PRODUCT DESCRIPTION
Jabra Evolve 20 SE MS Mono Headset + USB-C/A Adapter (4993-823-369) - 2 Years Local Warranty
Jabra Evolve 20 SE Specifications — Corded USB Headset with Leatherette Cushions
The Jabra Evolve 20 SE (4993-823-369) is a mono single-ear corded USB office headset built for straightforward, high-volume deployment. It uses 28 mm speakers and a noise-cancelling uni-directional electret condenser microphone, with an inline call-control unit for answer, end, mute and volume. There is no battery and no pairing — plug it in and it works, which is exactly what most Singapore offices want when rolling out headsets across a floor.
Plug-and-Play USB-C Connectivity with a USB-A Adapter Included
This part number is the USB-C/A version: it connects over USB-C and ships with a USB-A adapter, so the same headset works with a modern USB-C laptop today and with older USB-A docks and desktops already on your floor. No drivers, no charging and no pairing are required. Jabra notes that the USB-C connection is optimised for computers — connecting to a mobile phone or tablet may give reduced performance.
What Makes the SE Different: Leatherette Ear Cushions
The Evolve 20 SE is acoustically identical to the standard Evolve 20 — same 28 mm speaker, same microphone, same inline controller and cable. The defining difference is the ear cushion: the SE upgrades to soft leatherette, which wipes clean easily and holds up better in Singapore's humidity than the foam cushion on the base model. Passive noise cancellation comes from the on-ear cushion seal.
Hearing Protection and Inline Call Control
Jabra PeakStop limits sudden loud sounds, and the headset complies with EU Noise at Work and G616 requirements — relevant for contact-centre and support teams on the phone all day. The inline control unit handles answer and reject, end call, mute, and volume up and down, with a busylight and incoming-call indicator on the controller itself.
Platform: Microsoft Teams variant
This part number is the Microsoft Teams variant, with Teams notification support on the inline controller. The Evolve 20 SE range carries Jabra platform listings for Microsoft Teams (variant dependent), Alcatel-Lucent, Avaya, Cisco and Unify, with regulatory approvals covering CE, FCC, KCC, RCM and UL.

Frequently Asked Questions — Jabra Evolve 20 SE
What is the difference between the Evolve 20 SE MS and UC variants?
The hardware is identical — the difference is certification and default call-control behaviour. The MS part numbers (4993-823-369 mono and 4999-823-369 stereo) are the Microsoft variant, with Teams notification support on the inline controller. The UC part numbers (4993-829-469 and 4999-829-469) are optimised for other leading Unified Communications platforms including Avaya, Cisco, Alcatel-Lucent and Unify.
Should I choose mono or stereo?
Mono (single-ear, 104 g) leaves one ear open so you can hear colleagues around you — the usual choice for contact centres and reception desks. Stereo (dual-ear, 132 g) covers both ears for better concentration in an open-plan office. This listing is the Mono (single-ear) version; the stereo (132 g) version is available here.
What is the difference between the Evolve 20 and the Evolve 20 SE?
They are acoustically the same headset — same 28 mm speaker, same noise-cancelling ECM microphone, same inline controller, same cable. The SE upgrades the ear cushion from foam to soft leatherette, which is easier to wipe clean and more durable in a humid climate. Everything else, including certifications, is identical.
Does the Evolve 20 SE need charging or Bluetooth pairing?
No. This is a corded USB headset with no battery and no Bluetooth. It draws power from the computer over USB, so there is nothing to charge and nothing to pair — which also means there is no battery to degrade over a three-year deployment.
What does the USB-C/A adapter version mean?
This part number terminates in USB-C and ships with a USB-A adapter in the box, so it works with both modern USB-C laptops and older USB-A machines and docks. Jabra also produces USB-A-only (-309 / -409) and USB-C-only (-389 / -489) versions of the same headset.
How does the Evolve 20 SE compare with the Evolve 30 II and Evolve 40?
The Evolve 20 SE is the entry-level corded model. The Evolve 30 II adds a 3.5 mm connection alongside USB and a busylight on the headset itself. The Evolve 40 steps up again with larger speakers and a more capable inline controller. Choose the Evolve 20 SE when you need a reliable, low-cost headset in volume.
Does SourceIT provide local warranty for the Evolve 20 SE?
Yes. Every Evolve 20 SE sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
