I use a BH-800 with my E70. I would guess their bluetooth implementations are comparable. I'm relatively happy with the pairing. I occaisonally lose connection. It immediately recovers, but resets the volume to the lowest setting. And sometimes I get more static than I would like. This is my first BT headset, so I don't have a lot to compare it against, but I decided it was fine for my main use: talking in the car with the phone on the seat next to me.
