Wireless Headset

Poly Voyager Wireless Bluetooth Headset.
Model 4320 UC.

Talk time is between 10-12 hours.
Comes with Bluetooth dongle (not required but improves the range). Can also be connected to your phone via Bluetooth as well. If you have other Poly devices you can also link them to the dongle using their desktop app. Also comes with a black headset cover.

Charged via USB-C (cable not included)

Used only a couple of times. I received some airpods over Xmas and have been using those instead.
