Microsoft Teams certified headset

The HP 77Y98AA Voyager 4320-M is a binaural on-ear headset certified for Microsoft Teams. It connects wirelessly via the included BT700 USB-A adapter and supports voice assistants such as Google Assistant and Siri. The wireless range reaches 164 ft, giving freedom of movement during calls. It suits professionals who need a dedicated Teams device with simple plug-and-play setup.

Bluetooth wireless range and audio bandwidth

The headset uses a Bluetooth connection through the supplied BT700 USB-A dongle for wireless operation. Audio response spans 20 Hz to 20000 Hz, covering the full audible spectrum for voice and multimedia. Wireless range extends to 164 ft in typical conditions, though walls and interference will reduce the practical distance. A 4.92 ft USB-A cable is included for wired use or charging when wireless is not required.

On-ear build with dual microphone array

The on-ear form factor rests on the ears rather than enclosing them, which keeps the headset light for long sessions. Two analog electret condenser microphones and two digital MEMS microphones combine for noise-cancelling pickup that suppresses background sound. The over-the-head band provides a secure fit, while the ear-cup design allows ambient awareness. This configuration suits open-plan offices where situational awareness matters.
