How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a large, uniform classroom set built for older students and shared labs, choose Yunsailing 30; if you need a smaller, colorful bundle aimed at younger kids with a wider age range, choose OSSZIT Kids Headphones Bulk. Both keep things simple: on-ear cups, wired 3.5 mm plugs, and volume controls. The real difference is scale, audience, and how each set is meant to be handed out and managed.
• Yunsailing 30 biggest strength: a 30-piece set with each headset individually sealed in its own OPP bag, so distribution and storage in a busy room stay organized.
• Yunsailing 30 biggest trade-off: it is a big, single-purpose bulk buy in one color, and it is positioned for users aged 14 and above rather than young children.
• OSSZIT Kids Headphones Bulk biggest strength: a 10-pack in 10 colors, aimed at kids, teens and adults, with a stated 1-year warranty and 32 ohm impedance.
• OSSZIT Kids Headphones Bulk biggest trade-off: fewer units per set, so it fits a small group or single classroom better than a whole department.
• Who each is for: Yunsailing 30 is for libraries, computer labs and training spaces that need many identical headsets at once; OSSZIT Kids Headphones Bulk is for a teacher or parent equipping a smaller group of younger students who like having their own color.
The Yunsailing 30 is a bulk set of 30 white on-ear headphones, and the packaging is the headline feature. Each headset comes individually sealed in an OPP bag. If you have ever tried to hand out a tangled pile of shared headphones at the start of a lesson, you already understand why that matters. You can pass them out, collect them, and store them without everything turning into a knot. For rotating users and shared learning environments, that single design choice does more work than any spec on the page.
The build is aimed at frequent handling. The shell is ABS, the cable is PVC and about 1.2 meters (3.94 ft) long, and the whole thing is described as tangle-resistant durability for high-traffic environments. The headband adjusts and the ear cushions are soft, which matters for long sessions of computer work, online learning, assessments and focused listening. A standard 3.5 mm jack plugs into laptops, desktops, tablets and other audio devices, so you are not hunting for adapters. There is also a volume control, which is handy when students are working at different stations.
Who should buy it: anyone running a computer lab, library, training room or group-testing setup who needs a lot of identical headsets and a clean way to distribute them. The stated age range is 14 and above, so this is a set for older students and adult learners, not early elementary kids.
OSSZIT Kids Headphones Bulk: Who It's For
The OSSZIT Kids Headphones Bulk is a 10-pack of on-ear wired headphones in 10 colors. The color variety is the point. When each student has a recognizable pair, you spend less time sorting out whose is whose and more time teaching. The stated age range covers kid, teen and adult, so it stretches across grade levels in a way a strictly older-audience set does not.
On specs, the impedance is listed at 32 ohm, the enclosure is plastic, and the connection is a standard 3.5 mm jack that works with classroom desktops, laptops, Chromebooks, tablets, smartphones and other audio devices. There is a volume control on a remote, and noise control is listed as none, which tells you these are straightforward listening headphones rather than noise-cancelling ones. The listed warranty is 1 year, and the brand states that support questions get a reply within 12 hours. That kind of stated support matters in a school setting, where one broken unit out of ten is annoying and a slow replacement process is worse.
The design language is durability with cost in mind: stronger wires, plastics and 3.5 mm connectors, described as durable and easy to carry. Note the item weight is listed as 0.7 kg, and the number of items field reads 1, which is a packaging/detail quirk rather than a claim about how many headphones you get — the product is described as a 10-pack.
Who should buy it: a teacher, tutor or parent equipping a small class, a reading group or a set of siblings. The color mix and the kid-friendly age range make it the friendlier choice when the users are young.
Who should skip it: if you need to outfit an entire lab or a large testing session, 10 units will not cover it, and you would be buying multiple sets. If you want every headset to look identical for inventory simplicity, the 10-color approach works against you.
• Best for large group distribution → Yunsailing 30. 30 units, each individually sealed in an OPP bag.
• Best for young children → OSSZIT Kids Headphones Bulk. Stated age range includes kid and teen.
• Best for older students and adult learners → Yunsailing 30. Stated for users aged 14 and above.
• Best for color-coded ownership → OSSZIT Kids Headphones Bulk. 10 colors in a 10-pack.
• Best for a whole lab or department → Yunsailing 30. The 30-piece count matches high-traffic, rotating-user spaces.
• Best for a single classroom or small group → OSSZIT Kids Headphones Bulk. 10 units is a realistic size for one room.
• Best for stated warranty and support → OSSZIT Kids Headphones Bulk. A listed 1-year warranty and a stated 12-hour reply window.
• Best for cable and shell durability language → Yunsailing 30. ABS shell with a 1.2 m PVC cable described as tangle-resistant for frequent handling.
In my opinion, the deciding question is how many people you are equipping and how old they are. If you are outfitting a lab, library or testing space with older students, I would buy the Yunsailing 30 — the individually bagged 30-pack and the 1.2 m cable make day-to-day management noticeably easier, and the ABS build is pitched at exactly that kind of repeated handling. If you are a teacher or parent with a smaller group of younger kids, I would buy the OSSZIT Kids Headphones Bulk instead: 10 colors, a kid-to-adult age range, and a stated 1-year warranty suit that job better. Both use a plain 3.5 mm jack and on-ear cups, so neither locks you into anything unusual.
how to wear over the ear headphones
On-ear headphones rest against the outside of your ear rather than cupping around it. Set the adjustable headband so the cushions sit flat against each ear, then use the volume control to set a comfortable level. For the Yunsailing 30, the adjustable headband and soft ear cushions are designed to keep that fit secure during long sessions.
how to clean on ear headphones
Wipe the ear cushions and the outer shell with a soft, slightly damp cloth, and avoid soaking the cable or the 3.5 mm plug. The Yunsailing 30's ABS shell and PVC cable are built for frequent handling in shared spaces, and its individually sealed OPP bags help keep each headset separate between uses. For the OSSZIT set, the same gentle wipe-down approach suits its plastic enclosure.
how to clean over the ear headphones
Even though both sets here are on-ear, the routine is similar: wipe the cushions and headband, keep moisture away from the driver and jack, and let everything air-dry before storage. Neither set lists a removable or replaceable ear cushion, so treat the pads gently and store the headphones where the cable will not be crushed.
The Yunsailing 30 is a 30-piece set for users aged 14 and above. The OSSZIT Kids Headphones Bulk is a 10-piece set with a stated age range of kid, teen and adult, in 10 colors. Choose by headcount and by who is actually wearing them — and check the current price on Amazon for each before deciding.
