About the Poly EncorePro 300 Series
The Poly EncorePro 300 series is an entry-level contact center headset with a flexible noise-canceling boom and SoundGuard hearing protection. It is built for long shifts at a reasonable price.
It comes as the EncorePro 310 (mono) and 320 (stereo), with USB-A, USB-C or Quick Disconnect (QD) connection. QD versions work with Poly QD cables for desk phones and amplifiers, and the QD connector is tested past 30,000 cycles.
Use it for agent seats and shared desks. The EncorePro 500 series adds more durable construction, a Teams button on the 515/525 and USB-A plus USB-C on one cable.

Mono or stereo?
EncorePro 310 is mono; EncorePro 320 is stereo.
