Jabra Evolve2 40 SE MS Mono Wired Headset — Professional Audio for Singapore Offices
The Jabra Evolve2 40 SE MS Mono (24189-899-999) is a wired professional office headset engineered for busy, open-plan workspaces. With 40 mm speakers, a noise-isolating on-ear design and 3-microphone call technology, it delivers clear, dependable call quality over a simple plug-and-play USB-A connection — no batteries, no pairing, no downtime. It is a popular choice for contact centres, hybrid workers and corporate deployments across Singapore.
Certified for Microsoft Teams
This MS variant is certified for Microsoft Teams. Plug it in and the dedicated Teams button and busylight integrate directly with the Teams client, with incoming-call and notification alerts handled on the headset. If your organisation runs on Teams, the MS variant gives you the most seamless out-of-the-box experience.
3-Microphone Call Technology With Noise-Isolating Design
Three digital MEMS microphones on an adjustable boom arm capture your voice accurately (100 Hz–14 kHz speak bandwidth), while the single-ear mono design keeps you aware of colleagues around you. Jabra SafeTone hearing protection (PeakStop, EU Noise at Work, G616) keeps volume levels safe through long shifts. Note: this is a passive noise-isolating headset — it does not use active noise cancellation (ANC).
360° Busylight and All-Day Comfort
An integrated busylight, visible from all angles, signals to colleagues when you are on a call — a practical do-not-disturb sign for open offices. At just 113 g the mono design stays comfortable through a full workday, and the reinforced headband and simple wired connection make it a durable, low-maintenance fleet headset.

Frequently Asked Questions — Jabra Evolve2 40 SE
Q: What is the difference between the Jabra Evolve2 40 SE MS and UC variants?
A: MS variants are certified for Microsoft Teams and include a dedicated Teams button with native Teams busylight notifications. UC variants are certified for platforms such as Zoom, Google Meet and Cisco. Both work as standard USB audio devices on all major platforms — choose MS if your organisation standardises on Teams.
Q: Should I choose the mono or stereo version?
A: Mono (single ear, 113 g) keeps one ear open so you stay aware of your surroundings — popular in contact centres and reception desks. Stereo (both ears, 188 g) passively isolates more office noise and is better for focused work, music and video meetings.
Q: How does the Evolve2 40 SE compare with other Jabra headsets at SourceIT?
A: The Evolve2 40 SE sits above the entry-level Jabra Evolve2 30 SE with larger 40 mm speakers, a 360° busylight and a more robust build. If you want wired convenience plus hybrid work features such as active noise cancellation, consider the Jabra Evolve2 50. For wireless freedom, look at the Jabra Evolve2 55.
Q: Does the Jabra Evolve2 40 SE need charging or a battery?
A: No. It is a wired USB headset powered directly by your computer — no battery, no charging, no Bluetooth pairing. It is ready the moment you plug it in, which also makes it ideal for shared desks and shift work.
Q: Does the Evolve2 40 SE have active noise cancellation (ANC)?
A: No. It uses a passive noise-isolating design with sealed ear cushions rather than electronic ANC. The 3-microphone boom arm still removes background noise from your outgoing call audio, so callers hear you clearly. If you need ANC, see the Jabra Evolve2 50 or Evolve2 75.
Q: Does the Jabra Evolve2 40 SE come with a warranty in Singapore?
A: Yes. Every Jabra Evolve2 40 SE sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
