These headphones were replaced by the Sennheiser MOMENTUM True Wireless 4

The Sennheiser MOMENTUM True Wireless 3 are the third generation of the Sennheiser MOMENTUM True Wireless. These premium buds aim to improve and refine their predecessor's performance and design. They look much more reminiscent of Sennheiser's more affordable CX lineup, and those design cues continue with the next generation, Sennheiser MOMENTUM True Wireless 4, too. While the adaptive noise cancelling (ANC) system automatically adjusts to your environment's noise levels, Sennheiser also re-tuned the sound, bringing the earbuds more in line with the manufacturer's audiophile offerings.

Our Verdict

7.1 Neutral Sound

The Sennheiser MOMENTUM True Wireless 3 are decent for neutral sound. They have a more balanced sound than their predecessor, but they still skew bass-heavy due to a dip in their treble range. This dip hurts the comprehensibility of vocals and lead instruments as well as dulls sibilants. On the upside, their companion app offers a 5-band graphic EQ, presets, and sound personalization so that you can adjust their sound.

Pros
  • 5-band graphic EQ available in companion app.
Cons
  • Bad passive soundstage.
7.8 Commute/Travel

The Sennheiser MOMENTUM True Wireless 3 are very good for commutes and travel. They have an adaptive ANC system, which does a good job of reducing background noise like the low rumble of bus engines and passenger chit-chat. Their continuous battery life lasts over eight hours, and their case supplies three additional charges. They're well-built and have a decently comfortable fit, suitable for long trips. An IPX4 rating helps to protect the buds from raindrops or humid days.

Pros
  • Good overall noise isolation.
  • Stable and decently comfortable in-ear fit.
  • Premium build quality.
Cons
  • Bad passive soundstage.
8.2 Sports/Fitness

The Sennheiser MOMENTUM True Wireless 3 are great for sports and fitness. They have three different stability fins, which help ensure that the buds stay in your ear while you're moving, and the buds themselves are well-built and certified IPX4 for resistance against water splashes. They're very portable and lightweight, but their in-ear fit is a little bulky, and the stability fins can be uncomfortable, depending on your ear shape.

Pros
  • Stable and decently comfortable in-ear fit.
  • Premium build quality.
Cons
  • Bad passive soundstage.
7.4 Office

The Sennheiser MOMENTUM True Wireless 3 are decent for office use. These buds have an ANC system that tackles typical workplace noise like ambient chatter and the hum of AC units well. They also leak very little audio at high volumes and have a decently comfortable fit. They last for over eight hours continuously, and their carrying case supplies an additional three charges if you need it. They even support multi-device pairing with up to three devices.

Pros
  • Good overall noise isolation.
  • Stable and decently comfortable in-ear fit.
  • Multi-device pairing with up to three devices.
Cons
  • Bad passive soundstage.
5.6 Wireless Gaming

The Sennheiser MOMENTUM True Wireless 3 are Bluetooth-only headphones and aren't recommended for wireless gaming. They aren't compatible with most consoles, and even though you can use them on Bluetooth-enabled PCs, their latency is likely too high for competitive gaming, even when using aptX Adaptive (Low Latency).

5.4 Wired Gaming

The Sennheiser MOMENTUM True Wireless 3 are truly wireless earbuds, and you can't use them wired.

6.8 Phone Calls

The Sennheiser MOMENTUM True Wireless 3 are alright for phone calls. These buds have an integrated mic with a noise gate to help it separate background noise from your voice. That said, the mic offers an okay overall performance. Your voice lacks body, and speech can be drowned out by loud noise. On the upside, the buds are noise cancelling and can block out a good amount of background noise.

Pros
  • Good overall noise isolation.
Cons
  • Bad passive soundstage.
  • 7.1 Neutral Sound
  • 7.8 Commute/Travel
  • 8.2 Sports/Fitness
  • 7.4 Office

Differences Between Sizes And Variants

The Sennheiser MOMENTUM True Wireless 3 come in three color variants: 'Graphite', 'White', and 'Black'. We tested the 'Black' variant, and you can see our model's label here. 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 True Wireless 3 are the next generation of the Sennheiser MOMENTUM True Wireless 2 and the precursor to the Sennheiser MOMENTUM 4 True Wireless. While they look a lot more like the Sennheiser CX Plus True Wireless than the MOMENTUM 2, there have been a couple of performance-driven changes that help these headphones stand out from the rest of Sennheiser's truly wireless lineup. This manufacturer has significantly improved the buds' ANC, though it falls short of competitors like the Apple AirPods Pro Truly Wireless, the Bose QuietComfort Earbuds Truly Wireless, and the next generation, MOMENTUM True Wireless 4, their ANC is still pretty competitive. They've also re-tuned the sound profile with a bassier and warmer sound, and their 5-band graphic EQ can help out if you want more treble.

