If you want a fun, rechargeable pair of kids' headphones with light-up cat ears and the freedom of wireless listening, choose HOYJACY Cat Ear Kids; if you need to equip a whole classroom, computer lab or office with thirty simple wired pairs at once, choose Konohan 30. These two products barely live in the same category, and that's the whole point of this comparison. One is a single gift-style Bluetooth headset for a child. The other is a bulk box of thirty wired pairs built for shared, repeated use. Let me break down what each one actually is and who it genuinely fits.
• HOYJACY Cat Ear Kids — biggest strength: Bluetooth 5.0 wireless plus a 3.5mm wired fallback, LED cat ears, and a foldable, adjustable over-ear build aimed at kids and teens.
• HOYJACY Cat Ear Kids — biggest trade-off: It's a single pair with no active noise cancellation, so it's a personal gift item, not something you buy to outfit a group.
• Konohan 30 — biggest strength: Thirty wired over-ear headphones in one box, each with a 4.5-foot cable and a standard 3.5mm plug — ready to hand out to a class or a lab.
• Konohan 30 — biggest trade-off: Wired only, no Bluetooth, no lights, no battery — purely functional black plastic built for volume, not for fun.
• Pick HOYJACY Cat Ear Kids if you're buying for one child who wants a cool, colorful, wireless-capable headset.
• Pick Konohan 30 if you're an educator, school, library or office manager who needs many pairs at once and doesn't want to manage charging.
The HOYJACY Cat Ear Kids is, first and foremost, a designed object. The headline feature is the cat-ear shape with flashing LED lights, which turns a pair of headphones into something a child actually wants to wear. In my opinion, that matters more than people admit — kids who like their gear are far more likely to treat it carefully. It's a pink, over-ear, plastic-bodied headset with rounded earcups, and it's clearly positioned as a gift: school, birthdays, holidays.
On the tech side, it runs Bluetooth 5.0 with a wireless range of about 10 meters, so a kid can move around a room without dragging a cable. Crucially, it also includes a 3.5mm audio cable. That wired mode is the safety net: when the battery runs down, the headphones keep working over the cable instead of becoming a paperweight. The audio side is a dynamic driver with a 20Hz–20,000Hz frequency range, which is the standard full-range window — perfectly reasonable for music, videos and classroom audio.
Comfort and portability are the other two pillars here. The headband is adjustable and the ear cushions are described as soft and skin-friendly, which is what you want for longer sessions. And the whole thing folds, so it slips into a backpack or a carry-on without fighting for space. It weighs about 0.32 kg, so it's light enough for a child to wear and carry without complaint.
Who should buy it? A parent, grandparent or friend buying for one girl, child or young teen who'd get a kick out of the light-up ears and the wireless freedom. Who should skip it? Anyone who needs to equip a group, and anyone who wants active noise cancellation — this model has none. This is a personal, fun-first headset, not a fleet purchase.
The Konohan 30 is a completely different animal, and the name tells you why: it's a 30-pack. You don't buy this for one person. You buy it because you have thirty people who all need a working pair of headphones at the same time — a classroom, a school library, a computer lab, an office, or a set of seats on a plane or a shared workstation setup.
Every pair is wired, with a 3.5mm plug that fits the headphone jacks on the vast majority of laptops, desktops, tablets and in-flight entertainment systems. There's no Bluetooth, no battery and no charging — which, for a bulk purchase, is actually the appeal. Nothing to pair, nothing to run flat, nothing to lose track of on a charging cart. Hand them out, collect them, done.
Who should buy it? Schools, teachers, librarians, IT staff and office managers who need to equip a room efficiently. Who should skip it? A single buyer who just wants one pair, a kid who wants wireless, or anyone who wants the light-up, gift-style experience. Buying thirty when you need one is obviously the wrong call.
Side-by-Side: Which Should You Choose?
• Best for a gift or single child → HOYJACY Cat Ear Kids. The LED cat ears and pink over-ear design are built to be enjoyed by one kid.
• Best for a classroom, lab or library → Konohan 30. Thirty wired pairs in one order is the whole reason this product exists.
• Best for wireless freedom → HOYJACY Cat Ear Kids. Bluetooth 5.0 with roughly 10 meters of range means no cable during normal use.
• Best for zero charging hassle → Konohan 30. Wired-only means nothing to charge and nothing to pair.
• Best for a battery backup plan → HOYJACY Cat Ear Kids. The included 3.5mm cable keeps it working when the battery is low.
• Best for portability and storage → HOYJACY Cat Ear Kids. The foldable design and light 0.32 kg build make it easy to pack.
• Best for tidy, low-tangle cable management at scale → Konohan 30. The 4.5-foot cable is meant to be adjusted and kept organized.
• Best for noise isolation → Konohan 30. It lists sound isolation, while the HOYJACY lists no noise control at all.
• Best for outfitting many people on a budget-per-unit basis → Konohan 30. Buying in bulk is the point; you'll want to check the current price on Amazon for both before deciding.
My Verdict
Both. It's primarily a Bluetooth 5.0 wireless headset with about 10 meters of range, but it also ships with a 3.5mm audio cable so you can keep using it wired when the battery is low.
Thirty. It's sold as a bulk pack of 30 wired over-ear headphones, each with a 3.5mm plug and a 4.5-foot cable, intended for schools, libraries, labs and offices.
No. The HOYJACY Cat Ear Kids lists no noise control at all. The Konohan 30 lists sound isolation, which is passive blocking from the over-ear fit rather than active noise cancellation.
The Konohan 30. Wired, no batteries to charge, no pairing, and thirty pairs in one order make it the practical choice for a group. The HOYJACY is a single-pair gift item, not a classroom set.
