I have a pair of Mototrola S305 Bluetooth headphones that I pair up with nearly every device that I own that has Bluetooth. Today I tried pairing it with my Optimus V. While playing my music I notice a hiss in the background. When I plug in a pair of wired headphones there is no hiss. I previously paired it up with my T-Mobile Comet running 2.2 and there is no hiss there. Could it be an issue with 2.2.1 and A2DP? This is nothing that would make me send my Optimus V back, but it is a minor annoyance because I'd have to go back to Wired Headphones. Thanks for your help! UPDATE: I just remembered that it came with wired headphones. I'll just use those for now.
