*For optimal use, please plug into the headset jack on your phone.
This amazing adapter switch converts any 3.5mm headset to a RJ9/RJ10/RJ22 handset plug, allowing you to use your favorite headphones with your Cisco, Aastra, and etc. VoIP 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.
COMPATIBILITY
*This list is not all inclusive. Please look up the specifications on your specific phone to see if it has a RJ9, 10 or 22 handset jack. If your phone is on this list and the Headset Buddy doesn't work then we'll refund 100% of your purchase.
