As usual, sennheiser did once again. In terms of sound picture, it is superb. High and mid ranges are clear and crisp. The bases are deep and fat but without loosing resolution. I find them a bit lacking in the ANC department compared to Bose q45. I know it by design that sennheiser left the ambient sourounding sound to sip through for safety issues, and I wish they would have just went for better passive sound proofing and ANC as to be able to completely shut out the sourounding if one wants to (like that crying baby on a long flight). But for all the other cases which is 90% of the time they have nailed it. I just love how the sound stage soround me and envelope me with my favorite music pieces. They really compliment what ever I play through them.

Pre-review note: I've owned the Momentum 2's and Momentum 3's in the past, so this is not my first experience with this line of headphones. I bought the Momentum 4's maybe a year ago or so (give or take, I don't exactly remember) and I could not be happier with my purchase. These headphones blew my expectations put of the water completely. The audio quality all around is superb, with crisp sound, and deep and powerful bass without anything becoming muffled or overpowering. The noise cancelation is the best it's ever been in the Momentum line so far as well. The 2 biggest leaps of improvement with these headphones over the previous Momentum headphones though are the absolute comfort while wearing them, and the battery life. I can wear these headphones literally all day from waking up to falling asleep and not feel any pain or discomfort at all (which says something because my head tends to be sensitive to headphone and earbud strain). I've never had any personal audio device in my life where that's been the case. As for the battery life, it's very impressive. These headphones can potentially last you a week without needing to charge them. Once again, I've never experienced a device with such an efficient battery in my life. There's no end to the positives I could give about these headphones, so I'll just give whatever cons I can muster up for the rest of the review to save us some time. Con 1, the touch controls are not my personal preference, I prefer physical controls like on the Momentum 3, but it's not a big deal to me, especially since you can use the app to turn off the touch controls if you don't want them on for fear of accidental touches. Con 2, the mic on the headphones isn't the best quality, but this is really just an unfair nitpick since this isn't meant to be something like a gaming headset (if anything it's great that it has a mic in the first place). Con 3, if you can call it one, is that the visual identity has somewhat been lost from the previous Momentum headphones. The older ones looked more visually interesting, although I really don't care personally. I remember the Momentum 3's also being made with a lot of metal components which gave it incredible durability. I really can't think of any more negatives. In conclusion, if you're on the fence about these headphones, they're definitely a great pick and I can't recommend them enough. If the price is a little steep for you, I've seen several decent sales for these. If you decide to get these, I hope you enjoy them as much as I have been and will continue to.

Sounds great, but feels not so comfortable, as I expected. Single tap control is not handful, it often trigger pause\play when I just want to correct the heaphones possition on my head. Put on\off sensor works only for right ear, which I only drop off to temporary listen somebody outside, and when I put it back music is not always start play again (ancident 1 tap + sensor reaction = play+stop?). I don't know, but it's annoying.

I bought two years ago, and the sound and duration of battery are good, very good. They have a new characteristic: Very strong to crash over floor... I thouhg that my M4 I lost it, but was a surprise that continuos working well!!!

Bought this after trying my friend's Momentum 4 on... I am in love with this! Dynamic sound with accurate deep bass and crisp details! Super comfortable too!

I love them. You hear sounds and pitches on songs that I have never heard. These are songs I have listen to for years. Great price, battery life and style. I only wish there was more high in wireless options. Sounds concealing is satisfactory.

I had wireless B&W headphones which broke after a couple of weeks of use. The foam in the earcups were visible because the flimsy cover was getting separated by the earcup and there was no way to put it back. So I decided to go with a Sennheiser (mi wired headphone is Sennheiser) and noy only is better built than the B&W but it sounds better and easier to set up. Very happy with my new wireless headphone.

The headphones are fantastic, however there is an audio imbalance issue where the right earphone is punchier than the left earphone which throws me off a little, even after using a EQ Balancer to adjust the audio to be a bit more left leaning, the issue still persists slighty.

The sound quality was great, which is why I chose these over a comparable Bose model. I thought the extra price would be worth it. I'm not even 3 months in to having these and they stopped working. I wish I had listened to the other reviews and reddit threads. While they do have a 2 year warranty, since this is a known, recurring, issue, it seems like they will only be good for 2 years. And because the warranty process is lengthy, I will be without headphones for about a month. Buyer's remorse.

Over the past decade I've owned headphones from Bose, Sony and now Sennheiser. The Momentum 4 is the replacement for Sony MX-4. The sound quality of the Momentum 4 is much better than Sony. It's very natural. Making phone calls under the windy conditions is much easier since it suppresses the wind effect very effectively. The only complaint I have is with the ANC which isn't anywhere near the effectiveness of the Sony.
