Sennheiser Momentum True Wireless Review

Personal audio solutions are a giant market, and there are a huge variety of earbuds and headphones available to choose from. Some offer niche functions, some focus on sound-shaping options, while others aim for specific uses like gaming or commuting, etc.

Regardless of the features, functions, or form, the main trend is towards wireless connections. Specifically, Bluetooth connectivity.

As the number of Bluetooth earbuds continues to increase in popularity and demand, more and more companies are wading into these waters. One such company is Sennheiser. Being one of the world’s best manufacturers of audio capture and reproduction, it was only natural for Sennheiser to roll out a pair of Bluetooth earbuds.

So, have they added to their repertoire or missed the mark?

Let’s find out in our in-depth Sennheiser Momentum True Wireless review…

Sennheiser Momentum True Wireless
Our rating:4 out of 5 stars (4 / 5)

The Build and Design

One of the first things people look for in earbuds is the quality of the construction. There are plenty of very inexpensive earbuds with poor build quality and flimsy construction. That is why they are cheap!

These earbuds are anything but cheap or flimsy. Sennheiser is known for their high standards of design and construction. For the most part, they have stayed true to their reputation with the Momentum earbuds.

Clearly, a lot of thought went into designing these earbuds. In fact, these are a real step forward for Sennheiser. Since they deal mostly with microphones and studio/broadcasting equipment, these are a welcome advancement.

A fine finish…

These earbuds are sculpted to look and feel lovely. They feature metallic details on the outer face and gold-plated charging pins. Indeed they look sleek and stylish.

Finding a fit for everyone…

Did you know the human ear is a more accurate identifier than even fingerprints? It is true! Every ear is different, and Sennheiser took this to heart when they built these earbuds.

A slim and lightweight design means you can wear these for extended periods without discomfort. Each earbud weighs just a little more than six grams.

Likewise, they feature an ergonomic ear canal type of coupling. This means they fit in your ears and not over or around. It is actually a very comfortable design since your ears do not get as sweaty as headphones. Nor do you have something rubbing or pressing on large areas of the ears.

Size options and added protection…

To provide an ideal fit for all types of ears, there are four different sizes of soft silicone ear tips included. There are S, M, L, and XS sizes to choose from. Furthermore, the ear tips work to enhance sound isolation. Along with an ergonomic design and multiple ear tip sizes, these earbuds feature an IPX4 rating. This means they are splash-proof and can get wet with no real issues.

However, if you happen to drop them in the bath, they are unlikely to survive. That said, any kind of perspiration will not cause damage.

Based on how these earbuds look and feel, there is no doubt they offer amazing construction quality.

The Battery

These earbuds use rechargeable built-in Lithium-ion batteries in each earbud. You can expect up to four hours of playtime on a single charge.

Secure storage…

Additionally, there is a handy carrying case to store these earbuds when not in use. Furthermore, this is not just a cloth sack. The carrying case has molded foam inside so that the earbuds are secure and protected.

In fact, you can charge the earbuds with a USB cable while they are in the case! The case is a charging dock with its own battery. This increases the playback time from four hours to 12 hours. And you get a USB-C charging cable as part of the package. That is a huge bonus in our book.

The Controls and Connections

Right away, you will notice there seem to be very few controls. They are quite small, after all. But the diminutive size hides some very intuitive controls.

Touchpad controls…

Both of the earbuds have built-in touch controls. You can play or pause audio, answer or end calls, and activate voice assistants with just a single tap on the right earbud to engage either Google Assistant or Siri.

That is about it for physical controls on these earbuds. Everything else is either voice-activated or relies on Sennheiser’s advanced automatic technology.

Intelligent earbuds…

The moment you take one earbud out of your ear, they automatically turn off. Likewise, as soon as you put it back in your ear, they power up. This helps to conserve the battery and also means you do not have to worry about forgetting to turn them off.

The Auto On/Off also works when you put the earbuds in the carrying case.

Hassle-free connections…

The Momentum True wireless earbuds feature Bluetooth 5.0 connectivity. You can connect to both iOS and Android devices.

The Bluetooth connection is solid and delivers lag-free audio in real-time. Plus, these earbuds use technology that ensures perfect synchronization between the left and right earbuds.

The codecs used for the wireless connection are aptX and AAC.

Customize your sound…

As with most wireless earbuds, the Momentum True earbuds come with an app. The Smart Control app works with both iOS and Android devices.

This app lets you configure the earbuds. As well as customize the equalizer and sound settings.

The Sound

As with audio equipment, the sound is everything. As far as we are concerned, the Sennheiser Momentum True Wireless earbuds excel in this department.

Components and specs…

Inside these very tiny earbuds, you find dynamic speakers with a frequency range of 5 Hz – 21,000 Hz, which can handle every kind of musical genre. Plus, the sound pressure limit is a generous 107 dB.

The result is highly-detailed, accurate, and dynamic sound reproductions. Even more impressive when you consider how small and light these earbuds are.

Staying aware…

Featured with these earbuds is Transparent Hearing. You can lose yourself in the music while remaining aware of your surroundings.

Essentially, there is good noise-cancellation and sound isolation, but also allowing for important sounds to be heard. You will still hear sirens, horns, announcements, and even people calling your name.

Keeping in touch…

Being that these earbuds feature voice assistants, there has to be a microphone. If there is one area where these earbuds do not amaze, it is the mic.

The microphone is a MEMS (micro-electro-mechanical-systems) type of mic. If you have never heard of this kind of mic, you are not alone. These are relatively new and are often called “mic chips” or “silicon mics.”

A MEMS mic works on an analog-to-digital principle and typically requires some kind of preamp for optimal performance.

A minor downside…

Unfortunately, there is no preamp in these earbuds. Therefore, the sound capture is thin compared to built-in lavalier microphones. Conversely, the sound quality is not terrible. Simply, underwhelming. And somewhat surprising, seeing as this is a Sennheiser product.

All in all, with an SPL of 98 dB and a frequency range of 100 Hz – 10,000 Hz, the microphone does its job. Just not to the level one would expect from Sennheiser.

Sennheiser Momentum True Wireless Review Final Thoughts

We have to admit there are some very impressive features with these earbuds. The automatic on/off function when you take them out of your ears is one such feature. Another is the battery charging option found in the carrying case.

The sound quality is what we expected from Sennheiser. It was exceptional. However, we did find the microphone lacking in performance. But, this is because it is a MEMS mic, and those types of mics are still being refined.

On the other, the comfort, high-quality build, intelligent controls, and dynamic soundstage more than make up for a less than ideal microphone.

Basically, these are high-performance wireless earbuds when it comes to sound. And they have the added benefit of working seamlessly with Android and iOS voice assistants.

That’s all for now. Until next time, happy listening.
