The Sennheiser MOMENTUM 4 Wireless are the next generation of the Sennheiser Momentum 3 Wireless. Their design looks much more minimalistic than their predecessor, and there have been a few key updates to their performance. They don't support High-End Sound Tuning, an EQ advertised to create a more dynamic and vibrant audio experience, but that exacerbated driver mismatch in our Momentum 3 unit. Instead of aptX-LL codec support, they utilize aptX Adaptive, which can either provide low latency or allow you to stream high-res audio, depending on your needs. They also have a significantly increased battery life compared to their predecessor and other competitor models like the Sony WH-1000XM5 Wireless.

Our Verdict

7.3 Neutral Sound

The Sennheiser MOMENTUM 4 are decent for neutral sound. Using their 'Flat' EQ preset, they have a slightly bass-heavy sound profile that delivers some extra thump, rumble, and boom to mixes. Vocals and instruments are clear but a bit veiled. Luckily, their companion app offers a graphic EQ and presets to help you customize their sound to your liking. Keep in mind that the headphones are prone to some inconsistencies in audio delivery. If you have thick hair or wear glasses, you may experience a drop in bass.

Pros
  • 5-band graphic EQ and presets available.
Cons
  • Poor passive soundstage.
7.7 Commute/Travel

The Sennheiser MOMENTUM 4 are very good for commutes and travel. These well-built headphones have over 60 hours of continuous playback time, and a comfortable enough fit for long days on the go. They also come with a sturdy hard carrying case to help protect the headphones when not in use. While they have an ANC system, they struggle to cut down the low rumble of bus and plane engines. However, they do a better job of blocking passenger chit-chat while you travel.

Pros
  • Comfortable fit and premium build.
  • Over 60 hours of continuous battery life.
Cons
  • Struggle to block out the low rumble of bus and plane engines.
7.3 Sports/Fitness

The Sennheiser MOMENTUM 4 aren't designed for sports and fitness. They're over-ear headphones, so they're not certified for water resistance, and their fit can fall off with moderate movement. That said, their wireless design ensures that you don't snag something and accidentally pull them off of your head. They're also well-built.

Pros
  • Comfortable fit and premium build.
  • Over 60 hours of continuous battery life.
Cons
  • Poor passive soundstage.
  • Can fall off of your head with moderate movement.
7.6 Office

The Sennheiser MOMENTUM 4 are good for office use. These over-ears have a comfortable fit and deliver over 60 hours of continuous battery life, which is great for long days at the office. They support multi-device pairing, allowing you to stay connected with your phone and computer at the same time. They also have an adaptive ANC system that can help reduce office chit-chat and the hum of computer fans. They don't leak much audio, so even if you like to crank up the volume, your music shouldn't bother nearby coworkers.

Pros
  • Comfortable fit and premium build.
  • Can be paired with up to two devices at a time.
  • Can cut down ambient chatter and the high-pitched hum of fans.
  • Over 60 hours of continuous battery life.
Cons
  • Poor passive soundstage.
  • Mic has mediocre noise handling performance.
5.9 Wireless Gaming

The Sennheiser MOMENTUM 4 aren't meant for wireless gaming. They have high latency using the default codec, so you'll notice lag if connected to your PC or phone via Bluetooth. However, they support aptX adaptive, which provides low enough latency for casual gaming via Bluetooth, but competitive gamers may still find the delay a little too high.

7.3 Wired Gaming

The Sennheiser MOMENTUM 4 are decent for wired gaming if you don't need mic support via analog. They have a comfortable fit suitable for long gaming marathons. Their 'Flat' EQ also has a touch of extra bass, which can help emphasize sound effects like footsteps. It doesn't drown out dialogue and instruments, but these kinds of sounds are a little veiled due to a dip in the high-mid to low-treble. On the downside, their passive soundstage doesn't feel very immersive or spacious. You can still use them via wired USB with full audio and mic compatibility, though their latency is a touch higher over this connection than analog.

