The Poly DA85 (HP part number 786C7AA, Poly 218267-01) is a USB to Quick Disconnect (QD) digital audio adapter that connects Poly and Plantronics wired QD headsets to a computer for softphone and contact-centre calls. It includes an inline processor with answer/end, volume and mute buttons, status lights and SoundGuard Digital acoustic protection, on a 1.3 m cable.
Compatibility Note: The DA85 works with Poly/Plantronics Quick Disconnect (QD) headsets such as the EncorePro 500 series; it does not accept 3.5 mm or USB headsets. Standard version — for a dedicated Microsoft Teams button choose the DA85-M (HP 786C8AA).

Frequently Asked Questions

Which headsets work with the Poly DA85?
Any Poly or Plantronics wired headset with a Quick Disconnect (QD) connector, including older QD models such as the EncorePro 520, 530 and 540.
What is the difference between the DA85 and the DA85-M?
The DA85 (786C7AA) has standard call controls for any softphone. The DA85-M (786C8AA) adds a dedicated Microsoft Teams button and Teams certification.
Does the DA85 replace the DA80?
Yes. Poly launched the DA85 in 2021 as the successor to the DA80, with inline controls, SoundGuard Digital and firmware updates through Poly Lens.
Singular Expert Insight
For contact centres already running Poly QD headsets, the DA85 is the easiest way to move desks from desk phones to softphones: plug in the USB end and keep the existing headsets. If you do not need inline controls, the passive DA75 is simpler; for Teams-first deployments, the DA85-M adds the Teams button.
✓ Buy it if you have Poly/Plantronics QD headsets and need USB softphone connectivity with call controls.
✕ Skip it if your headset uses a 3.5 mm jack or USB directly — it has no QD connector.
→ Also consider Poly DA85-M (HP 786C8AA) with Microsoft Teams button, or DA75 without controls.
