Unified Communications Headset

The Jabra Engage 55 is a mono wireless headset built for contact centres and offices with extreme daily usage. It connects via USB-A and uses DECT 1.9 technology for secure, interference-free calls. The titanium black design includes an over-the-head wearing style for all-day comfort.

A protective bag is supplied for safe storage and transport. Jabra Direct software enables firmware updates and device personalisation from the desktop. Unified Communications certification ensures plug-and-play compatibility with major softphone platforms without extra configuration.

DECT Interface Limits

DECT 1.9 operates in a dedicated 1.9 GHz band, avoiding Wi-Fi and Bluetooth congestion but limiting roaming to the base station range.

Questions about this item

Will the DECT 1.9 USB dongle or the mono earpiece need replacing first under heavy daily use?

The DECT 1.9 USB adapter and mono headset are built for extreme usage frequency; the rechargeable battery inside the headset is the component most likely to require replacement after prolonged daily cycles.

What limits talk time during a full shift of back-to-back calls?

Battery capacity limits continuous talk time; the headset supports USB charging so you can top up during breaks, and Power Nap extends standby when the headset is idle.

How much heat or fan noise does the base generate when the headset runs all day?

The USB-A dongle has no fan and draws minimal power, so it produces negligible heat and zero audible noise during extended operation.