Pros
Cons
  • Poor passive soundstage.
6.9 Phone Calls

The Sennheiser MOMENTUM 4 are fair for phone calls. They have an integrated mic, which offers a fair recording quality via Bluetooth, ensuring your voice is understandable. However, the mic struggles to separate your voice from background noise, so if you're taking a call in a busy office, speech can be drowned out. Unfortunately, the mic's recording quality takes a dip if you use the headphones via USB. On the upside, the headphones have an adaptive ANC system that helps reduce a good amount of ambient noise around you.

Pros
  • Can be paired with up to two devices at a time.
Cons
  • Mic has mediocre noise handling performance.
  • 7.3 Neutral Sound
  • 7.7 Commute/Travel
  • 7.3 Sports/Fitness
  • 7.6 Office

Differences Between Sizes And Variants

The Sennheiser MOMENTUM 4 come in two color variations: 'Black' and 'White'. We tested the 'Black' variant. The label is found underneath the ear cup padding and is hard to reach without damaging the padding. Unfortunately, this is also our second unit. The first unit couldn't hold a charge, and we replaced it with another unit, which works as intended.

If you come across another variant of these headphones, please let us know in the forums, and we'll update our review. 

Compared To Other Headphones

The Sennheiser MOMENTUM 4 Wireless are the next generation of the Sennheiser Momentum 3 Wireless. This edition has a new look, and the headphones look more like the Sony WH-1000XM5 Wireless than their predecessor. They've retained a similarly comfortable fit and high-end build quality, but there have been some key changes. They support aptX Adaptive instead of aptX-LL, which is nice if you want to stream hi-res audio or reduce audio latency when watching videos. Sennheiser has also tweaked their sound profile and added more thumpy bass. Their companion app still offers a graphic EQ and presets to help you customize their sound.

Check out our recommendations for the best wireless Bluetooth headphones, the best noise cancelling headphones, and the best headphones for music.

Sony WH-1000XM5 Wireless

The Sony WH-1000XM5 Wireless and the Sennheiser MOMENTUM 4 Wireless are similarly performing over-ears with different strengths. The Sony have a virtual soundstage feature, which helps to create a more immersive audio experience, their ANC system does a better job of blocking out background noise, and they support LDAC codec for hi-res audio. However, the Sennheiser are more comfortable, are better built, and have a significantly longer continuous playback time, and they support aptX Adaptive codec. Their sound is also a bit more neutral, which some users may prefer. 

Bose QuietComfort Ultra Headphones Wireless

The Bose QuietComfort Ultra Headphones Wireless are better than the Sennheiser MOMENTUM 4 Wireless for most purposes. The Bose are higher-end headphones with a much more comfortable fit and a significantly better noise isolation performance. However, the Sennheiser last about twice as long off a single charge, so you might prefer them for long trips or if you don't want to recharge your headphones often.

Sony WH-1000XM4 Wireless

The Sony WH-1000XM4 Wireless have the edge over the Sennheiser MOMENTUM 4 Wireless. While both are premium headphones, the Sony are more comfortable, their ANC blocks out significantly more ambient sound, and they support LDAC, which is a Bluetooth codec for streaming high-quality audio. They also have a virtual soundstage feature to help make your audio seem more immersive and spacious. However, the Sennheiser have a more balanced sound out of the box, though it's still quite bassy. They also have a much longer continuous battery life, and support aptX Adaptive, which is a Bluetooth codec that dynamically adapts to your audio content to give you either lower latency or better audio quality. 

Sennheiser ACCENTUM Wireless

The Sennheiser MOMENTUM 4 Wireless headphones are more premium than the Sennheiser ACCENTUM Wireless. The MOMENTUM 4 are more comfortable, better built, and have a more neutral sound out of the box, which some users may prefer. Their ANC system can also block out more background noise, they last longer on a single charge, and support aptX Adaptive, which is a Bluetooth codec that dynamically adjusts its performance to your content. That said, the ACCENTUM are still a decent option, particularly if you're on a smaller budget. They have most of the same features as the MOMENTUM 4 but don't perform quite as well overall.

