How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single pair of wired headphones built for one student's daily school-and-travel routine, choose AILIHEN C8; if you need a whole classroom or testing lab supplied at once with adjustable, shareable headphones, choose Konohan 30.
• AILIHEN C8 biggest strength: A single, comfortable on-ear headset with an inline volume and call-control remote on a 3.5 mm cord — one kid, one pair, ready for class or homework.
• AILIHEN C8 biggest trade-off: It's a single unit with a fixed 3.5 mm wired connection, so there's no headband adjustability called out in the specs and no sharing across a room.
• Konohan 30 biggest strength: An explicitly adjustable on-ear headband plus rotating cups and a 30-pack count — built for classrooms, libraries and testing centers.
• Konohan 30 biggest trade-off: It comes as a bulk 30-pack, which is overkill (and wasteful) for a single student or a single desk.
• Who AILIHEN C8 is for: One student, teen or adult who wants their own comfortable wired headphones with volume control.
• Who Konohan 30 is for: Teachers, schools, libraries and test administrators who need many adjustable pairs at once.
The AILIHEN C8 is a single pair of wired on-ear headphones aimed at one person. The 3.5 mm jack plugs into a Chromebook, computer, tablet or phone, and the cord carries an inline remote for volume and call control. That remote is the detail that matters most day to day: your kid can nudge the volume down mid-lesson without reaching for the laptop, and answer a call without unplugging.
Comfort is where the C8 leans hard. The earcups are rounded on-ear pads in faux leather, designed to sit against the ear rather than around it, and the whole thing weighs 180 g. The circular cups fold up into roughly the palm of your hand, which is the difference between headphones that live in a backpack and headphones that get left on a desk. A nylon carrying case is included, so the folding actually has somewhere to go.
On audio, the spec sheet lists 32 ohm impedance, a dynamic driver and a 20 Hz frequency response. That's a low-impedance, easy-to-drive design — the kind of load a phone or a school laptop handles without a separate amp. Noise control is listed as sound isolation, meaning the padded cups physically block some surrounding noise rather than cancelling it electronically. Expect it to take the edge off a noisy room, not silence a bus.
Buy it if you're equipping one student (or one adult) who wants a comfortable, foldable, volume-controllable headset for class, online learning, homework or travel. Skip it if you're outfitting a whole classroom — one pair can't cover a room, and there's no stated headband adjustment for growing kids to fine-tune the fit.
The Konohan 30 is a different animal entirely: a 30-pack of wired on-ear headphones, each individually wrapped and sealed in its own bag. That packaging detail is the whole point for institutional buyers. Individually sealed pairs are hygienic to hand out, easy to store, and protected against the bumps and scrapes that kill shared classroom gear.
The headline feature for this comparison is right in the name of the category: an adjustable headband. Konohan states the headband adjusts to fit different head shapes, so it stays put instead of sliding off, and the cups rotate for a better fit. That adjustability is what lets one product serve a room full of different-sized kids, teenagers and adults. The ear pads are soft rubber over an ABS shell — a lightweight, hard-wearing combination chosen for daily student abuse rather than audiophile listening.
Each pair has a 3.5 mm plug on a roughly 4 ft (120 cm) cord, which is enough slack to reach a laptop on a desk or a tablet on a lap. The listed impedance is 32 ohm with a dynamic driver and a 20–20,000 Hz range — the standard full-range spec for easy-to-drive consumer headphones, so phones, laptops, tablets, media players and listening consoles will all drive them fine. Noise control is passive, so the padded cups block some outside sound and take the fatigue edge off planes and trains; they don't actively cancel noise. Controls are listed as media control via a remote.
Buy it if you're a teacher, librarian, school or test administrator who needs a stack of adjustable, individually wrapped, budget-friendly headphones that fit a range of head sizes. Skip it if you only need one or two pairs — you'd be paying for 30, and the single-user convenience features (like a dedicated volume-and-call remote) aren't the focus here.
• Best for one student or one desk → AILIHEN C8. One pair, one owner, no leftover stock.
• Best for a classroom, library or testing center → Konohan 30. The 30-pack is the entire reason it exists.
• Best for fit across many head sizes → Konohan 30. It's the one with the stated adjustable headband and rotating cups.
• Best for on-the-fly volume and call control → AILIHEN C8. Its inline remote is listed for volume and call control.
• Best for portability and storage → AILIHEN C8. It folds into the palm of your hand and ships with a nylon case.
• Best for handing out hygienically → Konohan 30. Every pair is individually wrapped and sealed.
• Best for long-session wear comfort → AILIHEN C8 for one user (faux-leather padded cups, 180 g); Konohan 30 for a shared pool (soft rubber pads, ABS shell).
• Best for plug-and-play across devices → a tie. Both are wired 3.5 mm, both are 32 ohm, both use a dynamic driver.
If I were buying for my own kid, I'd get the AILIHEN C8. It's the better single-user product: foldable, light, comfortable, with volume and call controls on the cord, and a case so it survives a backpack. If I were the one running the classroom, I'd buy the Konohan 30 without hesitation — the adjustable headband, the 30 individually wrapped pairs and the ABS-and-rubber build are exactly what a room full of students demands. In my opinion, the right answer here isn't one headphone beating the other; it's matching the product to how many people need to wear it.
FAQ
how to adjust headphones
how to adjust headphones volume
On the AILIHEN C8, use the inline remote on the cord — it's listed for volume and call control, so you don't have to touch your laptop. On the Konohan 30, volume is handled at the source device (phone, laptop or tablet), since its remote is listed as media control.
how to adjust headphones sound
Both pairs are wired 3.5 mm with 32 ohm impedance and a dynamic driver, so the fastest sound adjustment is your device's equalizer. Fit matters too: a snug on-ear seal improves bass, which is another reason the Konohan 30's adjustable headband helps.
The Konohan 30 is the one with a stated adjustable headband and rotating cups, sized for kids, teens and adults. The AILIHEN C8 is a fixed on-ear design with padded cups, so it fits by resting on the ear rather than by sliding a headband. If adjustable fit across many people is your priority, that points to the Konohan 30.
