Works well with many/most phones. I've tried it with several different brands of cell phones and it works well with all of the ones I've tried (Motorola, Samsung, LG). Very quiet with the noise cancellation - there have been times when it was so quiet I thought I'd been disconnected LOL It's also quite comfortable, even with sunglasses and a hat on. This is the best bluetooth headset I've had so far, and I've tried quite a few. As with most headsets, you might have to play with the volume on both the phone and the headset to get the right volume so you can hear but not have an echo.Highly recommend. I've had mine for a couple years now, and still love it!
