I use a bose QC3 headphone with a really expensive bluetooth kit. I tried listening to music on my N95.
You'd expect something from bose would give a good sound quality. I'm not very impressed with it. The difference in sound quality when I use the wires is quite significant. If you're not fussy about sound quality like me then listening to music with bluetooth then you won't be dissapointed.
I like the auto pairing function of this thing though.
