Poly Voyager 4210 Office Mono Wireless Headset B4210-O-A
The Poly Voyager 4210 Office is a mono Bluetooth wireless headset designed for professionals who communicate across desk phones, computers and mobile devices. Its single-ear design keeps one ear open to the surrounding workspace, while dual-microphone noise cancellation helps your voice remain clear during calls.
Freedom to Move Around the Office
Class 1 Bluetooth technology provides an Office-model roaming range of up to 91 metres under line-of-sight conditions. This gives you the flexibility to move away from your desk while remaining connected, whether you are retrieving documents, speaking with a colleague or completing another task.
Clearer Professional Conversations
A two-microphone system uses one unidirectional microphone and one directional MEMS microphone to reduce nearby background noise. The headset is optimised for telecommunications as well as music and other media, making it suitable for calls and everyday workplace listening.
Connect Across Your Working Devices
The Voyager 4210 Office is designed for use with a desk phone, computer and Bluetooth-enabled mobile device. Its Office base provides a central connection point, while built-in call controls place answering, ending, muting and volume adjustment within easy reach.
Comfortable Mono Wearing Style
The lightweight 110 g mono design lets you remain aware of colleagues and activity around you. A padded headband and cushioned on-ear speaker support comfortable use throughout the working day, while the microphone boom can be positioned for left- or right-side wear.
Useful Alerts and Hearing Protection
Enhanced voice alerts provide information about remaining talk time, mute status and connection status. Poly SoundGuard DIGITAL helps support listening comfort through sound levelling and acoustic limiting for sounds above 118 dBA.
