Inchic EJ-A4

Five pairs of wired earbuds for 3,436 JPY, or about 687 JPY each. The overall score of 19.8 out of 100 and a 7th percentile feature ranking make this one of the weakest products in our database. Buy it for classrooms and kids, not for yourself.

Let's be real: there are no benchmark scores for earbuds like this, and the specs are thin. No frequency response data, no driver size, no impedance rating. What we do know is that the percentile rankings are grim across the board. Connectivity sits at the 9th percentile, which is one of the worst we've seen. Feature set is even lower at the 7th percentile. These are wired 3.5mm earbuds with a basic inline mic and a single button for play/pause, track skip, and call handling. That's the entire feature list.

The button controls are straightforward: one press for play/pause or answer/end call, two presses for next track, three for previous, and a double press to reject a call. The cable is described as tangle-resistant, and the package includes M and L silicone ear tips. The mic is billed as noise-isolating, but without any specs to back that up, we'd treat that claim with a healthy dose of skepticism. For online classes and voice calls, it'll probably get the job done. For music, keep your expectations on the floor.

Stacking the Inchic EJ-A4 against the Apple iPad Pro M5, Samsung Galaxy Tab S11 Ultra, or Microsoft Surface Pro 11 feels almost unfair, but it's useful context. Those are tablets, not earbuds, and they're in completely different leagues on every metric. The iPad Pro M5 and Galaxy Tab S11 Ultra are top-tier devices with best-in-class screens, processors, and connectivity. The Surface Pro 11 is a productivity workhorse. The Xiaomi Pad 7 and Lenovo Idea Tab Pro sit in the mid-range but still blow past the EJ-A4 on any meaningful spec. The EJ-A4's 9th percentile connectivity and 7th percentile feature set put it at the opposite end of the spectrum. The only place it wins is price, and even then, you're comparing a 3,436 JPY accessory pack to devices that cost fifty to a hundred times more. It's not a fair fight, and it's not meant to be.

At 3,436 JPY for five pairs, the per-unit cost is the only thing keeping this product alive. You're paying roughly 687 JPY per earbud, which is cheaper than a convenience store onigiri. For a classroom, a daycare, or a family with kids who destroy everything they touch, that's genuinely hard to argue with. But value isn't just about low price. The productivity score of 11.3 and the overall score of 19.8 suggest you're getting exactly what you pay for, and maybe less. If you need one pair that sounds decent and lasts, this isn't it. If you need five pairs that exist and make sound, the math checks out.

The Inchic EJ-A4 is a 5-pack of wired earbuds aimed at classrooms, kids, and anyone who needs cheap backup audio. The headline number is the price: 3,436 JPY for five pairs, which works out to under 700 JPY per earbud. That's the whole pitch. You're not buying audio quality here, you're buying quantity and convenience.

Our database puts this at 19.8 out of 100 overall, which is about as low as it gets. The best use case is entertainment at 20.2, and even that's nothing to write home about. Reading lands at 18, and productivity bottoms out at 11.3. If you're expecting anything beyond basic sound for online classes and phone calls, you'll be disappointed. But for a classroom set or a family drawer full of spares, the math might work.

Anyone buying for themselves should skip this. The 19.8 overall score and 7th percentile feature ranking mean you're getting the bare minimum. If you care about music, the lack of any audio specs is a red flag. If you need earbuds for work calls or long meetings, the 11.3 productivity score is a dealbreaker. And if you've ever been annoyed by a flimsy cable or a mic that picks up everything except your voice, the 9th percentile connectivity ranking should send you running. Spend a bit more on a single decent pair instead of five mediocre ones.

The Inchic EJ-A4 is a bulk buy for people who need disposable audio. The 19.8 overall score and 7th percentile feature ranking tell the story: this is a no-frills product with zero ambition beyond being cheap and available. For a classroom setting where earbuds get lost, broken, or shared constantly, five pairs for 3,436 JPY is a pragmatic choice. For anyone who cares about sound quality, durability, or even basic comfort over long sessions, look elsewhere. The productivity score of 11.3 is a warning sign for anyone planning to use these for work calls or long online meetings.
