Poly EncorePro EP320 Stereo Headset | QD – 77T26AA

Product Overview

The Poly EncorePro EP320 (77T26AA) is a professional-grade stereo headset designed for contact centers and customer service environments. Featuring a 4mm unidirectional noise-canceling microphone on a flexible boom, this headset ensures your voice comes through clearly while blocking out background noise from busy office environments. The dual-ear stereo design helps agents focus by reducing ambient distractions, leading to better customer interactions and improved productivity.

Built for all-day comfort, the EncorePro 320 features soft, replaceable foam ear cushions and a lightweight design that won't cause fatigue during extended shifts. The fold-flat earpieces make storage convenient, while the Quick Disconnect (QD) connector—tested to over 30,000 cycles—provides proven durability and flexibility for hot-desking environments. Voice-optimized frequency response dynamically switches between telecom mode (200Hz-6.8kHz) and multimedia mode (50Hz-8kHz) for clearer, more accurate conversations.

SoundGuard acoustic limiting technology protects agents' hearing by limiting sounds to below 118 dBA, helping organizations meet workplace noise regulations. The QD interface connects to desk phones via Poly audio processors or direct connect cables (sold separately), making it compatible with virtually any enterprise phone system.
