Replacement cord for the Plantronics M10, M12, M22 and MX10.

Also connects Plantronics H series headsets directly to the Cisco 79XX model phones. It is recommended that your phone be using power over ethernet, or the grounded Cisco CP-PWR-CUBE3= power supply, to ensure interference free operation.

Note: Not suitable for use with non-Plantronics headsets. For most headset applications, we recommend the GN/Jabra 1200 QD to RJ-9 Headset Smart Cord.
