Poly EncorePro EP545 Convertible Headset | USB-A | USB-C – 783R4AA

Product Overview

The Poly EncorePro EP545 (783R4AA) is a versatile convertible headset designed for contact center professionals and hybrid workers who need flexibility in how they wear their headset. Featuring three wearing styles—over-the-head, over-the-ear, and behind-the-neck—this mono headset adapts to individual preferences while delivering consistent call quality throughout demanding workdays.

Built with both USB-A and USB-C connectors on a single cable, the EP545 connects seamlessly to any PC regardless of port availability. The inline control module features clearly-displayed, recessed buttons for call answer, hold, and volume control—preventing accidental activation during calls. SoundGuard technology protects against acoustic shock by limiting sounds below 118 dBA, while the noise-canceling microphone with 290° rotation ensures your voice comes through clearly in any environment.

The EncorePro EP545 is built for UC applications and softphones from Avaya, Cisco, Genesys, and other major platforms. Weighing just 22-32 grams depending on wearing style, this headset delivers all-day comfort with soft, replaceable ear cushions and a lightweight design that reduces fatigue during extended call sessions.
