This product does exactly what it says it will. When I bought it, I didn't realize that it also doubles as a hands free headset for calls, I bought it simply to listen to music on my MP3 player phone. That's a nice feature, now I can answer calls while I'm listening to music without taking my headset off, or switching to blue tooth. My one beef is that you have to use the "pop port" and that it doesn't have a standard headphone jack, but that is an issue with the phone and not the headset, so the headset gets all 5 stars.
