I bought these off a UK website for about £20! They work great on my Universal running AKU 3.2. I had to implement a few registry tweaks to stop all the skipping, but after all the tweaking, it now works perfectly.
Sound for music is excellent. Volume is loud. The quality appears a little lower for voice conversations, but on my Universal, it transitions seamlessly most of the time from phone to music modes.
Be prepared for all the little problems that might happen, which probably aren't exclusive to these BT stereo headphones. As you probably already know, most BT stereo headphones don't work flawlessly all the time. Mine's been behaving very well 99% of the time though!
