Jabra Evolve2 50 MS Mono Headset + USB-C/A Adapter
PRODUCT DESCRIPTION
Jabra Evolve2 50 MS Mono Headset + USB-C/A Adapter (25089-899-799) - 2 Years Local Warranty
Jabra Evolve2 50 Mono Wired USB Headset with Active Noise Cancellation
The Jabra Evolve2 50 MS Mono Headset + USB-C/A Adapter is a professional mono USB headset built for open-plan offices, hybrid desks and contact centres in Singapore. Unlike entry-level wired headsets, the Evolve2 50 carries genuine Active Noise Cancellation built around a dedicated acoustic chamber design, so background chatter, aircon hum and keyboard noise fall away while you concentrate. Powered entirely over USB, there is no battery to charge and no dongle to lose — plug in and the headset is ready for the whole shift.
3-Microphone Noise-Cancelling Boom Arm for Clear Calls
Voice quality is handled by three microphones (1 analog MEMS and 2 digital MEMS) working together with a noise-cancelling boom arm, filtering the room out of your call so customers and colleagues hear only you. The boom arm mutes the moment you flip it up, which is far faster than hunting for a mute button mid-call. Microphone response covers 20 Hz - 10,000 Hz on the analog path and 100 Hz - 6,300 Hz digitally, tuned specifically for speech intelligibility rather than raw bandwidth.
Dual Connectivity — USB Plus Bluetooth 5.2 to Your Mobile
This is the feature that separates the Evolve2 50 from a plain corded headset. While it is plugged into your computer via USB-C cable with USB-C to USB-A adapter included, it can also hold a Bluetooth 5.2 connection to your mobile phone at up to 30 m range, with up to 8 devices remembered in its pairing list. Take the softphone call on your laptop, then answer your mobile without swapping headsets. One simultaneous Bluetooth connection is supported alongside the USB link.
28 mm Speakers, Busylight and All-Day Comfort
Custom 28 mm speakers cover 20 Hz - 20,000 Hz in music mode and switch to a speech-tuned 150 Hz - 6,800 Hz profile on calls, so the same headset handles a client presentation and a Spotify playlist. The integrated 360-degree busylight is visible from every angle and doubles as an incoming-call and Microsoft Teams notification indicator. At just 99 g the headset stays comfortable across back-to-back meetings, with a pressure-relieving headband, leatherette-covered foam cushions and a stainless steel frame rated for daily commercial use from -10°C to 55°C.
Certified, Supported and Warranted in Singapore
This variant is certified for Microsoft Teams, with a dedicated Teams button for instant access to meetings and notifications, and works equally well with Zoom, Google Meet, Cisco Webex and Amazon Chime. Deployed at scale, the Evolve2 50 is managed through Jabra Direct for individual firmware and device settings and Jabra Xpress for mass deployment across a fleet. Every unit sold by SourceIT Pte Ltd ships with 2 years local Singapore warranty and a GST invoice, supported locally rather than through an overseas RMA queue.

Frequently Asked Questions — Jabra Evolve2 50
What is the difference between the MS and UC versions of the Evolve2 50?
The MS variant (part numbers 25089-899-xxx and 25089-999-xxx) is certified for Microsoft Teams and carries a dedicated Teams button. The UC variant (25089-889-xxx and 25089-989-xxx) is optimised for all leading UC platforms including Zoom, Google Meet and Cisco Webex. The hardware is otherwise identical — buy MS if Teams is your primary platform, UC if it is not.
Should I choose Mono or Stereo?
Mono covers one ear (99 g) and keeps you aware of the room, which suits contact centres and shared desks. Stereo covers both ears (148.9 g) and, combined with Active Noise Cancellation, gives far better focus in an open-plan office and better music playback. Both share the same microphone boom arm and busylight.
Does the Evolve2 50 have a battery, and how long does it last?
There is no battery to manage. The Evolve2 50 is a wired headset powered over USB from your computer, so it never needs charging and can never run flat mid-call. Its Bluetooth 5.2 radio is used to connect a mobile phone while the headset is plugged in — it is not a standalone wireless headset. If you need true cordless freedom, look at the Jabra Evolve2 55 or Jabra Evolve2 65.
How is the Evolve2 50 different from the Evolve2 40 SE?
The Evolve2 40 SE is the value wired option: same Evolve2 comfort and busylight, but passive noise isolation only and no Bluetooth. The Evolve2 50 adds true Active Noise Cancellation, three microphones and Bluetooth 5.2 dual connectivity to a mobile. Choose the 40 SE for volume rollouts on a budget and the 50 where noise control and mobile pairing matter.
Can I pair it to my phone and my laptop at the same time?
Yes. The USB cable handles the computer connection while Bluetooth handles the phone, giving you both at once. The headset remembers up to 8 paired Bluetooth devices, with one active Bluetooth connection at a time alongside the USB link, at a range of up to 30 m.
Does it come with local warranty in Singapore?
Yes. Every Evolve2 50 sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