Sennheiser ACCENTUM Plus Wireless

The Sennheiser MOMENTUM 4 Wireless have a premium build and feel slightly more comfortable than the Sennheiser ACCENTUM Plus Wireless. The MOMENTUM 4 Wireless use touch controls on both ear cups and have a bit better, but very similar, ANC performance. Their default sound is bass-heavy with neutral mids and a slightly more accurate top-end. While the ACCENTUM Plus Wireless has a slightly brighter treble, finessing their app's EQ for either pair of headphones can make them sound more alike. The ACCENTUM Plus Wireless can connect via aptX Adaptive to prioritize audio quality or reduce latency. Their mic sounds a bit worse but handles environmental noise better. You also only get touch controls on the right ear cup instead of on both ear cups, and their build quality isn't as premium.

Apple AirPods Max Wireless

The Apple AirPods Max Wireless and the Sennheiser MOMENTUM 4 Wireless have different strengths. While both headphones are well-built, the Apple have a more immersive passive soundstage, support Spatial Audio, which can help make your audio seem more immersive, and are able to block out significantly more background noise. They also have an H1 chip for seamless pairing with your Apple devices. However, the Sennheiser are more comfortable and have a slightly more neutral sound profile. They also have a significantly longer continuous battery life, have sound customization features, and support multi-device pairing. 

Focal Bathys Wireless

The Focal Bathys Wireless and Sennheiser MOMENTUM 4 Wireless share similar aptX codec compatibilities, USB-C, and analog listening capabilities. By default, the Sennheiser have more rumble in the low end and a more accurate treble response. Plus, they have a significantly better battery life. The Focal have better noise isolation and a more neutral sound profile overall, with a mic that handles noise better than the Sennheiser. The Focal also yield a more predictable sound than the Sennheiser between multiple wears. Both headphones have comprehensive apps for adjusting EQ and ANC levels. A deciding difference for many consumers is that the Sennheiser are priced in a lower bracket, while the Focal sit in a higher price tier.

Sennheiser Momentum 3 Wireless

The Sennheiser MOMENTUM 4 Wireless are the next generation of the Sennheiser Momentum 3 Wireless. The fourth generation have a different look than their predecessor and lack High-End Fine Tuning, so their sound profile is more bass-heavy. Their battery life is significantly better, they support aptX Adaptive, and they come with a sturdier carrying case. However, the Momentum 3 have a better noise isolation performance and support aptX-LL. 

Bowers & Wilkins Px7 S2 Wireless

The Sennheiser MOMENTUM 4 Wireless and the Bowers & Wilkins Px7 S2 Wireless are both good headphones, but the Sennheiser have a slight edge. While both headphones are comfortable, the Sennheiser have a more neutral sound profile, although it's still pretty bassy, and have a significantly longer continuous battery life. They're also more customizable. On the flip side, the Bowers & Wilkins are better-built and have a more stable fit.

Bose QuietComfort 45/QC45 Wireless

The Bose QuietComfort 45/QC45 Wireless and the Sennheiser MOMENTUM 4 Wireless are similar headphones with different strengths. If you want headphones for your commute, the Bose are much more comfortable and have an ANC feature that blocks out significantly more noise. However, the Sennheiser support aptX Adaptive, which you can use to stream higher quality audio or lower latency when you're watching videos. They also have a much longer continuous battery life. 

Shure AONIC 50 Gen 2 Wireless

The Sennheiser MOMENTUM 4 Wireless have the edge over the Shure AONIC 50 Gen 2 Wireless. While both headphones feel premium and have similar levels of noise isolation, the Sennheiser have a more neutral default sound, which some users may prefer, and their continuous battery life is significantly longer. Their companion app also offers a lot more customization features. However, the Shure have a built-in DAC, giving you better sound quality via wired USB.

Bowers & Wilkins Px8 Wireless

Depending on your needs, you may prefer either the Sennheiser MOMENTUM 4 Wireless or the Bowers & Wilkins Px8 Wireless. The Sennheiser have a more neutral sound profile, although it's still bass-heavy, and a longer-lasting continuous battery life. Conversely, the Bowers & Wilkins are more comfortable and better-built. They also have a better noise isolation performance.

