- Use your headset with almost any office phone - 8 settings cover most phone models
- Combines our PC35-RJ9A and PC35-RJ9Cisco adapters into one universal!
- Convert two 3.5mm plugs to single 4P4C RJ9/RJ10 headset plug. Works with mono and stereo PC headsets!
- Works great with most VOIP phones with a RJ9/Rj10/Rj22 headset jack
- Does not work with RJ11 jack, which is wider than your headset jack (6 positions vs. 4). RJ11 jack is what is in the wall. RJ9, RJ10, RJ22 are what is on your phone handset or headset.
Our PC35-RJ9X switch converts the standard headset 3.5mm mic/audio plugs to a standard RJ9, RJ10, or RJ22 handset plug, allowing you to use your favorite computer/laptop headset with your IP phone. This adapter is designed for use with headsets that have two 3.5 mm. plugs; one for the microphone and one for the headphones/earpiece(s). The switch outputs binaural sound for stereo headsets, meaning you will hear sound out of both ears. Once you plug the headset into our adapter switch, and the adapter into the designated headset jack of your phone, you will need to move the switch setting selector up or down until you get optimal sound for the phone you are using.
This adapter switch cable is approximately 13" (thirteen) inches long.
