Description

  • Use your headset with almost any office phone - 8 settings cover most phone models including Cisco
  • Combines the PH25-RJ9A of the PH25-RJ9Cisco adapters!
  • Converts 2.5mm plug to single 4P4C RJ9/RJ10 headset plug
  • 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.
  • Works with mono headsets! 
 

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.

FAQs

Q: What is the difference between this adapter switch, the 01-PH25-RJ9A and 01-PH25-RJ9Cisco adapters?
 
A: This PH25-RJ9X adapter switch is our newest Headset Buddy product. It acts as a combination of the PH25-RJ9A and PH25-RJ9Cisco adapters, allowing you to use your 2.5mm Headset with both Cisco and non-Cisco phones! You are able to do this by moving the switch setting selector to the setting that is perfect for the specific office phone you are using.
 
Q: How do I know what switch setting is right for my phone?
 
A: Due to the large number of phone manufacturers and phone models, we are unable to provide a conclusive switch setting list. To find the proper setting for your VOIP office phone, you can do some basic testing. Simply plug the headset into the switch, and the switch into the designated headset jack in your phone. Then, move the switch selector up and down while listening to the quality of sound, until you find the setting that is right for you.
 
Q My phone is not listed on your compatibility list. Will it work with your adapter switch?
 
A: Due to the large number of devices out there, we are not able to test our Headset Buddy products on every phone. If our Headset Buddy does not meet your expectations, please return it within 30 days of purchase so we can refund you in full.
