• Sony WH-CH720N biggest strength: Integrated Processor V1 with DSEE, 360 Reality Audio support, app EQ and multipoint — a feature-dense, lightweight over-ear with up to 35 hours of battery and a 10-minute quick charge.
• Sony WH-CH720N biggest trade-off: Active Noise Cancellation is listed as standard ANC rather than a quantified figure, so you're trusting tuning and comfort over a headline cancellation number.
• Edifier W820NB biggest strength: Up to 88 hours of playback (49 hours with ANC on), -49 dB hybrid ANC, LDAC Hi-Res support, Bluetooth 6.1, spatial sound and a foldable, lighter 247 g body.
• Edifier W820NB biggest trade-off: Charge time is about 2 hours rather than minutes, physical push-button controls instead of touch, and it leans on the app for the deepest customization.
• Pick Sony WH-CH720N if you want refined sound processing, voice control, touch controls and a quick top-up charge before you walk out the door.
• Pick Edifier W820NB if you want to charge once and forget it, want the more aggressive cancellation figure, and want headphones that fold into a bag.
The WH-CH720N is the headphone for someone who cares most about how the sound is handled. Sony's Integrated Processor V1 and Digital Sound Enhancement Engine are the backbone here — the pitch is natural vocals, crystal-clear detail and balanced tuning rather than a bass-heavy party sound. On top of that you get 360 Reality Audio, which uses an ear-shape analysis in the Sony | Headphones Connect app to personalize the immersive mix. If you like fiddling with EQ presets to match your taste, this is the kind of headphone that rewards that habit.
Comfort is the other pillar. Sony builds this as a lightweight, ergonomic over-ear with plastic and thermoplastic elastomer materials, and the whole point of that construction is to make the 35 hours of battery life (ANC on) actually usable — long flights, full workdays, back-to-back calls. The quick charge is the practical detail I'd highlight: about 10 minutes of charging is rated for roughly 60 minutes of playback, so a forgotten charge before a commute isn't a disaster.
For calls and connectivity, Sony leans on Precise Voice Pickup Technology, a wind noise reduction structure and beamforming mics, plus multipoint connection, Swift Pair and Fast Pair, button operation and voice control. Bluetooth range is listed at 10 meters, and there's a stereo mini-jack for wired listening.
Edifier W820NB: Who It's For
The W820NB Plus Gen 2 is built around endurance and flexibility. The headline number is up to 88 hours of continuous playback, dropping to 49 hours with ANC engaged — and even that ANC-on figure outlasts most of what you'd compare it to. Fast charging delivers about 15 hours of playback from a 15-minute charge, so the long charge time (roughly 2 hours to full) rarely bites you in practice. If you're the type who resents charging headphones every few days, this is the design brief you want.
Noise cancellation is hybrid, rated at -49 dB, with multiple modes you can flip through using physical buttons. I actually like that choice — push-button controls are unambiguous when you're wearing gloves or walking. The EDIFIER ConneX app adds sport, office and travel modes, EQ presets, and a volume guard that caps your maximum listening level, which is a genuinely thoughtful feature for long sessions.
Audio hardware is a 40 mm titanium-coated dynamic driver with LDAC Hi-Res support and spatial sound, running over Bluetooth 6.1 with multipoint. The 247 g weight and foldable, memory-foam-cushioned design make it a better travel companion than a fixed-frame headphone, and AI-based noise cancellation isolates your voice for calls.
Who should buy it: frequent travelers, students and anyone who wants maximum battery, the deeper cancellation figure, Hi-Res codec support and a compact foldable shape. Who should skip it: people who prefer touch controls, want the shortest possible charge time, or don't want to rely on an app for the best experience.
Side-by-Side: Which Should You Choose?
• Best for battery life → Edifier W820NB. Up to 88 hours (49 with ANC) versus up to 35 hours on the Sony.
• Best for quick top-ups → Sony WH-CH720N. Roughly 10 minutes for about 60 minutes of playback; Edifier's fast charge is 15 minutes for around 15 hours but needs about 2 hours for a full charge.
• Best for sound personalization → Sony WH-CH720N. Processor V1, DSEE, 360 Reality Audio and app EQ give you more tools to shape the sound.
• Best for Hi-Res wireless codec → Edifier W820NB. LDAC support is on the spec sheet; Sony's sheet emphasizes DSEE and 360 Reality Audio instead.
• Best for travel and packing → Edifier W820NB. Foldable and lighter at 247 g; the Sony is the lighter-feeling ergonomic build but isn't described as folding.
• Best for controls → Sony WH-CH720N if you want touch and voice control; Edifier W820NB if you want physical buttons you can feel.
• Best for calls on paper → a tie, leaning Sony. Both use AI/beamforming mic tech, but Sony adds a dedicated wind noise reduction structure.
In my opinion, the Edifier W820NB is the smarter buy for most people hunting the best selling headphones category. The reason is simple: 88 hours of battery, -49 dB hybrid ANC, LDAC, Bluetooth 6.1, spatial sound and a foldable 247 g body cover the widest range of real-world days — commuting, studying, flying — without babysitting a charger. Sony's WH-CH720N is the pick if sound processing, 360 Reality Audio, touch and voice controls and near-instant quick charging matter more to you than raw endurance. Both are strong; the deciding question is whether you value marathon runtime or refined sound tools. Check the current price on Amazon before you commit — that's the only variable this page can't answer for you.
what is the best selling headphones
There's no single universal answer, because "best selling" shifts by category, region and season, and this page doesn't rank products by sales. What I can tell you is that both the Sony WH-CH720N and Edifier W820NB sit in the popular over-ear noise-cancelling segment, and both are widely stocked mainstream models. If you're shopping by popularity alone, look at what a given retailer's own charts show at the moment you buy.
what is the most popular brand of headphones
Sony is one of the most recognized audio brands globally, and Edifier is a well-established audio manufacturer too, so both carry real brand weight. Popularity of a brand doesn't automatically mean a specific model fits you better, though. Compare features: Sony leans on processing and app tuning here, Edifier on battery life, ANC depth and Hi-Res codec support.
That's a moving target and depends entirely on the retailer and the timeframe, so I won't pretend to have a definitive list. In this matchup, the practical split is battery and cancellation depth on the Edifier side versus sound processing, 360 Reality Audio and fast charging on the Sony side. Decide which of those you'd actually use daily.
Is the Sony WH-CH720N or Edifier W820NB better for long flights?
For raw runtime, the Edifier W820NB wins on paper at up to 88 hours (49 with ANC). For a lighter ergonomic fit and a quick 10-minute top-up that adds about an hour of playback, the Sony WH-CH720N is the more forgiving option. Both are over-ear designs with active noise cancellation, so either works — it comes down to whether you prioritize marathon battery or quick-charge convenience.
