Controls are a little confusing. The ANC and music clarity/bass is slightly better than Sony's chn-700n. The ear cups are smaller than the sony chn-700n but has thicker padding.

I have tested Bose headphones for$350 and these are very nearly as good. I sit next to the help desk and it nearly eliminates the noise. I'd buy them again!

I love it! It's been five years since I have had it. It wasn't overused. It is still in use. I didn't have time to order ear pods Positive The battery still works great Audio quality didn't change The plastics didn't fade or cracked Buttons works Connecting easily The quick connection between devices Negative Ear Pods last for four years Noise cancellation seems over when it's on. Its have high pitch noise. Overall, it lasted long five years. The noise cancellation probably ended with a drop. I recommend it to everybody. I will buy it in the future Sennheiser products.

These beat out 2 other pairs (See below) that I tried before finding them. They fit well (I have a small head as a female) but do start to bother me after a full 8 hour day of conference calls. The sound is crisp and there is a great volume range. I am severely hearing impaired but still have room at the top end to turn up the volume if needed. The noise canceling could be a bit better, and a bass boost would be nice, but was willing to sacrifice that for the crispness. I use these primarily for business conference calls so that I can hear better. They are not Bose, but really do come close - and for $89 verses $299, it was a no-brainer. Came with a soft pouch case - would have been nice if they came with a hard shell case. Control buttons are not very intuitive, but not complicated once you read the instructions. Would be 5 star if the ear foams were softer and better at noise canceling and they came packaged with a hard shell case. Tried and returned Skull Candy Model S6CRW-K591 ($89) - noise canceling wasn’t great and they didn’t fit well. Ran really small, even for my tiny size 6 head. (I’m female). Not comfortable and sound was not clear. Maxed out the volume range and still had a difficult time understanding conversation. Bass boost was too much, but without it everything was tinny sounding. They didn’t last 10 minutes before being packed back up for return. Did have a nice hard shell case. Also tried Anker Soundcore Life 2 Active Noise Cancelling Wireless Bluetooth Headphones with Case. ($69) They were super comfortable and the noise canceling was very good. But the sound wasn’t crisp and they ran a bit large. They kept falling off. Volume range and bass were decent. Biggest issue was that the blue tooth connection was continually dropping. Might have kept these if they would have stayed on my head, stayed connected and I hadn’t compared the sound quality to the Sennheiser. Nice-hard shell case.

Overall, these headphones are great! They are comfortable to wear for long periods of time. Volume is good and it's nothing over bearing. I enjoy the balance sound that these have. I don't find them to be overwhelming in the low end or high end which helps me with some audio production projects that I have going on. I do wish that the aux cable would be a standard 3.5mm jack instead of the 2.5 and maybe a thicker cable but time will tell if that cable will last a while or not. I do appreciate having buttons dedicated to volume up and down and back and forward for song selection. The bluetooth was easy to setup on my devices which wasn't anything too time consuming. My overall experience with these have been pretty great so far. I would recommend these to someone looking for a great set of wireless headphones that are in middle of the road for price range and upgrading to that next tier of headphones.
