Headset Answers > Which Leitner Quick Disconnect Should I Use?*

Great question!

Here is a QUICK breakdown of LEITNER QD Cords!

LEITNER QUICK DISCONNECT Cord:

This cord plugs into most telephone RJ9 headset jacks. If your phone has a Headset Button, this cord usually plugs right now (see Avaya phones listed below for exceptions)

For folks that need amps, you can use this cord to connect to the the Headsets.com or Sennheiser amp.

For Plantronics and Jabra amps, this cord is not needed! LEITNER corded headsets can plug into the cord that comes with the amp for these 2 brands!

Compat for this cord is all over the map! If it’s not listed in our Compat Guide, do some testing for their best sound quality. Compat switches are located on the cord that is attached to the headset. (Avaya quick disconnect cord looks slightly different).
