While i was buying my Universal Dock, i also bought the bluetooth headset.
The price is a little steep, however the ease of use is pretty impeccable. The headset can be paired with your phone just by plugging it in using the cable. The single button is used for everything, as usual for bluetooth headsets.
The quality is reasonable, slightly static on the earpiece, but no worse than i’ve heard from bluetooth headsets before. I don’t, of course, know the microphone quality, but everyone seems to have been able to understand me properly.
I would say, that if you’re willing to spend the extra money, then it complements any iPhone.
