that you can speak into the microphone for taking calls hands-free, once the

headset is fastened to your clothes.

If you need to adjust the clip, remove the clip and reposition it on the headset cable.

Use the clip to stop your headphones and remote from moving around. This makes the

headset more comfortable to use.
