If you want the more versatile all-rounder with adaptive noise cancelling, spatial sound and a wired fallback, choose JBL Live 670NC; if you need maximum battery life, stronger rated noise cancellation and hi-res LDAC audio in a lighter over-ear build, choose Edifier W820NB.
• JBL Live 670NC — biggest strength: True Adaptive ANC with Smart Ambient, JBL Spatial Sound from 40mm drivers, and a 3.5mm jack so you can keep listening wired when the battery runs out.
• JBL Live 670NC — biggest trade-off: It's an on-ear design, which most people find less isolating and less cushioned for long sessions than an over-ear, and it's the heavier of the two at 0.42 kg.
• Edifier W820NB — biggest strength: Up to 88 hours of playback (49 with ANC on), a rated -49 dB hybrid ANC system, LDAC hi-res audio and Bluetooth 6.1 with multipoint — in a 247 g over-ear package.
• Edifier W820NB — biggest trade-off: No analog jack — USB-C only for wired listening — so you need a USB-C source, and the control scheme is physical buttons rather than the voice/touch approach on the JBL.
• Who the JBL is for: commuters and movie/game watchers who want adaptive noise control that reacts to the room and a cable option for flights or dead-battery moments.
• Who the Edifier is for: travelers, students and work-from-anywhere users who want the longest possible runtime, the deepest rated ANC spec and hi-res codec support.
The JBL Live 670NC is built around flexibility. True Adaptive Noise Cancelling uses noise-sensing mics to adjust in real time rather than sitting at one fixed level, and Smart Ambient does the opposite job — it pipes the outside world in so you can hear a platform announcement or a barista without taking the headphones off. That back-and-forth is the feature you actually notice on a commute, and it's the reason I'd point someone here over a fixed-ANC pair.
Sound-wise, JBL leans on 40mm dynamic drivers with JBL Signature Sound and JBL Spatial Sound, which turns ordinary stereo content into a virtual surround presentation. If you watch a lot of films or play games on a laptop or tablet, that wider soundstage is a genuine quality-of-life upgrade. Add Bluetooth 5.3, multipoint for two devices at once, auto play/pause when you lift the earcups, and tap-to-activate voice assistants, and the feature list reads like a list of small daily conveniences rather than one headline trick.
Battery is the other argument: up to 65 hours with Bluetooth on and ANC off, around 50 hours with ANC running, and a five-minute top-up that buys roughly four hours. A full charge takes about three hours. The 3.5mm jack plus the included detachable audio cable means this pair never truly dies on you — plug into an in-flight entertainment system and keep going.
Edifier W820NB: Who It's For
The Edifier W820NB Plus Gen 2 plays a different game: it goes bigger on the numbers. Hybrid active noise cancellation is rated at -49 dB, and the physical buttons let you cycle ANC levels without touching a phone. The EDIFIER ConneX app adds mode presets for sport, office and travel, plus EQ customization and a volume guard that caps your listening level — a small but genuinely useful feature if you tend to creep the volume up on noisy trains.
Audio is where the Edifier pulls ahead on paper. LDAC support means hi-res wireless streaming on compatible Android devices, and the 40mm titanium-coated dynamic driver covers a 20Hz–20,000Hz range with a 40 ohm impedance. Bluetooth 6.1 with multipoint keeps two devices connected, and the AI-assisted call noise cancellation focuses on isolating your voice from background noise — the part that matters if you take meetings from cafés or a shared apartment.
The headline, though, is endurance: up to 88 hours of continuous use, or about 49 hours with ANC engaged, with a 15-minute charge delivering roughly 15 hours. Full charge takes about two hours. The over-ear, memory-foam-cushioned, foldable design weighs 247 g, which is meaningfully lighter than the JBL, and the over-ear seal is the more isolating of the two shapes. The one real compromise is wired listening — there's a USB-C port but no 3.5mm jack, so analog sources aren't an option.
Buy it if you want the longest battery, the deepest rated ANC and hi-res LDAC in a light over-ear. Skip it if you need a headphone jack, or you'd rather control noise cancelling with taps and voice than buttons.
• Best for battery life → Edifier W820NB. Up to 88 hours (49 with ANC) versus up to 65 hours (about 50 with ANC) on the JBL.
• Best for fast top-ups → Edifier W820NB. 15 minutes of charging gets you roughly 15 hours, against about 4 hours from 5 minutes on the JBL.
• Best for adaptive, hands-free noise control → JBL Live 670NC. True Adaptive ANC adjusts in real time and Smart Ambient lets the world back in.
• Best for the deepest rated noise cancellation → Edifier W820NB. Hybrid ANC rated at -49 dB with switchable levels.
• Best for movies, games and virtual surround → JBL Live 670NC. JBL Spatial Sound expands stereo content into a wider soundstage.
• Best for hi-res wireless audio → Edifier W820NB. LDAC support, which the JBL sheet doesn't list.
• Best for wired listening and analog sources → JBL Live 670NC. It has a 3.5mm jack and a detachable audio cable; the Edifier is USB-C only.
• Best for lighter, more isolating wear → Edifier W820NB. Over-ear cups and 247 g versus the JBL's on-ear fit at 0.42 kg.
• Best for clear calls in noisy places → Edifier W820NB. AI-based voice isolation is the specific claim behind its mic system.
If I were buying one pair for myself and had to pick blind, I'd take the Edifier W820NB. In my opinion the combination of 88-hour battery, a rated -49 dB hybrid ANC system, LDAC hi-res audio and a 247 g over-ear fit covers more of what most people actually do with headphones — commute, work, travel, repeat — without a charging cable in sight.
The JBL Live 670NC is the better pick if your priority is adaptive noise control that reacts to your surroundings, spatial sound for films and games, or a headphone jack you can fall back on. But for the broadest everyday coverage, I'd go Edifier. Check the current price on Amazon before you commit, since that's the one variable a spec sheet can't settle for you.
what is the best selling headphones
There's no single answer, and this page deliberately doesn't rank products by sales. What I can tell you is what makes a headphone sell well: a strong battery claim, effective noise cancelling, multipoint Bluetooth and a comfortable fit. Both the JBL Live 670NC and the Edifier W820NB hit all four, which is why they're the two people most often weigh against each other.
what is the most popular brand of headphones
Popularity varies by region and by category, and neither JBL nor Edifier publishes sales figures here. What's fair to say is that JBL is a long-established audio brand with a wide consumer lineup, while Edifier has built a following around value-focused ANC models. Judge them on the specs that matter to you instead of brand name alone.
Correct. The JBL Live 670NC has a 3.5mm jack and ships with a detachable audio cable, so you can listen wired. The Edifier W820NB Plus Gen 2 lists a USB-C port only, so wired listening requires a USB-C source.
The Edifier W820NB, on paper: up to 88 hours of continuous playback, or around 49 hours with ANC on. The JBL Live 670NC is rated up to 65 hours with Bluetooth on and ANC off, and about 50 hours with ANC engaged. Both support fast charging.
