Jabra put its AI microphone in all five Evolve3 headsets. So why do only two of them lose the boom arm?

When I wrote about the Evolve3 85 and 75 losing the boom arm, most of the reaction focused on the design change itself, the sleek boomless look, whether the AI microphone could really replace a mic sitting an inch from your mouth. What got less attention is that the deep neural network behind that microphone isn’t actually locked to those two flagship models. Jabra put the same core technology across the entire Evolve3 line, including the three boom-arm models it added in July. That’s worth its own look, because it changes how you should actually be comparing these five headsets against each other.

What is Jabra ClearVoice, actually?

Jabra ClearVoice is a deep neural network, or DNN, layered on top of the headset’s existing beamforming and voice algorithms. According to Jabra’s own head of new product development, the DNN itself wasn’t built for headsets in the first place. GN’s hearing aid business had been running similar neural network processing for years, and GN’s gaming arm, SteelSeries, already used a version of it on desktop microphones to isolate a gamer’s voice from a noisy room. The Evolve3 series is the first time that technology reached Jabra’s enterprise headset line, trained on 60 million sentences to separate a speaker’s voice from whatever noise is happening around it. That’s a meaningfully different approach from older-style Active Noise Cancellation, which works by physically detecting and countering ambient sound rather than learning to recognize speech patterns.

Is the same DNN in the Evolve3 45, 65, and 65 Flex too?

Yes. When Jabra expanded the Evolve3 line in July 2026 with the 45, 65, and 65 Flex, all three of those boom-arm models shipped with ClearVoice built in, described in Jabra’s own materials as AI-powered deep learning trained on that same 60-million-sentence dataset. That was worth confirming directly rather than assuming, because it would have been easy for Jabra to reserve its newest processing technology for the premium boomless models and sell the AI story only on the 85 and 75. It didn’t. The DNN is standard across the whole family now, not a flagship-only feature.

So what actually changes between the five models?

If the core AI microphone technology is the same everywhere, the real differences sit in the microphone array and the noise cancellation tier layered around it. The Evolve3 45 uses a 3-microphone ClearVoice setup with what Jabra calls essential in-call ANC, built to take the edge off ordinary office chatter rather than aggressively block it. The Evolve3 65 steps up to a 4-microphone adaptive ANC that adjusts dynamically to your surroundings and fit, and the 65 Flex carries a similar 4-microphone adaptive setup with added wind adaptability for people moving between spaces. The 85 and 75 sit at the top with the boomless design and the most refined tuning of the same DNN pipeline. So the honest way to describe the lineup is that Jabra didn’t build one AI headset and four lesser ones. It built one AI microphone technology and then varied the hardware around it, the mic count, the ANC sophistication, and whether there’s a boom arm at all, to hit different price points and use cases — the same tiering logic we saw in the BIZ series and the Engage line before it.

Does it matter that the DNN is now standard, not premium?

It matters for how you should actually be buying these. If someone assumes they need to pay for the 85 or 75 just to get Jabra’s AI voice isolation for Teams transcription or an AI notetaker, that’s not accurate anymore. That capability is already sitting in the 45 at the bottom of the line. Where the extra spend genuinely buys something is in how well the headset performs in a loud, unpredictable environment, and in whether you want the boom arm gone entirely versus a device that still has one to fall back on. That’s a very different buying conversation than “get the expensive one for the AI features,” and it’s the one IT buyers and channel partners should actually be having with their end users — the same value-per-seat thinking behind our headset-versus-chair comparison.

Whichever model you land on, remember that the headset is only half of the experience: firmware and settings live in Jabra’s companion software, which we untangled in Jabra Direct, Sound+, Plus, and Xpress: which one you need. And if you’re choosing for a whole team rather than one desk, our consultation page is a good place to work through which tier fits which role.
