I bought this expensive beast because I missed my stereo headset that I had with my XDA, figured Wireless would be even better.

The result is - It connects fine even on a wake up.

Audio for anything OTHER than a phone call is terrible.
And even a phone conversation isn't as clear as I'd like.

BUT - for watching video or listening to music. I simply use the dongle that comes with it. Plug that into the headphone jack.

THEN Everything is Phenomeonal!!!
I have the B&O A8 headphones, and these sound just as nice!
Booming Bass + Crisp High notes.

So if you can handle the extra dongle stuck in your PDA case, then it's a great buy. but at $200 it's not cheap.

Battery life is stated at about 6 hours, but I haven't really measure that.
