I was trying to listen to my iPod touch with two non-Bluetooth Sennheiser headsets (an IE 60 headset, a PXC 480 headset) and an Apple non-Bluetooth headset headset. Everything works when the iPod is not in your pocket. Only the Apple headset works when the iPod is in the case. That means I have to either use an OK Sony Bluetooth headset or take the iPod out of the case if I want to improve the sound quality.
