How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a bigger classroom-ready bundle with padded on-ear comfort and a rotatable-cup design, choose Konohan 30; if you need a smaller, multi-color bulk set for younger kids where color variety and mix-and-match matter more than padding, choose ZXQZYM Bulk Headphones 20.
• Konohan 30 — biggest strength: 30 individually wrapped headphones in one order, on-ear cups with soft rubber/foam padding, a rotatable cup design, and an adjustable headband built for long study sessions.
• Konohan 30 — biggest trade-off: Bulkier packaging and a single black colorway, so you lose the visual variety younger kids often like.
• ZXQZYM Bulk Headphones 20 — biggest strength: A 20-pack in multi-color with fabric-and-silicone ear cushions, sealed individually inside a carton box, and a stated 1-year warranty.
• ZXQZYM Bulk Headphones 20 — biggest trade-off: Fewer units per order, no passive noise cancellation, and a plainer functional styling than the Konohan set.
• Who Konohan 30 is for: Teachers, labs, libraries and testing rooms that need a large, uniform, comfort-focused fleet.
• Who ZXQZYM Bulk Headphones 20 is for: Elementary and middle-school classrooms that want color-coded sets and a slightly smaller, easier-to-manage count.
The Konohan 30 is built around one idea: getting a lot of usable headphones into a room without anyone fighting over who gets which pair. You get 30 units, each sealed in its own OPP bag, which matters more than it sounds — individually wrapped sets are easier to hand out, easier to store, and easier to keep hygienic between class periods or testing sessions. That single detail tells you this set was designed for shared, rotating use rather than one kid's backpack.
On the comfort side, the sheet is specific: ABS shell, soft rubber ear pads, an adjustable headband, and cups that rotate. The rotating cups are the detail I'd underline for anyone buying for a computer lab. When 25 students are pulling headphones on and off between tasks, a cup that pivots to the ear instead of forcing the ear to the cup is the difference between a headphone that survives the semester and one that gets yanked apart. The adjustable band is aimed at mixed-age rooms — kids, teens and adults sharing the same hardware. The 4 ft / 120 cm cable is a practical length for a laptop or desktop at arm's length, and the 3.5 mm jack covers the usual mix of phones, tablets, laptops and listening consoles.
Buy it if you're outfitting a classroom, library, lab or testing room and want a large, uniform, comfort-first set with individually sealed units. Skip it if you specifically want multiple colors for young kids, or you only need a small number of pairs — 30 is a lot of hardware to store.
ZXQZYM Bulk Headphones 20: Who It's For
The ZXQZYM set takes a different angle: 20 units, multi-color, aimed squarely at kids, teens and adults in school settings. The color mix is the headline. Anyone who has run a primary classroom knows that color-coded headphones end arguments — "you're the blue pair" is a faster and calmer system than numbered bins. If that matters to you, this pack solves a problem the Konohan set doesn't even try to solve.
Comfort is handled with soft ear cushions and an on-ear, rounded shape, and the enclosure uses fabric and silicone rather than the hard-shell ABS of the other set. That combination tends to feel a little softer against the head, which suits younger wearers who are fussier about pressure. The 4 ft cable and 3.5 mm jack line up with the same everyday hardware: tablets, PCs, desktops, laptops, Chromebooks and fitness equipment. The 32 ohm impedance and 20 Hz–20,000 Hz range are effectively identical to the Konohan's, so on paper neither set has an audio advantage — both are standard, easy-to-drive classroom headphones.
Packaging is worth noting: the whole order arrives in a carton box with each headphone sealed in its own bag. That's a tidy storage story, and the listed 1-year warranty is a real reassurance for a school that has to justify the purchase.
The trade-offs are real, though. There's no noise control at all here — no passive cancellation, nothing — so if you're buying partly to blunt background noise on a plane, a bus or a loud cafeteria, this isn't that product. The count is also 20, not 30, so it fits a smaller room or a single class rather than a whole department.
Buy it if you want multi-color headphones for younger students and a manageable 20-unit count with a stated warranty. Skip it if you need a larger fleet, noise-dampening padding, or a single consistent color for a testing environment.
• Best for larger classrooms and labs → Konohan 30. 30 units versus 20 means fewer re-orders and enough spares for a full room.
• Best for color-coded younger kids → ZXQZYM Bulk Headphones 20. The multi-color set is the clear pick when assigning colors matters.
• Best for noise reduction → Konohan 30. It has passive noise cancellation and soft padded cups; the ZXQZYM has no noise control feature at all.
• Best for a smaller budget footprint on storage → ZXQZYM Bulk Headphones 20. Fewer units means less shelf space and less hardware to track.
• Best for mixed-age rooms → Konohan 30. The adjustable headband and rotating cups are explicitly built to fit kids, teens and adults.
• Best for a stated warranty → ZXQZYM Bulk Headphones 20. A 1-year warranty is listed; the Konohan sheet doesn't state one.
• Best for uniform testing environments → Konohan 30. One color, one spec, no "I got the wrong pair" disputes.
• Best for softer head-feel on kids → ZXQZYM Bulk Headphones 20. Fabric and silicone construction with soft cushions is the gentler build on paper.
If I were outfitting a school or lab and had to pick one, I'd buy the Konohan 30. In my opinion it wins on the things that actually break headphones in shared use: padded on-ear cups, a rotating cup design, an adjustable band for mixed ages, and passive noise cancellation — plus 30 individually sealed units so a full class is covered in one order. The ZXQZYM Bulk Headphones 20 is the better call only if multi-color sets and a smaller count genuinely fit how you run your room. Check the current price on Amazon for both before deciding, since that's the one variable that can flip the math.
