- Use your 3.5mm headset with almost any office phone - 8 settings cover most phone models including Cisco
- Combines the PH35-RJ9A of the PH35-RJ9Cisco adapters!
- 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.
- Apple EarPods work on channels 1, 6 & 7
This amazing adapter switch converts the standard 3.5mm 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 (13) inches long.
Q: How do I know what switch setting is right for my phone?
Q: My phone is not listed on your compatibility list. Will it work with your adapter switch?
*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 will refund 100% of your purchase plus pay for return shipping.
**For optimal use, please plug into the headset jack on your phone. The handset jack usually causes audio distortion
