Jabra Engage 55 Stereo MS — Secure DECT Wireless Headset for Back-to-Back Calls
The Jabra Engage 55 Stereo MS is a professional DECT wireless headset engineered for people who spend most of the day on calls. Its Jabra Link 400 USB-A DECT adapter gives you up to 150 m / 490 ft of wireless range from your laptop — roughly triple typical Bluetooth range — so you can stand, stretch or grab a document without dropping the conversation. DECT also side-steps congested Bluetooth and Wi-Fi bands, making it ideal for dense Singapore offices and call centres.
Noise-Cancelling Dual-Microphone System for Clear Calls
A dual-microphone system — an ECM uni-directional microphone paired with an analog MEMS microphone — isolates your voice and suppresses background chatter, while wideband speakers (40 Hz – 16,000 Hz in music mode) keep every word crisp. Note that noise cancellation on the Engage 55 is microphone-based: it keeps your callers from hearing your surroundings, and the closed stereo ear cushions provide passive damping for you.
Up to 13 Hours Talk Time with a User-Replaceable Battery
The rechargeable lithium-ion battery delivers up to 13 hours of talk time (busylight off) — enough for multiple working days between charges — and unlike most headsets it is user-replaceable, extending service life. This variant ships with the charging stand for convenient drop-in charging and a tidy desk.
Military-Grade DECT Security and Certified Hearing Protection
Engage 55 secures the wireless link with DECT Security Level C and FIPS 140-2 approved 256-bit encryption algorithms — the highest DECT security classification — so confidential conversations stay confidential. Jabra SafeTone 2.0 with PeakStop protects your hearing against sudden acoustic spikes and meets EU Noise at Work, G616 and OSHA guidelines, an important consideration for MOM workplace safety compliance in contact centres.

Frequently Asked Questions — Jabra Engage 55 Stereo
What is the difference between the Engage 55 MS and UC variants?
The hardware is identical. The MS variant ships with a Microsoft Teams-certified Link 400 adapter with a dedicated Teams notification light; the UC variant is tuned for Zoom, Google Meet, Amazon Chime and other platforms. The UC USB-A with charging stand version is part number 9559-415-111.
Does the Jabra Engage 55 have active noise cancellation (ANC)?
No — the Engage 55's noise cancellation is on the microphone side: the dual ECM + MEMS microphone system stops your callers from hearing background noise, and the stereo ear cushions give passive isolation. If you want speaker ANC for your own ears, consider the Jabra Evolve2 75 in our catalog.
Should I choose Stereo or Mono?
Stereo (83 g) covers both ears for maximum focus in noisy rooms; Mono (57 g) keeps one ear open for colleagues. Mono variants are linked in the ordering section above.
How does the Engage 55 connect — does it use Bluetooth?
No. It uses DECT wireless via the included Jabra Link 400 USB adapter, giving up to 150 m / 490 ft range, higher headset density than Bluetooth, and DECT Security Level C with FIPS 140-2 approved 256-bit encryption. There is no battery-draining Bluetooth pairing — just plug the adapter into a USB-A port.
The listing says this model is no longer available — what is the replacement?
Jabra has superseded this model with the Jabra Engage 55 SE Stereo, which is available from SourceIT; see the replacement links at the top of this page for the matching SE variant.
Does the Jabra Engage 55 come with a local warranty?
Yes. Every Jabra Engage 55 sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
