Poly Voyager 4310 Bluetooth Mono Headset with BT700 USB-A Dongle

The Poly 76U48AA is a Voyager 4310 Bluetooth mono headset that gives professionals a simple way to sound clear and stay mobile throughout the workday. It connects to your laptop through the included BT700 USB-A dongle and pairs with phones or tablets over Bluetooth, so you can jump between devices without missing a beat.

Bluetooth 5.2 wireless technology and a range of up to 164 feet let you step away from your desk while keeping the conversation going. The headset can stay connected to two devices at once and remembers up to eight, a practical touch for anyone who moves between a computer, a phone, and shared meeting spaces.

Calls stay distraction-free thanks to a dual-microphone array that uses Poly Acoustic Fence noise reduction to remove background chatter. A dynamic mute alert tells you if you start talking while muted, and a dedicated mute button sits right on the earcup for quick access.

A 350 mAh battery supports as much as 24 hours of talk time or 47 hours of listening. When power runs low, a 15-minute quick charge gives roughly 10 hours of additional talk time, ideal for unexpected meetings or a full afternoon of music.

The single-ear, on-ear design keeps one ear open to the room, making it well-suited to home offices, front-desk roles, and hybrid work areas where situational awareness matters. Weighing just 4.3 ounces, it sits comfortably through back-to-back calls, while the Poly Lens app allows easy customization and firmware updates.
