Jabra Evolve2 55 UC Mono Wireless Headset USB-C (25599-889-899) - 2 Years Local Warranty
Jabra Evolve2 55 UC Mono Wireless Headset USB-C — Wireless ANC Headset for Hybrid Work in Singapore
The Jabra Evolve2 55 UC Mono Wireless Headset USB-C (25599-889-899) is a professional Bluetooth 5.2 headset built for hybrid teams that split their week between the office and home. It pairs Active Noise Cancellation with a single-ear (mono) on-ear design weighing just 79 g, and ships with the Jabra Link 380c (USB-C) plug-and-play adapter so calls connect instantly on a laptop or dock. Sold by SourceIT with a GST invoice and 2 years local Singapore warranty.
Active Noise Cancellation and 3-Microphone Call Technology
Jabra's Active Noise Cancellation (ANC) quiets the hum of an open-plan office or a busy home so you can concentrate on the conversation. On the call side, 3 microphones (1 analog MEMS + 2 digital MEMS) work together to isolate your voice from surrounding noise, while PeakStop™ and Jabra SafeTone™ guard your hearing against sudden loud sounds across long shifts. The adjustable boom arm folds neatly into the headband when it is not in use.
Up to 18 Hours of Battery with Fast Charging
A single charge delivers up to 18 hours of music (ANC off) or up to 15 hours with ANC on, and up to 16 hours of talk time with ANC and busylight off — comfortably more than a full working day. A 30-minute top-up restores roughly 50% of the battery, and a full charge takes up to 120 minutes over the USB-C™ charging port.
Built for Zoom, Google Meet, Cisco Webex and Other UC Platforms
This UC variant is certified across a broad range of Unified Communications platforms including Zoom, Google Meet, Cisco, Amazon Chime, Avaya, Alcatel-Lucent, Unify and DingTalk, so it slots into whatever stack your business already runs. The integrated busylight turns red the moment you take a call, signalling to colleagues that you should not be interrupted.
Bluetooth Multipoint: Laptop and Mobile at the Same Time
Connect to two devices at once and remember up to eight, so you can move from a laptop meeting to a mobile call without re-pairing. Wireless range reaches up to 30 m (100 ft), and the Jabra Link 380c (USB-C) adapter gives a reliable, IT-approved connection that does not depend on your laptop's built-in Bluetooth. Google Fast Pair (Android) and MFi support round out mobile compatibility.

Frequently Asked Questions — Jabra Evolve2 55
Q: What is the difference between the Evolve2 55 MS and UC variants?
A: The hardware is identical. The MS variant is certified for Microsoft Teams and Microsoft Teams Rooms and carries a dedicated Teams button; the UC variant is certified across Zoom, Google Meet, Cisco, Avaya, Alcatel-Lucent, Unify and others. Both work with all major softphones. This listing is the UC variant — the MS equivalent is Jabra Evolve2 55 MS Mono Wireless Headset USB-C (25599-899-899).
Q: Should I choose Mono or Stereo?
A: Mono (single ear, 79 g) leaves one ear open to your surroundings — preferred at reception desks, in service teams and on trading floors. Stereo (both ears, 130 g) gives stronger focus, better ANC performance and proper music playback in noisy open offices. This is the Mono version — see the Stereo version here: Jabra Evolve2 55 UC Stereo Wireless Headset USB-C (25599-989-899).
Q: How long does the battery last, and how fast does it charge?
A: Up to 18 hours of music with ANC off, up to 15 hours with ANC on, and up to 16 hours of talk time with ANC and busylight switched off. A full charge takes up to 120 minutes via USB-C, and a 30-minute top-up restores around 50% of the battery. A charging stand is not included with this part number.
Q: Can it connect to my laptop and phone at the same time?
A: Yes. The Evolve2 55 supports Bluetooth multipoint with two simultaneous connections and remembers up to eight paired devices, so you can stay on your laptop's meeting while your mobile stays connected for incoming calls. Range is up to 30 m, and the bundled Jabra Link 380c (USB-C) adapter gives a more stable, IT-manageable link than most built-in laptop Bluetooth radios.
Q: How does the Evolve2 55 compare with the Evolve2 50, Evolve2 65 and Evolve2 75?
A: The Evolve2 50 is the wired/USB sibling with ANC but no battery. The Evolve2 65 is wireless with a longer battery but no ANC. The Evolve2 55 sits between them — wireless and ANC, with the same 28 mm speakers. Step up to the Evolve2 75 for a dual-foam over-ear design, 8-microphone call technology and a longer battery.
Q: Does the Jabra Evolve2 55 UC Mono Wireless Headset USB-C come with warranty in Singapore?
A: Yes. Every Evolve2 55 sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
