Sennheiser Momentum True Wireless 2 Bluetooth in-ear headphones review

A few years ago completely wireless in-ear headphones were unthinkable. That has now changed and there are numerous suppliers of True Wireless in-ear headphones. Among them is the well-known German premium audio brand Sennheiser.

With the Momentum True Wireless 2, the company now even offers the second generation. Compared to the first version, the earpieces have become smaller, but at the same time the battery life has increased and active noise suppression has been added. Of course, the in-ears also offer IPX4 certification, so they are protected against splash water. We took a closer look at the premium class Momentum True Wireless in-ears.

Excellent first impression

The Sennheiser Momentum True Wireless 2 will be delivered in typical Sennheiser packaging with a blue and white design. Both the charging box and the in-ears will please right out of the box. They make an absolutely high-quality impression and the design also appeals to me very much, even if this is of course a matter of taste.

The loading case is covered with fabric that fits very tight and does not wrinkle. The lid, on which the Sennheiser logo is emblazoned, simply folds upwards. The folding mechanism is crisp, so the charging case cannot open accidentally. Inside, the in-ears can then be used for charging. They are then held in place by quite strong magnets so that they cannot fall out even if the charging box is upside down.

How is the wearing comfort?

Sennheiser supplies four different silicone earmoulds at once. The sizes XS, S, M and L are designed to provide the right one for every ear. Unfortunately, however, foam earpieces have not been included.

Once you have found the right attachments, you can insert the Momentum True Wireless 2 into the ear. It is important to choose the right attachment to ensure that the ear is well sealed and the bass is not lost. With a slight turn the in-ears are fixed in the ear.

Even though Sennheiser has reduced the size of the Momentum True Wireless 2 compared to its predecessor, small ears can still feel a feeling of pressure. Even though many reviewers praise the wearing comfort, I have to say that it was not ideal for me. The Creative Outlier Gold were more comfortable for me. But I also had a tight fit with the Sennheiser Momentum True Wireless 2. Ultimately, every ear shape is different, so the only thing that helps here is to try it out.

Current standards for transmission

The Sennheiser Momentum True Wireless 2 is one of the first in-ear headphones to use the latest Bluetooth 5.1, which is very commendable. And because Bluetooth is backwards compatible, using it on older players is of course no problem.

In addition, the codecs SBC, AAC and aptX are supported so that high quality transmission is possible.

Pairing the Momentum True Wireless 2 is quick and easy. To do this, both touch surfaces must first be pressed for three seconds to put the in-ears into pairing mode. Unfortunately, it’s not possible to pair several devices at once, so that you always have to reconnect when changing devices.

The Bluetooth connection is stable and we haven’t had any dropouts in our everyday use. The right earpiece can also be used separately, but the control does not change, so you may have to reprogram it yourself to continue to have a useful control.

Control by touch

The in-ears are controlled via touch surfaces, which are located on the outer sides of the device. You can reach the in-ears quite well without having to access the user interfaces.

Operation of the touch surface Left Right
1x touch play/pause, call answer/end Voice assistant, call answer/end
2x taps next title, reject call transparent hearing, reject call
3x taps previous title Active Noise Cancelling
Hold lower volume increase volume

The control system works reliably. There is a delay of approx. 1.5 seconds until the respective action is executed in order to detect possible multiple inputs. The acoustic feedback is especially positive here, as a pleasant beeping sounds with each typing, whose pitch changes depending on the repetition, so that it’s quite easy to recognize how many times you’ve already pressed.

If the right in-ear is taken out of the charging box during a phone call, the incoming call is also automatically accepted. In addition, the Momentum True Wireless 2 is equipped with a sensor that detects when you take it out of your ear and then pause the music playback.

More control via app

Sennheiser provides users of its headphones with the Smart Controll App. This can also be used with Momentum True Wireless 2 in-ear headphones. Here, users are guided through the setup, but can also make various settings.

Right at the start of our test, we were suggested a firmware update to the current version 4.6.0. According to the app, this takes up to 50 minutes, which is unusually long and in fact the update takes quite a long time. On the positive side, however, it is possible to continue using the in-ear headphones during the update process. You have to be a bit careful if you have a battery-constrained smartphone, which may close the app automatically in the background. But the process can be continued later.

Besides the updates you can also make various settings. Starting with a simple equalizer, which probably does more harm than good, there are also many useful options. For example, the assignment of the touch surface of the two earpieces can be completely changed so that you can adapt it to your preferences.

Furthermore, the sidetone, auto answer, smart pause, active noise reduction, transparent hearing and even the complete touch control can be activated or deactivated.

The ambient sound directly to the ear

Transparent Hearing is a feature that more and more high-priced headphones offer. The Sennheiser Momentum True Wireless 2, for example, picks up external noise from the built-in microphones and passes it on, so that despite the seal provided by the (hopefully) matching earpieces you can still hear everything from the outside world. The music is either paused or continues to play when activated.

Basically, this feature works very well with the Momentum True Wireless 2. I even had the feeling that I heard better than before. Also the tracking works perfectly. What is noticeable, however, is a slight background noise, which is not particularly disturbing.

Active noise cancelation

It is amazing how much technology fits into these small wireless in-ear headphones. The Momentum True Wireless 2 can filter out low-frequency ambient noise through external microphones. This works quite reliably and there is also no increased background noise or other negative influence on the sound. Sennheiser has implemented Active Noise Cancelling (ANC) very well.

How good does the Sennheiser Momentum True Wireless 2 sound?

The 7 mm drivers of the in-ears cover a frequency range from 5 to 21,000 Hz. This is decent and probably more than some people can hear.

The sound of the Sennheiser Momentum True Wireless 2 is terrific. They deliver a balanced and warm sound that blends harmoniously. Despite the high dynamic range, the sound is always precise and powerful, creating a spatial stage that is truly unique. So if you’re looking for in-ears with good sound, you’ve come to the right place.

How long does the battery last?

Sennheiser states that the Momentum True Wireless has a running time of seven hours. If they are recharged again with the battery integrated in the charging case, they will last for up to 28 hours. These figures are achieved at around 50 percent volume without active noise suppression, which is a good value. With ANC the whole thing is then reduced to just under five hours.

If the earpieces are empty they can be recharged quite quickly. Ten minutes in the charging box will give you about 90 minutes of running time, and it takes about 90 minutes to fully charge. The charging box is recharged via USB-C. An LED indicates the battery status at any time. When the in-ears are in the box, the LED shows the battery status of the in-ears, if they are not in the box, the LED shows the battery status of the charging box.

Conclusion on the Sennheiser Momentum True Wireless 2 Test

With a price of 299 euros (current: € 196.98 *), the Sennheiser Momentum True Wireless 2 is not cheap. But they are worth their price.

The workmanship is absolutely top quality and the feature set is extensive. I especially like the Transparent Hearing, but also the active noise reduction works great.

Of course, the sound and wearing comfort are particularly important. I was also absolutely convinced by the sound of the in-ear headphones, but the wearing comfort was not completely convincing, as I felt a slight pressure. However, since everyone has a different ear shape and many reviewers have found the Momentum True Wireless 2 to be comfortable to wear, my problems shouldn’t scare you off. If the price doesn’t scare you off, try them for yourself.

The Sennheiser Momentum True Wireless 2 are outstanding in-ear headphones that deliver both features and sound. Wearing comfort wasn't the issue for me, but as everyone has a different ear shape, potential customers should try the in-ears for themselves.
