This is Bluetooth Wireless Headset. Freedom to exercise, move around and commute without wires to tangle or hold you back.

Other Thoughts:THIS OP DOESNT SUPPORT STEREO BLUETOOTH AND IT'S A LITTLE TRICKY TO MAKE IT WORK.-some time in google will give the how-to) and a samsung cell phone with a wide range and the good sound with no drops.
<br/>I strongly recommend it.
