If you want thirty ready-to-hand-out wired classroom headphones in one box, choose Konohan 30; if you need a single protective storage case for a pair of wireless on-ear headphones you already own, choose Boobowl Headphone Case Compatible.
• Konohan 30 — biggest strength: one purchase covers 30 students, each pair individually sealed in its own bag, with adjustable on-ear cups and a 3.5 mm wired jack that works with almost any school device.
• Konohan 30 — biggest trade-off: it's wired and purely functional — a 4 ft cable, no wireless, no carrying case, and nothing premium about the design.
• Boobowl Headphone Case Compatible — biggest strength: a hard-shell PU case with a soft velvet lining, a waterproof outer, a mesh pocket for a charging cable, and a hand strap sized to fit specific JBL and Sony on-ear models.
• Boobowl Headphone Case Compatible — biggest trade-off: it holds zero headphones — it's the case only, fits a limited list of models, and is useless if your headphones fall outside that list.
• Who Konohan 30 is for: schools, libraries, testing centers, hotels, and anyone buying durable headphones in bulk.
• Who Boobowl Headphone Case Compatible is for: one person protecting one pair of JBL Tune/Live or Sony WH-CH on-ear headphones at home or in a bag.
Konohan 30 is a bulk classroom kit, and it's designed around that single job. You get 30 white wired headphones, each one wrapped and sealed individually in its own OPP bag. That detail matters more than it sounds. In a school setting, individual wrapping means you can hand a pair to a student without the "who used this last" problem, and it keeps the cups from getting scuffed while they're stored between sessions. It's a small design choice that tells you who this product was built for.
The hardware itself is deliberately plain and tough. The shell is ABS with soft rubber ear pads, on-ear cups that rotate, and an adjustable headband that's meant to sit securely without sliding off during a lesson. The pads are described as durable and elastic, comfortable enough for longer wear, and they block outside noise to some extent through sound isolation — enough to help a student focus in a noisy room, not enough to pretend it's active noise cancellation. The cable runs about 4 ft / 120 cm and ends in a 3.5 mm jack with high-fidelity stereo sound, so it plugs into laptops, tablets, desktops, media players, and listening consoles without any pairing or charging step. There's also a remote with volume control on the cable.
Who should buy it: anyone outfitting a room. Teachers, testing coordinators, librarians, hotel managers, training departments. Thirty pairs in one order, no batteries to manage, no pairing, no charging cart. Who should skip it: a single person who wants one nice pair of headphones for themselves, or anyone who wants wireless. Wired is the whole point here, and if you don't need 30, you're paying for volume you won't use.
Boobowl Headphone Case Compatible: Who It's For
Boobowl Headphone Case Compatible is a completely different kind of product — it doesn't play audio at all. It's a storage case for wireless on-ear headphones, and its compatibility list is specific: JBL Tune 510BT, 520BT, 500, 660, JBL Live 460NC and 670NC, and Sony WH-CH520 and WH-CH510. If your headphones are on that list, the fit is the reason to buy it. If they aren't, nothing else about the case will save it.
The build is where the value sits. The outside is PU material with a waterproof finish, so a damp commute or a rainy walk to the car won't soak through. The lining is soft velvet, which is the part that actually protects your headphones — it wraps the cups and keeps the plastic and hinges from scuffing against each other in a bag. Durable, scratch-resistant materials resist everyday wear, and the hard shell type means it holds its shape instead of collapsing onto the earcups. The listed internal size is 7.48 inches with a max compatible device size of 7.48 inches, so it's cut close to the headphones it names.
Then there's the organization angle. A dedicated mesh pocket holds a charging cable so it doesn't tangle with the headphones or get lost at the bottom of a backpack. A 360-degree zipper with a spacious opening makes the case easy to load and unload, and the hand strap means you can carry it on its own or drop it into a larger bag. It's ultra-thin and lightweight at 0.16 kg, so it doesn't add bulk to a trip.
Who should buy it: one person with one of the listed JBL or Sony on-ear models who wants that pair protected at home, in an office, or in a suitcase. It's also a sensible gift for someone who owns those headphones — the case itself is pink, and the listing frames it as a holiday, birthday, or business gift. Who should skip it: anyone with a different headphone model, anyone who wants over-ear full-size protection (the internal size is the limit), and anyone expecting headphones in the box. The listing is explicit that only the case is for sale.
• Buying for a class, lab, library, or testing room → Konohan 30. Thirty sealed pairs, wired, no charging, no pairing, ready to distribute.
• Buying for yourself or a gift, one pair → Boobowl Headphone Case Compatible. It's a single case for a single set of headphones.
• You need headphones that actually produce sound → Konohan 30. The Boobowl case contains no electronics and no drivers.
• You own JBL Tune 510BT/520BT/500/660, JBL Live 460NC/670NC, or Sony WH-CH520/510 → Boobowl Headphone Case Compatible. That's the exact compatibility list; outside it, look elsewhere.
• You want protection from water, scratches, and knocks → Boobowl Headphone Case Compatible. Waterproof PU shell, velvet lining, hard shell type.
• You want cable management built in → Boobowl Headphone Case Compatible. The mesh pocket is made for a charging cable.
• You want a cable long enough to move at a desk → Konohan 30. Roughly 4 ft / 120 cm of wire with a 3.5 mm plug and inline volume control.
• You want the option to use it in multiple rooms without recharging → Konohan 30. Wired means no battery to top up between lessons.
• You need both jobs done → buy both, but for different reasons. One outfits a room; the other protects one pair you already own.
In my opinion, the answer here is almost entirely about which problem you have, and the products barely overlap. If I were equipping a classroom, library, or testing center, I'd buy Konohan 30 without hesitation: 30 individually sealed wired pairs, adjustable on-ear fit, rotating cups, and a 3.5 mm jack that works with the devices schools actually use. The trade-off is that it's basic and wired, and that's fine for the job. If I already owned a JBL Tune 510BT or Sony WH-CH520 and wanted to stop throwing it loose into a backpack, I'd buy Boobowl Headphone Case Compatible — the waterproof PU shell, velvet lining, hard shell, and mesh cable pocket are exactly what a commute bag needs. Just confirm your model is on the compatibility list first, because that's the whole product. If you truly can't decide, ask yourself whether you need sound or storage. That one question settles it.
FAQ
Only if they're on the compatibility list: JBL Tune 510BT, 520BT, 500, 660, JBL Live 460NC, 670NC, and Sony WH-CH520 or WH-CH510. The internal size is 7.48 inches, which matches the max compatible device size, so it's cut for those models rather than oversized.
Thirty pairs, in white, each wrapped and sealed individually in its own OPP bag. That's the number of items listed, and it's the core of what you're buying — enough for a full class or a shared lending shelf.
No. The data lists a wired 3.5 mm jack, a dynamic driver, sound isolation for blocking outside noise to some extent, and an inline remote with volume control. There's no Bluetooth and no microphone listed, so treat it as a wired listening headphone for lessons, libraries, and testing.
