Jabra Evolve 20 USB-A Headset

The Jabra Evolve 20 is a wired circumaural headset designed for office communications. It connects through a USB-A port and includes an inline control unit for call handling. The 28 mm drivers produce a frequency response of 150Hz-7KHz tuned for voice clarity.

Suited For Desk-Based Voice Work

This model suits professionals who spend long hours on calls at a fixed workstation and want a lightweight headset with simple USB connectivity. Buyers who need wireless freedom, active noise cancellation or a different analogue connector should look at other products.

USB-A Connector Decides Compatibility

The single specification that determines fit is the USB-A connector; the host device must provide a compatible port and driver support. Without an available USB-A socket the headset cannot function, so verify the port before purchase.

Questions about this item

Does my computer need a USB-A port for the Jabra Evolve 20 headset?

Yes, the headset connects through a USB-A connector so the host device must provide a USB-A socket or a compatible adapter.

Will the 95 cm control cable reach my desktop tower if I keep the PC under the desk?

The control cable measures 95 cm and the headset cable 120 cm, giving a combined length that typically reaches a floor-standing tower from a seated position.

How can I confirm the microphone is active after plugging in the Evolve 20?

The inline control unit has a microphone mute button with an LED indicator; when the LED is off the microphone is live and transmitting audio.
