• Gaosen 50 — biggest strength: 50 individually bagged pairs in mixed colors with soft silicone tips sized for small ears, so a whole classroom gets its own set.
• Gaosen 50 — biggest trade-off: it uses a standard 3.5 mm jack, so it will not plug directly into USB-C-only tablets, phones or laptops without an adapter (an adapter is not included).
• XOSDA USB C Headphones — biggest strength: a native USB-C plug with no adapter needed, plus on-ear cushions and an adjustable headband that fit a range of head shapes.
• XOSDA USB C Headphones — biggest trade-off: it is a 20-pack in black only, so you get fewer units and less color variety than the Gaosen set.
• Choose Gaosen 50 if your devices still have a headphone jack and you need maximum quantity for a classroom, a school library or a giveaway.
• Choose XOSDA USB C Headphones if your students or kids use USB-C tablets, Chromebooks or phones and you want a sturdier on-ear build.
The Gaosen 50 is a bulk pack of 50 wired in-ear earbuds, model GS01, in mixed colors. Each pair comes individually bagged and sealed, which is the detail that matters most in a school setting: you can hand one pair to one student, label it, store it, and swap it out without unpacking a shared bin. The silicone tips are described as soft and compact, aimed at small ears and students roughly aged 3 to 12, so the physical fit is designed around younger kids rather than adults.
On the technical side, the Gaosen 50 uses a 32 ohm dynamic driver with a 20 Hz to 20 kHz frequency range — a standard, undemanding spec that any phone, tablet, Chromebook, laptop or PC with a 3.5 mm jack can drive without a headphone amp. There is a media control on the cable and no active noise control, which is exactly what you would expect at this tier. The brand is Gaosen, a U.S. brand focused on kid and adult headphones, and the pack carries a one-year warranty with a stated 12-hour response window through Amazon email.
Buy it if you are outfitting a classroom, a computer lab, a testing room, a library or a camp, and your devices still have 3.5 mm jacks. The sheer count is the point — 50 pairs means replacements are built in, and mixed colors make it easy to sort by table, group or student.
Skip it if your fleet is USB-C-only. That is the one real limitation. A USB-C tablet with no headphone jack will not take these without an adapter, and if you are buying for 30 kids, that is 30 adapters to lose. Also skip it if you want on-ear or over-ear coverage rather than tips sitting in the ear canal.
The XOSDA USB C Headphones take the opposite approach. This is a 20-pack of on-ear wired headsets, model LS857C, finished in black, and the headline feature is the connector: a USB Type-C plug that goes straight into tablets, laptops, Chromebooks and phones without an adapter. For a school that has moved to USB-C devices, that removes an entire category of daily friction — no dongles, no "my headphones don't fit," just plug and play.
The build is aimed at surviving kids. The cable is described as longer and tangle-resistant, the ear cushions are soft, and the headband is adjustable to fit different head shapes — which is the practical advantage of on-ear over in-ear: one pair can fit a seven-year-old and a teenager, and it stays put during a test or a flight. The specs list 32 ohm impedance, a 20 Hz to 20 kHz frequency range, and sensitivity figures of 115 dB front and 102 dB. The listed cable length is about 4 feet (1.2 m). There is sound isolation rather than active noise cancellation, the ear cushions are a listed included item, and each headset is individually bagged. XOSDA backs it with a one-year replacement policy and the same 12-hour response commitment via Amazon email.
Buy it if your students or kids are on USB-C hardware and you want something that covers the ear instead of sitting inside it. The adjustable headband and tangle-resistant cord are the two features that decide whether a classroom set survives a semester.
Skip it if you need a high headcount per dollar of spend, want color variety to organize groups, or your devices still rely on 3.5 mm jacks. A 20-pack in black is a different job than a 50-pack in mixed colors.
Side-by-Side: Which Should You Choose?
• Best for USB-C-only devices → XOSDA USB C Headphones. Native Type-C, no adapter, no dongle drawer.
• Best for maximum headcount → Gaosen 50. 50 pairs versus 20, each individually bagged.
• Best for fit flexibility across ages → XOSDA USB C Headphones. Adjustable headband and soft on-ear cushions adapt to different head shapes.
• Best for small ears specifically → Gaosen 50. Compact silicone tips aimed at students aged 3–12.
• Best for cable durability in daily kid use → XOSDA USB C Headphones. The longer, tangle-resistant cord is the stated design goal.
• Best for color-coded organization → Gaosen 50. Mixed colors make it easy to assign pairs to tables or students.
• Best for a tidy, uniform classroom look → XOSDA USB C Headphones. All-black, consistent, easy to inventory.
In my opinion, most classroom and school buyers in 2026 should start by checking what port their devices actually have, because that single fact decides this comparison. If your students are on USB-C tablets and Chromebooks, I would buy the XOSDA USB C Headphones: plug-and-play Type-C, an adjustable on-ear fit that spans ages, a tangle-resistant cord, and a one-year replacement policy make it the more practical daily driver. I would pick the Gaosen 50 instead when the devices still have 3.5 mm jacks and the priority is sheer quantity — 50 individually bagged pairs with kid-sized tips is hard to beat for outfitting a whole room. One note on budget: I am not quoting any numbers here, so check the current price on Amazon before you commit.
Not directly. They use a standard 3.5 mm jack, so a USB-C-only tablet or phone needs a separate adapter, which is not included. If your devices have a headphone jack, they plug in and work immediately.
No. They are wired USB Type-C only, so they fit tablets, laptops, Chromebooks and phones with a USB-C port. On a 3.5 mm-only device they simply will not connect.
It depends on fit preference. The Gaosen 50 uses compact silicone tips designed for small ears and students aged roughly 3 to 12. The XOSDA uses on-ear cushions with an adjustable headband, which suits kids who dislike in-ear tips or who share headphones across ages.
Yes. Gaosen lists a one-year warranty, and XOSDA lists a one-year replacement policy. Both direct you to contact them through Amazon email, with a stated 12-hour response window.
