If you want a white, no-nonsense on-ear headset built for shared adult learning spaces and easy bulk distribution, choose Yunsailing 30; if you need a colorful classroom set aimed at kids with a braced, bendable frame and a one-year warranty, choose Gaosen Bulk Class Set.
• Yunsailing 30 biggest strength: 30 individually OPP-wrapped white headsets with an ABS shell and a 1.2 m tangle-resistant PVC cable — built for orderly distribution and long-term storage in labs, libraries and training rooms.
• Yunsailing 30 biggest trade-off: Plain white, adult-oriented design (ages 14+) with no published driver specs, and a shorter 1.2 m cable than Gaosen's 4 ft cord.
• Gaosen Bulk Class Set biggest strength: Kid-friendly mixed colors, soft foam cushions, a flexible plastic bracket that bends at a large angle, 40 mm dynamic drivers (32 ohm, 115 dB, 20 Hz–20 kHz) and a one-year warranty.
• Gaosen Bulk Class Set biggest trade-off: Mixed colors and kid-focused styling suit schools better than corporate or adult settings, and the ear pads are foam rather than the cushioned type Yunsailing describes.
• Pick Yunsailing 30 if you run a computer lab, library or group testing program for teens and adults and want tidy, individually wrapped units.
• Pick Gaosen Bulk Class Set if you teach younger students and want sturdy, colorful, bend-resistant headphones with a longer cable.
The Yunsailing 30 is a 30-pack of wired on-ear headphones in white, and the whole design is built around managed group use. Every headset comes sealed in its own OPP bag, which matters more than it sounds. If you hand out 30 sets a day in a lab or a testing room, loose headphones turn into a tangled pile fast. Individually wrapped units let you hand one to each user, store the rest cleanly, and keep track of what's been distributed.
The materials back that up. The shell is ABS, a hard, impact-resistant plastic, and the cable is a 1.2 m PVC cord that Yunsailing describes as tangle-resistant. In a high-traffic environment — think a school computer lab, a public library listening station, or a corporate training room — those two details are the difference between a set that survives a semester and one that doesn't. The adjustable headband and soft ear cushions are sized for extended sessions, so a student working through an online lesson or an assessment isn't fighting the fit after twenty minutes.
The 3.5 mm jack is the other practical piece. It plugs straight into laptops, desktops, tablets and most other audio devices you'd find in a modern classroom or training setup, with no adapter needed. Yunsailing lists the age range as 14 and up and the intended use as reading programs, language practice, digital lessons, multimedia projects and group testing. In my opinion, that's the clearest signal of who this is for: secondary schools, colleges, libraries and adult education programs. Skip it if you're buying for kindergarten or early elementary — the plain white look and adult-oriented framing aren't aimed at young kids. Skip it too if you want published audio specs like driver size or impedance; Yunsailing doesn't list them here.
The Gaosen Bulk Class Set takes the opposite approach. It's still a 30-pack of wired on-ear headphones with a 3.5 mm jack, but everything about the presentation says "children." The color is mixed, and Gaosen explicitly says the bright colors are meant to catch kids' attention. If you've ever tried to get a room of eight-year-olds to put headphones on without a fuss, you know why that matters. The listed age range covers kids, teens and adults, so it's flexible, but the design language is clearly school-first.
On the hardware side, Gaosen gives you more numbers than Yunsailing does. The drivers are 40 mm dynamic drivers with 32 ohm impedance, 115 dB sensitivity and a 20 Hz to 20 kHz frequency range — a full-range spec that suggests balanced, clear sound rather than bass-heavy tuning. That's the kind of profile that works for narrated lessons, testing audio and spoken-word content. The cable is a 4-foot cord, a bit longer than Yunsailing's 1.2 m, which gives kids a little more room to move at a desk without yanking the plug out.
Durability gets its own treatment here. The bracket is flexible plastic that Gaosen says can be bent at a large angle without breaking, and the ear cushions are soft foam. Anyone who has watched a child twist a headband in both directions will see the logic. Gaosen also covers the set with a one-year warranty and asks buyers to reach out through Amazon messages if anything goes wrong. That's a real point in its favor for a school buying in bulk.
The trade-offs are honest ones. Foam cushions are light and cheap to replace, but they don't have the cushioned feel Yunsailing describes, and foam tends to wear faster under heavy daily use. The kid-forward colors are an asset in a primary classroom and a liability in a boardroom or an adult training center. And while Gaosen lists a "wireless technology: FM" field, the connectivity is wired with a 3.5 mm jack — treat it as a corded headset and nothing more.

If I were outfitting a middle school, high school, college lab or library, I'd buy the Yunsailing 30. The individually wrapped packing, ABS shell, tangle-resistant 1.2 m cable and adult-oriented design solve the exact problems that come with shared headphones, and the white finish looks appropriate in any setting. If I were buying for elementary classrooms or a program where kids handle the gear roughly, I'd go with the Gaosen Bulk Class Set instead — the bendable bracket, foam cushions, mixed colors, 40 mm drivers and one-year warranty are the better fit for younger, harder-on-equipment users. Neither is a universal answer; match the set to the age group and the environment, then check the current price on Amazon before you commit.
FAQ

how to clean on ear headphones
Wipe the ear cushions and the outer shell with a soft, slightly damp cloth, then let them air dry fully before the next use. This is where the Yunsailing 30's individually wrapped packaging helps — units stay protected between sessions in shared settings. Gaosen's foam cushions should be wiped gently and never soaked, since foam breaks down faster than the cushioned pads Yunsailing describes.
