How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a portable LDAC headphone amplifier that can drive real over-ear headphones and decodes with a dedicated DAC chip, choose HAA FEE HA10-II; if you need true wireless earbuds with active noise cancelling and all-day battery, choose Anker Soundcore.
• HAA FEE HA10-II — biggest strength: A dedicated ES9038Q2M DAC plus a TPA6120 headphone amp stage with dual ±9V power, pushing 750mW into 32 Ohm and 150mW into 300 Ohm — it's built to actually drive demanding wired headphones over LDAC.
• HAA FEE HA10-II — biggest trade-off: It's an amplifier, not a headphone. There are no drivers, no earpieces, no noise cancelling — you must already own (or buy) a wired headphone or IEM to plug into its 3.5mm output.
• Anker Soundcore — biggest strength: Liberty 4 NC is a complete listening system in your ears: adaptive ANC rated to cut up to 98.5% of noise, 11mm drivers, Hi-Res LDAC, and up to 50 hours total with the case.
• Anker Soundcore — biggest trade-off: Its LDAC and Hi-Res playback live inside a sealed earbud with a 10 Ohm impedance — you can't swap in your own headphones, and the amp stage is whatever Soundcore built in.
• Pick HAA FEE HA10-II if you own good wired headphones and want LDAC wireless freedom without giving up proper amplification.
• Pick Anker Soundcore if you want one small product that does noise cancelling, calls, and long battery out of the box.
The HA10-II is best understood as a bridge. Bluetooth alone can't drive a pair of 300 Ohm studio cans, and a phone's built-in amp rarely does them justice. HAA FEE solves both problems in one aluminum brick: the QCC5215 Bluetooth chip handles LDAC, aptX-HD, aptX, SBC and AAC reception, then feeds a separate ES9038Q2M DAC that decodes independently — Bluetooth only carries the data. After that, an OPA1612 op-amp and a TPA6120 amp IC with dual ±9V rails do the heavy lifting. The numbers back it up: 750mW at 32 Ohm, 150mW at 300 Ohm, 0.007% distortion, and a 102dB signal-to-noise ratio.
Who should buy it: Anyone with a wired headphone collection who wants to cut the cord without downgrading the sound, plus car-audio and MP3-player users who want a clean DAC/amp stage in the chain.
Who should skip it: If you don't own wired headphones, or you want noise cancelling and a microphone for calls, this isn't the product for you — it has no noise control and no built-in mics listed. It's a purist's tool.
Anker Soundcore: Who It's For
The Liberty 4 NC is the opposite philosophy: everything is already inside. Two earbuds, an 11mm custom-tuned dynamic driver per side, and a charging case. Soundcore rates the adaptive ANC at up to 98.5% noise reduction, and Adaptive ANC 2.0 recalculates in real time based on your ear canals and the noise around you. That's the feature you'll notice most on a plane, a train, or a noisy open office — the world gets quieter without you touching anything.
On the audio side, LDAC is here too, and Soundcore claims it moves roughly 3× more data than standard Bluetooth, which is the same underlying idea as the HAA FEE unit: more bits over the air, more detail in the music. Beyond that you get HearID 2.0 for a personalized sound profile, a fully adjustable EQ, and 22 presets if you'd rather not fiddle. Battery is the headline comfort: 10 hours per charge in normal mode, up to 50 hours with the case, dropping to 8 hours and 40 hours respectively with ANC on. A 10-minute charge gets you moving again.
Connectivity is Bluetooth 5.3 with multi-point, quick pairing on Android, and auto play/pause when you remove an earbud. Six beamforming mics with an AI algorithm handle calls. IPX4 water resistance covers sweat and light rain. The whole kit weighs 19g, and the case is plastic with a black finish on the earbuds.
Who should buy it: Commuters, travelers, gym-goers, and anyone who wants one product that handles music, calls, and quiet — with no cables and no extra gear.
Side-by-Side: Which Should You Choose?
• Best for driving wired headphones → HAA FEE HA10-II. 750mW/32 Ohm and 150mW/300 Ohm with a dedicated TPA6120 stage.
• Best for noise cancelling → Anker Soundcore. Up to 98.5% noise reduction with Adaptive ANC 2.0 that reacts to your ears and environment.
• Best for total battery life → Anker Soundcore. Up to 50 hours with the case versus 8–10 hours on the HAA FEE unit.
• Best for headphone flexibility → HAA FEE HA10-II. Supports any 16–300 Ohm headphone or IEM you already own via the 3.5mm output.
• Best for calls and daily wear → Anker Soundcore. Six AI-assisted beamforming mics and IPX4 water resistance.
• Best for pure DAC/amp quality → HAA FEE HA10-II. ES9038Q2M DAC, OPA1612 op-amp, 0.007% distortion, 102dB SNR.
• Best for sound personalization → Anker Soundcore. HearID 2.0, adjustable EQ and 22 presets.
• Best for tossing in a pocket → Anker Soundcore. 19g total versus a 105g aluminum amplifier.
If I had to pick one, I'd take the Anker Soundcore Liberty 4 NC — because for most people, most of the time, it does more of the job with less friction. Noise cancelling, calls, water resistance, and up to 50 hours of battery in a 19g package is hard to argue with, and LDAC is on board for high-resolution streaming.
But if you're the kind of listener who already owns a serious wired headphone and refuses to give up the amp stage, I'd recommend the HAA FEE HA10-II without hesitation. The ES9038Q2M plus TPA6120 combination at 750mW/32 Ohm is a fundamentally different class of amplification than any earbud can offer. Two different buyers, two different answers — and both are honest ones.
what is ldac headphones
LDAC is a Bluetooth audio codec that transfers roughly three times more data than standard Bluetooth, which allows higher-resolution audio to reach your headphones wirelessly. "LDAC headphones" simply means a headphone or audio device that supports it. Both products here support LDAC — the HAA FEE HA10-II as a receiver, the Soundcore Liberty 4 NC as earbuds.
what is ldac support in headphones
It means the device can receive and decode the LDAC codec over Bluetooth, rather than falling back to SBC or AAC. In the HA10-II, LDAC data is passed to a separate ES9038Q2M DAC for decoding. In the Liberty 4 NC, LDAC is handled internally by the earbuds' own electronics.
what is ldac codec in headphones
The LDAC codec is the compression method used to send audio over Bluetooth with less data loss than standard codecs. Support for it appears on both devices in this comparison: the HA10-II lists LDAC, aptX-HD, aptX, SBC and AAC, while the Liberty 4 NC lists Hi-Res wireless audio with LDAC.
