I have the Moto Ht820 from my Moto Q days and it works great with my 8830. Since pairing I have listened to stereo music as well as received calls and it seems to do so alot better then I imagined.
One thing I should mention, I upgraded to the latest software before trying this, so it may not work on all versions??
I'm on version 4.2.2.123 with Bell Canada (8830) and have paired it with the sony street style headphones (DR-BT21G). The sound is awesome. Also have the ability to skip to the next song, ect. Great battery life on both devices and I can take calls and use voice dialing using the same head phones. Stay away from the BlueAnt X5 because it sounds terrible and has poor build quality.
