Wired Mono Headset for Unified Communications

The Jabra Evolve 30 II is a wired monaural headset built for professionals who spend long hours on calls with phones, laptops and smart devices. It connects through a 4-pin USB type-A interface or a 3.5 mm jack and includes a 95 cm control cable plus a 120 cm headset cable. A noise-cancelling electret condenser microphone and PeakStop technology help keep speech clear in open offices.

Upgrade from Basic Earbuds or Built-In Audio

Users moving from simple earbuds or laptop speakers gain a dedicated boom microphone with a 100 Hz to 10 kHz pickup range and HD Voice support. The jump is worth it when calls require consistent wideband audio and easy inline call management without software setup. UC plug-and-play operation means it works immediately on major platforms.

Limits of the Analog and USB-A Interfaces

The 3.5 mm connection relies on the host device for power and conversion, so microphone sensitivity stays between -42 and -38 dB and speaker output is capped at 10 mW input. Frequency response reaches 150 Hz to 7 kHz on the earpiece, which suits voice but not full-range music. Operating temperature spans -10 to 50 °C.

Questions about this item

What type of USB port does the 4-pin USB type-A connector on this headset require?

The headset connects through a standard 4-pin USB type-A port on a computer or laptop for power and audio.

How should the 95 cm control cable and 120 cm headset cable be routed during setup?

Connect the headset cable to the inline control unit, then plug the control cable into the USB type-A port; avoid sharp bends near the boom microphone.

When should the ear cushion on this monaural headset be replaced?

Replace the ear cushion when the leatherette shows cracking or the foam no longer seals against the ear, which affects passive noise isolation.
