Professional Mono Headset for Office Calls

The Jabra EVOLVE 20 MS Mono is a wired, over-the-head headset designed for professionals who spend long hours on calls and meetings. It connects via USB for plug-and-play simplicity with Microsoft Teams and other leading softphone platforms. The single-ear circumaural design lets you stay aware of your surroundings while focusing on conversations.

Inline Control Unit and Passive Noise Reduction

A USB control unit provides 3.12 ft of cable between the PC and the controller, with a further 3.94 ft headset cable for comfortable reach. Buttons on the unit handle volume, mute, and call answer or end functions without touching the computer. Specially designed ear cushions create passive noise cancellation that blocks high-frequency sounds such as nearby voices.

Wired USB Limits and Single-Ear Constraint

The USB connection ties you to the host device and draws power from it, so mobility is limited by the combined cable length. Mono audio means you hear calls in one ear only, which is not suited for stereo music enjoyment or immersive multimedia. Buyers needing wireless freedom or dual-ear coverage should consider other form factors.
