How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the best ANC over-ear headphones with LDAC hi-res audio for travel, commuting and long listening sessions, choose EarFun Wave Pro Active; if you need open-ear clip-on earbuds with LDAC, spatial audio and a secure fit for sports, choose iKF Open Ear Clip-On.
• EarFun Wave Pro Active — biggest strength: up to 80 hours of playtime with ANC off (55 hours with ANC on) plus 45dB QuietSmart 2.0 active noise cancelling with 5 mics, in a foldable over-ear design.
• EarFun Wave Pro Active — biggest trade-off: LDAC and multipoint can't run at the same time due to chip limitations, and LDAC is Android-only, so you'll have to pick one.
• iKF Open Ear Clip-On — biggest strength: an open-ear ear-hook clip design with 60 hours of total playtime, LDAC decoding, 360° head-tracking spatial audio and Bluetooth 6.0.
• iKF Open Ear Clip-On — biggest trade-off: there's no active noise cancelling — just passive sound isolation — so it won't block out a plane cabin or a busy office.
• Who the EarFun is for: anyone who wants to silence the world and listen for days between charges.
• Who the iKF is for: runners, cyclists and gym-goers who want to hear their surroundings while staying clipped in.
The EarFun Wave Pro Active is built around two ideas: quiet and endurance. Its QuietSmart 2.0 active noise cancelling uses 5 microphones to cut external noise by up to 45dB, which is the kind of spec that matters on a flight, a train or an open-plan office. Pair that with 40mm DLC composite dynamic drivers and LDAC support, and you get a wired-grade detail level over Bluetooth — EarFun states LDAC transfers roughly 3x more detail than standard Bluetooth codecs. Just remember LDAC needs an Android device and has to be switched on in the EarFun App.
Battery life is the headline feature here. You get up to 80 hours with ANC off and up to 55 hours with ANC on at 60% volume. A 10-minute quick charge gives you 10 hours of playback, and if you're ever fully out of juice, the 3.5mm AUX port lets you keep listening with a cable. That's a genuinely flexible setup for a long-haul trip or a week of commuting.
The fit is over-ear and adjustable. Memory foam earpads, rotating ear cups and a foldable frame at 266g make it a comfortable daily companion, and the touch controls plus multipoint connection (switch between two devices) round out the package. The trade-off is that multipoint and LDAC can't be enabled together, and EarFun advises staying within 2 meters of your phone when LDAC is on to avoid dropouts.
Buy it if: you want silence on demand, marathon battery life and hi-res LDAC sound from an over-ear design.
Skip it if: you want to hear traffic and surroundings, or you need one pair for both gaming and ANC.
The iKF Open Ear Clip-On (model iKF Air Clip Pro) takes the opposite approach: it doesn't block the world, it clips around your ear and lets it in. The ComfortAIR+ ear hook design is built to reduce pressure and fatigue over hours of wear, and iKF positions it as more comfortable than in-ear buds with better sound than bone conduction. If you've ever had earbuds slip out mid-run or ache after an hour, this is the design solving that problem.
Audio is more serious than the open-ear category usually suggests. A 12mm long-stroke dual-magnet dynamic driver handles LDAC decoding with up to 990kbps hi-res transmission, and there's head-tracking 360° spatial audio that shifts the soundstage as you turn your head. That's a genuinely different listening experience from a standard stereo pair, and it's the feature that makes this set stand out for movies and games.
Battery is 60 hours of total playtime, dropping to 40 hours with head tracking enabled. Bluetooth 6.0 keeps the connection stable, and a 35ms low-latency mode handles the sync problems that usually ruin mobile gaming audio. Calls run through AI ENC dual microphones that suppress wind and background noise. And IPX5 waterproof and dustproof protection means sweat, rain and splashes are fine.
Buy it if: you run, cycle, lift or work outdoors and want music without sealing off your ears.
Skip it if: you fly often or work in a loud office and need active noise cancelling.
Side-by-Side: Which Should You Choose?
• Best for noise cancelling → EarFun Wave Pro Active. 45dB ANC across 5 microphones versus sound isolation only on the iKF.
• Best for workouts and outdoor sports → iKF Open Ear Clip-On. IPX5 sweat and dust protection plus an open-ear clip that keeps you aware of traffic.
• Best for hi-res detail → close call, both support LDAC. The EarFun pairs LDAC with 40mm DLC drivers; the iKF pairs it with a 12mm dual-magnet driver at up to 990kbps.
• Best for gaming and video → iKF Open Ear Clip-On. 35ms low latency and Bluetooth 6.0 beat what the EarFun sheet lists.
• Best for calls → EarFun Wave Pro Active. 5 AI-powered mics with ENC versus a dual-mic ENC setup — more mics doing the work.
• Best for immersive movie audio → iKF Open Ear Clip-On. Head-tracking 360° spatial audio is unique to this pair.
• Best for flights and commuting → EarFun Wave Pro Active. Foldable over-ear design, ANC and a 3.5mm AUX backup cable for in-flight entertainment.
• Best for switching between phone and laptop → EarFun Wave Pro Active. Multipoint connection, though note it disables LDAC while active.
If I could only pick one, I'd buy the EarFun Wave Pro Active. In my opinion, active noise cancelling at 45dB plus up to 80 hours of battery is the combination that covers the most of daily life — commuting, flights, focus work and long listening sessions — and the LDAC support with 40mm drivers means it doesn't sacrifice sound quality to get there. I'd only steer you to the iKF Open Ear Clip-On if your priority is training outdoors with your ears open and you want spatial audio and low-latency gaming on the side. Check the current price on Amazon for both before deciding, since the value math depends on what you're paying today.
what is ldac headphones
LDAC is a high-resolution Bluetooth audio codec that transmits far more data than standard Bluetooth audio. Headphones that support LDAC — like both of these — can receive up to 990kbps of audio data, which is why they're marketed as hi-res. It requires an Android source device to work.
what is ldac support in headphones
LDAC support means the headphones can decode Sony's high-bitrate Bluetooth codec rather than falling back to a lower-quality standard codec. On the EarFun Wave Pro Active, LDAC has to be enabled in the EarFun App and is Android-only; on the iKF, it works alongside the 12mm driver's hi-res decoding.
what is ldac codec in headphones
It's the software layer that compresses and decompresses audio over Bluetooth. LDAC's advantage is bitrate — roughly 3x the detail of standard Bluetooth codecs according to EarFun — which is what lets these headphones reproduce more of the original recording.
what is ldac sony headphones
LDAC was developed by Sony and is now licensed across brands, which is why you'll see it on non-Sony models like the EarFun Wave Pro Active and iKF Open Ear Clip-On. You don't need Sony headphones to get LDAC — you need an Android phone and a compatible pair.
