ENGAGE-75D-SE-UCJabra Engage 75 SE Dual Headset with DECT + Bluetooth connectivity USB A
The Engage 75 SE Dual is the top of Jabra's wireless DECT range in its dual-ear form: a base-station headset built for people who spend the whole day on calls and need to move around the office while they do it. The DECT link to the included base is paired with Bluetooth connectivity, so the same headset serves your desk phone, your PC softphone and your mobile.
Prefer a single-ear design so you can keep one ear on the room? Look at the Engage 75 Mono or the SE mono variant, the Engage 75 SE UC. If you do not need Bluetooth on top of DECT, the Engage 65 Stereo covers desk phone and PC for less.

Frequently asked questions
Will it connect to my desk phone?
Yes — an RJ9 cable ships in the box for a direct connection between the Engage 75 base and a desk phone. Tell us your phone model and we will confirm the right hook-lifter or EHS option for remote answering before you order.
What is the difference between this and the Engage 75 Mono?
Only the wearing style. This is the dual-ear (duo) version, which covers both ears for better focus in loud environments; the mono version leaves one ear free for conversations around you.
Does it work with PCs as well as phones?
Yes. A USB-A to USB-C cable is included for connecting the base to a PC for softphone calls, alongside the desk phone and Bluetooth options.
What is in the box?
The Engage 75 Duo headset, Engage 75 base, USB-A to USB-C cable, RJ9 cable, 7.5V power supply with UK and Australian plug adaptors, and a quick start guide.
