If you want a large classroom set in one order with mixed colors for easy student assignment, choose XOSDA 25; if you need a smaller, all-black set with a longer cable and a right-angle plug for shared tablets and laptops, choose MUMSTHT Classroom Headphones Bulk.
• XOSDA 25 — biggest strength: 25 individually bagged headphones in 12 mixed colors, so a whole class can be outfitted at once and each student can be assigned a color.
• XOSDA 25 — biggest trade-off: The 3.5 mm plug is straight rather than angled, and the cable length isn't specified, so tight tablet cases and cart storage need a little more care.
• MUMSTHT Classroom Headphones Bulk — biggest strength: A 4 ft (120 cm) cable with an L-shaped 3.5 mm plug, which is easier to route on desks and less likely to snag when devices sit in a case.
• MUMSTHT Classroom Headphones Bulk — biggest trade-off: Only 10 per pack and one color (black), so larger classes may need multiple orders and you lose any color-coding.
• Who each pick is for: XOSDA 25 for a full class, lab or library that wants maximum units per order and color variety; MUMSTHT for a smaller group, a testing station or a school that prefers a uniform look and a longer, angled cable.
The XOSDA 25 is a classroom bulk pack built around volume and variety. You get 25 on-ear headphones, each individually bagged, in a set of 12 mixed colors. That color spread is the detail that matters most in a real classroom: it makes it easy to hand out "the blue ones" to table three, label storage bins by color, or spot which headphone walked off between periods.
Comfort is clearly the design priority. XOSDA uses ultra-lightweight construction with soft silicone ear cushions, a retractable headband that adjusts for kids, teens and adults, and a 90-degree swivel ear cup for flat storage. The spec sheet lists 32 ohm impedance, 91 dB sensitivity, a dynamic driver and an 80–18,000 Hz frequency range. That lower sensitivity means it takes slightly more power to reach the same loudness as a higher-rated pair, but on a Chromebook, laptop or tablet at normal classroom volume it's more than enough. The 80 Hz bottom end is a touch rolled off, so you get clear, crisp speech and midrange rather than deep bass.
Skip it if you only need a handful of headphones, if you specifically want a uniform color, or if you need a long cable with an angled plug. Those aren't XOSDA's strengths.
MUMSTHT Classroom Headphones Bulk: Who It's For
MUMSTHT takes the opposite approach: fewer units, more attention to the cable and the plug. This is a 10-pack of on-ear headphones in black, individually packaged and sealed. The standout spec is the cable — 4 feet / 120 cm — ending in a 3.5 mm L-shaped plug. Anyone who has watched a straight plug get bent against a desk edge or a Chromebook hinge knows why that matters.
The audio numbers are slightly ahead on paper: 32 ohm impedance, 92 dB sensitivity, and a 20–20,000 Hz frequency range from a dynamic driver. That's a wider range at both ends than XOSDA's 80–18,000 Hz, and the extra dB of sensitivity means it needs marginally less power to hit the same volume. Whether a student actually hears a difference in a noisy classroom is debatable, but the specs favor MUMSTHT for fuller-range playback.
Comfort and storage follow the same playbook as most classroom headphones: swivel cups so they stack, a lightweight adjustable headband sized for kids and adults, soft ear cushions, and a bendable construction. MUMSTHT also lists sound isolation as its noise control, which helps a bit in a loud room. It carries a one-year replacement policy, and the brand offers 5- and 10-piece packs.
The trade-offs are real, though. Ten units means a 25-student class needs three orders. One color means no color-coding. And the angled plug, while great for tablets, sits a little differently in shallow recessed jacks on some older desktops.
• Best for outfitting a full class in one order → XOSDA 25 (25 units versus 10).
• Best for color-coding and quick sorting → XOSDA 25 (12 mixed colors, individually bagged).
• Best cable for desk and tablet use → MUMSTHT (4 ft / 120 cm with an L-shaped 3.5 mm plug).
• Best for a uniform, low-distraction look → MUMSTHT (all black).
• Best for slightly fuller audio range on paper → MUMSTHT (20–20,000 Hz, 92 dB versus 80–18,000 Hz, 91 dB).
• Best for stacking and compact storage → a tie — both use 90-degree swivel ear cups.
• Best for a small group, testing station or single cart → MUMSTHT (10-pack suits smaller rollouts).
• Best for shared-device durability against snagged plugs → MUMSTHT (angled plug resists bending).
• Best for a school that wants both options → buy both: XOSDA for the main classroom set, MUMSTHT for the testing room.
If I were buying for a typical classroom of 20–30 students and wanted one order to cover everyone, I'd buy the XOSDA 25. The 25-count pack, 12 colors and individually bagged units solve the two most annoying classroom problems — running short and losing track of whose headphones are whose — and the reinforced 3.5 mm connector plus retractable headband are aimed squarely at daily student abuse.
That said, if my priority were a longer cable, an angled plug that survives being yanked out of a tablet, and a uniform black set for a smaller group or a testing station, I'd pick the MUMSTHT instead. It's the more cable-focused design of the two.
FAQ
XOSDA 25, in my opinion. It ships 25 units per pack versus 10 for MUMSTHT, so a 25-student class is covered in a single order instead of three.
MUMSTHT. Its cable is listed at 4 feet / 120 cm with an L-shaped 3.5 mm plug. XOSDA doesn't specify a cable length, so MUMSTHT is the safer bet if reach matters.
Yes. Both use a standard 3.5 mm wired jack, so they work with classroom desktops, laptops, Chromebooks, tablets and phones. MUMSTHT's right-angle plug fits recessed tablet and phone cases a bit more easily.
On paper, MUMSTHT has a wider frequency range (20–20,000 Hz versus 80–18,000 Hz) and slightly higher sensitivity (92 dB versus 91 dB). Both use a 32 ohm dynamic driver, so for spoken-word lessons and testing, either is fine.
Both are sold in bulk packs, so the per-headphone value matters more than the sticker. Use the "Check latest price on Amazon" button on this page to see the current price for each pack before you decide.
