Does the Leitner 2.5mm QD cord work with Plantronics or Jabra headsets

NO, it does not.

The 2.5mm cord for Leitner (Cat# 2356) does not provide sound with Plantronics and Jabra corded headsets.

We did previously have a Plantronics QD cord that will work, but can no longer get it. Sorry!

Thanks!
