If you want maximum battery life and an over-ear design that can also run wired, choose Amazon Renewed Edifier W80; if you need compact in-ear buds with stronger noise cancelling and water resistance for workouts, choose EarFun Air Pro 4i.
• Amazon Renewed Edifier W80 — biggest strength: up to 65 hours of wireless playback on a single charge, plus a 3.5 mm jack so you can go wired when the battery runs out.
• Amazon Renewed Edifier W80 — biggest trade-off: it's an over-ear headphone with no water-resistance rating, and as a Renewed item it carries a 90-day limited warranty instead of a full-length new-product one.
• EarFun Air Pro 4i — biggest strength: adaptive hybrid ANC rated up to 50dB, IP55 water and dust resistance, and an 18-month warranty in a pocket-sized charging case.
• EarFun Air Pro 4i — biggest trade-off: total battery life tops out at 40 hours with the case, and it drops to around 27 hours with ANC switched on.
• Pick the Edifier W80 if you want long listening sessions at a desk, on a plane or on the couch and value over-ear comfort plus a wired fallback.
• Pick the EarFun Air Pro 4i if you want something small, sweat-friendly and aggressively noise-cancelling for commuting, gym time and calls on the move.
The W80 is built around endurance. Edifier rates it at up to 65 hours of wireless playback, and a 15-minute fast charge adds roughly 10 more hours. That's the kind of number that matters if you're the person who forgets to plug things in, or who wears headphones through a full workday and then some. The 40mm dynamic driver with a titanium-coated diaphragm is the core of the sound, and with LDAC on board you're getting Hi-Res wireless audio rather than a compressed-only stream.
Noise cancelling is hybrid ANC with over-ear passive isolation, rated to cut background noise by up to -49dB. Because the ear cups physically cover your ears, passive blocking does part of the job before the electronics even kick in. Ambient Sound Mode lets you dial in how much of the outside world you want back, adjustable through the app, which is handy for crossing a street or catching a gate announcement.
Comfort is clearly a design priority: memory foam pads wrapped in leather, a spacious ear cup, and a silent hinge that Edifier says minimizes vibration noise. It folds for storage, runs Bluetooth 5.4, and can hold two devices at once for multipoint switching. There's also a 3.5 mm jack, so you can plug in and keep listening with zero battery involved.
EarFun Air Pro 4i: Who It's For
The Air Pro 4i goes the other direction: small, sealed and adaptable. Adaptive hybrid ANC adjusts cancellation based on your surroundings, rated up to 50dB — a higher figure than the Edifier's -49dB, and because these are in-ear buds, the seal in your ear canal adds its own passive blocking. Six AI-enhanced ENC microphones handle voice pickup, which is a lot of mic hardware aimed squarely at making calls sound clean when you're somewhere noisy.
Sound comes from an 11mm custom dynamic driver with LDAC support and a 3D surround sound mode. The frequency range runs 20 Hz to 20,000 Hz at 32 ohm impedance, which is a standard full-range tuning on paper. The EarFun App lets you adjust EQ, cycle noise-cancelling modes and remap the touch controls, so the tuning isn't fixed if the default doesn't suit you.
Battery is 9.5 hours per charge and 40 hours total in normal mode, dropping to 6.5 hours and 27 hours with ANC on. A five-minute top-up gives about two hours of play. Bluetooth 5.4 handles multipoint across two devices, and Google Fast Pair makes Android setup quick. IP55 water and dust resistance means sweat and light rain aren't a problem, and the 18-month warranty is a meaningful cushion compared with the Renewed Edifier's 90 days.
Who should buy it: commuters, gym users, runners, cyclists, and anyone who takes a lot of calls while moving. Who should skip it: people who dislike things inside their ears, want a wired option, or need more than roughly 9.5 hours before reaching for the case.
• Best for battery life → Amazon Renewed Edifier W80. Up to 65 hours wireless versus 40 hours total for the EarFun with its case.
• Best for noise cancelling → EarFun Air Pro 4i. Adaptive hybrid ANC rated up to 50dB, with in-ear sealing adding extra isolation.
• Best for comfort over long sessions → Amazon Renewed Edifier W80. Memory foam pads, leather covering and a spacious over-ear cup instead of a nozzle in your ear canal.
• Best for workouts and weather → EarFun Air Pro 4i. IP55 water and dust resistance; the Edifier has no IP rating listed.
• Best for wired listening → Amazon Renewed Edifier W80. It has a 3.5 mm jack; the EarFun has no jack at all.
• Best for portability → EarFun Air Pro 4i. In-ear buds plus a charging case versus a full-size folding headphone.
• Best for call clarity on the move → EarFun Air Pro 4i. Six AI-enhanced ENC mics with adaptive ANC behind them.
• Best for warranty peace of mind → EarFun Air Pro 4i. 18 months from EarFun versus a 90-day limited warranty on the Renewed Edifier.
• Best for Hi-Res LDAC listening at a desk → Amazon Renewed Edifier W80. LDAC plus a 40mm titanium-coated dynamic driver in a larger acoustic chamber.
If I had to pick one, I'd take the EarFun Air Pro 4i. In my opinion the combination of adaptive hybrid ANC up to 50dB, IP55 durability, multipoint, LDAC and an 18-month warranty covers more of the situations most people actually listen in — commuting, working out, taking calls — and the case makes it genuinely pocketable. The Edifier W80 is the better choice only if your priority is marathon battery life and over-ear comfort, and you're comfortable with a Renewed unit and a 90-day limited warranty. Both support LDAC and Bluetooth 5.4, so the real decision is form factor and durability, not codec. Check the current price on Amazon before you commit — that's the one number that can tip either way.
FAQ
what is ldac headphones
what is ldac support in headphones
It means the headphones can decode the LDAC codec, which Edifier describes as delivering roughly 3x more detail for a near-lossless wireless experience. The catch is that your phone or player also has to support LDAC for it to activate — otherwise the headphones fall back to a standard codec.
what is ldac codec in headphones
It's the encoding method used to send audio over Bluetooth. In these two products LDAC is paired with real driver hardware — a 40mm titanium-coated dynamic driver in the W80 and an 11mm dynamic driver in the Air Pro 4i — so the codec feeds a proper acoustic system rather than a tiny budget driver.
what is ldac sony headphones
LDAC was developed by Sony and is now used across many brands, including Edifier and EarFun. You don't need Sony headphones to use LDAC — you need a source device that supports the codec and headphones that decode it, which both of these do.