Sennheiser MOMENTUM True Wireless 3

The Sennheiser MOMENTUM True Wireless 3 and the Sennheiser MOMENTUM 4 Wireless have different strengths and depending on your usage, you may prefer either one. While both pairs of headphones have a premium build and great noise isolation performances, the True Wireless 3 are lighter, more portable, and stable, thanks to their in-ear design. They're less prone to inconsistencies in audio delivery too. However, the MOMENTUM 4 are over-ears and more comfortable. They have a significantly better battery performance.

The Sennheiser MOMENTUM 4 look more like the Sony WH-1000XM5 Wireless than the Sennheiser Momentum 3 Wireless, so they have a sleeker design than the previous gen. Sennheiser has removed the metal hinge design and opted for a plastic frame with cloth detailing. The manufacturer's logo is printed on the lower part of the headband. These headphones come in two color variants: 'Black' and 'White'.

These headphones are lightweight and comfortable for most people. The headband is comfortable, and they don't clamp too tightly on your head. However, depending on the size of your ears, they may touch the driver housing inside the ear cups. If you have a large head, you may also have trouble getting a good fit. The headband can put a bit of pressure on the top of your head, but it's not as fatiguing as the Sony WH-1000XM5 Wireless.

The Sennheiser MOMENTUM 4 have great controls. There's only one button and a touch-sensitive surface on the right ear cup, which is easy to use. There's also a unique pinching movement you can use on the touch surface to adjust the strength of the ANC and transparency modes. However, to use this command, adaptive ANC needs to be off in the app. The touch-sensitive surface is also a bit too responsive, and you can accidentally register a command if you move the headphones on your head. There are beeps to let you know when you've registered a command, as well as voice prompts for a Bluetooth connection. However, the volume and track-skipping beeps are the same tones. You also need to use the app for some features to be active.

Power button:

  • Single press: Mutes and unmutes the mic.
  • Press and hold: Turns the headphones on and off.

The touch-sensitive surface on the right earcup:

Build Quality

We had to order a second unit as the first pair of headphones we purchased was defective and couldn't hold a charge. Our second unit doesn't have this issue, but our experience may indicate issues in quality control. If you've had the same problem, please let us know in the forums. However, assuming you don't get a defective unit, they have a great build quality. The headphones are mostly made of plastic with a silicone and cloth headband, as well as faux leather ear cups. The plastic ear cups attract fingerprints, which is a bit annoying. Overall, these headphones feel solid and sturdy but not as well built as the Bowers & Wilkins Px8 Wireless, which have an aluminum and brushed metal frame.

Stability

They're decently stable. They shouldn't move around much if you're casually listening to music at your desk or while walking around. However, they can fall off your head with more intense head movements.

When using the 'Flat EQ', these over-ears have a bass-heavy sound profile that delivers extra thump and rumble to mixes. It's well-suited for genres like EDM and hip-hop, but if you prefer a different sound, their companion app offers a graphic EQ and presets. You can see a comparison of the EQ presets here. You can also see a comparison of the 'Bass Boost' and 'Podcast' modes here, which you can also enable at the same time as any other preset in the app.

Unlike the Sennheiser Momentum 3 Wireless, the Sennheiser MOMENTUM 4 don't support this manufacturer's High-End Fine Tuning feature. Instead, there's Sound Personalization, which is a 5-band EQ that's based on your own listening preferences. This feature will ask you to listen to a song and choose between different settings. Compared to the Sennheiser ACCENTUM Plus Wireless, these sound quite similar, like a variation on the same basic tuning. However, the MOMENTUM 4 exhibit a slightly more laid back upper midrange affecting vocal presence and a more even treble response for better detail in the harmonics of cymbals.

They have good bass accuracy. The low to mid-bass is overemphasized, resulting in extra thump and punch in your mixes, which is great for genres like EDM and hip-hop. The overemphasis can also be heard in songs like Help I'm Alive by Metric, as the ever-present kick-bass has intense presence throughout the song, slightly overpowering the vocals. The high-bass is fairly flat and neutral, so mixes have warmth but little boominess.

