Single-ear USB headset for Teams

The Jabra Evolve 20 4993-823-189 is a mono headset built for Microsoft Teams environments. It connects via USB Type-C and weighs 0.31 lb. The single-ear design keeps one ear open to the office while the noise-cancelling microphone filters background sound. It suits professionals who spend long hours on calls.

150 Hz to 7 kHz response with 93.6 dB sensitivity

The speaker covers 150 Hz to 7 kHz at 32 ohm impedance and 93.6 dB SPL at 1 kHz, delivering clear voice reproduction. The microphone picks up 100 Hz to 10 kHz with sensitivity between -48 dB and -44 dB. This range handles speech well but is not intended for music playback or wideband audio.

USB Type-C plug with inline control cable

A 95 cm control cable and 120 cm headset cable give enough reach for desk setups without excess slack. The USB Type-C connector plugs directly into modern laptops and docks. No separate audio jacks or driver installs are required. The inline unit places mute and volume within easy reach during calls.

Questions about this item

Will the USB Type-C connector on the Evolve 20 work with my older laptop that only has USB-A ports?

The headset uses a USB Type-C connector; you will need a USB-C to USB-A adapter or a dock with a USB-C port to connect it to a USB-A-only computer.

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

Make a test call in Microsoft Teams and listen for reduced keyboard or ambient noise; the microphone frequency response is 100Hz-10KHz with sensitivity between -48dB and -44dB.

What cables are included in the box and do I need to buy any extra adapters?

The box contains the mono headset with a 120 cm headset cable and an inline control unit on a 95 cm cable ending in USB Type-C; a USB-C to USB-A adapter is not included.
