The Sennheiser MOMENTUM True Wireless 2 are Bluetooth in-ear headphones. They're the next generation of the Sennheiser Momentum True Wireless, with an added active noise cancelling (ANC) feature and three additional charges in their carrying case. While they isolate you from a fair amount of ambient noise, their ANC is only a slight improvement over their passive noise isolation performance, and their continuous battery life is quite short. They also lack low-bass, and their treble is veiled and dull. Luckily, their companion app has a graphic EQ and presets so you can customize their sound to your liking.

Our Verdict

6.8 Mixed Usage

The Sennheiser MOMENTUM True Wireless 2 are okay for mixed use. They're somewhat comfortable but may not be the best choice if you're wearing them for long listening sessions. They're stable enough for light physical activity, and their noise isolation performance is satisfactory for cutting down office chatter. However, their ANC is only a slight improvement over their passive noise isolation, and they don't do a good job of blocking out noises like the rumble of a bus or train engine. They also struggle to reproduce low-bass, and their treble is uneven and underemphasized. Their high latency and mediocre overall mic performance make them a poor choice for gaming.

Pros
  • Sleek and well-built.
  • Carrying case has three additional charges.
  • App has graphic EQ and presets.
Cons
  • ANC is only a slight improvement over passive noise isolation.
  • Low battery life, even for truly wireless headphones.
  • No NFC or multi-device pairing.
6.4 Neutral Sound

The Sennheiser MOMENTUM True Wireless 2 are unremarkable for neutral sound. They lack low-bass, and their treble is veiled and dull. However, their mid-range is fairly well-balanced, and if you want to tweak the sound, the companion app has a graphic EQ plus some presets. Their in-ear design helps them deliver sound very consistently across users, but also means they can't produce a wide or spacious soundstage.

Pros
  • App has graphic EQ and presets.
Cons
  • Bad passive soundstage.
7.3 Commute/Travel

The Sennheiser MOMENTUM True Wireless 2 are decent for commuting. While they're not the most comfortable for long plane rides, they have a satisfactory active noise cancellation feature. Unfortunately, while their noise isolation performance is satisfactory, their ANC is only a slight improvement over passive noise isolation. Even when on, it struggles to isolate low noise like plane engines. The continuous battery life isn't long enough to last through an overnight flight, but the case can hold roughly three additional charges, which is nice.

Pros
  • Carrying case has three additional charges.
  • Good touch-sensitive controls.
Cons
  • ANC is only a slight improvement over passive noise isolation.
  • Low battery life, even for truly wireless headphones.
7.9 Sports/Fitness

The Sennheiser MOMENTUM True Wireless 2 are very good for sports and fitness. They're compact, easily portable, and stable enough for light physical activity. Some may find them fatiguing to wear for long periods. Still, as they're truly wireless, you don't have to worry about an audio cable snagging on anything while you move, and their touch-sensitive controls make it easy to adjust what you're listening to. They're also rated IPX4 for water resistance, although we don't test for this.

Pros
  • Good stability.
  • IPX4 rating for water resistance.
Cons
  • Low battery life, even for truly wireless headphones.
6.3 Office

The Sennheiser MOMENTUM True Wireless 2 are passable for office use. While they're somewhat comfortable, they can be fatiguing to wear for long periods. Although they have an okay noise isolation performance, their ANC system only offers a slight improvement over their passive noise isolation. That said, it still helps block out background chatter. Unfortunately, their continuous battery life isn't long enough to get you through your day without a pause to recharge.

Pros
  • Good touch-sensitive controls.
  • Great build quality.
Cons
  • Low battery life, even for truly wireless headphones.
  • No NFC or multi-device pairing.
5.2 Wireless Gaming

The Sennheiser MOMENTUM True Wireless 2 are Bluetooth-only headphones and aren't recommended for wireless gaming. They aren't compatible with PS4 or Xbox One consoles, and while you can use them on Bluetooth-enabled PCs or mobile devices, their latency is too high for any competitive gaming.

5.1 Wired Gaming

The Sennheiser MOMENTUM True Wireless 2 are Bluetooth-only headphones and can't be used wired.

6.3 Phone Calls

The Sennheiser MOMENTUM True Wireless 2 are unremarkable for phone calls. The integrated mic captures voice as thin and lacking in detail, but you shouldn't have too much of a problem being understood. However, this mic also struggles to separate voices from even moderately noisy environments, so if you need to make a call, it's best to do so in a quiet space.

Pros
  • Good touch-sensitive controls.
  • Great build quality.
Cons
  • No NFC or multi-device pairing.
  • Mic has mediocre noise handling.

Design
Style

The Sennheiser MOMENTUM True Wireless 2 look almost identical to their predecessor, the Sennheiser Momentum True Wireless. They come in either black or white with a silver metallic accent, and their bulky shape sticks out of your ear. However, they haven't lost the premium look of the previous generation. The only visible difference is that they have several mic holes for their ANC on the earbud.

The Sennheiser MOMENTUM True Wireless 2 are fairly comfortable. Their bulky design can put pressure on the inside of your ear and can cause fatigue if you wear them for long periods of time, especially if you have small ears. On the bright side, they're very lightweight and come with four differently-sized ear tips so you can find the fit that feels best for you.

The Sennheiser MOMENTUM True Wireless 2 have good touch-sensitive controls. They're very similar to the Sennheiser MOMENTUM True Wireless' controls, but they're mappable. By default, most music-related controls like play/pause and track skipping are on the left earbud and are registered by tapping: tap once to play or pause your audio, tap twice to skip to the next track, and tap three times to skip to the previous track. The right earbud turns on/off voice assistant with one tap and turns on/off ANC with three taps. All call management also happens on the right earbud using taps. Controlling volume is fairly easy as you hold down either the left or right ear to decrease or increase the volume, respectively.

