Sennheiser Momentum True Wireless 2 review - Headphones with goosebumps included

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. 

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. 

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.
