Portable mono headset for hybrid workers

The Jabra Evolve2 30 SE is a wired mono headset built for professionals who move between desk and home office. It connects through a USB-A plug and weighs 92 grams with cable, so it adds minimal bulk to a laptop bag. The 28 mm drivers cover a 20 Hz to 20 000 Hz music range and a 100 Hz to 12 000 Hz speak range.

Durable frame with inline controls

A 1.5 m cable gives enough reach to sit back from the host device without stretching. The headset carries a busylight that signals active calls and Microsoft Teams notifications, reducing interruptions in shared spaces. A felt pouch is included for scratch-free transport when the day ends.

Passive cooling and low power draw

With no battery and a maximum speaker input of 30 mW, the unit draws negligible power from the host and generates no fan noise. The lightweight 69 gram frame without cable avoids heat buildup against the ear during long sessions. Microphone sensitivity of -38 BV/Pa ensures clear pickup without extra gain.
