Jabra Engage 55 MS Mono — DECT Wireless Headset on a USB Adapter
DECT, up to 150 mLink 400 MS with Teams buttonUp to 13 h talk57 g, user-replaceable battery
The Jabra Engage 55 MS Mono, order code 9553-450-111, is a single-ear DECT wireless office headset that connects through a USB-A adapter rather than a base station. DECT gives it the density and security that a busy floor of headsets needs, and up to 150 metres of range means you can leave the desk mid-call. At 57 grams with a battery you can replace yourself, it is built to stay in service rather than be thrown away when the cell tires.
Compatibility — check before buying:
There is no desk-phone connection. The Engage 55 works through its Link 400 USB adapter and nothing else, so if you are replacing an Engage 65 or 75 that was wired into a desk phone, that function does not carry over. This is the MS build with the USB-A adapter. The Teams button and the purple Teams notification light live in the Link 400 MS adapter, and Jabra states plainly that the full Teams experience only exists when the MS adapter is paired with the MS headset — the UC code 9553-410-111 has neither. If your machines are USB-C only, the correct order code is 9553-470-111 rather than putting a dongle adapter on a DECT stick. No charging stand is included with this article; the stand versions are 9553-455-111 and 9553-475-111. Finally, 9553-450-125 is the North American pack of the same headset — one digit apart, wrong region.
Best For
✓ Contact centres and open-plan floors with many headsets in one space
✓ Desk workers who need to walk away mid-call
✓ Microsoft Teams deployments wanting a hardware Teams key
✓ Sites that prefer DECT density and security over Bluetooth
✓ Organisations that replace batteries rather than headsets
✓ Small huddles — up to four headsets can share one adapter
Key Features
DECT with FIPS-grade encryption
Jabra publishes FIPS 140-2 algorithms and 256-bit encryption, stating it exceeds DECT Security Step C. On a floor full of wireless headsets, DECT also avoids the congestion that Bluetooth suffers.
Up to 150 m and up to 13 hours
Range up to 150 m from the adapter, and up to 13 hours of talk time with the busylight off. The lithium-ion battery is user-replaceable on the Mono model, so a tired cell is a part, not a new headset.
Teams button in the Link 400 MS adapter
The adapter carries the Microsoft Teams key and pulses purple for Teams notifications. Because it lives in the adapter rather than the headset, the MS and UC builds are not interchangeable after purchase.
Dual microphone and full hearing protection
An ECM uni-directional element paired with an analog MEMS system across 100 Hz to 7.3 kHz, with Jabra PeakStop, SafeTone 2.0, G616, EU Noise at Work and OSHA protection listed.

Frequently Asked Questions
Singular Expert Insight
The Engage 55 is the headset to pick when a floor full of people all need wireless at once — DECT handles density in a way Bluetooth does not, and the security specification is genuinely strong rather than marketing. The user-replaceable battery on the Mono model is the detail that matters over three years of ownership. What you must get right at the order stage is the adapter: MS or UC decides whether you have a Teams button, USB-A or USB-C decides whether it plugs into your machines, and stand or no stand decides how people charge it — and all three are separate order codes for the same headset. This one is MS, USB-A, no stand. Also be clear with the team that there is no desk-phone path here. Our office and VoIP headsets range covers the base-station models if you need one.
Buyer’s Guide
Buy it if
You are fitting wireless headsets on a Microsoft Teams floor, the machines have USB-A, and you want DECT range and security with a battery your own staff can replace.
Skip it if
You need a desk-phone connection, your machines are USB-C only, or your softphone is not Teams. Each of those is a different order code in the same family, and we can confirm which.
Also consider
The stand versions 9553-455-111 (USB-A) or 9553-475-111 (USB-C) if desks should charge on a cradle, and the UC build 9553-410-111 for non-Teams platforms.
