Jabra Evolve 20 UC Stereo — 4999-829-269
The Jabra Evolve 20 UC Stereo is an entry-level professional wired headset optimised for Unified Communications. Unlike the MS variant, it is certified for the full range of UC platforms — including Cisco, Avaya, Alcatel-Lucent, Unify and any SIP-based softphone — making it the right choice for organisations that are not exclusively on Microsoft Teams.
The 4999-829-269 variant ships with both a USB-C and a USB-A cable, covering modern and legacy laptops in a single SKU. The in-line control unit provides one-touch access to answer/end calls, adjust volume and mute without touching the computer. Digital Signal Processing (DSP) optimises voice quality during calls, and the noise-cancelling boom microphone reduces background noise for clear transmission.
Passive noise isolation from the on-ear foam cushions reduces high-frequency ambient sound. Setup is fully plug-and-play on Windows and macOS — no drivers required.

Frequently Asked Questions
Singular Recommends
For who
IT managers in organisations running Cisco, Avaya, Alcatel-Lucent or mixed UC environments who need a cost-effective, certified wired headset. Also the right choice for businesses that may migrate UC platforms in the future — the UC certification is not locked to a single vendor.
The real reason to buy it
UC certification covers a far wider range of platforms than MS certification. If your organisation runs Cisco Jabber, Avaya Communicator or any SIP softphone alongside or instead of Teams, this is the correct headset — the MS version will work but without native call control integration on those platforms.
Know before you buy
On-ear design — cushions rest on the ear, not surrounding it. USB connection only; no 3.5mm jack. The Teams-button shortcut does not work on this model. If your organisation is exclusively on Microsoft Teams and requires the Teams button, choose the MS variant (4999-823-169) instead.
