Work-from-anywhere headset

The HP 77Z31AA Voyager 4320 is an on-ear stereo headset built for professionals who split time between desk and mobile environments. It connects through Bluetooth using the supplied BT700 USB adapter or via a wired USB Type-A and Type-C cable. The package includes a desktop charge stand that extends daily talk time.

Desk and mobile workflow

Workers can roam up to 50 metres or 164 feet from the host device while staying on a call. The headset pairs with multiple devices simultaneously, letting users switch between a laptop and a phone without re-pairing. When battery runs low the USB wired mode keeps the conversation going without interruption.

Charge stand and voice control

The included stand provides a dedicated docking spot that recharges the headset between calls, supporting up to 24 hours of wireless talk time. A dedicated button activates Siri or Google Assistant for hands-free commands. Acoustic Fence technology reduces background noise so the far end hears only the speaker's voice.
