I'm looking to find some sort of way to listen to stereo music on my BB 8800, but so far have had no luck at finding a compatible headphone. At radio shack they had mini-plug adapters which had four prongs, but they wouldn't work since it looks like the BB only takes a 3 prong connector. Does anybody have any recommendation on adapters / headphones?

Does the USB port work to output audio also? I saw a headset at RS which was for USB, not sure if it was compatible.
