Entry-level wireless headset

The Plantronics 76U49AA Voyager 4320 is a new on-ear Bluetooth headset built for professionals who need to move around while staying connected to calls. It supports both stereo and mono audio modes and pairs with devices via Bluetooth wireless technology. The binaural design covers both ears for focused listening in busy environments.

Dual USB connectivity and voice control

A 4.92 ft cable provides USB Type-A and USB Type-C connections for wired audio or charging while the headset remains wireless for calls. Integrated support for Siri and Google Assistant allows hands-free voice commands without reaching for a paired phone or computer. This flexibility lets users switch between corded and wireless operation instantly.

50-metre range with all-day comfort

Bluetooth range extends up to 50 metres or 164 feet, giving users freedom to walk around large offices or home workspaces. The frequency response spans 20 Hz to 20 kHz for clear voice reproduction. Buyers needing longer battery life than a single shift provides or specialised noise-cancelling certification should evaluate higher-tier models.

Questions about this item

What is the wireless range before the Bluetooth connection drops?

The headset maintains a Bluetooth link up to 50 meters or 164 feet (300 ft in the spec sheet) from the paired device.

What limits continuous use during a full workday?

Battery capacity is the limiting factor; the headset must be recharged via the USB cable once the charge is exhausted.

How much heat or noise does the headset produce when worn all day?

The on-ear design runs silently and generates no noticeable heat; only the ear cups may feel warm after extended wear.
