Ask Engadget: Best solution for Bluetooth stereo audio?

Look out! You've just stumbled upon this week's episode of Ask Engadget, and we've got a real brain burner on our hands this evening. Before you dig in, though, feel free to blast your own question in to ask at engadget dawt com.

I recently got a new music-oriented phone (Nokia 5800 XpressMusic) with Bluetooth stereo audio (A2DP) and am trying to get some opinions on what might be the best solution out there for me. It seems to me like I have 3 options as far as general solution types: self contained Bluetooth headphones, such as the Motorola S9; Bluetooth receivers with headphone jacks, such as the SonyEricsson HBH-DS220; or transmitter / receiver pairs. My specific needs are that it supports remote control (AVRCP), has good sound, is under $100, and if the unit can bind to multiple devices that would be great. The ultimate item would somehow work with my phone as well as my PSP, but that's probably a pipe dream. Thanks!

So, wireless audio partakers -- what say you? Got any great tips? Got any horror stories? Either way, spill it below.
