This adaptor converts the standard 3.5mm smartphone headset plug to an RJ9, RJ10, or RJ22 handset plug, allowing you to use your favorite smartphone headset with your newer VoIP office phones. The adapter outputs binaural sound for stereo headsets, meaning you will hear sound out of both ears. The adapter cable is approximately five inches long.

COMPATIBILITY LIST
*For optimal use, please plug into the headset jack on your phone. The handset jack usually causes audio distortion
This list is not all inclusive. Please look up the specifications on your specific phone to see if it has a RJ9, RJ10, or RJ22 headset jack. If the Headset Buddy doesn't work with a model on this list we will be happy to refund 100% of your purchase plus pay for return shipping.
