This functional adapter converts your HTC built-in 11 pin jack into a 3.5 mm (female) headphone that will allow you to use any standard 3.5 mm headphone of your choice.
Lightweight and trendy, this hands free adapter allows you to listen to MP3's, be alerted by incoming calls, answer and hang up calls with a one-touch button, and adjust the loudness of music and calls with the built-in volume control.
Enjoy tangle free cords and the ability to adjust the cable length to your liking by simply pulling on both ends of the cable, which will retract the cable neatly and quickly back into the housing.
