Built for call centers, help desks, and busy office teams, the Poly EncorePro HW510 delivers clear, reliable calls throughout the working day. Its monaural, over-the-head design covers one ear while leaving the other open, so users stay aware of their surroundings while staying focused on the caller. Wideband audio (up to 6,800 Hz) delivers richer, clearer conversations, while the noise-canceling boom mic — with visual and tactile positioning guides — ensures precise placement and strong voice pickup even in louder office environments. SoundGuard acoustic protection limits sudden loud sounds to below 118 dBA, helping protect hearing and manage daily noise exposure across long shifts. Quick Disconnect (QD) technology lets users unplug and step away without ending the call, while durable metal joints and laser-welded construction are engineered for long-term reliability in demanding, high-usage environments. At just 52g, the soft ear cushion and adjustable headband keep it comfortable for all-day wear.
