Stay connected while staying aware of your surroundings with the Evolve 40 Mono Headset from Jabra. The single earcup design lets you take calls and have conversations without having to take off your headset. When on a call, the integrated busy light lets everyone know you’re not to be disturbed. The headset connects to the included USB controller via a standard 3.5mm headphone connector. The puck-shaped controller then plugs into your computer or mobile device via USB Type-C. It’s certified for use with a host of communication platforms and softphones. When you’re not on a call, you can spin the boom mic up and magnetically attach it to the headband.

For Calls or Music
Since the Evolve 40 connects to the USB Type-C controller via a standard 3.5mm headphone connector, you can easily disconnect and plug into your compatible mobile device to enjoy your favorite music, podcasts, or audio books.
