I have some Sennheiser MM450 bluetooth noise cancelling headphones that I absolutely love. The sound is brilliant and they collapse fairly small for carrying around. The best thing compared to other similar headphones is that if the battery runs out you can plug in the cable and continue wired rather than BT.
