Jabra Evolve 20 UC Mono Office Headset USB-C — Proven Entry-Level Office Headset
The Jabra Evolve 20 UC Mono Office Headset USB-C (4993-829-289) is Jabra’s classic entry-level corded office headset, deployed in thousands of Singapore workplaces and call centres. Its USB-C connector plugs straight into modern laptops, and the mono design keeps one ear free so you never miss what’s happening around you. No battery, no pairing — dependable call audio from the moment you plug in. Note: this USB-C model has been discontinued by Jabra; its direct successor, the Evolve 20 SE with USB-C/A adapter, is linked above.
Noise-Cancelling Microphone with PeakStop Hearing Protection
A uni-directional electret condenser (ECM) noise-cancelling microphone on an adjustable boom arm filters background chatter out of your calls, while Jabra PeakStop technology (with EU Noise at Work and G616 compliance) removes sudden loud sounds before they reach your ears — protecting agents on long shifts.
In-Line Call Control Unit for Effortless Call Handling
The 2.15 m cable includes Jabra’s USB control unit with large, intuitive buttons: answer and end calls, adjust volume and mute without touching your PC. 28 mm speakers cover 150 Hz – 7,000 Hz in speak mode for clear voice, and 20 Hz – 20,000 Hz in music mode.
UC Variant — Works with All Leading Softphones
This UC variant is built for Unified Communications platforms — Zoom, Google Meet, Cisco Webex and more — and carries certifications for Alcatel-Lucent, Avaya, Cisco and Unify softphone environments. It presents as a standard USB audio device, so it works with practically any meeting app.
