Universal connectivity and future‑proofing
With a dual USB‑A/USB‑C connector on one cable, you can connect the adapter to any computer without dongles. The POLY DA series is compatible with new and legacy Poly headsets and accessories, protecting your investment and simplifying company deployment.

Smart audio for clear calls
The intelligent headset recognition feature dynamically optimizes audio for the specific Poly model so calls are clear and natural. SoundGuard DIGITAL monitors daily noise exposure, limits peaks (G616), and the Anti‑startle feature protects against sudden volume spikes.

Effortless control and integration
With a single click, you can instantly mute all audio and visual transmission during a call or video conference. Support for the Quick Disconnect (QD) interface lets you step away from your desk quickly and reconnect with ease. The adapter is optimized for leading communications platforms, which IT admins will appreciate.
