The H550 paired up very easily with my Motorola e815 but it was all downhill after that. It would not understand any of the voice commands and insisted upon asking if I wanted to send a text message. My Motorola H850 is far superior though I've had some problem with being heard on the other end 2which is why I tried the H550.
