If you want active noise cancellation that actually quiets a plane, train or open office, choose Anker Soundcore; if you need an open-ear clip design that keeps you aware of traffic and stays put through a run, choose EarFun Clip Open Ear. Both support LDAC, both run 10 hours per charge, and both stretch to 40–50 hours with the case. The difference is philosophy: one shuts the world out, the other lets it in.
• Anker Soundcore — biggest strength: Adaptive ANC that reduces up to 98.5% of noise, plus a 50-hour total battery figure and a fully tunable sound via HearID 2.0.
• Anker Soundcore — biggest trade-off: It's an in-ear design with IPX4, so it seals your ears and stays splash-resistant rather than sweat-proof, and there's no dedicated app-free button control story — it's touch.
• EarFun Clip Open Ear — biggest strength: A clip-on open-ear shape that never blocks your ear canal, with IP55 water resistance and Bluetooth 6.0.
• EarFun Clip Open Ear — biggest trade-off: No noise cancelling at all — that's the point of the design — and it's heavier at 49 g versus 19 g.
• Who the Anker pick is for: commuters, flyers and anyone who wants quiet.
• Who the EarFun pick is for: runners, cyclists and gym-goers who need to hear what's around them.
The Soundcore by Anker Liberty 4 NC is built around one job: making the world quieter. Its high-sensitivity in-ear sensor, oversized driver and noise isolation chamber are rated to cancel up to 98.5% of noise, and Adaptive ANC 2.0 recalculates in real time based on your ear canals and what's happening around you. On a noisy commute or a flight, that's the feature you'll notice every single time you put them in.
For sound, you get 11mm custom-tuned dynamic drivers and LDAC, which transfers roughly 3× more data than standard Bluetooth — the same Hi-Res wireless angle the EarFun shares. Where Anker pulls ahead on personalization is HearID 2.0, which maps a sound profile to your hearing, plus 22 EQ presets if you'd rather just pick one. Battery lands at 10 hours per charge and 50 hours with the case in normal mode, dropping to 8 and 40 with ANC on. Bluetooth 5.3 brings multipoint, auto play/pause on wear, and fast pairing with Android.
Who should skip it? If you run outdoors and need to hear cars, or if you simply can't stand anything sealed in your ear canal, this isn't the shape for you. IPX4 handles rain and splashes, not heavy sweat sessions.
The EarFun Clip is the opposite bet. Instead of sealing your ear, it clips over it using a C-shaped bridge and 0.55 titanium memory wire wrapped in soft liquid silicone. EarFun says the shape came out of 20,000+ flex tests and months of real-person wear data, and the goal is zero pressure and no fatigue over a full day. In practice, that's the appeal: you forget they're there, and you can still hear your surroundings.
Sound comes from 10.8mm custom carbon drivers with LDAC and Hi-Res audio support, and Directional Sound Tech aims the audio at you while limiting leakage. Bluetooth 6.0 is the newer standard here, with dual-device multipoint and Google Fast Pair for Android. Dual mics with AI noise cancellation handle calls. Playtime is 10 hours per charge and 40 hours with the case, and a 10-minute top-up gets you 2.5 hours — handy before a workout. IP55 means it shrugs off sweat and rain far better than a splash rating.
The trade-off is honest: there is no noise cancelling, because open-ear design can't seal out the world. If you want silence on a plane, this is the wrong tool. It's also the heavier of the two at 49 g, and it uses physical buttons rather than touch — which I actually prefer mid-run, since there's no accidental tap to worry about.
Side-by-Side: Which Should You Choose?
• Best for situational awareness → EarFun Clip Open Ear. Open-ear clip design keeps traffic and voices audible while you listen.
• Best for total battery life → Anker Soundcore. 50 hours with the case in normal mode versus 40 hours for the EarFun.
• Best for workouts and sweat → EarFun Clip Open Ear. IP55 versus IPX4 on the Anker.
• Best for sound personalization → Anker Soundcore. HearID 2.0 plus 22 EQ presets and full manual EQ.
• Best for Android pairing → EarFun Clip Open Ear. Bluetooth 6.0 with Google Fast Pair and dual-device multipoint.
• Best for call clarity in wind → EarFun Clip Open Ear. Dual mics with AI environmental noise cancellation; the Anker counters with 6 beamforming mics and its own AI algorithm.
• Best for all-day comfort without ear pressure → EarFun Clip Open Ear. No seal, no in-ear fatigue.
• Best for touch controls and wireless charging convenience → Anker Soundcore. Touch control plus a charging case; the EarFun uses physical buttons and USB-C.
If I had to pick one, I'd buy the Anker Soundcore Liberty 4 NC for commuting, travel and focused listening, because noise cancelling is the feature that changes your day the most when you're surrounded by noise. I'd recommend the EarFun Clip Open Ear the moment your priority shifts to running, cycling or gym work where hearing your environment matters more than blocking it. Two different jobs, two different answers — pick the job you actually have.
what is ldac headphones
LDAC is a high-quality Bluetooth audio codec that transfers roughly three times more data than standard Bluetooth, so supported headphones can receive near-Hi-Res wireless audio. Both products here support it, which means you get the same high-bitrate ceiling on either one.
what is ldac codec in headphones
It's the encoding standard that sits between your phone and your earbuds. When both ends support LDAC, the audio stream carries more detail than a basic Bluetooth connection, which is why both the Liberty 4 NC and the EarFun Clip advertise Hi-Res wireless audio.
what is ldac support in headphones
It means the headphones can decode an LDAC stream, so a compatible Android device can send higher-quality audio. The catch is that both your phone and the earbuds need to support it for the benefit to show up.
which one sounds better, Anker Soundcore or EarFun Clip Open Ear
Both use LDAC and Hi-Res audio, so the real difference is tuning and fit. The Anker pairs 11mm drivers with HearID 2.0 and 22 EQ presets for a sealed, detailed listen; the EarFun uses 10.8mm carbon drivers with Directional Sound Tech for an open, aware sound. In my opinion, the Anker wins for critical listening and the EarFun wins for outdoor use.
