Product Overview
AI-generated summary
The Jabra Biz 2300 Duo USB‑C is a solid “works out of the box” headset for day-to-day office calling and Teams/Zoom. For £99.98 ex‑VAT, you’re getting something that feels built for real use (not just meetings), and the mic quality is generally reliable enough that you won’t spend every call apologising for background noise. The dual‑ear comfort also pays off if you’re on calls for hours—your head doesn’t feel like it’s being squeezed by lunchtime.
That said, I wouldn’t treat it as a premium audio headset for power users. If you’re doing a lot of noisy open‑plan work or you’re picky about listening quality (music, detailed soundstage, etc.), it may feel a bit “business first” rather than “audiophile.” It’s best for organisations standardising simple, dependable USB‑C calling hardware—support desks, sales teams, internal comms—especially where you want fewer headaches and consistent mic performance across users.
