For calls, my top pick is the TOZO HT3 — the combination of adaptive hybrid ANC, five built-in mics with AI noise reduction, and a dedicated call mic is the most call-focused spec sheet in this group, and the 90-hour battery means you stop thinking about charging.
• TOZO HT3 — best for all-day calling from a desk or a home office; pick this if you want the strongest mic array and battery life in the group.
• TOZO HT3 — best for travel and commuting; pick this if you want the same calling hardware in a different finish with the same foldable, replaceable-pad design.
• JBL Live 670NC — best for hands-free voice assistant control; pick this if you mostly talk to Alexa or Google Assistant and want an on-ear fit.
• JBL Live 670NC — best for movie and gaming nights between calls; pick this if JBL Spatial Sound and auto play/pause matter more to you than maximum battery.
This is an over-ear headphone built around noise cancelling and voice work rather than around a fashion statement. The green finish is the giveaway that TOZO isn't chasing a corporate look here — but the hardware underneath is serious: four high-sensitivity microphones feed the hybrid ANC system, and there's a separate dedicated call mic on top of that. In practice, that split matters. The four mics handle what's coming at you; the call mic handles what you're saying. When you're on a call in a café or an open-plan office, that's the difference between the other person hearing you and the other person hearing the room.
The 45dB adaptive cancellation is the headline number, and it's the one I'd weigh most for calls. Adaptive means the system keeps re-reading your surroundings instead of applying one fixed level of cancellation, so a subway platform and a quiet kitchen don't get treated the same way. AI noise reduction then works on your voice specifically, isolating it and pushing background down. I recommend this one to anyone whose calls happen in unpredictable places — the kind of person who takes a meeting from a train and hopes nobody notices.
Battery is where this pulls away from the pack: up to 90 hours of playback, with a 10-minute quick charge adding around 9 hours. For a call-heavy week, that's the difference between charging every few days and charging once a month. Dual device connection lets you stay paired to a phone and a laptop at the same time and switch between them without re-pairing, which is exactly the workflow a work-from-anywhere caller needs.
The voice assistant support is real and usable — you get hands-free control for music, calls, reminders and general queries, plus AI-powered translation built into the listening experience. Thirty-two EQ presets, 100+ white noise tracks and a library of shared EQs give you room to tune things. The trade-offs are honest ones: 254g is light for an over-ear, but this is still a full-size headphone, not something you'll forget you're wearing. Controls are push-button plus app, so if you prefer pure touch gestures or voice-only control, that's a real adjustment. And 60ms latency is fine for calls and video but not a competitive-gaming figure.
Same headphone, different finish. This version comes in Titanium Blue, and if you're choosing between the two, the decision is essentially cosmetic — the model name, driver, mic count, battery and connectivity story are the same. What I'd flag is that this one is listed with Adaptive Noise Cancellation as the control method, while the green version lists both Active and Hybrid. Functionally you're getting the same adaptive hybrid system; the sheets just describe it at slightly different levels of detail.
For a buyer, that means you pick on color and on nothing else. Both are over-ear with oval earpieces, both use 40mm dynamic drivers, both run Bluetooth 6, both give you a 20-metre wireless range — noticeably longer than the 10 metres the JBL pair offers, which matters if you like to walk away from your laptop mid-call without dropping audio.
The daily-use story is the same too: foldable for bag storage, breathable cushions for long sessions, and removable, replaceable ear pads so hygiene and wear don't end the headphone's life early. Wired listening over 3.5mm AUX or Type-C is there when you're on a plane or the battery is low, and the 32-ohm impedance and 102dB sensitivity mean it'll get loud enough from ordinary phone or laptop output without an amp.
The trade-off is identical to its sibling, and worth repeating: it's a full-size over-ear, so it's a bag item rather than a pocket item. If you specifically want earbuds you can fold into a jeans pocket, neither of these is that product — this is where the best foldable earbuds for calls comparison starts to matter, and it's a different category. And if you're looking for IPX7 waterproof Bluetooth earbuds for calls because you take calls in the rain or at the gym, note that neither TOZO here is rated for water resistance in the specs given; that's a different purchase entirely.
