Plantronics Voyager B4210 UC Wireless Mono Headset, Black

The Plantronics Voyager B4210 UC is a wireless mono headset designed for professional use in office environments. Its on-ear design allows the user to remain aware of their surroundings while handling calls. The headset connects to PCs, Macs, and mobile devices using Bluetooth 4.1 and an included USB-C dongle, which provides a wireless operational range of up to 30 meters. This model is optimized for Unified Communications platforms, intended to integrate with business communication software.

Voice clarity is the primary focus, with a flexible boom arm that houses a unidirectional, noise-canceling microphone to isolate the speaker's voice from ambient sound. Audio is delivered through a 32 mm driver, and the system includes SoundGuard DIGITAL processing to protect against sudden loud noises. The internal battery supplies up to 12 hours of talk time and recharges in approximately 1.5 hours. Users can manage calls and adjust volume using the on-device buttons located on the earcup.
