I've managed to transfer mp3 files onto my RAZR and purchased the S805 Bluetooth headphones to listen to them. When using the Digital Audio Player to play the songs, I cannot hear them from the headphones. I also get a Failed message on the phone. It's paired correctly and I can make/answer phonecalls from the headphones, but I cannot listen to music. Even if I go to Menu-->Fun&Apps-->Sounds and play a sound, I hear nothing. Any ideas?
