This amazing adapter switch converts the standard 2.5mm headset to a standard RJ9, RJ10, or RJ22 handset plug, allowing you to use your favorite headset with your IP phone. 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. The adapter switch is approximately thirteen inches long.
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 handset jack. If your phone is on this list and the Headset Buddy doesn't work then we'll refund 100% of your purchase plus pay for return shipping.