Check out our recommendations for the best wireless Bluetooth earbuds, the best noise cancelling earbuds, and the best wireless earbuds for Android.

Sony WF-1000XM5 Truly Wireless

The Sony WF-1000XM5 Truly Wireless are better in-ears than the Sennheiser MOMENTUM True Wireless 3. The Sony are more comfortable, have a more neutral sound profile, which some users may prefer, and have a better noise isolation performance, largely due to their memory foam ear tips, which help form an airtight seal. They also support LDAC, which is a hi-res codec. However, the Sennheiser are better-built and support multi-device pairing with up to three devices simultaneously, one more than the Sony.

Apple AirPods Pro (2nd generation) Truly Wireless

The Sennheiser MOMENTUM True Wireless 3 and  Apple AirPods Pro (2nd generation) Truly Wireless are both premium earbuds. While both are well-built, the Sennheiser have a significantly better battery performance, and you can customize them using their companion software's graphic EQ and presets. In comparison, the Apple are more comfortable and have a more neutral sound profile, which some users may prefer. They also have a better overall noise isolation performance.

Sony WF-1000XM4 Truly Wireless

The Sony WF-1000XM4 Truly Wireless and the Sennheiser MOMENTUM True Wireless 3 are similarly performing headphones, and you may prefer either one. While both have a premium build quality, the Sony headphones have a virtual soundstage feature, and have a better overall battery performance. They also support LDAC, which is Sony's proprietary codec for high-res audio, and have the edge when it comes to noise cancelling. In comparison, the Sennheiser headphones have a more neutral sound profile, which some users may prefer, and they support aptX Adaptive (Low Latency), a codec that helps lower lag in audio and video synchronization.

Jabra Elite 10 True Wireless

The Jabra Elite 10 True Wireless and the Sennheiser MOMENTUM True Wireless 3 are both ANC-capable premium earbuds. The Jabra have a higher IP rating that applies to the buds and the case, a more neutral sound profile, and a slightly better mic. However, the Sennheiser have a better battery life for continuous playback, a bassier sound, and a higher quality codec aptX Adaptive.

Apple AirPods Pro Truly Wireless

The Apple AirPods Pro Truly Wireless and the Sennheiser MOMENTUM True Wireless 3 are both premium in-ears with slight differences. The Apple are more comfortable, have a more neutral sound profile, which some users may prefer, and have a better noise isolation performance. They also offer a few Apple-centric features such as an H1 chip for seamless pairing with your iOS devices and Spatial Audio for a more immersive audio experience. However, the Sennheiser have a better overall battery performance, and their sound profile is more customizable. They can also be paired with up to three devices at a time. 

Sennheiser CX Plus True Wireless

The Sennheiser MOMENTUM True Wireless 3 are better and more premium in-ears than the Sennheiser CX Plus True Wireless. The MOMENTUM 3 are more comfortable, have a more neutral sound profile, which some users may prefer, and they have a significantly better noise isolation performance. They also have longer continuous battery life.

Bose QuietComfort Earbuds Truly Wireless

The Bose QuietComfort Earbuds Truly Wireless have the edge over the Sennheiser MOMENTUM True Wireless 3. While both headphones are well-built and decently comfortable, the Bose have a more neutral default sound profile, which some users may prefer, and they have a more stable in-ear fit. They also have a better overall noise isolation performance. However, the Sennheiser stick out of your ears less.

Sennheiser MOMENTUM True Wireless 4

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.

Sennheiser MOMENTUM 4 Wireless

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.

Bose QuietComfort Earbuds II Truly Wireless

The Bose QuietComfort Earbuds II Truly Wireless are better in-ears than Sennheiser MOMENTUM True Wireless 3. The Bose are more comfortable, and their ANC system can block out significantly more ambient sound. The Bose also have a brighter sound profile. However, the Sennheiser are better-built and have better overall battery life.

Bose QuietComfort Ultra Earbuds Truly Wireless

The Bose QuietComfort Ultra Earbuds Truly Wireless have better noise isolation and feel more comfortable and stable than the Sennheiser MOMENTUM True Wireless 3. While the Bose are more bass-heavy than the Sennheiser, they also have more treble for an overall more excited sound. Both have similar Bluetooth codec support. The Sennheiser mic better separates noise while retaining your voice, although the mic recording quality alone is similar. The Sennheiser also have a better continuous battery life, although the Bose isn't far off.

Beats Fit Pro True Wireless

The Sennheiser MOMENTUM True Wireless 3 are somewhat better in-ears than the Beats Fit Pro True Wireless. The Sennheiser are more comfortable, and feel better built. They also have better battery performance, and their app offers more customization features. However, the Beats have a more stable in-ear fit and a more neutral default sound profile. Their ANC system can also block out more ambient sound.

