• Kanayu 100 — biggest strength: It is a 100-piece bulk pack of individually bagged white wired earbuds with a 3.5 mm jack, no microphone and a 90 cm PVC cable, built for classrooms, libraries and giveaway events.
• Kanayu 100 — biggest trade-off: There is no microphone, no in-line control and no carry case, so it is not the pair you reach for when you need to take calls.
• ASKUBSKU School Earbuds — biggest strength: A single pair with a built-in microphone, button volume control, semi in-ear angled fit and a storage case, aimed at one person using a phone, tablet or laptop.
• ASKUBSKU School Earbuds — biggest trade-off: It is one pair, not a set, and the in-line volume control is not available on iOS devices, so iPhone users lose one of its main features.
• Who each pick is for: Kanayu 100 for teachers, schools, museums, gyms and event organisers equipping many people; ASKUBSKU School Earbuds for one student or commuter who wants calls, music and a case.
The Kanayu 100 is not really a "pick one pair" product. It is a supply decision. You get 100 white wired in ear earbuds, each one individually bagged, with a 3.5 mm jack and a 90 cm PVC cable. The silicone tips are soft, the enclosure is PVC and silicone, and the earpieces sit in the ear rather than pressing on it. The dynamic driver covers a 20 Hz to 20,000 Hz range, which is the standard full-range spread — enough for spoken word, video audio and everyday listening.
The detail that matters most here is what is missing: there is no built-in microphone. For a classroom that is often a feature, not a flaw. A mic-free earbud is simpler, has fewer parts to fail, and is exactly what you want when 30 students are listening to a lesson rather than talking into a headset. The 90 cm cable is a sensible length for a desk, a laptop or a library station — long enough to move your head, short enough not to tangle into a mess.
Who should skip it? Anyone buying for themselves. If you want one pair for your commute, take calls, or adjust volume without touching your phone, this pack is the wrong shape of product — you would be paying for 99 pairs you do not need, and you would still be missing a microphone and controls. Skip it too if you need a carry case or a hard-wearing metal housing.
ASKUBSKU School Earbuds: Who It's For
The ASKUBSKU School Earbuds are built around one person's daily use. You get a single pair of black wired in ear earbuds with a 3.5 mm jack, a metal enclosure, a dynamic driver and the same 20 Hz to 20,000 Hz frequency range as the Kanayu set. The sound design is described as a high-amplitude, low-distortion driver tuned for bass detail and clear mid and high pitch — in plain terms, a pair meant to make music and dialogue sound lively rather than flat.
The ergonomics are the interesting part. This is a 45-degree semi in-ear design, angled to sit into the ear canal without the pressure of a fully sealed tip. That is a real difference for long sessions: less of that plugged, sore feeling after an hour of lectures, flights or gaming. The listing also flags that the angle matters when you put them in — you seat them at 45 degrees rather than jamming them straight in.
Then there is the feature set you would actually miss on a basic pair: a built-in microphone for calls, in-line button volume control, and a storage case included. The mic is described as tuned to lift voice clarity, which is the practical difference between "listening earbuds" and "meeting earbuds". The case matters more than people expect — it is what stops a loose pair from becoming a tangled, pocket-lint-covered mess.
Who should buy it? A student or commuter who wants one reliable pair for a laptop, PC, tablet or Android phone — the listing names a long list of Samsung Galaxy, Pixel, Motorola, OnePlus, Redmi and POCO models, so Android owners are clearly the target. Also anyone who takes calls, watches films on a flight, or wants volume control at their fingertips.
Side-by-Side: Which Should You Choose?
• Best for equipping a whole class → Kanayu 100. 100 individually bagged pairs, no microphone, no controls to break.
• Best for one person's everyday use → ASKUBSKU School Earbuds. A single pair with mic, volume control and a case.
• Best for calls and online meetings → ASKUBSKU School Earbuds. The Kanayu 100 has no microphone at all.
• Best for handing out at events or as rewards → Kanayu 100. The bulk format and white colour suit giveaways and counting stock back in.
• Best for long, comfortable wear → ASKUBSKU School Earbuds. The 45-degree semi in-ear angle is designed to avoid earpress over long sessions; the Kanayu relies on soft silicone tips instead.
• Best for a tidy bag or pocket → ASKUBSKU School Earbuds. It ships with a storage case; the Kanayu pairs come in individual bags with no case.
• Best for Android phones → ASKUBSKU School Earbuds. In-line volume control works there, but not with iOS devices.
• Best for a shared desk, library or gym station → Kanayu 100. Simple, mic-free, PVC-cabled pairs you can replace without thinking.
For my own bag, I would buy the ASKUBSKU School Earbuds. In my opinion, the microphone, the in-line volume control, the 45-degree semi in-ear fit and the included case make it the more useful pair for one person, and the metal housing suggests it will hold up to daily pocket life. I would only pick the Kanayu 100 if my goal were bulk supply — a classroom, a library, a gym or an event where 100 mic-free pairs with 90 cm cables solve a real logistical problem. Two different jobs, two different answers. Check the current price on Amazon for whichever one matches yours.
FAQ
how to make wired earbuds stay in ear
how to put earbuds in your ear
Gently pull the top of your ear up and back to open the canal, then insert the earbud and let it settle. With the ASKUBSKU earbuds, follow the 45-degree semi in-ear angle the manufacturer describes instead of forcing them deeper. With either pair, a light seal beats a hard push — pressing too hard is what causes soreness, not the earbud itself.
how to keep earbuds in ears
Keep the cable from tugging. A 90 cm cable like the Kanayu 100's is short enough to stay on a desk, but if it snags on a chair or bag it will pull the earbud out. Route the cable over your ear or under your shirt, and avoid yanking the plug out by the wire — that is also the fastest way to damage a PVC cable.
how to make apple wired earbuds stay in ear
Worth knowing before you buy: the ASKUBSKU in-line volume control does not work with iOS devices, so on an iPhone or iPad you would get audio and the microphone but no button volume. If you are buying for Apple hardware, plan to adjust volume on the device itself, and focus on getting the 45-degree angle right for a stable fit.
