Poly EncorePro HW540D Convertible Digital NC Headset, Black

The Poly EncorePro HW540D is a digital headset engineered for professional use in office and call center environments. Its primary feature is a convertible design that offers three distinct wearing styles—over-the-head, over-the-ear, and behind-the-neck—allowing users to select their preferred fit. The headset connects via a wired USB interface, which provides a stable link and consistent digital audio for unified communications platforms. Its 30 mm drivers are tuned specifically for voice clarity, with a frequency response of 150 to 6800 Hz.

Voice transmission is handled by a noise-canceling boom microphone with a unidirectional pickup pattern, designed to isolate the speaker's voice from ambient office sounds. Constructed with aluminum components, the unit has a low weight of 32 grams, making it suitable for extended wear. Integrated Digital Signal Processing (DSP) actively refines audio signals for improved call quality. The headset also features a detachable Quick Disconnect cable, which enhances durability and allows users to move away from their workstation without disconnecting the call.
