If you want the larger classroom set with a brighter, kid-friendly look and 40mm drivers, choose Gaosen 20; if you need individually sealed packs, leather ear cushions and sound isolation in a smaller, black set, choose XOSDA 10.
• Gaosen 20 — biggest strength: 20 pairs in one box with 40mm dynamic drivers, a 4-foot cord, flexible bendable headbands and mixed bright colors that suit a whole class at once.
• Gaosen 20 — biggest trade-off: No noise control at all, and the mixed-color look is not something you can switch off if you want a uniform black set.
• XOSDA 10 — biggest strength: Each pair is individually bagged and sealed, with leather ear cushions, a reinforced 3.5mm jack and sound isolation for quieter focus.
• XOSDA 10 — biggest trade-off: Half the pairs of the Gaosen set, only in black, and no 40mm driver figure or frequency range is stated.
• Who Gaosen 20 is for: Teachers or program leads who need a big, colorful class set in one purchase and value a stated driver size.
• Who XOSDA 10 is for: Teachers, tutors or small programs who want sealed individual packs, a more muted look and a bit of passive noise blocking.
The Gaosen 20 is built around one idea: getting a full classroom outfitted in a single purchase. You get 20 on-ear pairs in mixed colors, so handing them out, spotting which one belongs to which desk, and keeping track of the set is easier than with a uniform pile of identical black headphones. The bright color mix is the practical part here — it is not just decoration, it makes a class set easier to manage.
On the spec sheet, the audio side is the most detailed of the two: 40mm dynamic drivers, a 20 Hz to 20KHz frequency range, 32 ohm impedance and 115 dB sensitivity. In plain terms, that is a normal, easy-to-drive wired headphone that most phones, tablets, Chromebooks, laptops and PCs will handle without any extra amp. The 4-foot cord is a sensible middle length for desk work, and the 3.5mm plug covers the devices schools actually use — Chromebooks, iPads, Android tablets, laptops, desktops and MP3 players.
Who should skip it? If you need a specific, uniform color for a school dress code or a branded program, the mixed-color pack works against you. And if quiet isolation matters — testing rooms, busy shared spaces — note that Gaosen lists noise control as None. These are open, on-ear headphones; they play sound, they do not block it.
XOSDA 10: Who It's For
The XOSDA 10 takes the opposite approach: a smaller set with more individual handling. You get 10 pairs, all black, and each one is individually packaged and sealed. That detail matters more than it sounds. If you are handing headphones out to students, storing spares, or running a program where hygiene and "this one is unused" matter, sealed individual packs are a real advantage over a bulk box of loose pairs.
Comfort is the other clear focus. XOSDA uses soft leather ear cushions on a swivel cup design with an adjustable headband, and describes the fit as secure without pinching, sized for kids through adults. The material list backs that up — leather and plastic — so the contact surface is a step up from plain foam if you care about how they feel over a long session. XOSDA also lists sound isolation as the noise control type, which is worth noting: it is passive blocking from the cushion seal, not active noise cancellation, but it does mean a bit less outside noise leaking in and out compared to an open on-ear design.
The audio spec sheet is thinner here — 32 ohm impedance and a reinforced 3.5mm jack, with no driver size or frequency range stated. So the honest read is: same impedance class as the Gaosen, universal 3.5mm compatibility with smartphones, tablets, laptops, Chromebooks and computers, and a connector that is reinforced specifically because that is the failure point on cheap wired headphones. The brand also offers this model in larger pack sizes, which tells you the design is meant to scale across a school or a learning center.
Who should skip it? If you need 20+ pairs right now in one order, this set only gets you 10. If you want color variety, there is none — it is black only. And if you specifically want the larger 40mm driver and full frequency range documented, XOSDA does not publish those figures, so you would be buying on comfort, packaging and build claims instead.
• Best for a large class in one purchase → Gaosen 20. 20 pairs versus 10 means fewer orders and fewer mismatched sets.
• Best for hygiene and easy storage → XOSDA 10. Each pair arrives individually sealed, which is much easier to hand out and keep track of.
• Best documented audio specs → Gaosen 20. 40mm dynamic drivers, 20 Hz–20KHz range, 115 dB sensitivity and 32 ohm impedance are all stated.
• Best comfort material → XOSDA 10. Leather ear cushions with swivel cups versus Gaosen's soft foam.
• Best for quieter focus → XOSDA 10. It lists sound isolation; Gaosen lists noise control as None.
• Best for a colorful, kid-friendly look → Gaosen 20. The mixed-color pack is easier for young students to claim and identify.
• Best for durability claims → close call. Gaosen emphasizes a bendable bracket and thickened cord; XOSDA emphasizes a reinforced jack and long-haul materials.
• Best for a uniform, professional look → XOSDA 10. All black, no color variation.
If I were outfitting a full classroom or a program with 20+ students, I would buy the Gaosen 20. The math is simple: one order, one set, mixed colors that make classroom management easier, and the only pair here with a documented 40mm driver and full frequency range. The flexible bracket and thickened cord are the right priorities for something students will bend, drop and yank every day.
But if I were running a smaller group — a tutoring room, a family, a rotating testing station — I would pick the XOSDA 10. Individually sealed packs, leather cushions and passive sound isolation are genuinely better for shared, hand-to-hand use. In my opinion, that is the smarter pick when hygiene and comfort matter more than sheer quantity.
For a full class, the Gaosen 20 fits better because you get 20 pairs in one set with mixed colors and a documented 40mm driver. The XOSDA 10 only gives you 10 pairs, though it does come in larger pack sizes if you want to scale up.
Neither one has active noise cancellation. The Gaosen 20 lists noise control as None, while the XOSDA 10 lists sound isolation, which is passive blocking from the leather ear cushion seal — helpful in a noisy room, but not the same as ANC.
Yes. Both use a standard 3.5mm wired jack. Gaosen lists compatibility with smartphones, iPads, Chromebooks, laptops, PCs, Android tablets and MP3 players, and XOSDA lists smartphones, tablets, laptops, Chromebooks and computers.
