Purpose and compatibility

The Plantronics 85Q45AA cable connects a 4-pin Quick Disconnect headset to a 6-pin Quick Disconnect port on a desk phone or amplifier. It is designed for office workers who need to use their existing Plantronics headset with equipment that has the larger QD socket.

Upgrade path

This accessory replaces a missing or damaged 4-pin to 6-pin adapter cable. The jump is worth it when a headset with a 4-pin QD plug must be paired with a telephone or base unit that only accepts a 6-pin QD connection, restoring full call-control functionality.

Build integration

The cable sits inline between the headset and the phone or amplifier, requiring no external power or software configuration. It frees up the existing headset for use on different workstations that are fitted with 6-pin QD jacks, extending the useful life of the headset investment.

Questions about this item

Does the 4-pin QD plug fit directly into my Plantronics headset quick-disconnect port?

Yes, the 4-pin QD end connects to compatible Plantronics headsets that use a 4-pin quick-disconnect interface.

How do I connect the 6-pin QD end to my desk phone, and what mistake should I avoid?

Align the 6-pin QD connector with the phone’s handset or headset port and press firmly until it clicks; forcing it upside-down can bend the pins.

Will the cable jacket or connectors need replacement after extended daily use?

The cable is a passive assembly with no moving parts; only physical damage to the jacket or bent connector pins would require a replacement.
