Sennheiser Momentum 4 Wireless Headphones - Bluetooth Headset for Crystal-Clear Calls with Adaptive Noise Cancellation, 60h Battery Life, Lightweight Folding Design - Black)

The audio quality of these headphones are great right out of the box, didn't even have to tweak with the EQ much just toned down the treble. My only issue is that the Sennheiser app degrades the audio quality for some reason and I did not know this. So at first the audio quality was really bad, it was as if I was listening music through 30 dollar headphones. I tried messing with every setting know to man and nothing seemed fix the bad quality, it was to the point where I had regretted buying the headphones and was thinking of selling them. Finally, I saw someone online mention that deleting the Sennheiser app helps increase audio quality of the headphones. The second I did that the audio quality was so much better and clear. So if you're reading this and are planning to get these headphones, just keep in mind about the app, if the headphones don't sound good just delete the app. I would give this a five star, but the debacle I faced makes me remove a star, otherwise they're great, very comfy and good for long listening sessions.

Superb Sound Quality

I used Sennheiser 350bt for over 5 years, very happy with the headset, plastic components started breaking and I decided to go for Momentum 4. What a disappointment! I use momentum 4 on a PC and the experience is terrible. That touch control panel on the side has a mind of its own, every time I lean in my chair it goes in to mute, Teams and Whatsapp keep crashing whenever I use the headset, the headset switches off randomly and crashes the bluetooth on the PC. Keep loosing Bluetooth connection in areas of the house where 350bt were working without any issue, no Windows application ... Terrible , last pair of Sennheisers that I ever buy, zero stars.

Picked up these headphones and was super excited as i had tried the xm5 and whilst the ANC was great in that headphone Vs the Momentum, the overall sound was muddy. In this the music and sound is much much better, mic/ anc are decent enough for me. The reason why i returned is that Sennheiser needs to address their quality control issues. From the first listen, there was an audible imbalance in the sound. Left ear has more volume Vs right ear, had to adjust the ear balance speaker on my android to make it left bias to counter the imbalance. very annoying. realized when i checked online, it is an issue with a lot of Sennheiser headphones and apparently the latest firmware doesn't help much either. Felt very bad to return these as i LOVED the sound of these headphones apart from the imbalance. Only hope they address their qc issues.

The sound quality is great but the volume is low. Like for example, my airpods pro 2 i listen to them on max 70% normally thats the highest i would go and my normal listen % is abt 50%volume. On these however to get the same level i have to get 80/90%. im always 2/3 clicks away from max volume. Im gonna mess around with it a bit more, but if its gonna be an issue, ill probably return them and go for the bose qc ultra. There is no other issue with it for me, the sound is amazing. I also faced a little imbalance in the left speaker in volume i guess. Not too big of an issue. In the end i returned them, because i don’t wanna have it at 80% volume to have a good listening session. I only go to abt 50% with my airpods. If these had an individual volume for the headphones itself i would have much preferred that like the bose qc ultra’s. The anc was good, but not great which wasn’t an issue to me. Cuz anc isn’t a big issue for me. But the volume in the end was a deal breaker, since i don’t wanna listen at 80% all day. Plus when i go that high there is sound leakage and everyone can hear what im listening to.

It's nice, but I expected more from Sennheiser

As an audiophile, Let me break down my conclusion after using Momentum 4 for about 3 months now. Battery - best in class Comfort - best in class again Bass - amazing Mids - clear Highs - could have been better. App - not interested. ANC - can't compare to Sony or apple. Warranty - 2 years (better than any brand for wireless headphones) Overall happy with the purchase, but expected more powerful amplification with bit of a compromise in battery performance. Also expect more cymbals would be great. If sound quality is your priority, give a listen to Shure aonic 50 gen-2 & momentum 4 in store then choose. Audio is very subjective.

If ur goal is to have the best open sound stage; these are it . The noise cancellation that they have isn’t great and nowhere near the Sonys xm4 xm5 or AirPods Max . But the sound is superior by miles . I’m truly enjoying them currently and I hope they will be reliable...
