We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a bulk classroom set of wired in-ear earbuds with a 3.5mm jack, choose Konohan 100; if you need a smaller pack of on-ear USB-C headphones students can share by color, choose OYSLKJ 5. Both are wired, both skip the microphone, and both are aimed squarely at schools. The difference is the connector, the fit, and the size of the pack — and that's what decides it.
• Konohan 100, biggest strength: 100 individually wrapped in-ear earbuds in one bulk lot, so a whole classroom, testing lab or library counter can be stocked in a single order.
• Konohan 100, biggest trade-off: 3.5mm wired earbuds with no microphone and no noise control — fine for testing, useless for anything that needs a mic.
• OYSLKJ 5, biggest strength: on-ear headphones with an adjustable headband and soft cushions, in five distinct colors (black, dark blue, pink, purple, teal) so students can tell their pair apart instantly.
• OYSLKJ 5, biggest trade-off: only 5 pairs per pack, and they're USB-C only — they won't fit older 3.5mm jacks.
• Pick Konohan 100 if you're equipping a room full of 3.5mm devices and need volume.
• Pick OYSLKJ 5 if you're outfitting a handful of students on USB-C Chromebooks, tablets or phones and want on-ear comfort plus color coding.
This is a quantity play, and it's honest about it. You get 100 in-ear earbuds, each one wrapped individually in a bag. That single detail tells you the intent: this is a set meant to be handed out, collected, stored and handed out again. Testing centers, libraries, museums, hotels and gyms are the listed use cases, and they all share the same problem — lots of people, lots of devices, and a need for something cheap enough to lose and simple enough to hand over without instructions.
The build is soft silicone with rounded tips, in white, on a 90 cm PVC cable. The silicone is what makes the fit work for long stretches; the product notes describe it as comfortable without pressure and not prone to falling out. The drivers are dynamic with a 20 Hz – 20,000 Hz range, and the sound is described as clear rather than punchy — which is exactly what you want for spoken-word testing, audiobooks and lecture audio. There is no microphone and no noise control, and the control method listed is touch. Compatibility is plain 3.5mm, so phones, laptops, desktops, MP3 players, iPads, iPods and fitness equipment all work.
OYSLKJ 5: Who It's For
The OYSLKJ 5 goes the other direction: fewer units, but a more substantial object. These are on-ear headphones, not earbuds, which means an adjustable headband and soft ear cushions that sit against the ear rather than inside it. For kids and teens who find in-ear tips uncomfortable, or who fidget with them, that's a real difference in how long they'll actually keep the things on during a lesson.
The headline feature is the five colors — black, dark blue, pink, purple and teal. In a classroom, that's not decoration, it's logistics. Each student grabs their color, knows which pair is theirs, and you stop losing track of whose headphones are whose. The connection is USB-C, which lines up with the Chromebooks, tablets, phones and laptops that have dropped the old headphone jack. Impedance is 32 ohm, a standard, easy-to-drive figure, so you don't need anything special to power them.
Like the Konohan set, there's no microphone — the product positions this as a focus feature, keeping students on online lessons, audiobooks, reading apps and educational video rather than chatting. The age range covers kids, teens and adults, and there's a 1-year warranty listed, which is worth noting for a school purchase. The trade-off is the connector: USB-C only, so anything with a 3.5mm socket is out unless you add an adapter, and five pairs won't cover a large room.
Buy it if you're equipping a small group on USB-C devices and want on-ear comfort with color-coded ownership. Skip it if you need 3.5mm compatibility or you're buying for a whole grade.
• Best for stocking a whole classroom → Konohan 100. 100 pairs versus 5 is not a close call if volume is the requirement.
• Best for USB-C devices → OYSLKJ 5. Chromebooks, USB-C tablets and newer phones plug straight in with no adapter.
• Best for older 3.5mm gear → Konohan 100. Laptops, desktops, MP3 players and fitness equipment with a standard jack all work out of the bag.
• Best for comfort over long sessions → OYSLKJ 5. An adjustable headband and soft cushions beat in-ear tips for students who dislike things in their ears.
• Best for shared-use hygiene and storage → Konohan 100. Each pair arrives individually wrapped, which suits hand-out-and-collect routines.
• Best for classroom organization → OYSLKJ 5. Five named colors make it obvious who owns which pair.
• Best for testing and quiet focused listening → either, with a caveat. Both are mic-free, so neither is right for calls, but both suit test audio and study material.
• Best for a single student or a small family → OYSLKJ 5. A 100-pack makes no sense for one learner.
In my opinion, the right pick comes down to one question: how many students, and what port? If you're running a testing room, library or lab full of 3.5mm devices and you need to hand out dozens of pairs, I'd buy the Konohan 100 — the individually wrapped bulk format is built for exactly that job, and the silicone in-ear fit and 20 Hz–20,000 Hz dynamic drivers cover everyday listening and test audio without fuss. If instead you're equipping a small group of kids on USB-C Chromebooks, I'd buy the OYSLKJ 5: the on-ear cushions, adjustable headband and five distinct colors solve the two problems that actually slow a classroom down — comfort and "whose is this?" Check the current price on Amazon before you commit, since pack size is doing most of the work in this comparison.
FAQ
No. Both the Konohan 100 and the OYSLKJ 5 are explicitly mic-free, so neither is suited to calls or anything needing voice input — they're for listening only.
Not directly. The OYSLKJ 5 uses a USB-C connector, so a 3.5mm-only laptop would need an adapter. The Konohan 100 uses a standard 3.5mm jack and plugs into those devices directly.
The OYSLKJ 5 is on-ear with an adjustable headband and soft cushions, which tends to suit kids who dislike in-ear tips. The Konohan 100 is in-ear silicone, described as comfortable and secure but still an in-ear fit.
I don't quote prices here — check the current price on Amazon, since pack size (100 pairs versus 5) is the main thing that separates these two.