The Sennheiser MOMENTUM True Wireless 2 come with a great hard plastic case. This solid case is covered in a grey fabric-like material and should protect the headphones from accidental bumps and drops. While there's no lock to prevent the case from opening up if it falls to the ground, it has a magnet to help keep the earbuds in place.

Build Quality

The Sennheiser MOMENTUM True Wireless 2 have an impressive build quality. They're made of dense plastic and have sleek metal surfaces that also double as touch-sensitive controls. They should survive a few drops or impacts without much damage. The case is similarly sturdy. The earbuds are rated IPX4 for water resistance, although we don't currently test for this.

Design
Stability

The Sennheiser MOMENTUM True Wireless 2 have good stability. They lack stability fins but should still stay in place during runs or other light physical activities. However, they stick out of the ear a bit and could get caught when you're changing your clothes. Luckily, they don't have any audio cables so you don't have to worry about a cable snagging and pulling the earbuds out of your ears.

Update 02/15/2021: We've received user feedback regarding a firmware update to these headphones that may have improved their frequency response. As a result, we've retested their sound profile using firmware update 4.13.0. However, there wasn't a significant change in the frequency response curve. While we don't test the 'High-End Sound Tuning' feature, we also did a pass with this feature turned on. You can see a comparison graph of our results here. The scoring of our sound boxes haven't changed.

The Sennheiser MOMENTUM True Wireless 2 have a somewhat warm sound profile. They lack a bit of low bass, which fans of EDM and hip-hop may find disappointing. The dip in the treble also reduces clarity, which can hurt more vocal-centric audio like podcasts or pop music. Fortunately, you can customize their sound with a graphic EQ in the companion app.

The Sennheiser MOMENTUM True Wireless 2 have great bass accuracy. The low-bass range is underemphasized, so mixes lack a bit of thump and rumble, but the rest of the response is fairly balanced. The slight overemphasis in the high-bass brings warmth and fullness but it shouldn't make your mix overly muddy.

The Sennheiser MOMENTUM True Wireless 2 have bad treble accuracy. The underemphasized low-treble can hurt the comprehensibility of vocals and lead instruments. The mid-treble range is also uneven, so sibilants like S and T sounds may sound alternately dull and piercing.

Dips

The peaks and dips performance of the Sennheiser MOMENTUM True Wireless 2 is okay. The small peak in the high-bass adds a bit of boominess and a shallow dip in the mid-mids that nudges instruments towards the back of the mix. A peak in the high-mids makes vocals and lead instruments sound harsh, and a bigger dip in the low treble hurts their presence and detail. The spike in the mid-treble also makes sibilants sharp and piercing.

The imaging performance of these headphones is great. Their weighted group delay falls below the audibility threshold for the entire range, ensuring a tight bass and transparent treble. Also, the L/R drivers of our unit are well-matched in terms of frequency, amplitude, and phase response, so objects like voices or footsteps are accurately placed in the stereo image. However, these results are only valid for our unit and yours may perform differently.

These headphones have a bad passive soundstage performance. Like most in-ear headphones, they bypass the outer ear, so their sound seems to be coming from inside your head, rather than from speakers set in the room around you. They also have a closed-back design, so their soundstage seems less open than that of most open-back headphones.

The Sennheiser MOMENTUM True Wireless 2 have an okay noise isolation performance. Unfortunately, their ANC is only a slight improvement over passive noise isolation, and some headphones without an ANC feature like the Boltune BT-BH024 Truly Wireless actually have a better noise isolation performance than these headphones. That said, the Sennheiser's passive and active noise isolation can still help to block out mid-range sounds like chatter and reduce higher-pitched noise like the hum of A/C systems. They really struggle to cut down low-bass sounds like bus and plane engines, even when ANC is on.

The Sennheiser MOMENTUM True Wireless 2 have a disappointing battery performance. The manufacturer advertises a seven-hour battery life, but that's with the ANC off. With ANC on, they provide a little over four hours of continuous playtime, which may not be enough to get you through your workday without pausing to recharge them. The case also holds roughly three additional charges, which is convenient, but for the amount of continuous use you get out of these headphones, their charge time is a bit long. There's no power-saving feature either. However, it should be noted that battery performance can vary with real-life use, and your experience may be different.

Update 01/04/2020: We originally reported that the Sennheiser Smart Control app offered a parametric EQ. However, we don't consider this to be a true parametric EQ since you can only adjust a single band frequency. We have updated the Equalizer test results to 'Graphic EQ + Presets' to better represent the app's capabilities.

The Sennheiser MOMENTUM True Wireless 2 have an alright companion app called Sennheiser Smart Control which is available on Android and iOS. With it, you can customize the number of taps and holds for registering commands on both earbuds. You can also turn 'Smart Pause' on or off, which is a feature that pauses the music when you take either earbud out of your ear. The app has a graphic EQ and allows you to create custom presets. While you can toggle the ANC feature on and off, you can't adjust its level.

Update 05/19/2020: We've remeasured both PC latencies. The test results now show a lower latency on aptX than on SBC.

The Sennheiser MOMENTUM True Wireless 2 have decent Bluetooth connectivity. They don't support multi-device or NFC pairing, so you can only connect to one device at a time, and their PC latency is extremely high, even if you're using their aptX codec instead of SBC. However, on iOS and Android, they have no audio lag at all when streaming via Youtube, although this app may be compensating for latency. Other apps seem to compensate for latency, so your mileage may vary with real-life usage.
