What it is
The Jabra Evolve 20SE UC Mono is a wired, monaural USB-A headset built for office and call centre use. It connects via USB Type-A, weighs just 142 g, and needs no drivers — plug it in and it works. The boom microphone is noise-cancelling, certified for Microsoft Teams, and backed by Jabra's IntelliTone and SafeTone hearing protection technologies.
Who it's for
This headset suits office workers, helpdesk teams, and call centre agents who spend a large part of their day on calls. It's a solid choice for businesses rolling out UC platforms — particularly Microsoft Teams — and need a reliable, low-maintenance headset at a sensible per-seat price.
Why it's good
- Plug and play: No drivers, no setup — connects over USB Type-A and works immediately.
- Noise-cancelling boom mic: Unidirectional back electret condenser with DSP keeps your voice clear and cuts background noise.
- Hearing protection built in: Jabra SafeTone and IntelliTone limit prolonged sound exposure — important for all-day call centre use.
- Microsoft Teams certified: Works reliably with Teams calls without fiddling with settings.
- In-line controls: Volume up/down and mic mute on the cable — no need to reach for the screen.
- HD voice & 2.15 m cable: Clear audio and enough cable length for a standard desk setup.
When to choose it
Choose the Evolve 20SE UC Mono when you need a dependable, no-fuss headset for UC calls and don't need stereo audio. It's a strong fit for multi-seat rollouts where cost per unit matters and reliability is non-negotiable. If your team needs stereo sound or spends time in loud open-plan spaces where active noise cancellation would help, it's worth stepping up to the Evolve 40 range instead.
