Description
The Poly A10-12 QD Headset Adapter Cable (85S26AA) connects Poly H-Series Quick-Disconnect headsets to desk phones that have a dedicated 4-conductor headset port — the type found on many business phones designed to accept a headset directly without a separate amplifier. This cable is the right choice when the phone has a dedicated headset jack (as opposed to the handset RJ9 port), giving you a clean, direct connection without additional hardware.
Key Features
- Dedicated Headset Port Connection: Designed for phones with a built-in 4-conductor headset jack — plugs in directly without an amplifier or adapter box.
- Quick-Disconnect End: QD connector allows instant headset detachment for walkaway convenience without ending the call.
- H-Series Compatible: Works with the full range of Poly H-Series QD headsets.
