I haven't found a good resource online for this so I figured I'd start a thread with information I've found. As we all know the new 3.0 version of the iPhone OS supports stereo bluetooth, specifically the A2DP profile. This will work on both the iPhone 3G and iPhone 3G S, but not on the original iPhone. Unfortunately there does not seem to be support for the AVRCP profile, which allows you to skip tracks from a bluetooth device. Hopefully this will be added in the future. Also there is a bug with the volume controls when paired with stereo bluetooth headphones. The iPhone assumes that you will control volume via the headphones, but not all headphones have volume controls, for example the Sony HBH-IS800Z's are a beautiful simple set of stereo bluetooth headphones, but the lack of volume controls on the headphones make them very difficult to use with an iPhone. At this point I've ordered the Jabra BT3030, which has the benefit of letting you plug in any headphones you want, I'll update this post with a review of those headphones with my iPhone 3G S when I get them. Please add any information and experiences you might have had with Bluetooth stereo headphones and your iPhone. If I've got anything wrong above please also correct it.
