Sennheiser updates its flagship line with the latest Sennheiser MOMENTUM True Wireless 4 earbuds. These Bluetooth and active noise cancelling (ANC) earbuds look very much like the last generation, with tweaks to the previous model, the Sennheiser MOMENTUM True Wireless 3's, design and included technology while not trying to reinvent the wheel. One of the standout additions to the feature set seeks to futureproof the wireless earbuds: Auracast, which connects to local open Bluetooth audio broadcasts. So, can these earbuds tick off all the boxes to make them your next pick?

Our Verdict

7.2 Neutral Sound

The Sennheiser MOMENTUM True Wireless 4 earbuds are decent for neutral sound. By default, their frequency response is warm with dark treble and somewhat boosted bass. Their EQ allows you to brighten the treble or go wild and make them sound bassier—it's up to you. They also support a wide gamut of Bluetooth codecs, including aptX Adaptive (High Quality) for streaming your audio at a higher bitrate. As in-ear fitting buds, they don't have an open or immersive passive soundstage.

  • Five-band EQ in the app.
  • Passive soundstage isn't open or immersive.
8.1 Commute/Travel

The Sennheiser MOMENTUM True Wireless 4 are great for commuting and traveling. Their adaptive noise cancelling with adjustable strengths allows you to choose how much you want to filter out the din of an airplane cabin. The continuous battery life can last most national flights, while the case provides three additional charges. They feel comfortable, although smaller ears can encounter some discomfort over longer listening sessions, and you can choose between three stability wing sizes (or none) alongside their ear tips for a good fit. They scarcely leak any audio, so you won't bug fellow passengers even when it's lights off during a red-eye flight. Using their companion app, you can adjust the sound to suit your tastes and customize controls at your fingertips.

  • Adaptive noise cancelling does an excellent job.
  • Good battery life.
  • Supports multi-device pairing and Auracast.
  • Can cause discomfort over long sessions for some folks.
8.3 Sports/Fitness

The Sennheiser MOMENTUM True Wireless 4 are great for sports and fitness use. They're portable and pocketable, and thanks to the included stabilizer wings and ear tip selection, you can really dial in their fit for stability. They have an IP54 rating against water splashes, so you can take them for an outdoor run if it's raining. Most controls are available through the touchpads without needing to consult your phone, while their ANC helps you focus on your goals at the gym without distractions.

  • Very stable fit.
  • IP54 rating against dust and water.
  • Can cause discomfort over long sessions for some folks.
7.6 Office

The Sennheiser MOMENTUM True Wireless 4 earbuds are good for office use. Their noise handling filters ambient noise around the office and clangs from the shared kitchen well, although if there's rumbling construction, they don't filter as much noise. They barely leak any audio, so you won't disturb your coworkers regardless of the volume you set them at. Their multi-device pairing lets you switch between your phone and work computer easily. The buds sound good for most music and vocal-centric media, plus you can EQ them. You can easily access all of their controls via the touchpads. Their battery might barely make it through the full workday (depending on usage), but you can recharge them during a meeting. However, if you have small ears, they can cause discomfort after wearing them for hours.

  • Adaptive noise cancelling does an excellent job.
  • Supports multi-device pairing and Auracast.
  • Controls easily accessed with touchpads.
  • Can cause discomfort over long sessions for some folks.
  • Mic doesn't filter noise exceptionally well.
5.7 Wireless Gaming

The Sennheiser MOMENTUM 4 True Wireless aren't suitable for wireless gaming. Even though they support aptX Adaptive (Low Latency), they still have enough latency that audio can lag. This depends on your device and connection strength. They'll also only connect to Bluetooth devices, so you can't use them with PlayStation or Xbox consoles.

5.5 Wired Gaming

You can't use the Sennheiser MOMENTUM 4 True Wireless for wired gaming because they're Bluetooth-only earbuds.

