Poly EncorePro HW520 Stereo Headset | QD – 783P6AA#ABA

Product Overview

The Poly EncorePro HW520 (783P6AA#ABA) is a professional-grade binaural headset engineered for demanding call center and customer service environments. Covering both ears, this over-the-head design provides greater focus and concentration by blocking background noise, making it ideal for telephone-intensive users in busy office settings. The flexible noise-canceling microphone features visual and tactile positioning guides that provide immediate physical and audible feedback, ensuring optimal mic placement for crystal-clear conversations.

Built for all-day comfort and durability, the HW520 weighs just 74 grams thanks to laser-welded aircraft-grade aluminum construction that reduces weight by over 15% compared to previous generations. Metal joints deliver exceptional reliability for long-lasting performance, while soft ear cushions ensure comfort during extended 8+ hour shifts. Wideband audio up to 6,800 Hz delivers richer, clearer conversations and reduces listening fatigue.

The Quick Disconnect (QD) connector provides walk-away convenience and universal compatibility with all Poly QD cables, amplifiers, and USB audio processors. SoundGuard technology protects against acoustic shock by limiting sounds to below 118 dBA, helping organizations meet OSHA and Noise at Work regulations. Telecoil hearing aid compatibility ensures accessibility for all users.
