Jabra Evolve 20 Mono Headset

The Jabra Evolve 20 is a wired mono headset built for professionals who spend long hours on calls. Its over-the-head design and single ear cup keep one ear open to the office while the USB connection provides instant compatibility with leading communication platforms.

Passive noise cancellation and mono speaker

Specially designed ear cushions deliver passive noise cancellation by reducing high-frequency sounds such as nearby voices. The 32 ohm mono speaker focuses audio on the active ear, ensuring clear incoming voice reproduction without blocking ambient awareness completely.

Questions about this item

Will the USB connector on the Evolve 20 work with the USB-A ports on my older PC?

Yes, the USB connector plugs directly into standard USB-A ports found on older desktops and laptops.

How can I confirm the noise-cancelling microphone is filtering background sound after I plug it in?

Make a test call; the person on the other end should hear your voice clearly while keyboard and office noise are suppressed.

Does the box include a carrying case or do I need to buy one separately?

The package contains the headset with integrated control unit and ear cushion; a carrying case is not included.
