PRODUCT DESCRIPTION
Jabra Evolve2 85 MS Stereo ANC Wireless BT Headset USB-A (28599-999-999) - 2 Years Local Warranty
Jabra Evolve2 85 Specifications at a Glance — 10-Microphone Over-Ear ANC Flagship
The Jabra Evolve2 85 (28599-999-999) is the top of the Jabra Evolve2 range: ten microphones (four analog MEMS and six digital MEMS), 40 mm speakers, and digital hybrid Active Noise Cancellation driven by four dedicated microphones. It is a genuine over-ear design with deep, fully enclosing ear cushions, built for Singapore professionals who need to shut out an open-plan floor and still be heard clearly on every call.
Digital Hybrid ANC and HearThrough in a Fully Enclosing Over-Ear Design
Four of the ten microphones drive Jabra's digital hybrid Active Noise Cancellation, working alongside the passive isolation of the over-the-ear cushions to cut both the low-frequency hum of air-conditioning and the mid-range chatter of a busy office. HearThrough uses the same built-in microphones to let the room back in when you need it, without lifting the headset off. Jabra SafeTone protects hearing over long shifts.
Up to 37 Hours of Music and 26 Hours of Talk Time
Music time runs up to 37 hours with ANC off and up to 32 hours with ANC on. Talk time reaches up to 26 hours with ANC and busylight off, or up to 21 hours with both engaged. A full charge takes up to 140 minutes, with roughly 30% of capacity back in 30 minutes and 60% in 60 minutes.
360° Busylight, On-Head Detection and a Wired 3.5 mm Fallback
A 360° busylight on both earcups is visible from every angle and lights automatically during calls — and only when the headset is actually being worn, so it never signals falsely from your desk. On-head detection auto-pauses music and handles mute when you lift the headset off. Alongside Bluetooth and the included adapter, a 1.2 m 3.5 mm audio cable ships in the box for wired use on aircraft or with legacy equipment. The earcups fold flat into the supplied carry case.
Certified Connectivity: Certified for Microsoft Teams
This part number is a Microsoft Teams certified (MS) build with a dedicated Teams button, and it meets Microsoft Teams Open Office requirements. The included Jabra Link 390a Bluetooth adapter (USB-A) gives a plug-and-play link to a laptop while Bluetooth 5.0 pairs a mobile at the same time — two simultaneous connections from up to eight paired devices, at a range of up to 30 m.

Frequently Asked Questions — Jabra Evolve2 85
What is the difference between the Evolve2 85 UC and MS variants?
The hardware is identical. The MS part numbers (28599-999-xxx) are certified for Microsoft Teams, meet Microsoft Teams Open Office requirements and carry a dedicated Teams button. The UC part numbers (28599-989-xxx) are certified for Alcatel-Lucent, Amazon Chime, Cisco, Google Meet, Mitel and Unify. Order the MS variant if Teams is your primary calling platform.
Is the Evolve2 85 over-ear or on-ear, and is there a mono version?
Jabra classifies the Evolve2 85 as an over-the-ear headband design — the cushions fully enclose the ear, which is what gives it stronger passive isolation than the on-ear Evolve2 65 and Evolve2 75. There is no mono version; the Evolve2 85 is stereo only. For a single-ear headset see the Evolve2 65 UC Mono.
How does the Evolve2 85 compare with the Evolve2 75?
The Evolve2 75 has eight microphones, Jabra Advanced ANC with 11 adjustable settings, Bluetooth 5.2 and an on-ear fit at 197 g. The Evolve2 85 has ten microphones, a fully enclosing over-ear fit, a longer 37-hour music runtime and a 3.5 mm wired option, at 286 g. Choose the Evolve2 85 for maximum isolation at a fixed desk, and the Evolve2 75 if you want a lighter headset with newer Bluetooth and finer ANC control.
What battery life should I expect, and how long does charging take?
Up to 37 hours of music with ANC off and 32 hours with ANC on; up to 26 hours of talk time with ANC and busylight off, or 21 hours with both on. A full charge takes up to 140 minutes, with roughly 30% of capacity back after 30 minutes. The desk stand is not included with this part number and can be ordered separately.
Can I connect to a laptop and a mobile phone at the same time?
Yes. The Evolve2 85 supports multipoint with two simultaneous connections from up to eight paired devices — typically the included Jabra Link 390a Bluetooth adapter (USB-A) in the laptop plus a direct Bluetooth 5.0 pairing to a mobile, with up to 30 m of range. It can also run wired from the 3.5 mm cable when Bluetooth is not permitted.
Which Bluetooth adapter ships with the Evolve2 85?
Current production ships the Jabra Link 390 (390a for USB-A part numbers, 390c for USB-C), per Jabra's Rev E technical specifications. Earlier stock shipped the Link 380, and several Jabra web pages have not yet been updated from the older figure; both adapters work with the headset.
Does SourceIT provide local warranty for the Evolve2 85?
Yes. Every Evolve2 85 sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
