How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a big classroom-ready pack of simple wired earbuds in mixed colors, choose Kanayu 100; if you need on-ear student headphones with an adjustable headband and a bulk pack sized for a class set, choose ZXQZYM Kids Headphones Bulk. That is the short version for anyone buying for students — whether that is a school lab, a library checkout desk, or a set you keep for jogging and PE warm-ups.
• Kanayu 100 — biggest strength: a 100-piece bulk pack of multicolor wired earbuds with a 3.5 mm jack, no microphone, and a long PVC cable designed to survive classroom use.
• Kanayu 100 — biggest trade-off: they are in-ear buds with no mic, so there is no voice assistant support and no on-ear cushioning for long listening sessions.
• ZXQZYM Kids Headphones Bulk — biggest strength: a 30-pack of on-ear headphones with an adjustable headband, soft ear cushions, and a single shared cord that keeps tangles down.
• ZXQZYM Kids Headphones Bulk — biggest trade-off: fewer units per pack, and the on-ear fit is bulkier to store than a small bag of earbuds.
• Who each pick is for: Kanayu 100 suits schools, libraries, gyms and event giveaways that need a large quantity of lightweight buds; ZXQZYM Kids Headphones Bulk suits classrooms, testing rooms and computer labs that want a comfortable on-ear set sized per class.
Kanayu 100 is a 100-count bulk pack of wired in-ear earbuds. Each pair uses rounded silicone tips and a 3.5 mm jack, and there is no built-in microphone, so the design is purely about listening — no call handling, no voice pickup. The cable is PVC and measures 35.43 inches (90 cm), which is a sensible length for sitting at a desk or laptop without a lot of slack tangling up. The drivers are dynamic with a 20 Hz – 20,000 Hz frequency range, and the noise control is passive, meaning the silicone tips simply block some outside sound by sealing the ear.
Comfort is the selling point here. Soft silicone tips that rest in the ear rather than clamp around it stay tolerable for long stretches, which matters when a student is working through a lesson or a training video. The multicolor approach is a quiet logistical win too — in a room full of identical hardware, color makes it easy to hand out, collect and sort. The pack is aimed at kids, teens and adults, and the manufacturer lists schools, libraries, hotels, museums, gyms, birthday parties and reward gifts as intended uses.
Who should buy it: anyone who needs a large quantity of simple, jack-only earbuds for group learning, training sessions, computer stations or event giveaways. Who should skip it: anyone who needs a microphone for online classes, voice assistant use, or anything involving two-way audio — there is none here. Also skip it if you want on-ear cushioning; these are in-ear by design.
ZXQZYM Kids Headphones Bulk is a 30-pack of wired on-ear headphones in mixed colors, individually sealed for storage and distribution. The headband adjusts, so the same set can fit younger kids, teens and adults without swapping hardware between age groups. The earpieces are on-ear with soft cushions, and the drivers are dynamic with 32 ohm impedance — an easy load for a laptop, Chromebook or tablet headphone jack.
Two details stand out for classroom reality. First, the single shared cord: instead of two cables running to each ear, there is one, which cuts down on the tangle that eats up time during hand-out and clean-up. Second, the on-ear cushions support extended listening better than bare buds for many students, which matters in language labs, testing sessions and long video lessons. ZXQZYM also states a one-year warranty and describes a customer support channel for keeping learning uninterrupted.
Who should buy it: schools, libraries, learning centers and testing rooms that want a class set of comfortable on-ear headphones with a fit that adapts across ages. Who should skip it: buyers who need a very large quantity for a giveaway or event, since this pack is sized for a class rather than a crowd. Also skip it if you specifically want an in-ear fit or a sealed silicone tip — this is an on-ear design with no noise control listed.
• Best for pack size → Kanayu 100. 100 units versus 30, which is a big difference if you are stocking a whole school, a gym or an event.
• Best for on-ear comfort during long sessions → ZXQZYM Kids Headphones Bulk. Soft ear cushions and an adjustable headband are built for extended listening.
• Best for a mixed-age class set → ZXQZYM Kids Headphones Bulk. The adjustable headband is explicitly designed to fit kids, teens and adults.
• Best for the smallest, lightest option to store → Kanayu 100. In-ear buds take up far less space than on-ear headphones when boxed up.
• Best for tangle-free distribution → ZXQZYM Kids Headphones Bulk. The single shared cord is a deliberate anti-tangle choice.
• Best for microphone-dependent tasks → neither. Kanayu 100 has no mic, and ZXQZYM lists no microphone either. If two-way audio matters, look elsewhere.
• Best for jogging and PE warm-ups → Kanayu 100. A light in-ear bud with passive noise blocking is easier to keep in place while moving than a padded on-ear headband.
• Best for a smaller, more comfortable per-student upgrade → ZXQZYM Kids Headphones Bulk. Fewer units, but each one is a more substantial piece of hardware.
In my opinion, if you are outfitting a single classroom, testing room or computer lab where students sit and listen for long stretches, I would buy ZXQZYM Kids Headphones Bulk. The adjustable headband, soft on-ear cushions and single cord are the details that actually reduce friction during a school day, and the 30-pack maps neatly onto a class. If your priority is sheer quantity — a whole school, a library desk, a gym, or giveaway sets for events and jogging sessions — I would buy Kanayu 100 instead, because 100 lightweight multicolor buds with a sturdy 90 cm cable cover far more people for the same kind of job.
No. Kanayu 100 explicitly lists no built-in microphone. ZXQZYM Kids Headphones Bulk lists no microphone either, and no voice assistant or inline control. Both are listen-only, which is fine for lessons and videos but not for online calls.
Kanayu 100 uses in-ear silicone tips that seal the ear and provide passive noise cancellation. ZXQZYM uses on-ear cushions that rest against the ear with an adjustable headband. In-ear is smaller and lighter; on-ear is generally more comfortable for long sessions.
Both use a standard 3.5 mm jack and wired connectivity, so they work with any device that has a headphone port. ZXQZYM names Chromebook, laptop and tablet support directly. If your device has no headphone jack, you would need an adapter.
