Jabra Evolve 20 UC Mono USB-C Headset
The Jabra Evolve 20 UC is a wired mono headset built for unified communications. It connects via USB-C and includes an in-line control unit for call handling. The single 28 mm driver covers 150 Hz to 7 kHz, while the noise-cancelling microphone captures 100 Hz to 10 kHz. UC certification ensures compatibility with major softphone platforms.
Verify USB-C Port and Mono Fit
Before ordering, confirm the host device has a USB-C port that supports audio-class operation. The headset draws power from the bus at a rated 5 mW @ 0.4 V, maximum 10 mW @ 0.56 V. The control cable measures 95 cm and the headset cable 120 cm, so check reach to the workstation. The mono ear coupling covers only one ear, which may not suit users needing stereo playback.
Suited for Call-Centric Workers Not for Stereo Users
This model suits professionals who spend most of the day on voice calls and need a lightweight, bus-powered headset with simple inline controls. Buyers who want stereo sound for music or multimedia, a wireless connection, or a dual-ear design should look at other options. The 32 ohm impedance and 93.6 dB sensitivity are tuned for speech clarity rather than wide-range audio.

Questions about this item
What comes in the box with the Evolve 20 UC Mono headset and do I need to buy anything extra?
The package includes the headset, USB controller, foam ear cushions and documentation; no extra items are required for USB-C connection.
Which version of the Evolve 20 UC should I choose for general unified-communications use?
This 4993-829-289 model is the standard UC-certified variant; a separate Microsoft Teams-certified version exists if your organisation mandates Teams optimisation.
What does the 150Hz-7KHz frequency response mean for call quality on this headset?
The range covers the core speech band, so voices sound natural on calls while music playback is limited above 7KHz.
