How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the tougher, thicker-cabled set built to survive a whole class of kids grabbing and yanking, choose CN-Outlet Classroom Headphones Bulk; if you need a bigger count in one box with bright mixed colors and a longer cord, choose Gaosen 20.
• CN-Outlet's biggest strength: A 3.0MM super-thick cable and reinforced plug designed against the number-one failure point on cheap school headphones — the wire.
• CN-Outlet's biggest trade-off: You get 10 pairs, and every pair is plain black, so there's nothing visually exciting for younger kids.
• Gaosen 20's biggest strength: Double the count — 20 pairs in one box — in mixed bright colors, with a longer 4-foot cord and a 115 dB sensitivity rating.
• Gaosen 20's biggest trade-off: The cord is described as thickened rather than the heavier 3.0MM build, and the color mix means you can't hand out identical units.
• Who CN-Outlet is for: Teachers and librarians who want a durable, no-fuss black set of 10 that survives daily handling.
• Who Gaosen 20 is for: Anyone outfitting a larger class or program who wants 20 pairs at once and colors kids actually notice.
The CN-Outlet set is built around one idea: the cable is where cheap headphones die, so make the cable the selling point. At 3.0MM, the cord is advertised as noticeably thicker than typical earphones, paired with a reinforced plug that CN-Outlet says holds a stable connection after repeated plugging and unplugging. In a classroom, that's the failure that ends a headphone's life — kids wrapping cords around their fingers, stuffing them in bins, tugging them off desks. A heavier cord is a real, practical answer to that problem.
The rest of the design is deliberately plain. Each pair is on-ear with an over-ear cup shape, an adjustable headband rated for kids through adults, and ABS plastic that the brand describes as light, portable and resistant to fading or cracking. The cable runs about 48 inches to a standard 3.5mm jack, so it works with phones, laptops, tablets, computers and MP3 players. Audio is 32-ohm impedance with a 20 Hz–20 kHz range and dynamic drivers — normal, sensible specs for spoken-word testing and light music. You get 10 pairs, each individually bagged, in black only, with a one-year warranty.
I'd point a teacher or librarian here if the goal is a dependable, uniform set where durability matters more than looks. I'd skip it if you need to outfit 20+ students from a single purchase, or if you're working with very young kids who respond better to color. Black is practical and easy to keep track of — but it isn't fun.
Gaosen's pitch is volume and appeal: 20 pairs in one box, in mixed bright colors, at 32 ohms with 40mm dynamic drivers, a 20 Hz–20 kHz range and a 115 dB sensitivity rating. That last figure is worth noting — higher sensitivity generally means the headphones get louder from the same device volume, which can help in a noisy room or with weaker headphone outputs on budget laptops and tablets. The cord is 4 feet, a bit longer than CN-Outlet's 48 inches, which gives students more slack at a desk.
Comfort is clearly the focus here. The cups are on-ear with soft foam cushions, the headband adjusts to fit different head shapes, and Gaosen describes the frame as flexible plastic that can bend at a large angle without breaking. Swivel cups are mentioned as part of the design, which helps them sit flat and travel well. The 3.5mm plug is listed as compatible with smartphones, iPads, Chromebooks, laptops, PCs, Android tablets, MP3 players and fitness equipment. There's a one-year warranty, and Gaosen says it answers questions within 12 hours through Amazon messaging.
The trade-offs are honest ones. Mixed colors look great to kids but mean you can't treat the set as identical units — some students will want a specific color. And while the cord is described as thickened, it isn't marketed with a specific thickness figure like CN-Outlet's 3.0MM, so on paper CN-Outlet makes the stronger durability claim. If you're buying for a larger group, a kindergarten, a library program or a family with several kids, the 20-count and the color variety are the reasons to pick this one.
Side-by-Side: Which Should You Choose?
• Best for cable durability → CN-Outlet Classroom Headphones Bulk. The 3.0MM super-thick cable and reinforced plug are the headline feature.
• Best for younger kids → Gaosen 20. Bright mixed colors and soft foam cushions are aimed squarely at children.
• Best for a uniform, easy-to-manage set → CN-Outlet Classroom Headphones Bulk. All black, all identical, individually bagged.
• Best for longer reach at a desk → Gaosen 20. A 4-foot cord beats CN-Outlet's roughly 48 inches.
• Best for loud, clear output on weak devices → Gaosen 20. The 115 dB sensitivity rating is the standout audio figure between the two.
• Best for lighter weight per pair → CN-Outlet Classroom Headphones Bulk. The 10-pack ships at 0.54 kg total versus 1.25 kg for the 20-pack.
• Best for testing and quiet focus → either. Both use 3.5mm wired connections, 32-ohm impedance and a 20 Hz–20 kHz range with dynamic drivers.
In my opinion, most classroom buyers should start with the CN-Outlet Classroom Headphones Bulk. The 3.0MM cable attacks the single most common reason school headphones get thrown away, and a set of 10 identical black pairs is easy to store, hand out and replace. That said, if you're equipping a bigger room or working with small children, I'd choose the Gaosen 20 instead — 20 pairs, bright colors, a longer cord and higher sensitivity are genuinely useful advantages, and the flexible frame is built for the way kids actually treat gear. Match the count and the audience to your room, and either set will do the job.
It depends on your headcount. Gaosen gives you twice the pairs, a longer cord and a higher 115 dB sensitivity rating. CN-Outlet counters with a thicker 3.0MM cable and a uniform black set. For 10 students, I'd take CN-Outlet; for 20, Gaosen.
Both list 32-ohm impedance, dynamic drivers and a 20 Hz–20 kHz range, so they're in the same class. Gaosen adds a 115 dB sensitivity figure, which suggests it plays louder from the same device. For spoken-word testing and light music, either is fine.
Yes — both use a standard 3.5mm jack. CN-Outlet lists phones, laptops, tablets, computers and MP3 players; Gaosen lists smartphones, iPads, Chromebooks, laptops, PCs, Android tablets, MP3 players and fitness equipment.
On paper, CN-Outlet makes the stronger claim with its 3.0MM super-thick cable and reinforced plug. Gaosen emphasizes a flexible plastic frame that bends at a large angle plus a thickened cord. Both carry a one-year warranty. For pricing, check the current price on Amazon using the button on this page.
