• Amazon Renewed Edifier W820NB — biggest strength: Hybrid active noise cancellation rated at -49 dB, LDAC Hi-Res audio, and up to 88 hours of playback (49 hours with ANC on).
• Amazon Renewed Edifier W820NB — biggest trade-off: It is an over-ear headphone at 470 g, it is a renewed unit with a 90-day limited warranty, and there is no wired jack — everything runs over Bluetooth or USB-C.
• EarFun Clip 2 — biggest strength: An open-ear clip-on design at 5.5 g per earbud, IP55 sweat and splash resistance, LDAC, and up to 40 hours total with the charging case.
• EarFun Clip 2 — biggest trade-off: No noise cancellation at all, a shorter 15 m Bluetooth range, and LDAC drops single-charge playtime from 11 hours to about 6 hours.
• Choose Amazon Renewed Edifier W820NB if you want to block out a commute or an office and go days between charges.
• Choose EarFun Clip 2 if you want something that stays put on a run, lets you hear your surroundings, and doubles as a translation tool.
This is a full-size, over-ear headphone built around two ideas: silence and stamina. The hybrid ANC is rated at -49 dB, and there are multiple ANC modes you switch with physical buttons or fine-tune in the EDIFIER ConneX app, including presets aimed at sport, office, and travel. The driver covers a 20Hz–40kHz frequency range, which is the headroom LDAC needs to actually mean something. Spatial sound and custom EQ presets live in the same app, and there is a volume guard that lets you cap your own maximum level — a genuinely useful feature if you tend to creep the volume up on long flights.
Who should buy it: commuters, open-plan office workers, frequent flyers, and anyone who wants LDAC detail without a cable. Who should skip it: runners and cyclists who need to hear traffic, people who dislike the pressure and warmth of over-ear cups, and shoppers who want the safety net of a long manufacturer warranty — this is a renewed unit covered by a 90-day limited warranty, so factor that in. Also note the Smoky Pink finish is a fixed color choice, not a palette. If price matters to you, check the current price on Amazon rather than assuming renewed means cheap.
EarFun Clip 2: Who It's For
The EarFun Clip 2 goes the other way entirely. Each earbud weighs 5.5 g and clips onto the outside of your ear with a C-shaped bridge built from 40° ultra-soft silicone and a 0.5 mm nickel-titanium memory wire. Nothing enters your ear canal, so there is no plugging sensation and no pressure build-up. More importantly, the open design means traffic, announcements, and voices still reach you — which is exactly why this shape has taken over running and cycling.
Sound comes from a 12 mm titanium-composite dynamic driver with a dual-magnetic circuit, and LDAC plus Hi-Res Audio certification is on board. EarFun Spatial Stage widens the stage, and Directional Sound Tech keeps your music pointed at you while letting the outside world in. Four microphones with AI noise cancellation handle calls, which matters more than usual here because there is no passive seal to help you.
Battery is up to 11 hours per charge, 40 hours total with the USB-C case, and a 10-minute top-up gives roughly 2.5 hours. Turn LDAC on and single-charge life drops to about 6 hours. Bluetooth 6.0 handles multipoint so you can move between a tablet and a phone without re-pairing, and Google Fast Pair speeds up first setup. IP55 covers sweat, rain, and splashes — the case is not rated, so dry it off. There is also real-time AI translation across 100+ languages through the EarFun Audio App, plus physical buttons that resist accidental presses.
Who should buy it: runners, cyclists, gym-goers, commuters who refuse to be sealed off from the world, and anyone who wants translation on the go. Who should skip it: people who want to silence a noisy train, and anyone who needs all-day single-charge endurance with LDAC active. The 18-month warranty is a meaningful plus over a 90-day renewed term if peace of mind is your priority. Check the current price on Amazon when you compare.
• Best for noise cancellation → Amazon Renewed Edifier W820NB. -49 dB hybrid ANC in multiple modes; the EarFun Clip 2 has no noise control at all.
• Best for battery life → Amazon Renewed Edifier W820NB. Up to 88 hours, or 49 with ANC on, versus 11 hours per charge on the Clip 2.
• Best for running and cycling → EarFun Clip 2. Open-ear, 5.5 g per bud, secure clip, IP55, and you keep your awareness of traffic.
• Best for LDAC listening without interruptions → Amazon Renewed Edifier W820NB. LDAC does not cost you battery the way it does on the Clip 2, which falls to about 6 hours.
• Best for calls in wind and noise → EarFun Clip 2 on paper. Four mics with AI noise cancellation versus the Edifier's AI voice isolation — both target clear calls, but the Clip 2 leans harder on mic count.
• Best for travel and packing → EarFun Clip 2. A case that fits a pocket beats a 470 g foldable headphone, though the Edifier folds flat for a bag.
• Best for warranty confidence → EarFun Clip 2. 18-month warranty versus 90 days limited on the renewed Edifier.
• Best for long-haul flights → Amazon Renewed Edifier W820NB. ANC plus 30 m Bluetooth range and app EQ make it the better cabin companion.
If I had to pick one, I would buy the Amazon Renewed Edifier W820NB — with one condition. In my opinion, the combination of -49 dB ANC, LDAC, and up to 88 hours is simply more headphone for the money, and the 90-day warranty is a risk I would accept for that feature set. But I would only recommend it if you listen indoors, on planes, or in offices. If your listening happens while moving — running, cycling, gym — the EarFun Clip 2 is the one I would actually reach for, because an open-ear clip you forget you are wearing beats a headphone you leave at home.
FAQ
what is ldac headphones
what is ldac codec in headphones
It is Sony-developed Bluetooth audio coding that carries far more data than the baseline SBC codec, which is why it is tied to Hi-Res Audio. In practice, headphones with LDAC can reproduce more of the detail in a high-resolution track. On the EarFun Clip 2, enabling LDAC reduces single-charge playtime to roughly 6 hours; on the Edifier W820NB, battery life stays high.
what is ldac support in headphones
LDAC support means the headphone's Bluetooth chip and driver can handle the codec, and the driver has the frequency headroom to show it. The Edifier W820NB covers 20Hz–40kHz, and the EarFun Clip 2 pairs LDAC with a 12 mm titanium-composite driver. Support alone is not a guarantee of great sound — the driver, fit, and seal do the rest.
what is ldac sony headphones
That phrase usually refers to Sony's own LDAC-equipped models, since Sony developed the codec. You do not need Sony hardware to use LDAC, though — the two products compared here are Edifier and EarFun, and both include LDAC support. You do need a phone, player, or transmitter that sends LDAC for it to matter.