7.3 Phone Calls

The Sennheiser MOMENTUM 4 True Wireless are decent for phone calls. Their noise cancelling helps isolate you from the environment to better hear the caller. Their dedicated phone controls are accessible via the touchpads, and you can enable an auto-accept mode for phone calls. Their mics capture your voice fine, but your voice sounds somewhat thin. In quiet environments, that's totally useable. However, they don't handle environmental background sounds well, leaving your voice sounding unnatural and sometimes overwhelmed by loud noises like passing trains.

  • Controls easily accessed with touchpads.
  • Mic doesn't filter noise exceptionally well.

Differences Between Sizes And Variants

The Sennheiser MOMENTUM True Wireless 4 are available in three colors. Our unit is 'Black Graphite' (you can see their label here), and the other two colorways are 'Black Copper' and 'White Silver.' Besides the cosmetic differences, these are all the same model. Please let us know in the comments if you encounter a different variant.

Compared To Other Headphones

The Sennheiser MOMENTUM True Wireless 4 represent an incremental update to the previous Sennheiser MOMENTUM True Wireless 3, with virtually the same dimensions, fit, and design. Most notably, the updated model has better noise isolation performance. They stack up well to the Sony WF-1000XM5 Truly Wireless' ANC, and while both are premium buds, a few differences will come down to taste, like sound profile preferences, whether you prefer the LDAC Bluetooth codec on the Sony or the aptX codec selection on the Sennheiser.

Check out the best noise cancelling earbuds, the best wireless Bluetooth earbuds, and the best sounding wireless earbuds for more options to suit your needs.

Sony WF-1000XM5 Truly Wireless

The Sennheiser MOMENTUM True Wireless 4 and Sony WF-1000XM5 Truly Wireless are both very competitive premium earbuds. Both are neck and neck regarding their noise isolation, with the Sennheiser filtering a bit more midrange-y noise and the Sony blocking a bit more bright trebly noise. The Sennheiser's default sound profile is warmer and balanced in the mids, with a bit of boom, which you can EQ. Both earbuds support quality Bluetooth codecs, with the Sennheiser using aptX Adaptive (Low Latency, High Quality, and aptX HD). However, if you care about virtual surround sound, only the Sony headphones support that. The Sony are slightly less chunky and use memory foam ear tips to isolate and secure their fit. Their sound is more boomy and bright, but you can also EQ them. They support LDAC Bluetooth codec, and their wireless range is greater.

Sennheiser MOMENTUM True Wireless 3

The Sennheiser MOMENTUM True Wireless 4 are better by most metrics than the Sennheiser MOMENTUM True Wireless 3, but not by an enormous margin. Updates to the 4 include better noise cancelling that reduces more midrange noise like ambient traffic din and low-humming HVAC units. By default, they sound slightly less bassy, but you can EQ either pair to sound alike. They're also slightly more futureproof with the Auracast feature, which isn't widely supported but allows you to receive local Bluetooth audio over open feeds, such as airport announcements. They have added dust resistance with an IP54 rating. On the other hand, the 3 have a slightly longer battery life, and you can use multi-pair to connect to up to three devices rather than just two on the 4. However, while their noise isolating is good, it's not as effective.

Apple AirPods Pro (2nd generation) Truly Wireless

The Apple AirPods Pro (2nd generation) Truly Wireless are aimed at Apple users with special considerations like the H2 chip for improved connectivity and switching between Apple devices on the same account. They also feature virtual surround sound. Their noise cancelling is comparable, but the Apple buds reduce low rumbling sounds more. Their sound is brighter overall, but you have less control over it, and the codec selection is more limited. If you don't have an iOS device, you won't have as much control or access to features. Their continuous battery life is notably shorter. The Sennheiser are more stable but have a more invasive fit. You can use their app regardless of whether you use an Apple or Android device. Their noise cancelling handles wind noise better, and their sound is easier to tailor using the equalizer. For Android users, their aptX Adaptive compatibility offers higher-quality audio streaming or lower latency. They also have multi-device pairing.

