Summary: I bought these for their noice cancelling abilities as I travel on aircraft a lot. The noise cancelling is beter than a standard airline issue headphone but not brilliant. They are very comforable and light to wear and you wont have sore ears in you fall asleep with them on!
Summary: These headphones are great. Sounds come across well and are accurately reproduced. The noise cancelling is a real must have in noisy environments. Bluetooth is easy to set up and rarely drops out.
Summary: I have been a very satisfied user the MM 450-X headphones for several years. I wanted to try these around-ear headphones as my only complaint with the 450-X was that after many hours of use, there was some fatigue on my ears. In terms of comfort, these headphones are great.
At the price paid, they were value, but maybe not quite living up to the top-of-the-range billing you expected from Sennheiser

Summary: When i saw these half price I decided to go for them. They still seem overpriced to me tbh, but at half price I can live with that. The noise cancellation is OK, but being active I think it needs louder noises than hums and rumbles.
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: It has taken me some time to come to a conclusion on the Sennheiser MM550X. They are a bit of a Curates egg, good in parts, as they can be Bluetooth, hard-wired, have Noise Cancelling, Surround sound and are extremely portable.
Summary: Bought for my husbands birthday and as a traveller thought these would be perfect as he loves to listen to music and watch movies whilst travelling! Only negative i would say is he said they are not as loud as when they are directly plugged in using the wire. Aprat from that fab item.
