Jabra Engage 40 Mono USB-A Headset

The Jabra Engage 40 is a wired mono headset designed for professionals who spend long hours on calls. It connects via USB Type-A and weighs 1.59 oz for all-day comfort. The over-the-head design uses a single supra-aural earpiece so you stay aware of your surroundings. A 5.25 ft cable gives freedom of movement at the desk.

Sustained Call Performance

SafeTone 2.0 technology actively limits sudden loud sounds to protect hearing during back-to-back conversations. The MEMS boom microphone isolates speech while suppressing background noise in busy offices. Frequency response of 50Hz-20KHz keeps voices natural without fatigue. USB power means no battery to manage during extended shifts.

Setup Checklist

Verify your computer has a free USB Type-A port for the connector. Confirm the operating system supports USB audio class drivers for plug-and-play operation. Ensure the mono earpiece style matches your preference versus a stereo alternative. Check that the 5.25 ft cable length reaches your workstation comfortably.

Questions about this item

Does the 1.59 oz weight and over-the-head design stay comfortable and cool during all-day calls?

At 1.59 oz the mono headset is very light, and the supra-aural ear cup rests on the ear rather than enclosing it, so heat build-up is minimal during extended use.

What port must my computer have for the USB Type-A connector to work without an adapter?

A standard USB Type-A port is required; the headset draws power and audio through that single connection.

Will the 50 Hz–20 kHz frequency response and MEMS boom microphone integrate cleanly with my older USB-A desk phone or PC?

Yes, the USB-A interface is backward-compatible with legacy USB ports, and the MEMS microphone with SafeTone 2.0 handles wideband voice without needing newer hardware.
