Poly EncorePro HW520V Stereo Headset | QD | Voice Tube – 783P8AA#ABA

Product Overview

The Poly EncorePro HW520V (783P8AA#ABA) is a professional-grade binaural headset designed for telephone-intensive environments including call centers, help desks, and customer service organizations. Featuring a lightweight over-the-head design at just 72 grams, this headset delivers all-day comfort with soft ear cushions and an adjustable headband that ensures a perfect fit during extended shifts.

The HW520V features a voice tube microphone design that provides clear voice delivery without distraction. The detachable voice tube is both clear and easy to clean or replace, making maintenance simple. Wideband audio support up to 6,800 Hz delivers richer, clearer conversations while reducing listening fatigue. SoundGuard technology protects users from acoustic shock by limiting sounds above 118 dBA, meeting OSHA and Noise at Work regulations.

Built for durability in demanding contact center environments, the HW520V features laser-welded construction and metal joints engineered for reliability. The Quick Disconnect (QD) connector provides walkaway convenience and compatibility with all Poly USB adapters, desk phone audio processors, and direct connect cables. Visual and tactile positioning guides ensure precise microphone placement for optimal voice clarity on every call.
