I use this headset to listen to my favorite radio station on my smartphone via iheartradio.com and I am amazed at the technology that allows me that luxury in such a small package. The other really great option is that I am able to use just the primary earpiece (and recieve audio; obviously not in stereo) by unplugging the earloop-extension to the other ear and just adding the included 'unwired' earloop. This allows me to hear conversations with people in the room without having to remove one earpiece. And, most importantly, when a call comes in the music stops and is replace by your ringing tone, and all of this in a wireless bluetooth small package!
