I use it with two cell phones and it works great. It will drop out every once in a while but it's easy to reconnect. I have tried to use it as advertize with my computer (listening to music) and cell phone but it will not stay connected for more than a few minutes at best. Also the audio quality is fine for voice but has a lot to be desired for music. If you are wanting to use it with computer and cell I would look elsewhere but for two cell phones I would highly recomend it.
