• JBL Live 670NC — biggest strength: True Adaptive ANC with Smart Ambient, JBL Spatial Sound from 40mm drivers, multipoint pairing and a 65-hour battery (50 hours with ANC on).
• JBL Live 670NC — biggest trade-off: On-ear rather than over-ear fit, 32 ohm / 98 dB tuning that's clearly voiced for loud, energetic listening, and a heavier reliance on the JBL app to unlock all its features.
• Anjetsun Headphones — biggest strength: Up to 80 hours of playtime (50–60 with ANC on), a full over-ear oval cup fit, Bluetooth 5.4 and magnetic ear pads you can swap out yourself.
• Anjetsun Headphones — biggest trade-off: Lower sensitivity (25 dB) suggests it needs more power to get loud, no wired 3.5mm fallback, and touch-only controls with no app ecosystem mentioned.
• Who each is for: JBL Live 670NC for the commuter or student who wants adaptive ANC, surround-style spatial audio and brand-name tuning; Anjetsun Headphones for the work-from-anywhere buyer who wants marathon battery, over-ear comfort and user-replaceable pads.
The JBL Live 670NC is built around flexibility. True Adaptive Noise Cancelling uses multiple noise-sensing mics and adjusts in real time, so it reacts to whatever environment you're in rather than running one fixed level of cancellation. Smart Ambient does the opposite job — it pipes the outside world back in so you can hear a platform announcement or a barista without taking the headphones off. For anyone who moves between a noisy train, a quiet library and a shared office in the same day, that combination is genuinely useful.
The feature list doesn't stop there. JBL Spatial Sound turns ordinary stereo into a virtual surround presentation, which is the kind of thing that makes a film or a game feel wider than the 40mm drivers would otherwise suggest. Multipoint Bluetooth 5.3 lets you stay connected to two devices at once, so a call can interrupt a movie without you scrambling for your phone. Auto play/pause stops the music when you lift the headphones off and resumes when you put them back. There's a 3.5mm jack for wired listening, a detachable audio cable in the box, and voice assistant access by tap or hotword.
Who should buy it: the commuter, student or remote worker who values adaptive noise cancelling, app-based customization and a wired backup, and who doesn't mind an on-ear fit. Who should skip it: anyone who specifically wants cups that fully surround the ear, or who wants the absolute maximum hours per charge — the 65-hour figure drops to 50 with ANC running, which is still strong but not the longest here. I'd also flag that the on-ear, plastic-enclosed design sits against the ear rather than over it, which some people find less isolating over long sessions than a full over-ear cup.
The Anjetsun Headphones take a different route: maximum endurance and everyday practicality. The headline number is up to 80 hours with ANC off and 50–60 hours with it on — enough that charging becomes a weekly chore rather than a daily one. If you wear headphones through a full workday, then through an evening of podcasts, that gap matters more than almost any other spec.
The fit is over-ear with oval-shaped cups, soft PU leather cushions and an adjustable headband — the kind of setup people generally reach for when they want something that sits around the ear for hours. The detail I like most is the detachable magnetic ear pads. Ear cushions are usually the first thing to wear out on any headphone, and being able to pull them off and replace them extends the usable life of the product considerably. The package also includes a protective bag.
On the tech side you get Bluetooth 5.4 — the newer standard of the two here — plus a built-in mic and touch controls on the ear cup for play, pause, volume and calls. ANC is on board to cut ambient noise in offices, cafés and on commutes. There's no 3.5mm jack, so this is a wireless-only headphone, and the 25 dB sensitivity rating is notably lower than the JBL's 98 dB, which tells you it will likely need more volume headroom from your source to reach the same loudness.
Who should buy it: the long-session user — remote workers, students in online classes, travellers on multi-day trips — who wants over-ear comfort, replaceable pads and the longest battery in this comparison. Who should skip it: anyone who needs a wired option, or who prefers app-based tuning and a wider feature ecosystem, since the Anjetsun kit is refreshingly simple: cable, magnetic pads, bag, manual.
Side-by-Side: Which Should You Choose?
• Best for battery life → Anjetsun Headphones. Up to 80 hours with ANC off and 50–60 with ANC on beats the JBL's 50 hours with ANC engaged.
• Best for adaptive noise cancelling → JBL Live 670NC. True Adaptive ANC adjusts in real time, and Smart Ambient lets sound back in without removing the headphones.
• Best for multi-device juggling → JBL Live 670NC. Multipoint keeps two Bluetooth devices connected at once, so calls and media don't fight each other.
• Best for wired fallback → JBL Live 670NC. It has a 3.5mm jack and a detachable audio cable; the Anjetsun has no jack at all.
• Best for long-wear comfort and repairability → Anjetsun Headphones. Over-ear oval cups with PU leather and magnetic, replaceable ear pads.
• Best for newer wireless standard → Anjetsun Headphones. Bluetooth 5.4 versus the JBL's 5.3.
• Best for hands-off conveniences → JBL Live 670NC. Auto play/pause, voice assistant activation by tap or hotword, and app-based customization.
In my opinion, the JBL Live 670NC is the better all-rounder and the one I'd buy. Adaptive ANC that reacts to your surroundings, spatial sound, multipoint, a wired backup and app tuning give it more ways to fit into a real day, and 50 hours with ANC on is plenty for most people. I'd only steer you to the Anjetsun Headphones if battery life and over-ear comfort are your top two priorities — its 80-hour ceiling and swappable ear pads are genuinely compelling for all-day, every-day use. Whichever you pick, check the current price on Amazon before deciding, since that's the one variable I can't weigh for you here.
There's no single answer, and I won't pretend otherwise — sales data changes constantly and isn't something this comparison relies on. What I can say is that both of these models are structured to sell well for different reasons: the JBL Live 670NC on its adaptive ANC, spatial sound and multipoint feature set, and the Anjetsun Headphones on its 80-hour battery and replaceable-pad design.
What are the best selling headphones in the world?
I can't give you a definitive ranking, and I wouldn't trust anyone who claims one without citing live sales figures. What's fair to say is that JBL has decades of consumer audio heritage behind it, which gives the Live 670NC a familiarity advantage, while Anjetsun is the newer, spec-forward option for buyers who prioritize battery and fit.
For pure battery endurance and over-ear comfort, yes — 80 hours and replaceable magnetic ear pads are hard to argue with for long workdays. But if your work involves switching between a laptop and a phone, taking calls mid-session, or you want adaptive ANC that adjusts to a changing environment, the JBL Live 670NC's multipoint, True Adaptive ANC and app controls make it the more flexible office companion in my view.