Bose QuietComfort Ultra Earbuds Truly Wireless

The Sennheiser MOMENTUM True Wireless 4 and Bose QuietComfort Ultra Earbuds Truly Wireless have a lot in common, like their similar battery lives. Both earbuds support aptX Adaptive, including aptX Adaptive (Low Latency). Only the Sennheiser support multi-device pairing and wireless case charging. Their sound is less excited in the highs and lows, with a five-band EQ. Their noise isolation reduces more midrange noise consistent across the frequency spectrum. They also have dust resistance with an IP54 rating, instead of just water resistance on the Bose's IPX4 rating. However, they're not as comfortable as the Bose. You're less likely to accidentally trigger a command on the Bose because they're easier to grip. These have a bassier and brighter sound profile by default, and you have an EQ but with only three bands. Of the two, only the Bose earbuds include virtual surround sound. Their noise cancelling filters out more low, rumbling noise, like engines on a bus, and they do a similarly great job of blocking high-pitched noises.

Technics EAH-AZ80 True Wireless

The Sennheiser MOMENTUM True Wireless 4 and the Technics EAH-AZ80 True Wireless are premium buds with premium feature sets. They both offer a comparable battery life performance and are similarly well-constructed. The Sennheiser have a more balanced bass and mid-response with their default sound profile, but the Technics have a more accurate treble response. While both provide a great level of attenuation against ambient sound, the Sennheiser have the edge here, blocking out more external noise across the entire frequency range. That said, the Technics have a more comfortable fit and LDAC support, and they feature three-way Bluetooth multi-device connectivity for staying connected to multiple devices on the go.

The Sennheiser MOMENTUM True Wireless 4 bear a lot of resemblance to the previous generation Sennheiser MOMENTUM True Wireless 3, sharing similar earbuds and almost identical cases. The buds are chunky and squarish, with rounded edges and optional silicone stabilizers. They look premium, with a semi-matte metallic finish, a shiny logo on each touchpad, and either black or white interior-facing plastic. Your color choices are 'Black Copper,' 'Black Graphite,' and 'White Silver.'

Weight 0.03 lbs
Clamping Force
0 lbs

These buds feel decently comfortable. They're lightweight, and you've got a choice of four ear tips and the option to wear one of the three pairs of included stabilizers to help you dial in the fit. Still, if you don't like a deep in-ear fit or if you have small ears, they can feel invasive and bulky with their weight distributed unevenly. Because their touch controls are located directly outside your ear canal, rather than on the stems like the Apple AirPods Pro (2nd generation) Truly Wireless, you may find that using the touch controls causes discomfort.

OS Compatibility
Not OS specific
Ease Of Use Okay
Feedback Good
Call/Music Control Yes
Volume Control Yes
Microphone Control No

Noise Cancelling Control On/Off
Additional Controls Voice Assistant

The Sennheiser MOMENTUM True Wireless 4's controls are good. The capacitive touchpad registers commands predictably. However, due to their shape and large touch surface area, you can accidentally trigger a command when adjusting the earbuds, which is annoying. Otherwise, they emit clear tones for each command you enter, except if you max out the volume (which we don't recommend for your health), and then the sound prompts get drowned out by the audio playback.

Otherwise, you can reassign most of the controls in their companion app, like transparency mode (which pipes in the external sounds of your environment) and noise cancellation. Your reconfigurable gestures are single, double, and triple taps, as well as press-and-hold commands, and the commands don't have to be the same for both earbuds. The only two options you'd have to manually add are locking and unlocking the touchpad or assigning no control to any given touch command. Every other remappable command is included in the default controls seen below, and you can change any of them except for the factory call controls.

Left earbud:

  • Single tap: Enable transparency mode, accept incoming calls, or mute the current call.
  • Double tap: Skip to the previous track, reject incoming calls, or end the current call.
  • Triple tap: Turn ANC on/off.
  • Press and hold: Decrease the volume.

Right earbud:

  • Single tap: Play/pause audio, accept incoming calls, or mute the current call.
  • Double tap: Skip to the next track, reject incoming calls, or end the current call.
  • Triple tap: Activate voice assistant.
  • Press and hold: Increase the volume.

Both earbuds:

  • Press and hold both simultaneously: Enter Bluetooth pairing mode.

