I just purchased the new inifinxx ap23 adapter to go with a pair of Sony DR-BT22 headphones (bluetooth headset). From everything I have read this should work for my iphone (2nd gen). But no music seems to play. Has anyone else tried this new adapter or these headphones? The adapter was about $65 and headphones close to $100, so if it isn't going to work, time to return! Thanks.
