail and brightness on vocals, leads and cymbals. However, some S and T sounds may feel piercing for some users. Overall, these headphones are decent for bass-heavy music, but may not be the ideal choice for vocal-centric genres.

8.3 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:

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
:
4.04 dB

The Momentum True Wireless have a very good bass range performance. Their LFE (low-frequency extension) is at 10Hz, which is excellent. They also have a flat low-bass and mid-bass that are within 2dB of our target curve. Combined with the excellent LFE, this results in a deep and punchy bass capable of producing low thump and rumbles. However, high-bass is overemphasized by 4dB, resulting in an overall bass range which is deep and punchy, but slightly boomy and muddy.

8.7 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:
Sennheiser Momentum True 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
:

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
:
2.5 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
:
-0.73 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
:
0.32 dB

The mid-range is very good. The response is quite even and mostly flat. The low-mid overemphasis, which is the continuation of the high-bass bump, adds a bit of muddiness to vocals/leads and clutter to the mix. However, at 2.5dB, this effect will be subtle. There is also a shallow dip in mid-mid, slightly nudging the vocals to the back of the mix, but this will barely be noticeable.

5.3 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:
Sennheiser Momentum True 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
:
5.68 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
:
-6.61 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
:
-1.58 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
:
-0.03 dB

The treble performance is sub-par. The overall response is rather uneven and quite underemphasized, especially in low-treble. The broad dip will negatively affect the detail and brightness of vocals and lead instruments. On the other hand, the peak at 11KHz will make some sibilances (S and T sounds) feel sharp and piercing. Overall, they will have a darker sound.

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.
Score components:
9.1 Frequency Response Consistency
What it is: The amount of deviation of each frequency response pass, from the average frequency response.

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

8.9 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.
Sennheiser Momentum True Wireless Group Delay Sennheiser Momentum True 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.

The stereo imaging is excellent. Their weighted group delay is at 0.13, which is very low. The group delay graph also shows that the entire response is well below the audibility threshold. This ensures a tight bass and a transparent treble reproduction. Also, the L/R drivers of our test unit were well-matched in frequency, amplitude, and phase response. This is important for the accurate placement and localization of objects (voices, instruments, video games effects) in the stereo image. Note that these results are only valid for our unit and yours may perform differently.

1.1 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.

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
:
2.7
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
:
0.1
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 is poor. This is because creating an out-of-head and speaker-like soundstage is largely dependent on activating the resonances of the pinna (outer ear). The design of in-ears and earbuds is in such a way that fully bypasses the pinna and doesn't interact with it. Also, because these headphones have a closed-back enclosure, their soundstage won't be perceived to be as open as that of open-back earbuds like the Apple AirPods, Google Pixel Buds, or the Bose SoundSport Free.

8.0 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:

The Sennheiser Momentum True Wireless have a good harmonic distortion performance. In the bass range, they show very little THD, even under heavy loads, which is good. However, the peak in THD at 1KHz may add a bit of harshness and impurity to the sound of those frequencies. On the upside, there is no big jump in THD at 100dB SPL, which may be due to the flexibility of the drivers under heavier loads.

8.1

Isolation

Score components:

The Sennheiser True Wireless isolate well passively and are even better than some noise canceling headphones. If you can get a good seal with the provided tips, they will prevent a decent amount of ambient noise from seeping into your audio. They also barely leak, which makes them a suitable option to use on the bus, train or at work. You'll be able to raise your listening volume without disturbing people surrounding you.

The Sennheiser Momentum True Wireless have an above-average isolation performance. They only passively block noise as they don’t have any ANC features. In the bass range, occupied by the rumble of airplane and bus engines, they reduce the noise by about 8dB, which is about average. However, this is rather impressive for an in-ear, and more than what some active noise canceling headphones achieve. In the mid-range, important for blocking out speech, they achieved 22dB of isolation which is very good. In the treble range, occupied by sharp S and T sounds and fan noise like A/C systems, they achieved more than 49dB of isolation, which is excellent.

