Purchased 7 months ago at €105 for music, YouTube, Netflix, and remote teaching.
Initially, their build is very sturdy with good quality plastics and they are quite flexible. The sound is very good with normal bass (it’s normal and doesn’t blow your mind). I am very satisfied with the Active Noise Cancellation and noticed the difference in noisy environments (on the street, for example).
The microphone simply does its job, nothing special. The battery lasts as stated and charging takes 2 hours with a max deviation of +-10 minutes. The plug that connects to the headphone initially seems like it won’t last, as it locks when you snap it onto the headphone, but after a while and quite a few pulls, I saw that it has absolutely no problem.
One observation, the sound seems better to me when I have ANC enabled and at higher volume than without (maybe it’s an illusion since it "lowers" the external noise).
The Sennheiser app is very "empty" but you can get by with the preset options it gives you.
WARNING! The headphones are indeed quite tight and at first I was disappointed because they bothered me a lot and even hurt after short use. HOWEVER, I spent a lot of time and after considerable effort found the position where they don’t bother me at all (note: I have very small ears, with bigger ones the problem might persist), from then on I really started to enjoy them (I even use them for naps).
Another thing I noticed when I was connected via Bluetooth to a PC and in some communication app (e.g. webex, discord, skype) it would preset the headphone microphone and there was feedback from the microphone to the headphones (i.e. I could hear myself as I spoke through my headphones).
Finally, they are very easy to clean and the pads can be replaced with others.

Therefore, I am absolutely satisfied (since I adjusted them properly), but I would expect the price to drop to €120 or less for me to buy them.

Fun fact: the headphones were intended for €200+ but couldn’t compete with others in that category, which is why Sennheiser dropped their price so much.

UPDATE 28-11-22: For some time now, the official Sennheiser app has been upgraded and it has boosted the sound on the headphones! The issue I mentioned with sound feedback (sidetone) in communication apps has also been resolved, as you now have the option to disable or reduce it.

UPDATE 10-7-23: The volume up button lost its "click," but it still works fine.

UPDATE 15-9-23: The seam on the pads opened and their cover quickly disintegrated, losing a bit of sound insulation.

UPDATE 3-11-23: New genuine pads were purchased from a well-known music store chain for €15 and I have to say they are better than the first ones, as they have a larger gap for the ears, making them noticeably more comfortable and easier to wear.

UPDATE 13-10-25: I saw that a major chain store was having a clearance sale and dropped them to €35-40. If mine weren’t still working like new, I’d buy them again!

It's good, but let's not get carried away... They're nice and relatively comfortable for me, even though they put a little pressure on my ears without bothering me too much. I prefer them so they don't fall off.
As for the sound (in mp3 320kbs and flac), I have to say that I come from headphones of similar price (beyerdynamic) but with a jack, without Bluetooth... the difference with these ones that have Bluetooth is HUGE!!! I also installed the Sennheiser app, but nothing... I was forced to get them because of a change in my phone and the lack of a 3.5mm audio jack. With Bluetooth, you gain comfort without a cable, control of the player from the headphones, noise cancelling, but you lose in sound quality... Obviously, you have to pay twice as much because you're paying for Bluetooth, battery, and controller.

EDIT: In the end, the company is not good for consumers as I was told, it's for studios, so only its good and expensive pieces are worth it.
After 5 months, one of the ear cushions came off, even though I always kept them carefully in their case.

    Guys, we're talking about excellent headphones.
    I got them slightly used because their previous owner wanted more bass. He didn't know that the app can do EQ... At this price, it's hard to find better headphones. Amazing features, crystal clear sound, satisfactory noise cancellation, and a battery that actually lasts about 30 hours. I also use them just to isolate noise

    They are quite good quality, but don't expect to have real noise cancellation for this price; it just somewhat reduces the noise around you when you press the button for this function, and nothing more... Otherwise, for the money, the headphones have several features, and the software for the mobile is very useful. Don't buy them if you want noise cancellation

  • Very good headphones, I have had them for about 5 years and I have changed the ear cushions. Their sound is awesome. Disappointed that their application does not support these specific headphones so you can make any adjustments you want. They are totally worth it.

    I bought the headphones a few days ago and I really haven't taken them off my head. I previously had Beats Solo 3, which I bought for £250, and the Sennheizers are on a completely different level for almost half the price. Comments about them being tiring, I think they are a bit exaggerated although it's a subjective matter. Personally, they tired me after 6 consecutive hours of listening. Hit me up

    For their money, they are very good. I have had them for about 3 months now and I can say that I do not regret my money. If you are looking for ANC headphones, there are better options, but these are not bad either. After a long time of use, they hurt my ears because the earcups are too tight, but there is the possibility to change them for more comfort. I recommend them to anyone who gets them, I have tried them from a friend who has changed them and they are much more comfortable (I will do it myself at some point). I have some complaints about the built-in microphone, but it works fine during calls. Overall, they have very good sound, amazing battery life, and very good construction. If you give them some time and get used to them on your head, you can use them for hours.

    Very good design, nice strong sound but tiring after an hour of use. They tighten a lot on the ears and are a bit heavy.
