Professional wired USB headset

The Jabra EVOLVE 20SE is a stereo headset designed for office professionals who spend long hours on calls and need clear audio for music. It connects via a single USB plug and features an over-the-head design with soft leatherette ear cushions and an adjustable headband for all-day comfort.

Simple plug-and-play setup

Installation requires only an available USB port on a laptop or desktop; no drivers or software are needed to begin working. The inline control unit puts volume, mute, answer and end-call functions at your fingertips, reducing the chance of missed commands during a conversation.

USB audio and power limits

Because the headset draws both power and audio signal from the USB bus, it cannot operate on devices that lack a standard USB-A port or that provide insufficient bus power. The wired connection also restricts movement to the cable length, so users who need to roam away from their desk will find this model unsuitable.
