Hi there guys, I'm currently using a pair of Bowers&Wilkins P5's that I love and adore, but everyday of using them the cable snags/gets caught up/tangled and I've started looking at a few pairs of bluetooth headphones as a possible upgrade but have no idea what kind of quality any of them have. So, any recommendations of headphones? I'm not super fussed about noise cancelation, but the audio itself has to be good. I also don't know anything about the quality of Bluetooth audio, what kind of bit rate and audio quality can you achieve? Thanks a lot!
