Engage 45 SE Monaural DECT Headset

The Jabra Engage 45 SE is a mono wireless headset built for desk-based professionals. It connects through a DECT base station to a deskphone and offers 13 hours of talk time. The over-the-ear design weighs 1.1 lb and covers a frequency range of 40 Hz to 16 kHz. DECT Security Certification is supported via the companion app.

Suited for Single-Ear Office Use

This model suits users who need to stay aware of their surroundings while on calls. The monaural driver leaves one ear open for colleagues or announcements. Buyers who require stereo audio for multimedia or dual-ear noise isolation should look at a binaural alternative. The 328.1 ft wireless range supports mobility across a large floor.

Deskphone Integration and Workspace Freedom

The headset pairs with the supplied DECT base that plugs into a compatible deskphone. Wireless operation frees the user from the handset cord during long conversations. App-enabled features allow security settings and firmware updates without extra cables. The package includes the headset, base station and charging components.

Questions about this item

Do I need a desk phone or the DECT base to use this headset?

Yes, the Engage 45 SE connects through a desk phone or the supplied DECT base; it has no direct USB or Bluetooth link to a computer.

Will the 328.1 ft DECT range still work if I keep an older cordless phone on the same desk?

DECT operates in its own band, so the headset and a legacy cordless phone can coexist without interference.

How can I confirm the headset is delivering the full 40 Hz to 16 kHz response after pairing?

Play a wide-band test tone or music track; you should hear clear lows at 40 Hz and crisp highs up to 16 kHz without drop-outs.