Jabra Elite 7 Pro True Wireless

The Sennheiser MOMENTUM True Wireless 3 are better in-ears than the Jabra Elite 7 Pro True Wireless. The Sennheiser are better-built, have a better noise isolation performance, and support aptX codec for better audio quality and lower latency via Bluetooth. That said, the Jabra are more comfortable and have a more neutral sound profile out of the box, which some users may prefer.

Bowers & Wilkins Pi7 True Wireless

The Sennheiser MOMENTUM True Wireless 3 are slightly better headphones than the Bowers & Wilkins Pi7 True Wireless. While both headphones have high-end build quality, the Sennheiser are more comfortable, and have a more neutral sound profile, which some users may prefer. They also have a significantly better battery performance, their app offers more customization features, and they support aptX Adaptive. Meanwhile, the Bowers & Wilkins support a wide array of codecs, including aptX HD and aptX-LL, and can block out a bit more background noise.

Sennheiser MOMENTUM True Wireless 2

The Sennheiser MOMENTUM True Wireless 3 are the next generation of the Sennheiser MOMENTUM True Wireless 2 and are an improvement worth checking out. The third generation are more comfortable, have a more neutral default sound profile, which some users may prefer, and their noise isolation performance is significantly better. Their continuous battery life is much longer, and they support aptX Adaptive codec for decreased latency in the Low Latency mode. 

Samsung Galaxy Buds2 Pro True Wireless

The Samsung Galaxy Buds2 Pro True Wireless offer quite a few features limited to Samsung's ecosystem compared to the Sennheiser MOMENTUM True Wireless 3. That includes the Samsung Seamless Bluetooth codec and an Android-only app. They have a more neutral sound profile by default and can block out significantly more background noise. On the other hand, the Sennheiser have the same compatibility regardless of whether you use iOS or Android. They have a much greater continuous battery life, and a mic with better noise handling. You can customize the EQ with more options than just presets as well.

Bowers & Wilkins Pi7 S2 True Wireless

The Sennheiser MOMENTUM True Wireless 3 have a slight edge over the Bowers & Wilkins Pi7 S2 True Wireless. While both buds are decently comfortable and have premium builds, the Sennheiser sound a bit more neutral but can be customized using their companion app's graphic EQ and presets. The buds have a significantly better battery performance, too. Conversely, the Bowers & Wilkins's case also doubles as a wireless transmitter, and they have a better noise isolation performance.

Creative Aurvana Ace 2 True Wireless

The Creative Aurvana Ace 2 True Wireless aren't as good overall as the Sennheiser MOMENTUM True Wireless 3. The Sennheiser's sound quality is cleaner and more neutral sounding, which some may prefer. Noise cancelling and isolation perform much better as well. While the Creative Aurvana Ace 2 True Wireless are packed with the latest xMEMS tech, they don't sound better than the Sennheiser earbuds. Their sound is more bass-heavy with some imaging issues, and the noise cancelling simply isn't as effective, while the battery life is shorter.

The Sennheiser MOMENTUM True Wireless 3 are decently comfortable. Their fit is a step up from the Sennheiser MOMENTUM True Wireless 2, as they're a bit smaller, hurting the ears less. Overall, they're lightweight and come with four differently-sized pairs of ear tips. Using their controls also doesn't push the buds deeper into your ear. However, they're still bulky in design and have a deep in-ear fit. The stability fins can also be uncomfortable, depending on the shape of your ears. However, that'll vary between people, as the stability fins can distribute the weight so it doesn't rest entirely on the ear tip. If you're looking for comfortable ANC in-ears, then check out the Bose QuietComfort Earbuds II Truly Wireless.

The headphones have good touch-sensitive controls. Although they're a little tricky to remember, you have a lot of control with the buds right out of the box. You can also customize controls in the companion app. The controls have lots of tones and voice prompts to let you know when you've registered a command. However, it can be easy to accidentally trigger a command when adjusting the buds since the activation area covers the whole exterior. Some users have also reported that when switching from mono mode to stereo, your audio track can restart. In some cases, the buds will restart any audio, even if they're not placed in your ears, which can drain the battery.

These have an impressive build quality. They feel similarly well-built to their predecessors and are made with dense plastic. The buds have a filter inside the ear tips. Overall, they feel sturdy enough to survive a couple of accidental drops, and they're rated IPX4 for resistance against water splashes. The case is clad in a tweedy fabric with a sturdy magnetic lid. You'll want to pay attention to the stability fins when replacing the buds in the case, as they can shift and prevent the charging contacts from aligning in the case.

