Jabra Engage 55 SE Mono UC – Professional DECT Wireless Headset for Singapore Offices
The Jabra Engage 55 SE Mono UC Wireless DECT Headset with Stand USB-C (9653-435-111) is a secure, professional-grade wireless DECT headset engineered for call-intensive work. With up to 150 m (490 ft) of wireless range from the included Jabra Link 400 USB-C DECT adapter, you can move freely around the office, answer calls away from your desk, and stay connected across large workspaces in Singapore CBD offices, contact centres, and hybrid work setups. The included charging stand keeps the headset docked, charged, and ready at your desk.
UC Certified for Zoom, Google Meet and Leading Platforms
This UC variant is Zoom Certified, works with Google Meet and Amazon Chime, is Works With Chromebook certified, and is built to work with all leading Unified Communications platforms — an ideal choice for organisations running mixed collaboration environments.
Enterprise-Grade DECT Security with FIPS 256-Bit Encryption
Jabra Engage 55 SE goes beyond DECT Security Level C, using FIPS 140-2 algorithms with military-grade 256-bit encryption for eavesdrop-protected conversations — essential for finance, government, healthcare, and legal teams handling confidential calls.
Noise-Cancelling Microphone and All-Day Mono Comfort
A dual-microphone system (ECM uni-directional plus analog MEMS) blocks out background noise so customers hear you, not your office. The single-ear mono design keeps you aware of colleagues around you while you talk, at an ultra-light 57 g. PeakStop™ and Jabra SafeTone™ 2.0 hearing protection keep you safe on long shifts, and the built-in busylight signals to colleagues when you are on a call.
Up to 13 Hours Talk Time with Fast Charging
A user-exchangeable rechargeable lithium-ion battery delivers up to 13 hours of talk time. Fast charging reaches 40% in 30 minutes and 80% in 60 minutes, with a full charge in up to 90 minutes — more than enough for the longest workday.

Frequently Asked Questions — Jabra Engage 55 SE Mono UC
Q: What is the difference between the UC and MS versions of the Jabra Engage 55 SE?
A: The UC version is Zoom Certified and built for all leading UC platforms including Google Meet and Amazon Chime. If your organisation standardises on Microsoft Teams, choose the Mono MS USB-C with Charging Stand (9653-475-111) for the certified Teams experience. Hardware and audio performance are otherwise identical.
Q: Should I choose the Mono or Stereo version?
A: The Mono (single-ear) version is an ultra-light 57 g and keeps one ear open so you stay aware of colleagues — popular for reception, retail, and supervisory roles. For noisy open-plan offices or focus-heavy call work, the dual-ear Stereo UC USB-C with Charging Stand (9659-435-111) (83 g) shields both ears and delivers richer audio.
Q: How does the Engage 55 SE compare with the Jabra Engage 55 in the SourceIT catalog?
A: The Engage 55 SE is the newer special-edition package of the same professional DECT platform — same up-to-150 m range and secure DECT performance — shipping with the pre-paired Jabra Link 400 adapter and travel pouch. You can compare it with the original Jabra Engage 55 Stereo UC (9559-410-111) in our catalog. If you prefer Bluetooth over DECT, see the Jabra Evolve2 65 UC Stereo (26599-989-999).
Q: How long does the battery last, and how fast does it charge?
A: Up to 13 hours of talk time from a user-exchangeable lithium-ion battery. Fast charging delivers 40% in 30 minutes and 80% in 60 minutes; a full charge takes up to 90 minutes — the included charging stand makes desk charging effortless.
Q: What is the wireless range, and can it connect to multiple devices?
A: DECT gives you up to 150 m / 490 ft of range from the Link 400 USB-C adapter — far beyond typical Bluetooth headsets. The Engage 55 SE uses secure single-computer connectivity via its pre-paired adapter (it is a DECT headset, not Bluetooth), which also delivers rock-solid call stability in dense office environments with many wireless devices.
Q: Does the Jabra Engage 55 SE come with local warranty in Singapore?
A: Yes. Every Engage 55 SE sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
