Jabra Engage 55 UC is a lightweight cordless headset that uses DECT for incredibly secure wireless communications with a wandering range you won't believe. The headset has a dual microphone array for noise reduction - with speakers optimized for speech clarity. Jabra SafeTone 2.0 protects your ears from longtime damage from loud sounds. A built-in busylight lets colleagues know when you're on a call. With Engage 55, you get all-day power - up to 13 hours of talk time. The rechargeable Li-ion battery is user replaceable. Charge the headset via the included USB cable or via its optional charging stand (not included).

Included in the package is a Jabra Link 400 DECT Adapter - arrives prepaired with the headset. This space-efficient, portable dongle means you can use the DECT headset with a softphone on your computer directly - no base station required. Using DECT gives the headset a greatly extended wireless range compared with Bluetooth headsets - up to 490 feet! The headset and adapter exceed the Secure DECT Level C standard with 256-bit AES encryption and more - ultra-secure communications. The Link adapter has a puck with flexible connector design for portability and durability - with a convenient light to let you know status. Because it's a USB adapter, Engage 55 UC is compatible with almost every communications platform and service on the market today. The headset is Zoom Certified and Google Meet Certified.
