Poly 85Q32AA is a 3 m adapter cable that connects a headset with a Quick Disconnect (QD) connector to a device with a 2.5 mm jack. It is listed for Poly EncorePro 300, 500 and 700 series headsets.
The device end has a 4-pole 2.5 mm stereo plug, while the headset end has a QD connector. Its coiled shape leaves cable length for movement around a workstation while keeping the lead in a spiral.
Use it to connect a compatible EncorePro headset to equipment with a 2.5 mm connection, such as a phone or desk adapter. It links the headset’s QD connector to the device-side jack.
