This stereo bluetooth device works well but there are corded ear buds and a chain, so you have things hanging all over you when using it.  I needed a stereo bluetooth device because my Verizon XV6800 won't play audio through the bluetooth, except phone calls, with a mono device.  I chose this one because the controls are easy to see and use.  I've had trouble in the past remembering how to use the controls on devices that sit on my ear.  This one is very easy to use, but I don't like the cables that have to link the device to my ears.  I'll probably switch to something that goes around my head sometime in the future.  However, if you don't mind the cables, this device works well.  I use it primarily to listen to recorded books.  When a call comes in, it switches automatically.  Sound quality is great.
