How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want all-day wireless freedom with adaptive noise cancelling and a huge 50-hour battery reserve, choose Anker Soundcore; if you need wired, latency-free HiFi monitoring with a swappable MMCX cable and a built-in mic, choose DCMEKA DEMAKE.
• Anker Soundcore (Space A40) — biggest strength: Adaptive active noise cancelling that claims up to 98% noise reduction, plus 50 hours of total playtime with the case.
• Anker Soundcore — biggest trade-off: It's a wireless Bluetooth 5 earbud with no headphone jack, so sound quality depends on Bluetooth and the LDAC codec rather than a direct wired signal.
• DCMEKA DEMAKE (A09) — biggest strength: Tesla dual dynamic drivers (9.2mm + 6mm) in a wired, semi-transparent IEM shell with a detachable MMCX silver-plated cable.
• DCMEKA DEMAKE — biggest trade-off: It's a wired USB Type-C set with passive noise isolation only — no active noise cancelling and no battery reserve.
• Anker Soundcore is for you if you commute, fly, work in noisy spaces, and want to move around untethered.
• DCMEKA DEMAKE is for you if you're a singer, gamer, or audiophile who wants a cable you can replace and zero wireless lag.
The Space A40 is built around two things: quiet and stamina. Its upgraded noise cancelling system is designed to block a wider range of distracting sounds, and it automatically detects what's around you and adjusts the level — indoors, outdoors, on a commute, or on a flight. That's the kind of set-and-forget convenience that makes a difference when you're moving between environments all day. The fit is pitched as unusually small and light — smaller than Soundcore's other ANC earbuds and described as light as a sheet of paper — which matters if you wear earbuds for hours and normal ones start to ache.
On the sound side, the double-layer diaphragm dynamic drivers are tuned for strong bass, clear mids, and bright treble, and you can switch to LDAC mode for Hi-Res Audio Wireless. LDAC transfers roughly three times more detail than standard Bluetooth codecs, so if your phone supports it, you get a richer signal than a basic wireless connection allows. Battery is the headline: 10 hours on a single charge, up to 50 hours total with the case, and a 10-minute top-up gives you about 4 hours — enough to cover a commute on almost no notice.
Buy it if you want one pair for the gym, the train, the office, and the plane without ever thinking about cables. Skip it if you need a wired connection, a detachable cable you can upgrade, or genuinely zero-latency monitoring — Bluetooth, even with LDAC, isn't that.
The DEMAKE A09 is a different animal entirely. It's a wired in-ear monitor with a USB Type-C connection, and its reason for existing is the driver setup: Tesla dual dynamic drivers at 9.2mm + 6mm, tuned for deep bass, rich mids, and crisp highs. Impedance is 32 ohms with 112 dB sensitivity, so it's easy to drive from a phone, a laptop, or a small DAC without needing serious amplification. The semi-transparent black shell isn't just for looks — it's an ergonomic in-ear monitor structure that seats deep and gives you effective passive noise isolation.
The MMCX detachable cable is the feature that separates it from throwaway earbuds. You can swap or upgrade the cable, and the connector is rated for repeated plugging and unplugging, which extends the life of the whole set rather than forcing you to replace it when a wire frays. The included cable is a 5-foot, four-strand braided silver-plated design, and it ships with a built-in high-definition microphone and inline controls for calls, pausing, and track skipping. You also get a carry case and multiple ear tip sizes (S/M/L). It's water-resistant for workouts and light rain, but not waterproof.
Buy it if you want wired reliability, replaceable parts, and a sound signature aimed at singers, gamers, and audiophiles. Skip it if you want active noise cancelling, wireless freedom, or a battery that lets you leave the cable at home. Note it's a 3.5mm-style wired set in spirit, but the listed jack is USB Type-C — devices without that port need an adapter, which isn't included.
• Best for noise cancelling → Anker Soundcore. Adaptive ANC claiming up to 98% reduction versus DCMEKA's passive isolation only.
• Best for battery life → Anker Soundcore. 10 hours per charge, 50 hours total with the case, plus a 10-minute fast charge for 4 hours.
• Best for wired, zero-latency monitoring → DCMEKA DEMAKE. A direct USB Type-C connection with no Bluetooth delay.
• Best for repairability and upgrades → DCMEKA DEMAKE. The MMCX detachable cable lets you replace or upgrade the wire instead of the whole set.
• Best for commuting, flights, and open offices → Anker Soundcore. Auto-adjusting ANC and a small, light fit are made for all-day wear in loud places.
• Best for singers and stage/gaming use → DCMEKA DEMAKE. Dual dynamic drivers, a semi-transparent IEM shell, and inline controls suit monitoring and play.
• Best for Hi-Res wireless listening → Anker Soundcore. LDAC mode carries roughly three times more detail than standard Bluetooth codecs.
• Best for portability and cable-free workouts → Anker Soundcore. The charging case and water-resistant DCMEKA set both travel well, but only one has no cable at all.
In my opinion, the Anker Soundcore Space A40 is the safer buy for most people. Adaptive ANC, a 50-hour reserve, LDAC, and a fit designed to disappear in your ears cover the widest range of everyday situations — commuting, working, flying, training. I'd only steer you to the DCMEKA DEMAKE if you specifically want a wired IEM: a detachable MMCX cable, a built-in mic, and dual dynamic drivers you can drive straight from a USB Type-C device. If your priority is silence and battery, go Soundcore. If your priority is a cable you can replace and a wired signal, go DCMEKA.
Anker Soundcore. It uses active noise cancelling that adapts to your surroundings and claims up to 98% noise reduction. DCMEKA DEMAKE relies on passive isolation from its in-ear seal, which blocks some sound but not engine drone or office hum the way ANC does.
They connect via USB Type-C, so a phone or laptop with that port works directly. For other devices you'd need an earphone adapter, which isn't included. If you want purely wireless, the Anker Soundcore is the pick instead.
Both can work, but differently. The DCMEKA set is water-resistant (not waterproof), so it handles sweat and light rain. The Anker Soundcore is cable-free, which is a real advantage when you're moving — no wire to snag.
Only on the DCMEKA DEMAKE. Its MMCX detachable cable is designed for replacement and upgrades, which extends the set's lifespan. The Anker Soundcore is a sealed wireless earbud, so there's nothing to swap.
