Core numbers at a glance

Hands‑free clarity for busy calls

The noise‑cancelling boom microphone uses MEMS technology and covers 100–6800 Hz, so your voice stays clear in busy offices. Because the HP Poly Voyager 4320 USB-A Headset +BT700 dongle uses Bluetooth 5.1, you get a stable link across the desk or room. In practice, teams hear you first time, cutting repeat questions and hold time.

All‑day battery for non‑stop shifts

With up to 24 hours of talk time and 47 hours of audio playback, this headset runs through long shifts without a top‑up. The built‑in Li‑Ion battery recharges in 1.6 hours, and standby lasts 50 hours. So you start Monday fully charged and finish Friday without fuss.

Seamless plug‑and‑play with BT700 dongle

The bundled BT700 USB‑A adapter delivers instant Bluetooth pairing to PCs and laptops, even when IT policy blocks internal Bluetooth. It also supports smartphones via native Bluetooth, so one device covers desk and mobile use. For example, you can switch from a Teams call on your laptop to a mobile call in seconds.

Comfortable binaural design for focus

The supra‑aural, binaural ear cushions sit gently on the ears while blocking ambient noise. At 122 g with an adjustable headband, it stays comfortable through long meetings. Because the design is lightweight yet sturdy, users forget they are wearing it by mid‑morning.

Poly Lens management and cross‑platform support

Poly Lens desktop software lets IT teams monitor device health, update firmware, and apply call‑handling policies across Windows, macOS, Android, and iOS. This keeps the fleet consistent and reduces support tickets. For example, you can push a firmware update to every headset overnight.