The charging case for the Sennheiser MOMENTUM True Wireless 4 is great and is virtually identical to the Sennheiser MOMENTUM True Wireless 3. It's shaped like a rectangle with rounded edges. The plastic case is covered in a tweed-like fabric, which varies depending on the colorway you choose. Its magnetic lid feels reliable, and you can charge it via the included USB-C port on the front or with a wireless charging pad. A small LED indicates the case or earbuds' battery and charging status.

Build Quality

Like the previous generation, the Sennheiser MOMENTUM True Wireless 4's build quality is impressive. The buds feel lightweight and premium, with nice finishing and tight seams. They have an IP54 rating against water splashes and dust for the buds, which is an upgrade over the previous generation's IPX4 rating against water only. You get four ear tips, three sets of stabilizing wings made of good-quality silicone, and replaceable filters to cover the drivers. Their charging case is a bit more stout and made of denser feeling plastic than the midrange Sony WF-C700N Truly Wireless. It's possible that if you treat the case carelessly, the tweed can wear down, but it won't impact the effectiveness of the case.


Their stability is great. Through a combination of a good fit achieved through the right ear tip size and wings, these headphones stay put slightly better than the last generation and are lighter and more stable. You can easily exercise with these without worrying that they'll dislodge.

Sound Profile
Bass Amount
-0.05 dB
Treble Amount
-2.33 dB

The Sennheiser MOMENTUM True Wireless 4 sound warm and neutral by default. Their low to mid-bass is slightly restrained when delivering rumble to sub-bass synths. Due to the laid-back low and mid-bass and recessed treble, the boom of kick drums in the high-bass is punchy but not rumbly, and the lead instruments come across with focus in the balanced mid range. This yields clear guitars, keyboards, and bass guitars. Vocals come through as natural but not very bright. By default, the sibilants (like S and T sounds) of vocals and cymbals sound somewhat veiled and inconsistent.

In any case, If you like the warm sound the previous Sennheiser MOMENTUM True Wireless 3 provide, then you'll like the similarly tuned 4th-gen. This tuning is a pretty easy one to finesse using their app's EQ—whether you listen to EDM or folk music—because of how conservative and smooth it is by default.

Frequency Response Consistency
Avg. Std. Deviation
0.32 dB

Their frequency response consistency is excellent. Using the correct fitting ear tip and stabilizer wing allows the earbuds to deliver predictable bass, mid, and treble. We had trouble getting the bud to fit our rig's right ear, so our results from the right ear have a little more variation than the left, but that's not because the right earbud is less consistent. This isn't something that you will experience in real life, though.

Raw Frequency Response

1.61 dB

The Sennheiser MOMENTUM True Wireless 4 have remarkable bass accuracy. It supplies kick drums and bass instruments with a consistent amount of boom and thump. It's not going to give you that deep thump in tracks like Praia Do Norte (Club Edit) by Molecule, but you can EQ that to taste.

Mid Accuracy
Std. Err.
1.18 dB
1.4 dB
-0.8 dB
-0.01 dB

The Sennheiser MOMENTUM True Wireless 4's mid accuracy is fantastic. As a result, lead instruments and vocals sound true to their audio mix. Only a slight dip midway through the mids causes leads and vocals to sit slightly down in the mix, but the bass and treble responses help to make this very subtle.

Treble Accuracy
Std. Err.
4.3 dB
-3.57 dB
-3.33 dB
-2.94 dB

Their treble accuracy is decent. The low to mid-treble is underemphasized, pushing harmonic detail and clarity of vocals and cymbals down in the mix, and warming them up. The rest of the treble is somewhat uneven, with a slight emphasis on sibilants (like S and T sounds), although the response isn't bright and airy.

0.82 dB
1.16 dB

The Sennheiser MOMENTUM 4 True Wireless' peaks and dips performance is excellent, indicating they control their sound profile well. Through most of the bass, they're accurate, with a wide but shallow peak in the high-bass to low-mid, yielding a good amount of thump and a bit of added boom. The minor dip, followed by a larger peak in the mid range and where the mids transition into the low-treble, nudges lead instruments down slightly while adding more intensity. The largest dips and peaks are in the treble range, where the dips dull and darken the harmonics of vocals and cymbals, while the peak adds sharpness.

