Headset Buddy Female 3.5mm Smartphone Headset to Male RJ9 Telephone Plug Adapter (PH35-RJ9a)

*Works best when paired with an amplifier

**For optimal use, please plug into the headset jack on your phone. The handset jack usually causes audio distortion.

This adaptor converts the standard 3.5mm smartphone plug to an Aastra RJ9, RJ10, or RJ22 handset plug, allowing you to use your favorite smartphone headset with your Aastra office phone. 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.