The JBL Live 670NC is an on-ear headphone in Sandstone, and it approaches the voice assistant question from the opposite direction to the TOZO pair. Where TOZO leads with mic hardware, JBL leads with access: you can wake Alexa or Google Assistant either with a hotword or by tapping the earcup. If your calls are mostly "hey, call this person" rather than long conference dial-ins, that tap-to-talk flow is genuinely convenient.
The noise cancelling is True Adaptive, powered by two noise-sensing mics that adjust in real time, and Smart Ambient lets the world back in without you removing the headphones. That's a nice touch for the person who needs to hear a barista or a colleague without breaking their audio. The calling story is decent — four noise-sensing mics total, and JBL specifically calls out wind performance, saying your voice comes through clearly even outdoors in wind. That's a claim worth noting if your calls happen on a walk.
Battery is rated up to 65 hours with ANC off, dropping to 50 hours with Bluetooth and ANC both running. A five-minute charge buys four more hours. That 50-hour figure is the realistic one for a caller using ANC constantly, and it's still a long week. Multipoint keeps two Bluetooth devices connected at once, so you won't miss a call while watching something on a tablet.
The trade-offs are worth being clear about. On-ear means the pads press against your ear rather than around it — some people love the lighter footprint, others find it fatiguing over a multi-hour call block, and it generally seals less than an over-ear design. Bluetooth 5.3 and a 10-metre range are behind the TOZO pair on paper. The 670NC's standout extras — JBL Spatial Sound turning stereo into virtual surround, and auto play/pause when you take them off — are media features, not call features. In my opinion, that makes this the better pick for someone who takes a few calls a day and watches a lot of content, and the weaker pick for someone on calls for six hours straight.
This is the same headphone in Blue. The Blue version is listed with a slightly different enclosure material breakdown and a circular earpiece shape versus the on-ear shape noted on the Sandstone model, plus it ships in a box with cushioning. Neither changes how it sounds or how it handles a call — but there is one connectivity difference worth catching: this listing shows no 3.5mm jack, while the Sandstone version includes a detachable audio cable and a 3.5mm jack.
That matters more than it sounds. If you want a wired fallback for flights, dead-battery moments, or a laptop with an analog output, the Sandstone version is the one that gives you that option. If you'll only ever connect wirelessly, it's a non-issue.
Otherwise, the same reasoning applies: tap or speak to reach Alexa or Google Assistant, True Adaptive ANC with Smart Ambient, multipoint for two devices, 40mm drivers with Spatial Sound, auto play/pause, and the JBL Headphones app for customizing ANC behaviour and sound. Battery is rated the same way — up to 65 hours without ANC, 50 with Bluetooth and ANC on, three hours to a full charge, and a five-minute top-up for four hours of listening.
My honest read: both JBL versions are the more assistant-centric choice, and both TOZO versions are the more call-centric choice. If the phrase "ANC wireless headset for calls" describes what you're after, I'd point you at the TOZO HT3 first. If you want the assistant to be the star and you prefer on-ear, the JBL Live 670NC earns its place.
We compared published specifications and feature sets — microphone count, noise cancelling type, battery ratings, connectivity options, fit style and assistant access — and weighed them against the calling use case this guide is built around. The ordering is our own editorial opinion, not a sponsored placement. No brand paid for inclusion or position, and nothing here is drawn from ratings or sales data.
Yes. The JBL Live 670NC supports Alexa and Google Assistant by hotword or earcup tap. The TOZO HT3 supports hands-free voice control for music, calls and reminders. Both are designed for assistant use; check that your phone's assistant is enabled for the tap or hotword to work.
Over-ear designs like the TOZO HT3 surround the ear and generally seal better, which helps ANC and comfort over long stretches. On-ear designs like the JBL Live 670NC sit against the ear — lighter feeling, but some people find them tiring after several hours.
The TOZO HT3 has 3.5mm AUX and Type-C options. The Sandstone JBL Live 670NC listing includes a detachable audio cable and a 3.5mm jack; the Blue listing shows no jack, so confirm before buying if wired fallback matters to you.
Both the TOZO HT3 and the JBL Live 670NC support dual or multipoint connection, so you can stay paired to a phone and a computer and switch between them without reconnecting.
