Poly Voyager 4320 Wireless Headset with BT700 Dongle and Charging Stand 77Z31AA
The Poly Voyager 4320 is a stereo Bluetooth wireless headset designed for professionals who need the freedom to move between calls at home or in the office. It combines an extended wireless range, a noise-cancelling microphone and comfortable on-ear cushions with flexible connectivity for compatible computers and smartphones. The included BT700 USB-C adapter and desktop charging stand provide a practical, ready-to-use solution for everyday communication.
Freedom to Work Away from Your Desk
Move around your workspace while remaining connected, with a wireless range of up to 50 metres when using the included BT700 USB-C adapter. The headset can pair with up to eight devices, helping users switch between compatible work and personal devices more easily.
Clearer Conversations
A two-microphone noise-cancelling system works with Poly Acoustic Fence technology to help reduce distracting background noise during calls. The stereo on-ear design also provides a speaker bandwidth of 20 Hz to 20 kHz for calls, music and other everyday audio.
Built for a Full Working Day
Enjoy up to 24 hours of wireless talk time when the online indicator is switched off, or up to 18 hours with the indicator active. The rechargeable lithium-ion battery takes less than 1.6 hours to charge, while the supplied desktop stand offers a convenient place to store and recharge the headset between calls.
Flexible Wireless and Corded Use
Connect to compatible computers through the BT700 USB-C adapter or use Bluetooth 5.1 with compatible PCs and smartphones. If additional working time is needed, the headset can also carry audio while connected in corded USB mode.
Practical Call Controls
Controls on the headset provide convenient access to call answering and ending, microphone mute, volume adjustment, power and Bluetooth pairing. A visible on-call indicator flashes on the ear cup during calls, helping colleagues recognise when the user is busy.
Comfort and Hearing Protection
The lightweight stereo headset weighs 158 g and uses on-ear cushions with an artificial leather surface. Poly SoundGuard Digital acoustic protection technology helps protect against excessive sound exposure during regular use.
