When using bluetooth, the music is compressed and sent over to your A2DP bluetooth device. I've had horrible luck with mine (The music had no bass at all). Think I'm going to have to settle for a wired approach :/
This is the only downside of our sound systems. When I plugged the AUX in to the iPhone headphone jack, it sounded like ass. No bass and it sounded like a radio station out of tune.