9.9 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.

The Sennheiser Momentum True Wireless' integrated microphone has a sub-par performance. In quiet environments, speech recorded or transmitted with this mic will sound thin and muffled. However, speech will still be decently understandable, but slightly sharp sounding. In noisy situations, they will struggle to separate speech from ambient noise, even in moderately loud environments like a busy street.

5.1 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.
Score components:
Sennheiser Momentum True Wireless Microphone Frequency Response
Recorded Speech
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
:
403.18 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
:
7.36 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.
When it matters: HFE is one the most important factors in speech intelligibility. The higher the HFE, the brighter, more open, and more extended the speech quality will be which makes it a lot easier to understand by the listener.
Good value: >8KHz
Noticeable difference: 1KHz
:
3568.48 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
:
11.168
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
:
23.82 dB

The recording quality of the microphone is poor. The LFE (low-frequency extension) of 403Hz means speech recorded/transmitted with this mic will sound noticeably thin. The HFE (high-frequency extension) is at 3.6KHz, resulting in speech that lacks detail and sounds a bit muffled. The bumps between 750Hz and 3.5KHz could make speech on this microphone a bit too sharp sounding.

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.
Score components:
Sennheiser Momentum True Wireless SpNR
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
:
15.12 dB

The microphone is mediocre at noise handling. In our SpNR test, it achieved a speech-to-noise ratio of 15dB, indicating that they are best suited for quiet environments. However, in moderate and loud environments, they will have difficulty separating speech from ambient noise.

The Momentum True Wireless have sub-par battery life as they only offer 3.7 hours of playback on one charge. Thankfully, the case offers 2 additional charges, bringing the total battery life to about 11-12 hours. They can easily last you a workday if you take breaks to charge the buds. Unfortunately, they don’t have any power saving feature to extend their battery life. On the upside, you can see the amount of battery left in each earbud inside the app.

Update: 13/02/2019: The Sennheiser Momentum True Wireless have a passive battery drain issue that has been corroborated by a lot of users in the discussion threads. Since we do not yet have a fully developed test for passive battery drain/ battery leak, we have not made any changes to the battery score of the review for now. Once we have an accurate way to measure this effect, the review will be updated.

6.5 App Support
What it is: The additional app provided to enhance your listening experience. They typically deliver a set of practical features that give you more control over the sound, noise cancelling and effects that the headphones produce.

The Momentum True Wireless headphones are compatible with a new Sennheiser app called Smart Control. When connected to your phone, you have access to small customization options such as a graphic EQ, which acts more like presets. You can move a cursor around, choosing to boost/lower bass or treble frequencies. This isn’t as useful as a 5-band EQ. You can also activate talk-through directly from the app, and you can enable smart pause, which pauses the music when you take out one of the two earbuds. However, manually pausing your music with the left earbud, and then taking it out, will result in music unpausing in the right earbud.

Compared to other Headphones

Sennheiser Momentum True Wireless Compare Picture

The Sennheiser Momentum True Wireless headphones are decently versatile headphones but are slightly disappointing for their price point. They have poor treble performance and have a short 3.7-hour battery life, which is lower than other truly wireless headphones in this premium price range. Nevertheless, they have a more complete and responsive control scheme and have good isolation performance, useful during commuting and at the office. See our recommendations for the best truly wireless earbuds.

Bose SoundSport Free

If sound quality is your biggest criteria, the Bose SoundSport Free are the better headphones. They have a good audio reproduction and are versatile for a wide variety of music genres. They will also sound a bit more open due to their semi-open design. However, this means they don’t isolate ambient noise well like the Sennheiser Momentum True Wireless and will leak significantly more. The Bose companion app also doesn’t offer any sort of customization options and the buds’ control-scheme is hard to use, while the touch-sensitive area of the Sennheisers is easy to use and responsive.