Weighted Group Delay
Weighted Phase Mismatch
Weighted Amplitude Mismatch
Weighted Frequency Mismatch

Their imaging performance is good. This indicates the headphones have good ergonomics and aligns with the results of other headphones we've tested by the manufacturer, suggesting tight quality control. The headphones' group delay yields tight bass and transparent treble. There's a small bump in the mid and high-mid's phase response, but it isn't audible with real-world audio playback. The amplitude exhibits a bit of mismatch between the left and right drivers in the mids, which slightly shifts the stereo image between both drivers, but it's not very obvious unless you're listening for it. Imaging can vary between units, so our results are only valid for our unit.

Passive Soundstage
PRTF Accuracy (Std. Dev.)
PRTF Size (Avg.)
PRTF Distance
Acoustic Space Excitation

The earbuds' passive soundstage performance is bad. That's expected with closed-back, in-ear fitting headphones because they bypass your outer ear, which ordinarily helps you to process direction and distance. As a result, your audio sounds like it's coming from inside your head instead of within the room around you, and it's not open or immersive.

The Sennheiser MOMENTUM True Wireless 4's weighted harmonic distortion performance is satisfactory. Like the previous Sennheiser MOMENTUM True Wireless 3, these have distortion present in the low-treble that peaks between the low and mid-treble regions. It's not obvious in real-life content.

These are the settings used to test these headphones. Our results are only valid when using them in this configuration.

Noise Isolation - Full Range
Noise Cancelling Yes
Overall Attenuation
-23.88 dB
-15.78 dB
-27.19 dB
-30.06 dB

The Sennheiser MOMENTUM True Wireless 4's full range noise isolation performance is excellent. The earbuds use adaptive noise cancelling, which is adjustable in the app, with a wind reduction mode as well. They filter low rumbling engine noise, but not as well as they reduce mid range ambient sounds like traffic and speech. They also isolate bright and piercing sounds like shrieking subway brakes and dish clatter well.

During testing, the earbuds would turn off while we tried to get a good seal in our testing rig's head. We've alerted the rig's manufacturer, and it's a known issue, but most importantly, it doesn't impact your actual experience of the earbuds and their noise cancelling. In other words, they don't turn off when you, a human, wear them. We could measure noise isolation during testing using a single earbud. However, because both earbuds need to be operational and fitted into the testing rig, the following tests don't have recordings: Noise Isolation - Common Scenarios, Noise Isolation - Voice Handling, and ANC Wind Handling.

Noise Isolation - Common Scenarios
Airplane Noise Attenuation
-21.64 dB
Airplane Noise Isolation Audio
Office Noise Attenuation
-19.71 dB
Office Noise Isolation Audio
Street Noise Attenuation
-19.51 dB
Street Noise Isolation Audio

They do an excellent job of handling the noise of everyday life situations. Their combined adaptive noise cancelling and isolation reduces the sounds of a busy street, the ambient din inside of an airplane cabin, and the usual noise inside an office effectively.

Unfortunately, due to how these buds interact with our test rig, we couldn't capture audio recordings. There's more on this in Noise Isolation - Full Range. Fortunately, this doesn't affect their performance in the real world.

Noise Isolation - Voice Handling
Female Voice 1
Male Voice 1
Female Voice 2
Male Voice 2

Unfortunately, due to how these buds interact with our test rig, we couldn't capture audio recordings. There's more on this in Noise Isolation - Full Range. This doesn't affect the ANC performance in real-life circumstances.

Depending on your needs, you may want to block out all sounds—including voices—or hear them clearly while reducing other external sounds. If you're in the former camp, the ANC significantly reduces (but doesn't completely block) how loud people's voices sound. However, if you want to follow a conversation, speech is still understandable but more difficult to hear if audio is playing simultaneously.

