Product arrived on time and works as advertised. I got this headset for listening to music on the Pearl 8100. Works great. Receiving a phone call while listening to music is a no-brainer: just push the answer putton and the music is put on hold while the call is handled. I'm loving it so far.FYI. For phone calls only, I just picked up the Jawbone bluetooth earpiece at a Cingular store, and it also seems to work as advertised. Very nice noise cancelling.