The default frequency response of the headphones have a bass-heavy sound profile, mostly due to the recessed low-treble range. However, they still reproduce more bass than the Sennheiser MOMENTUM True Wireless 2, even if you swap out their ear tips for the ones that came with the third-gen. They deliver a touch of extra boom and warmth to mixes, while vocals and lead instruments sound dull. Luckily, you can customize their sound to your liking using their companion app's 5-band graphic EQ to easily make the sound more neutral, for example. When stacked up against their sibling, these are very similar to the Sennheiser MOMENTUM True Wireless 4, and both can be equalized to sound even more alike.

The headphones are very good at controlling their sound profile's peaks and dips. Through the bass and low-mids they're well controlled for relatively accurate, but slightly boomy bass. A small dip in the mid-mid nudges vocals and lead instruments to the back of the mix. A peak in the high-mid makes the upper harmonics of vocals and lead instruments harsh and forward, but a dip in the low-treble weakens harmonic detail. The uneven mid-treble makes sibilants alternatingly dull and piercing.

The Sennheiser MOMENTUM 3 True Wireless' imaging performance is outstanding, indicating that the headphones accurately reproduce and place spatial objects like footsteps in the stereo image.

The group delay falls below the audibility threshold, which results in tight bass and transparent treble reproduction. The L/R drivers of our unit are matched in terms of phase, amplitude, and frequency response. Many of the other Sennheiser headphones we've tested have similar imaging performance, which is indicative of the brand's quality control and ergonomics. Keep in mind that imaging can vary between units, though.

The headphones' passive soundstage performance is bad, which is normal for in-ears. By default, sound doesn't interact with your outer ear, and as a result, the sound seems to be coming from inside your head rather than from speakers placed in the room around you. They also have a closed-back design, so their soundstage seems closed off.

The headphones have a good noise isolation performance. They have an adaptive ANC system that adjusts to the noise around you. They can attenuate bass range sounds like the low rumbles of bus and plane engines well. They can also block out a significant amount of mid and treble-range noise, like ambient chatter and the high-pitched hum of a fan. Isolation, rather than ANC, does most of the work to block noises in the mid to treble range, though. If you'd like better noise cancelling performance, the Sennheiser MOMENTUM 4 True Wireless are a worthy upgrade with more effective attenuation in the midrange and better isolation.

Unfortunately, some users have reported hearing a clicking or glitching noise while the ANC is on. However, we couldn't get our buds into pairing mode to see if this was the case for our unit.

ANC Wind Noise

These headphones have an 'anti-wind' mode, which we used to test ANC wind handling. You can see a comparison between this mode on and off here. The amount of noise depends on the wind angle because of the shape and size of the buds. However, overall, there's still wind noise present, which can be annoying.

Wind noise directly interacts with the ANC microphones, causing loud sounds from the ANC system as it tries to counter it, even though the sound doesn't reach your ears. Using this reduction feature may impact ANC performance if you're in a windy environment.

Speech + Subway Noise Audio Sample

The integrated mic has an okay noise handling performance. Unlike the Sennheiser MOMENTUM True Wireless 2, these headphones have a noise gate. However, it doesn't seem like it improves the mic's performance compared to their predecessor. As a result, the mic struggles to separate your voice from moderate ambient noise. If you're taking a call from a busy street or subway, your voice can get drowned out.

These headphones have a good battery performance. The manufacturer advertises them to last seven hours continuously with their ANC off and with the volume at 50%. However, we reached over eight hours continuously with the ANC on. Battery life can vary depending on use, though. Their carrying case holds an extra three additional charges if you need it, and you can even use one bud while the other charges. There's an auto-off timer that you can adjust in the companion app. The case charges via a USB-C port, or wirelessly on a Qi pad.

The Sennheiser Smart Control app is very good. As of firmware version 2.12.13 there's a 5-band graphic EQ and presets to help you adjust their sound. You can also remap the controls and turn smart pause on and off. You can access Sound Zones, which automatically applies EQ and ANC presets depending on the zone you're in based on the GPS locations you set in the app. In addition, you can access multi-point connectivity, change the settings for transparency mode to play or pause music when using this mode, adjust the auto-off timer, change the voice and tone prompts, and see the battery life. You can even turn on and off the auto-accept call feature.

The Sennheiser MOMENTUM True Wireless 3 have decent Bluetooth connectivity. They support multi-device pairing with up to three devices at a time, meaning you can simultaneously stay connected to your PC, tablet, and smartphone. That said, they have high latency on PCs when connected via SBC, aptX, or aptX Adaptive (High Quality) codecs, and while the aptX Adaptive (Low Latency) reduces audio lag, you might still notice some delay between your audio and video. Some devices and apps compensate for latency, though. While their codec selection is good, the Creative Aurvana Ace 2 True Wireless tops them by including aptX Lossless (which is backward compatible with aptX Adaptive) and the Low Complexity Communication Codec (LC3). If you're looking towards the future, this is a consideration for high-quality audio and low latency.