B&O PLAY E8

The Sennheiser Momentum True Wireless and B&O PLAY E8 are very similar headphones, even in design. They have the same style and perform quite similarly in most of our tests. However, the E8 are significantly more comfortable and have slightly longer battery life, with a useful auto-off timer. On the other side, the Sennheisers have better wireless range, support lower latency codecs, and offer a few more features like a talk-through function on the earbuds.

Jabra Elite Active 65t

The Jabra Elite Active 65t are better headphones than the Sennheiser Momentum True Wireless. They are more neutral-sounding, and you can also use the more complete 5-band EQ available in the Jabra mobile app. They also have better battery life and can connect to two devices, which is convenient. On the other hand, the Sennheisers have amazing wireless range and a nice touch-sensitive control scheme that offers more functionalities. Their case also feels better-made and they support lower latency codecs.

Apple AirPods

The Sennheiser Momentum True Wireless are better truly wireless headphones than the Apple AirPods. They are more versatile thanks to their closed-back design and their touch-sensitive control scheme is responsive and easy-to-use. They are better suited for sports and have more bass to keep you pumped. They also have better isolation and leakage performance. On the other hand, the AirPods have better battery life and are significantly more comfortable than the Sennheisers. However, they can only be used with iOS devices.

Jabra Evolve 65t

The Jabra Evolve 65t are better truly wireless earbuds than the Sennheiser Momentum True Wireless. They have a more accurate sound, especially in the treble range. Their microphone is also better when using the provided dongle on PC. They have great battery life on a single charge and you can EQ their sound to your liking, which you can’t do on the Sennheisers. On the other hand, the Momentum True Wireless have a more premium feeling and feel better-built. They also support lower latency codecs which can be useful if your source supports them too.

Conclusion

6.8Mixed Usage
What it is: This is the combination of the different use cases to evaluate how versatile the headphones are. Therefore an everyday headphone should be well-rounded enough to adapt to most situations and environments without significant losses in sound quality, design ergonomics or isolation.
Score components:
Decent for mixed usage. Their sound profile is better suited for bass heavy genres, but won't be ideal for more vocal-centric music. Also, the in-ear fit, may not be the most comfortable for critical listening. They have a good isolation performance which makes them an above-average option for commuting and to use at the office. Also, they are very portable and stable enough for light physical activities but are on the bulkier side for in-ears. Unfortunately, they are sub-par for watching TV and gaming as their default latency is too high, but they do support lower latency codecs.
6.7Critical 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:
Okay for critical listening. They have a thumpy and consistent bass, a well-balanced mid-range, but their treble performance is sub-par. The detail and brightness of vocals, leads and cymbals are negatively affected by the broad dip in the treble range, making them better suited for bass-heavy genres than vocal-centric music. However, you can EQ them with the companion app, even if their graphic EQ is not the best.
7.3Commute/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.
Score components:
Above-average for commuting and traveling. These compact in-ears have good noise isolation performance and barely leak, meaning you can raise your listening volume to block even more ambient noise. Also, they are fairly comfortable for short trips like bus rides, but the in-ear fit is not ideal for long flights.
8.0Sports/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.
Score components:
Great for sports. These truly wireless headphones are portable, breathable and don’t pop out of your ears during physical activity. They have a bulkier design than most in-ears, so people with smaller ears might not experience an as stable fit.
7.0Office
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. They isolate ambient chatter very well and will let you concentrate on your tasks, without bothering colleagues, since they barely leak any sound. However, they have short battery life on one charge, so you will need to take breaks to recharge them. Also, the in-ear fit might not be ideal to wear during a whole workday.

Sub-par for watching TV. While they have excellent wireless range, which would let you enjoy your favorite movies from your couch, their default latency may be too high for some. However, they do support lower latency codecs, but you’ll need an appropriate dongle to use them, and even then, you might still feel like what you see isn’t matching what you hear.
5.0Gaming
Score components:
Bad for gaming. These in-ears aren’t comfortable for long gaming sessions and their latency is a bit too high, even with lower latency codecs. Also, if you’re playing online, their microphone performance is sub-par and it is not a good option to communicate with friends and teammates.
