Audio
Momentum True Wireless ranks among the very best in its class in terms of sound performance, alongside the WF-1000X.
They deliver a very good listening experience and stand out above all by a very wide and balanced frequency response. Although there is a slight signature in W (accentuation of the extreme bass, midrange around 2 kHz and treble around 8 kHz), respect for timbre is assured, no frequency band takes precedence over another (no masking effect disturbing the legibility of the sound scene ). Each element of the sound scene finds its place and is easily identifiable. Although we have already seen more reactive chouia membranes (on the WF-1000X), the precision is also there, from the lowest frequencies to the treble.
Measurement of membrane reactivity: square waves at 50 Hz (left) and 500 Hz (right).
Momentum True Wireless distills deep and punchy bass with a marked seat. The slight overweight at around 1.5 to 2 kHz subtly boosts the feeling of presence on the voice, guitar, piano or even the snare drum (more attack, more slamming sound). In this context, the intelligibility of the voice is perfectly guaranteed, in all circumstances. The quality of the soundstage reproduction is also to be emphasized here for intras of this type. The stereo is particularly wide and we easily discriminate the different layers of the sound scene (room effects and other subtle effects are clearly reproduced).
But like their main competitors, these intras narrowly miss the fifth star. In question here, a flickering effect and an imprecision of a hair too pronounced in the treble. This is noticeable on the harmonics of certain sources, notably the cymbals (they have a slightly "brittle" appearance) and more discreetly on the sibilants ("sss" sounds). The source of this phenomenon is a small distortion peak around 5 to 6 kHz, which is certainly not very high (no aggressiveness, no accelerated hearing fatigue), but which still spoils the perfect appreciation of this zone. Unfortunately, the app's EQ doesn't help here.

Conclusion
For a first, Sennheiser signs a great success with its Momentum True Wireless. The balance sheet is certainly not perfect (slight imprecision in the treble, controls that would benefit from being more intuitive, multipoint absent, microphone sensitive to wind), but they are among the best in their category in sound reproduction. They also shine with a robust wireless connection and the feeling of comfort they provide. That said, with its launch price (€ 299), this newcomer will have some difficulty finding a place in the face of stiff competition.

Reviews
These are the ones!
I have tried and returned a lot of headphones in my life and this is the best pair of headphones I've owned, in ear or over ear .. a very good investment to make.
Superb sound quality
These are the best truly wireless earphones on the market. Better than Bose, Sony, nuraphones, and any other company. These German engineers are truly something else when it comes to sound quality. On the other hand, battery life is okay, usually lasts me 4 to 6 hours with max volume. Design and fit are great, fits like a glove and the design is settle and low key, not to flashy. Overall highly recommended buying these. Worth every penny.
Best Sound
I didn't really care about all the bells and whistles. I wanted the best sound. I have hereditary hearing loss that blocks out a lot of the mid-range sounds. I compared Apple earbuds, Sony and these. These most definitely have the best sound. They also fit much better than the Sony and Apple. Really happy with them.
Connectivity Issue
These headphones sound really good but there is a major issue with the connectivity. They will not reconnect every time you take them out of the case. BIG problem for $ 300 headphones.
Great Sound, Mild Disomfort
Amazing sound. After trying these, Klipsch T5, and Master & Dynamic MW07 wireless earphones, Sennheiser was the clear winner when it came to sound quality. Making sure you have the right size ear tips is key when it comes to sound. A tight fit is is required for sound isolation and powerful bass. Try on all sizes before settling for one, don't just stick with the default mediums that come pre-installed.
Comfort can be an issue. There is a sharp ridge on the back that sits flush against the ear. It should be rounded. It sits there like a dull blade, and is more noticeable when you press the side button to control your music. Master & Dynamic comes with an optional silicon sleeve that provides an excellent cushion and added grip. Sennheiser could really benefit from this addition.
Connectivity is the last thing that needs help. If your phone has paired to anything else (because, Google Home, Alexa, stereo, anything bluetooth) since the last time you used your earphones, they will not automatically pair to your phone again. You must put them back into pairing mode and go through the processing of pairing them to your phone.
However annoying the connectivity issue is, it's not that big of a deal and shouldn't be a deal breaker when considering how great these sound. The only major flaw is the comfort. I still consider these a great buy. And considering how much you'll use them, they're worth the money.