ANC Wind Handling
ANC Wind Noise

The Sennheiser MOMENTUM True Wireless 4 have a mode in their companion app to reduce noise that results when exterior ANC mics interact with the wind hitting the capsules. Their ANC handling with the mode turned on produces similar results at all angles. You'll still hear a bit of environmental noise, but it's quieter than without noise cancelling enabled. Check out this comparison of their wind handling with ANC on, ANC with wind reduction mode, and ANC off. Leaving the wind reduction mode on when you're not in a windy environment can impact their ANC performance.

Unfortunately, due to the interaction of the buds with our testing rig, we couldn't capture audio recordings. There's more on this in Noise Isolation - Full Range. However, this doesn't impact the experience of using the earbuds in real life.

Leakage Audio
Overall Leakage @ 1ft
21.8 dB

The Sennheiser MOMENTUM 4 True Wireless have incredible leakage performance. Due to the deep in-ear fit, they block your ear canal and successfully tamp down on audio escaping. What little escapes is very quiet even if you listen to music at high volumes, so you won't disturb folks nearby.

Their mic's recording quality is good. The earbuds use beamforming microphones, which aren't fully compatible with our testing rig, but even so, they sound good. Captured speech is intelligible and bright, if lacking body, and sounding a touch too sibilant and sharp. The caller on the other end will certainly understand you.

Noise Handling

The mic's noise handling performance is mediocre. With consistent background noise, their mics struggle to fully separate your voice from the unwanted noise and cut some of the higher frequencies of your voice as a result. You'll still be intelligible to the caller, but you won't sound completely natural. The mics struggle more with handling sudden and loud noises and can completely cut out portions of your speech altogether.

The Sennheiser MOMENTUM True Wireless 4's battery performance is good. The manufacturer advertises their total battery life, including the charging case, to last 30 hours with volume at 50% and ANC off. Our standard testing yielded just under seven and a half hours of continuous battery life with ANC enabled and set to max, so they'll get close to that 30-hour figure, including the case with their three extra charges. The case recharges in just under an hour, which is quick, and you can eke out an hour of playback with eight minutes of fast charging. You can charge the case via its USB-C port or with a wireless charging pad.

The Sennheiser MOMENTUM True Wireless 4 use the Sennheiser Smart Control app, and it's great. You can look at the app here. You get adjustable ANC modes, including a wind mode. For folks who want to stay aware but also like to control the ratio of how loud your music is in relation to how loud the transparency mode is, you can adjust that, too. There's a five-band equalizer with presets and custom modes to tune their sound profile. You can control the Bluetooth codec selection and multi-device pairing. Their controls are remappable, and you can toggle on the auto-accept feature for incoming calls or lock the touch controls altogether. The earbuds' auto-off timer is adjustable in the app as well. Sound Zones requires you to make an account and allow location tracking permissions, and when enabled, you can create preset listening settings for various locations. This allows you to seamlessly move from your office, where you might have ANC maxed out, to wind mode or transparency mode when you step outside without doing anything besides setting it up in advance.

The Bluetooth connectivity of the Sennheiser MOMENTUM True Wireless 4 is decent. They have multi-device pairing with up to two devices, which is controllable through their app. You can use aptX Adaptive (Low Latency) to reduce the lag between audio and video media. Depending on your device, connection, and app, you'll still probably notice a bit of lag, but it's not distracting. While aptX Adaptive (High Quality) and aptX HD support higher resolution audio, they also cause more latency, but it's fine for music and podcasts. There's no LDAC support, as with the Technics EAH-AZ80 True Wireless, though.

One significant difference is that, unlike the previous generation, they support Auracast. While support for the Bluetooth feature is rare, and we don't currently test it, it's meant to allow localized Bluetooth audio broadcasts without requiring confirmation for your headphones to connect to the device streaming the audio. One example of Auracast's utility is for transmitting airport announcements, so passengers can listen to any updates without needing to remove their earbuds. The feature hasn't been widely adopted, but that doesn't mean it won't be helpful down the line.
