Device paired - perfect 1st time, music feature - no problem, clarity hearing voice and music - excellent, voice command - works 1st time when answering call. Noise canceling is excellent. People were able to hear me with considerable amount of background noise (even a dog howling). Clarity was much better than the Jabra Freeway that I tried. Note: If you are using a Samsung 3 and cannot get the voice commands to work press "phone" icon on the Samsung 3 then the "Bluetooth" icon, then back out of the menu, if you don't follow this procedure the phone will not activate voice command mode when you press the microphone button on the Motorola Bluetooth. I think this is more of a phone issue than the device.
