• XOSDA 25 biggest strength: 25 individually bagged headphones in 12 colors with a reinforced 3.5mm plug that works with essentially any classroom device.
• XOSDA 25 biggest trade-off: The 3.5mm jack is increasingly the "old" connector — newer USB-C-only tablets and laptops need an adapter.
• ZXQZYM 20 biggest strength: A native USB-C connector that plugs straight into modern Chromebooks, tablets and laptops with no dongle to lose.
• ZXQZYM 20 biggest trade-off: Only 20 units in one color, and no 3.5mm option for older desktops or audio gear.
• Pick XOSDA 25 if you're outfitting a mixed-device classroom and want spares, color coding, and the broadest plug compatibility.
• Pick ZXQZYM 20 if your school standardized on USB-C hardware and you want one consistent connector for testing and lessons.
The XOSDA 25 is built around one idea: get a lot of headsets into a lot of hands without headaches. You get 25 on-ear headphones, each individually bagged, spread across 12 colors. That color spread matters more than it sounds — teachers use color to assign seats, group students, or spot which headset belongs to which cart at the end of the period. The retractable headband and 90-degree swivel ear cups make storage and adjustment quick, which is exactly what you want when thirty kids are grabbing gear at once.
On the spec side, these are 32-ohm dynamic drivers with a frequency range of 80–18,000 Hz and 91 dB sensitivity — an easy load for phones, laptops and tablets to drive, tuned for clear voice and general listening rather than deep bass. The build is plastic with soft silicone ear cushions, and the 3.5mm plug is reinforced, which is the part that usually fails first on classroom headphones. The 3.5mm jack is the real story here: it fits desktop computers, laptops, Chromebooks, tablets, smartphones and audio devices, so a mixed cart of older and newer machines is not a problem.
Buy it if you're a teacher, IT coordinator or parent buying for a whole group and you want maximum flexibility plus a few extra units as backups. Skip it if every device in your building is USB-C-only — you'd be adding adapters into the mix, and those get lost. Also skip it if you want a uniform look; 12 colors is a feature for organization, not for matching.
The ZXQZYM 20 takes the opposite bet: one connector, done right. Every headphone in the pack uses a standard USB-C plug, which means it connects directly to USB-C Chromebooks, laptops and tablets without an adapter. For schools that have refreshed their hardware, that's a genuine operational win — no dongles to hand out, collect, replace or troubleshoot. The set ships as 20 individually packaged black on-ear headphones, which keeps distribution and inventory simple.
Comfort follows the same practical logic: a lightweight on-ear frame, soft ear cushions and an adjustable headband that fits kids, teens and adults for longer sessions. The 32-ohm impedance matches the XOSDA, so these are similarly easy to drive from a laptop or tablet headphone output. The focus is on crisp, clear audio for lectures, language-learning audio and exam prompts rather than music-heavy listening — which is the right target for testing centers and computer labs. The build uses a sturdy structure with reinforced cables, and both brands back their headphones with a one-year warranty.
Buy it if your devices are USB-C and you want consistency across a lab, library or testing room. Skip it if you still have 3.5mm desktops, older tablets, or audio equipment in the mix — there's no 3.5mm option here, and only one color, so you can't color-code by group.
Side-by-Side: Which Should You Choose?
• Best for mixed or older device carts → XOSDA 25. The 3.5mm jack covers desktops, laptops, tablets, phones and audio gear.
• Best for large classrooms needing spares → XOSDA 25. 25 units versus 20 gives you a small buffer.
• Best for color-coded organization → XOSDA 25. 12 colors make seat and group assignment easy.
• Best for standardized, uniform sets → ZXQZYM 20. One color keeps carts and bins consistent.
• Best for testing centers and exam audio → ZXQZYM 20. The USB-C fit and clear-voice tuning suit prompt playback on modern hardware.
• Best for storage and quick adjustment → XOSDA 25. Retractable headband and 90-degree swivel ear cups fold down flat.
• Best for simple distribution → ZXQZYM 20. Individually packaged units hand out cleanly with no sorting.
• Tie on power needs → both. Both are 32-ohm wired on-ear sets with no active noise cancellation, so neither needs charging.
If I were outfitting a general classroom today, I'd buy the XOSDA 25. The 25-pack, the 12 colors and the 3.5mm plug that works with basically anything give me the most room to handle whatever devices show up — and the extra units absorb the inevitable losses. I'd choose the ZXQZYM 20 instead if my school had standardized on USB-C hardware, because skipping adapters entirely is worth more than the extra five units in that scenario. In my opinion, the connector your devices actually use should decide this, not the pack size. Check the current price on Amazon before you commit, since pack pricing shifts.
Both work, but it depends on the port. USB-C Chromebooks pair directly with the ZXQZYM 20, while 3.5mm-equipped Chromebooks and older models pair with the XOSDA 25.
Do these headphones need charging or batteries?
The ZXQZYM 20 is the more natural fit for modern testing rooms because USB-C matches current devices and the audio is tuned for clear speech. If your testing machines still use 3.5mm, go with the XOSDA 25.
Yes. XOSDA offers a one-year warranty on its headphones, and ZXQZYM lists a one-year warranty as well. Coverage terms are worth confirming with each seller.
Both are listed for kids, teens and adults, and both have adjustable headbands. The XOSDA 25 adds a retractable band and swivel ear cups, which helps with fit and storage across ages.
