New C860 Headsets
A new C860 “Type 2” (78-8117-3964-4) headset replaced the original C860 “Plantronics” (78-8095-
0598-1) headset in March 2000. The new Type 2 headsets have a high-resin polyurethane cable, which is
much more resistant to heat and oil/grease found in the fast food environment. Other differences between
the two are the Plantronics had a swivel earpiece and a flat steel band; the Type 2 has a fixed earpiece and
a black plastic-covered round band. The Type 2 headsets use a new ear pad. The original Plantronics ear
pads 78-8069-2667-7 are no longer stocked but the new Type 2 ear pads will fit.
Ear pads for both Plantronics and Type 2 (78-8117-3965-1) each, MOQ = 5.
Ear pads for both Plantronics and Type 2 (78-6911-4693-6) 10-pack.
Both headsets use the same microphone windscreen as the C960 headsets 78-6911-4506-0 for a 10-pack.
Stronger C960 Ear Cup Joint
A stronger C960 ear cup joint, (78-8095-0564-3) was introduced in March 2000. The part number has
not changed. All previous ear cup joints have been purged from inventory.
Redesigned Microphone Windscreens
The C960 microphone windscreens (78-6911-4506-0) (10 pack) have been redesigned. They will also fit
C760 headsets, and the “Plantronics” and the “Type 2” models of the C860 headsets. The new
windscreens are larger and fit more tightly. If a customer is still having problems with the windscreen
falling off, a “Scotchmate” tab (hook and loop) (78-6911-4653-2) (35 pack) can be attached to the
microphone base.
Windscreens should be replaced regularly. If a windscreen is torn or missing, dirt or grease can plug the
holes in the microphone case.
Noise Reduction Module
The A121 (external) Noise Reduction Module requires a system with a separate outside microphone.
The A125 (C960 internal) Noise Reduction Module can be configured to use either a separate outside
microphone or a single speaker that is used as a speaker and a microphone.
