• Anker Soundcore — biggest strength: Adaptive ANC 2.0 that cancels up to 98.5% of noise, plus LDAC Hi-Res audio with 11mm drivers and up to 50 hours total battery with the case.
• Anker Soundcore — biggest trade-off: It's a traditional in-ear bud, so you're sealing off your ear canal — that means no natural awareness of traffic or announcements, and the open feel just isn't there.
• EarFun Clip 2 — biggest strength: A clip-on open-ear fit with a C-shaped bridge, 12mm titanium driver, LDAC, Bluetooth 6.0, and real-time AI translation across 100+ languages.
• EarFun Clip 2 — biggest trade-off: No active noise cancellation at all, and battery drops from 11 hours to about 6 hours per charge when LDAC is switched on.
• Who each pick is for: Anker Soundcore for commuters, flyers and anyone who wants quiet; EarFun Clip 2 for runners, cyclists and people who hate things stuffed in their ears.
The Anker Soundcore Liberty 4 NC is built around one idea: quiet. Adaptive ANC 2.0 runs real-time calculations and adjusts to your ear canals and your surroundings, and the spec sheet claims noise reduction of up to 98.5%. That's not a small number, and it's paired with a high-sensitivity in-ear sensor, an oversized driver and a noise isolation chamber. In practice, this is the kind of design that makes a difference on a plane, a train or a loud open-plan office. When the environment changes, the cancellation follows.
Sound-wise, it leans on 11mm custom-tuned dynamic drivers, and LDAC transfers roughly three times more data than regular Bluetooth — which matters if you're streaming high-bitrate audio and want the extra detail to actually survive the trip to your ears. You also get HearID 2.0 to build a sound profile for your hearing, full EQ adjustment and 22 presets if you'd rather just pick a flavour. The 6-mic array with an AI algorithm handles calls, and the whole thing is IPX4 water-resistant.
Battery is where it quietly wins: 10 hours on a single charge in normal mode, 50 hours with the case, dropping to 8 hours per charge and 40 total with ANC on. Bluetooth 5.3 brings multipoint so you can hop between phone and laptop, and there's auto play/pause when you take a bud out.
Who should buy it: commuters, frequent flyers, office workers, and anyone who wants their music to block out the world. Who should skip it: if you run outdoors and need to hear traffic, or you simply can't stand the plugged-ear sensation, this isn't the shape for you.
The EarFun Clip 2 goes the opposite direction. It doesn't insert anything into your ear canal at all — a C-shaped bridge clips onto your ear, tested across 20,000+ flexes, with 40° ultra-soft silicone and a 0.5mm nickel-titanium memory wire you can stretch and rotate to fit your shape. Each bud weighs 5.5g. The pitch is zero pressure, and the design backs that up: nothing is pushing into your ear, so a full day of wear doesn't turn into an ache.
Audio comes from a 12mm titanium-composite dynamic driver with a dual-magnetic circuit, and it supports LDAC and Hi-Res Audio certification. There's also EarFun Spatial Stage Technology for a wider 3D soundstage and directional sound tech that keeps music immersive while still letting traffic and announcements through. That's the whole point of the open-ear format, and it's why this thing is aimed squarely at running and commuting.
The extras are genuinely unusual. Real-time AI translation covers 100+ languages through the EarFun Audio App, with both real-time and face-to-face modes. Calls run through 4 mics with AI environmental noise cancellation to pull your voice out of wind and chatter. Bluetooth 6.0 handles the connection, multipoint lets you jump between devices without re-pairing, and Google Fast Pair speeds up setup. Physical buttons mean no accidental touch triggers, and IP55 dust/water resistance covers sweat and rain — though note the charging case isn't protected.
Battery: up to 11 hours per charge and 40 hours with the USB-C case, but LDAC eats into that — you're looking at about 6 hours per charge with it enabled. A 10-minute charge gives 2.5 hours.
Side-by-Side: Which Should You Choose?
• Best for noise cancellation → Anker Soundcore. Up to 98.5% reduction with adaptive ANC 2.0. The EarFun Clip 2 has no ANC at all.
• Best for open-ear awareness → EarFun Clip 2. Directional sound tech keeps you connected to traffic and announcements.
• Best for maximum battery → Anker Soundcore. 50 hours total with the case, or 40 with ANC on.
• Best for long single-charge listening with LDAC on → EarFun Clip 2. Anker doesn't break out an LDAC-specific figure, while EarFun explicitly states about 6 hours per charge with LDAC enabled.
• Best for secure fit during exercise → EarFun Clip 2. The C-bridge, memory wire and 5.5g per bud are designed for movement; IP55 handles sweat and rain.
• Best for calls in noisy places → Anker Soundcore. 6 beamforming mics with AI voice isolation versus EarFun's 4 mics.
• Best for connectivity and device switching → EarFun Clip 2. Bluetooth 6.0, multipoint and Google Fast Pair edge out Bluetooth 5.3.
• Best for travellers who want quiet → Anker Soundcore. IPX4, multipoint and deep noise reduction make it the better flight companion.
In my opinion, the Anker Soundcore Liberty 4 NC is the safer buy for most people. Adaptive noise cancellation is the feature you'll notice every single day, and the 50-hour case battery means you charge it less often. I'd recommend the EarFun Clip 2 specifically if you exercise outdoors, hate the plugged-ear feeling, or want the AI translation feature — it's a genuinely different product, not a lesser one. If you're torn, ask yourself one question: do you want the world muted, or do you want to stay part of it? That answer picks your earbuds.
FAQ
LDAC is a high-resolution Bluetooth audio codec that transfers roughly three times more data than standard Bluetooth, so more of the original recording survives the wireless trip. Both products here support it: the Anker Soundcore Liberty 4 NC with 11mm drivers, and the EarFun Clip 2 with a 12mm titanium-composite driver. You'll need a source device that supports LDAC to take advantage of it.
It's the compression method used to send audio over Bluetooth, and a better codec means less data thrown away before it reaches your ears. LDAC is one of the higher-bitrate options, which is why both of these products pair it with Hi-Res audio claims and larger dynamic drivers. If you mostly stream standard-quality audio, the benefit is smaller than it sounds.
Yes, and it's the biggest one. The Anker Soundcore has adaptive ANC 2.0 with up to 98.5% noise reduction; the EarFun Clip 2 lists noise control as "None" because its open-ear design is meant to let outside sound in. That single difference should drive your choice more than any spec sheet detail.
