Summary: Not really noise cancelling and even less 'portable' as the only reliable thing about them is their breakage rate when removed from a room. I have tried to get on with these headphones as I have many other Sennheiser products. My back-up 'phones are Zik, but their delay makes them almost unusable.
Summary: Desperately wanted just a little bit more volume on these. Found myself almost in tears having debated for ages about headphones and finally got these. The volume isn't there and all I want is goosebumps. Give me goosebumps! I can't get them with this volume.
they work rather well and certainly one of the best bluetooth wireless headsets on the market

Summary: they work rather well and certainly one of the best bluetooth wireless headsets on the market. however volume is an issue as have mentioned prior, about the only thing letting this product down, even with the built in amp active it still can have issues.
Summary: The side buttons are hard to find when the phones are on your head. They are not in any intuitive place. The quality from the phones themselves is disappointingly dire. The noise cancelling is OK.
Summary: Got these a few days ago. Not happy. Would not turn on .tried a few times before success.then it turned itself off. This was after 3 hour charge Volume not very good. Have also tried the mm450 x travel but also hot happy, the battery kept pulling out when I took charge cable out.
Summary: Have had a number of Sennheiser headphones and have liked them all. Got some Amazon vouchers for my birthday and decided to treat myself. I do a lot of flying and these seemed to fit the bill. Having unpacked them I found them easy to set up band they were reasonably comfortable on the ear.
