Sennheiser Momentum True Wireless 2 review - Headphones with goosebumps included

Sound master. Sennheiser is launching a new edition with the Momentum True Wireless 2 headphones, which convince with a particularly good sound quality. Despite the high price, however, some compromises have to be made in terms of the features offered.

With the Momentum True Wireless 2, Sennheiser is offering in-ear headphones with active noise reduction that are designed to impress with their sound above all. At an MSRP of 299 Euros (~$339), they aren't among the cheapest representatives in the industry. Whether they are worth their price, you can find out in the following review.

Case and ergonomics - TWS headphones with IPX4 certification

The earphones and charging case of the Sennheiser Momentum True Wireless 2 are made of plastic; the latter is also covered with a fabric structure. This gives the case a high-quality look and grippy feel. The workmanship is on a good level and leaves no room for criticism. In addition, the matte surface is not susceptible to dirt. The headphones are available in black and white. 

Sennheiser includes four different sizes of ear tips in the box, so there should be a size to suit everyone. Another positive aspect is that replacement ear tips can be easily ordered from the manufacturer (five pairs of one size for 10 Euros (~$11)). The insertion is a bit unusual at first, since the in-ears have to be twisted slightly into the ear canal for an optimal fit, otherwise there's a risk of a sound deficit, especially in the lower frequency range. The headphones are comfortable, and even with fast and excessive head movements, the Momentum TWS stay in place. In small ears, however, they can sometimes feel tight.

Another positive feature is the IPX4 protection against splashes, so that there's no danger for the headphones even in light rain

Connectivity and handling - Sennheiser headphones with ANC and aptX

The Sennheiser Momentum True Wireless 2 are among the few TWS headphones that also support the high-resolution aptX audio codec. Moreover, they feature active noise cancellation (ANC) and a transparent hearing function, which uses the outside microphones to direct ambient noise directly into the ear when necessary, as we've already seen with the Galaxy Buds, among others. 

The so-called Transparent Hearing can easily be switched on or off with a simple double tap on the right earphone (standard assignment) and provides good communication with the outside world, but it is also accompanied by a quite concise noise.

The operation is done exclusively via the large sensor surfaces on the earphones. The various touch and tap gestures are accompanied by corresponding acoustic feedback, which makes using the earphones easier, but a certain amount of getting used to it is still necessary to get all the gestures working smoothly. This includes the controls for calls, music playback, Transparent Hearing and active noise canceling. The various voice assistants on the connected device can also be activated.

The Sennheiser Smart Control app can be used to define equalizers, configure functions, install firmware updates, and configure the gestures for the sensor surfaces. The app has a very clear design and is available for the Android and Apple mobile operating systems. 

We were able to find a small gap in the features offered by the Sennheiser Momentum True Wireless 2. The carrying case doesn't support wireless charging or quick-charging technology.

Call Quality and noise canceling - Good ANC but only moderate call quality

When it comes to call quality, the Sennheiser Momentum True Wireless 2 deliver mixed results. The user of the TWS headphones is exposed to clearly audible noise, since the ambient microphones are active during a phone call. The person on the other end also perceives this noise but in a greatly reduced way. The Sennheiser wearer is easy to understand in quiet environments but is often accompanied by a hissing noise and sounds quite muffled. Ambient noise is partially filtered out, but people who speak clearly are easily understood. Very loud background noise overloads the microphones so that the wearer can hardly be understood, but for most everyday situations, the provided performance should be enough.

The active noise cancellation works very well in everyday life and significantly reduces the perception of deep ambient noise. During media playback, the background noise can be heard in quiet areas. In environments where ANC makes sense, however, it's swallowed up by the ambient noise. 

Sound - Sennheiser trumps and stabs

With their dynamic 7 mm drivers, the Sennheiser Momentum True Wireless 2 deliver a very balanced sound that is unrivaled among TWS headphones. Whether you're listening to music, podcasts, audio books or movies, the Sennheiser headphones work perfectly and deliver a clear, expansive sound. The mids and lows are resonant and powerful without the basses dominating the sound pattern, while the highs captivate with great precision. Only with classical pieces is it possible to perceive a slight background noise in quieter segments, but otherwise, the Momentum True Wireless 2 have real potential to produce goosebumps.

Battery life - A little more would have been nice

According to the manufacturer's specifications, there should be enough power for up to seven hours of battery life. For this, however, the ANC needs to remain deactivated and the volume shouldn't be turned up too high.

In our test at an adjusted level of 65 dB(A), the battery life is not quite enough for five hours of music reproduction. That's certainly not very long but should be enough in most cases. However, if you're sitting in a plane, you could reach the battery's limits during a medium-haul flight with activated ANC. 

A full charge takes about one-and-a-half hours; the charging case holds a reserve of three additional charges. 

Battery runtime (@ 65 dB) 4 h 56 m

Verdict - Sound reference with minor shortcomings

With the Momentum True Wireless 2, Sennheiser has a more-than-worthy successor in its product range that not only looks good but, above all, manages to convince with outstanding sound in this class of headphones.

It also features a well-functioning active noise-cancellation system. The battery life is certainly not excessively long, but it will surely be enough in most everyday situations.

With the Momentum True Wireless 2, Sennheiser succeeds in creating a real sound master.

Barely any compromises need to be made in terms of features; only the inclusion of wireless charging would've been nice. Frequent callers won't get their money's worth with the Momentum True Wireless 2, since the microphones aren't completely convincing, and the inherent noise is annoying in the long run.

However, if you want to use the Sennheiser TWS mainly as headphones, we can recommend them without reservations.
