How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the safer long-term buy with a real 12-month replacement guarantee, choose Yrcxtxjy USB C Headphones; if you need metal-bodied earbuds with a larger 10 mm driver and a low-latency 0.01 ms claim, choose SoFunMoky USB C Headphones.
• Yrcxtxjy's biggest strength: a 12-month worry-free new replacement plus 7×24 online support — that's an unusually concrete after-sales promise at this tier of wired earbuds.
• Yrcxtxjy's biggest trade-off: the sheet lists only passive noise cancellation, so it blocks sound with fit and seal alone, and it carries a single model number (YC-260426) with no audio specs published.
• SoFunMoky's biggest strength: real audio numbers on the sheet — a 10 mm dynamic driver, 16 ohm impedance, 100 dB sensitivity and a 0.01 ms latency figure — plus a metal-and-plastic shell.
• SoFunMoky's biggest trade-off: noise control is described as sound isolation rather than active or even labelled passive cancellation, and the fit depends on the supplied eartip.
• In my opinion, pick Yrcxtxjy if you want one pair of plain white USB-C earbuds and the comfort of a replacement policy you can actually hold a brand to.
• In my opinion, pick SoFunMoky if you care more about driver size, published audio specs and a metal build than about warranty wording.
• Quick audience map: Yrcxtxjy for the "set it and forget it" buyer; SoFunMoky for the spec-comparing, bass-curious listener.
Yrcxtxjy plays this one straight. It's a white, in-ear, wired USB-C headphone with a built-in microphone and remote control, and passive noise cancellation handled by the eartip seal. There's no Bluetooth, no battery, no charging case — you plug it into a USB-C port and it works. The model number is YC-260426, it ships as a single unit, and the brand positions it as a one-stop wired audio accessory for USB-C phones and tablets.
The part that actually stands out is the service language. Yrcxtxjy promises 7×24 online support, a 12-month worry-free new replacement, and says it tracks each customer's order. Read that carefully: it's a replacement promise, not just a repair window. For a wired earbud that lives in a pocket and gets yanked out of a phone dozens of times a day, that's the kind of coverage that matters more than a spec sheet. Cables fray, one side goes quiet, the inline remote stops registering — and a new pair beats a mystery return process.
Who should skip it? If you're a spec-sheet shopper, this one will frustrate you. Yrcxtxjy publishes no driver size, no impedance, no frequency response and no sensitivity — you're buying on trust and warranty rather than measurements. And if your priority is isolation on a loud train or plane, passive-only cancellation will only get you as far as a good seal allows. Anyone who wants a metal-bodied, more technical-feeling product should keep reading.
SoFunMoky USB C Headphones: Who It's For
SoFunMoky takes the opposite approach: it puts numbers on the page. The S1 is a white in-ear USB-C headphone built around a 10 mm dynamic driver, with 16 ohm impedance, 100 dB sensitivity, a frequency response figure of 20000 KHz as listed, and an audio latency spec of 0.01 milliseconds. The enclosure mixes metal and plastic, and the earpiece shape is described as a circle. It ships with an eartip, weighs 0.02 kg, and includes a 1-year warranty. Controls are push-button: a microphone, volume control and button remote are all part of the package.
Let's translate that into real-world terms. A 10 mm dynamic driver is a genuinely large diaphragm for an in-ear bud, and larger drivers generally move more air — which is why SoFunMoky's listing leans on "bass stereo" language. Low impedance at 16 ohm and high 100 dB sensitivity mean these should be easy to drive: a phone's USB-C port won't have to work hard to get them loud. That's a meaningful practical advantage if you listen at volume on a commute or in a noisy office.
The 0.01 ms latency figure deserves a caveat. On a wired USB-C connection, latency is effectively a non-issue anyway — the number is there to reassure anyone who's been burned by laggy Bluetooth. If you're gaming or watching video where lip-sync matters, wired is already the right answer, and this spec simply confirms it.
The metal-and-plastic shell is a real differentiator too. Metal housings tend to feel more substantial and resist the flexing that eventually kills plastic buds. The trade-off: metal adds a little weight and can feel cold in winter, and a heavier bud needs a good seal to stay put. Noise control here is listed as sound isolation, so again, isolation is about the tip and the fit, not electronics.
Buy SoFunMoky if you want earbuds with published audio specifications, a sturdier build, inline volume buttons and a bass-forward design. Skip it if you want the longest, most explicit replacement policy — that's not where this brand competes.
• Best for peace of mind → Yrcxtxjy USB C Headphones. A 12-month new-replacement promise and 7×24 support beat a spec sheet you can't argue with.
• Best for published audio specs → SoFunMoky USB C Headphones. 10 mm driver, 16 ohm, 100 dB, 0.01 ms latency — it tells you what's inside.
• Best build materials → SoFunMoky USB C Headphones. Metal plus plastic versus an all-plastic white shell.
• Best for bass-forward listening → SoFunMoky USB C Headphones. A 10 mm dynamic driver is the bigger, more air-moving option of the two.
• Best for quiet, simple plug-and-play → Yrcxtxjy USB C Headphones. No fuss, no specs to decode, just a wired USB-C bud with a mic and remote.
• Best for long listening sessions at volume → SoFunMoky USB C Headphones. High sensitivity and low impedance make them easy to drive from a phone.
• Best for buyers who've had earbuds fail early → Yrcxtxjy USB C Headphones. The replacement policy is the whole point of that purchase.
• Best for people who want inline volume buttons → SoFunMoky USB C Headphones. Push-button volume control is explicitly listed; Yrcxtxjy lists a remote but not volume specifically.
In my opinion, I'd buy the SoFunMoky USB C Headphones. The published specs — a 10 mm dynamic driver, 16 ohm impedance, 100 dB sensitivity, a metal-and-plastic shell and inline volume buttons — give me concrete reasons to expect a sturdy, easy-to-drive, bass-capable pair of wired earbuds. The 1-year warranty covers the basics. If after-sales protection is the thing that keeps you up at night, though, Yrcxtxjy's 12-month new-replacement promise is a legitimately stronger safety net, and I wouldn't argue with anyone who picks it for that reason alone. Check the current price on Amazon before you commit, since that's the one variable that can flip this decision.
Both are wired USB-C headphones, so both fit USB-C iPhones. Yrcxtxjy names iPhone 17/17 Pro/16e/15 in its listing; SoFunMoky names iPhone 17/16/15 Pro Max and Samsung series. Either works if your phone has a USB-C port.
Yrcxtxjy publishes no audio specs, so there's nothing to compare. SoFunMoky lists a 10 mm dynamic driver with 16 ohm impedance and 100 dB sensitivity — in my opinion, that's the more promising spec set for bass and volume, but specs aren't a listening test.
Neither is active noise cancelling. Yrcxtxjy uses passive noise cancellation; SoFunMoky uses sound isolation. Both rely on the eartip seal, so fit is what determines how much you actually block out.
Yrcxtxjy offers 12 months of worry-free new replacement plus 7×24 online support. SoFunMoky offers a 1-year warranty. Yrcxtxjy's wording is more specific about replacing rather than repairing, which is why I'd lean that way if coverage is your priority.