The Sennheiser MOMENTUM 4 have excellent mid accuracy. The low to mid-mid are well-balanced and flat, which results in present and clear vocals and lead instruments. It can be heard in acoustic songs like The Sound of Silence by Simon & Garfunkel, as both vocalists' voices are well-present in the mix. Although there's a dip in the high-mids, which weakens vocals and instruments, it's fairly minor.

These headphones control their sound profile well. A bump in the low-bass adds thump and rumble mixes, while a peak between the mid-mid pushes vocals and lead instruments to the front of mixes. The high-mid is uneven, so the upper harmonics of vocals and instruments are alternatingly weak and harsh. A peak in the mid-treble makes sibilants like hi-hats piercing.

While our Sennheiser Momentum 3 Wireless unit has mismatched driver issues, and it seems like their High-End Fine Tuning feature makes it worse, these headphones don't have that feature and are very well-matched. This results in the accurate placement of objects like voices in the stereo image. Keep in mind that imaging can vary between units and can be an indication of the manufacturer's quality control and ergonomics.

They also block out more overall sound than their more affordable counterpart, the Sennheiser ACCENTUM Wireless.

However, these headphones don't have an ANC off mode and can only switch between ANC on and transparency mode. As a result, we tested the passive noise isolation with the headphones off.

The integrated mic has a fair recording quality. Your voice sounds fairly clear and easy to understand. We used an estimated value for LFE as the processing job is recording LFE at -3dB by default, which doesn't reflect its real performance. To account for this, we measured LFE at -6dB, as this is the point in the response that we feel is closest to the true LFE. Even though there isn't much bass in the recording quality, it's not as bad as the graph indicates. We are looking into this issue, though.

Users have reported a drop in mic audio quality when using the headphones via USB. When we connected our unit to our PC using this connection, and played a track, recording halfway to mimic a conference call. You can hear the recording here (it's quite loud, so you may want to lower your audio before playing it!). Although there's slight hissing coming from our speaker in the testing box, there's also a noticeable drop in audio quality, which can be frustrating if you want to use them for work calls. Keep in mind that the recording only shows the difference between USB and Bluetooth mic audio quality and doesn't demonstrate the sound quality of the headphones.

After updating to firmware 2.13.18, the app now offers a 5-band graphic EQ, customizable presets, and a Sound Check feature, which is a custom EQ that uses settings you select after listening to your favorite songs. You can also access the sound personalization feature, which allows the buds to provide sound based on your individual and unique hearing as well as sound zones, which change the EQ and ANC settings based on your location. There are ANC controls, so you can turn the ANC on and off and adjust the Wind Noise Reduction settings. You can adjust the sidetone, turn head detection on or off, see which codecs are being used, and reset the headphones. You can activate High-Resolution Audio mode, which allows you to use aptX Adaptive codec for streaming audio in higher quality or with lower latency, depending on what you want. You can also use Sleep Mode to lock and unlock touch controls.

These headphones come with a 1/16" to 1/16" TRS cable so you can use them wired. You can also connect the headphones via USB-C to receive audio. However, you can't use the mic that way. Also, their USB latency is higher than analog, so there will be very slight lip sync delays if you're streaming video over this connection.

These headphones have good Bluetooth connectivity. They support multi-device pairing, so you can stay connected to your phone and computer at the same time. Like the Bowers & Wilkins Px7 S2 Wireless, they also support aptX Adaptive and are backward-compatible with aptX HD, which can help stream hi-res audio content with better audio quality. That said, latency is high with the default codec, SBC, as well as higher-quality codecs like aptX and aptX Adaptive (High-Quality), and delays are noticeable between the audio you hear and the visuals on screen. It's not a big deal if you're only streaming audio, but you'll want to stick to aptX Adaptive (Low Latency) if you're watching videos. Some apps and devices compensate for latency differently.

We also checked how Sennheiser's 'Audio Resolution' and 'Standard' modes affect latency. However, when using aptX Adaptive (High Quality), both modes performed very similarly at over 350 ms. As a result, we expect both Bluetooth modes to perform the same. The mid-tier Sennheiser ACCENTUM Plus Wireless support a similar set of Bluetooth codecs with lower latency when using aptX Adaptive (High Quality), although you'd still notice lag if you tried watching video, and their low latency codec results are similar.
