Jabra Evolve3 65 Flex: 30-second review
Business headsets have long had something of an image problem. The boom arm shouts “call centre” long before you have said a word. Jabra’s answer, with the Evolve3 range, is to remove it entirely. The Evolve3 65 Flex follows the same recipe as the Evolve3 85, but the emphasis shifts from luxury to portability. It is a foldable, on-ear design that Jabra says slips into the slimmest laptop bag. The headline technology is Jabra ClearVoice, which uses a deep learning system trained on 60 million sentences. It separates your voice from background noise without any visible microphone. Jabra also claims over 95 per cent voice pickup accuracy outdoors, and over 99 per cent in open offices. The adaptive ANC uses four microphones and adjusts to both your surroundings and your fit. Like the Evolve3 85, it keeps working while you are on a call, which remains rare in this class. A 360 degree busylight tells colleagues when to leave you alone. Battery life is where the Flex gives ground. Jabra quotes up to 16. 5 hours of call time and 80 hours of music with ANC off. Fast charging adds up to four hours of music from ten minutes on the cable. The price is lower than the flagship models, but this is still business kit. If your employer is paying, it makes a good case. If you are, you will want to think carefully. [MP: adjust once testing is complete. ]
The Evolve3 65 Flex makes a compelling case on every front except price. But even at this cost, these will most likely be considered for our best Bluetooth headset guide. Jabra Evolve3 65 Flex: price and availability
How much does it cost? From $285/£260/€299
When is it out? Available now
Where can you get it? Direct from Jabra and online retailers
Jabra announced the Evolve3 65 Flex alongside the Evolve3 65 and Evolve3 45 as a cheaper step-down from the Evolve3 85 and Evolve3 75. The recommended price is $389 in the US and €299 in Europe, but the USB-C model for Teams is now $285 directly from Jabra . For comparison, the Evolve3 65 is $300, and the Evolve3 45 is only $199. My review model is part number 36699 999 899, a Microsoft Teams variant with a USB-C Bluetooth adapter. A Teams-certified button sits on the headset, and the box includes a USB-C cable and a carry case, but no Link 390 adapter. The packaging is a plain cardboard box, and the standard package includes no wireless charging pad. Street pricing is already lower than the launch MSRP. Some US resellers list this exact model at the same price as Jabra, and that includes Amazon . European business resellers list the Teams USB-C variant at roughly €190 to €235 before VAT. The review model is £260 from Jabra in the UK, but you can find it on Amazon. co. uk for £219. 99 with next-day delivery. Jabra also offers UC variants for those who don’t use Teams, as well as models with USB-A adapters. Versions bundled with a wireless charging pad cost more. One lure is that Jabra offers free trials to companies with 500 or more employees that are replacing existing devices. The Jabra Plus Management platform handles remote configuration and firmware updates for larger deployments. Individual buyers are less well served. But this headset is aimed at the corporate ear, like the Evolve3 85 before it. (Image credit: Mark Pickavance) Value score: 3. 5/5

Jabra Evolve3 65 Flex: design
No boom arm
Elegant construction
Easier to carry than the Evolve3 85
Like the Evolve3 85, this headset has no boom arm. Therefore, nothing sticks out towards your mouth, and nobody will assume you work on a helpdesk while wearing them. Instead, you get a slim, minimal headset with angled oval ear cushions. They are covered in leatherette over soft acoustic foam. The headband is recycled stainless steel, wrapped in more foam and leatherette. But where this design diverges from the previous Evolve3 concept is how lightweight these are, making them ideal for anyone travelling for business. At 143g, it is notably lighter than the over-ear Evolve3 85, which I measured at 220g in a previous review. Jabra calls its cushion design Air Comfort, which is corporate speak for being smaller. The Flex part of the name refers to the folding design. The earcups rotate, and the headband collapses, so it sits in the supplied case without taking up much space. But the supplied case is about 60% of the size of the Evolve3 85 case, and neither of these has a pocket, or the room, for even the charging cable. The case holds the headset and a Bluetooth dongle only. (Image credit: Mark Pickavance) On a more positive note, Jabra has also kept the replaceable battery and ear cushions from its bigger models. That matters for longevity, and it sits well with current repair legislation across Europe. Finding it in a headset at this price is still less common than it should be, so keeping the hardware going longer matters. The 360-degree busy light is here too, and it works from every angle, as it saves you from having to announce, loudly, that you are on a call. My review sample was the Teams model, so there is also a specific Teams button on the headset. How headphones have ended up with these opposing standards is a rant for another day, but for those who still think Microsoft has something to offer business, Jabra has you covered. As with the 85 model, these designs seem biased toward right-handed use, but I’m sure left-handers will cope with the four buttons on the right side. The materials are also allegedly more planet-friendly. Jabra says 37 per cent of the headset by weight is recycled or biocircular, and the packaging is FSC certified. It’s interesting how Jabra have managed to take its earlier Evolve3 designs and then make them smaller and lighter, without making them impractical to use. From my perspective, the smaller cushions aren’t as comfortable for long sessions as the larger ones on the Evolve3 85, but they’re fine for shorter periods. That fits well with the smaller battery capacity and reduced running time. Design score: 4. 5/5
Jabra Evolve3 65 Flex: Hardware
Bluetooth 5. 2
Microsoft Teams vs UNC
ClearVoice
Bluetooth 5. 3 with LE Audio forms the wireless backbone of this equipment. It supports the LC3 codec, along with AAC, SBC and Jabra also lists Auracast support. Not sure why it doesn’t use the 5. 4 version of Bluetooth like its predecessors, but Bluetooth 5. 2 is fine for this use case. The Link 390 adapter in the box gives a secure, low-latency connection to a PC. Or, you can also connect directly over Bluetooth if you prefer…
