How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a whole classroom's worth of simple, tough, wired on-ear headphones in one box, choose OSSZIT Kids Headphones Bulk; if you need a single grown-up on-ear headphone with a USB-C connection, a mic and a more refined build for music and studio-style listening, choose AIAIAI Tracks Black USB-C.
• OSSZIT Kids Headphones Bulk — biggest strength: a 10-pack of on-ear, wired 3.5mm headphones in 10 colors, built for classrooms and shared student use.
• OSSZIT Kids Headphones Bulk — biggest trade-off: basic plastic build, no microphone, no noise control, and it works only over a 3.5mm jack.
• AIAIAI Tracks Black USB-C — biggest strength: 40mm dynamic drivers, full-spectrum tuning with tight bass and detailed highs, a stainless steel enclosure, and a 3-button remote with mic over USB-C.
• AIAIAI Tracks Black USB-C — biggest trade-off: it's a single pair aimed at adults, with no 3.5mm option and no noise control.
• Buy OSSZIT if you're outfitting a class, a school lab or a group of kids and need many pairs at once.
• Buy AIAIAI Tracks if you're one listener who wants an on-ear headphone for music, studio-style work and calls on a USB-C device.
This one is a volume play, and that's the whole point. OSSZIT sells the model OSSZIT101 as a 10-pack of wired on-ear headphones in 10 different colors, with a 3.5mm jack and a 32 ohm impedance rating. In plain terms: it's designed for a room full of students, not for one person who cares about sound quality above all else.
The feature list reads like a classroom checklist. It works with 3.5mm jacks on desktop computers, laptops, Chromebooks, tablets, smartphones and other audio devices. The build uses stronger wires, plastics and 3.5mm connectors, which is exactly the kind of reinforcement that matters when headphones get handed out, plugged in, yanked out and dropped by kids all day. There's a volume control on a remote on the cable, so a student can adjust level without touching the source device. The age range is listed as kid, teen and adult, and the manufacturer backs it with a 1-year warranty.
Who should buy it? Teachers, school IT staff, homeschool parents, after-school programs, libraries and anyone setting up a listening station or a computer lab where several people need their own pair at the same time. The 10 colors are a genuinely practical touch — they make it obvious whose pair is whose, which cuts down on mix-ups. The lightweight on-ear fit and plastic enclosure keep it easy to carry between rooms.
Who should skip it? Anyone who wants a microphone for calls or online classes with voice, anyone who needs USB-C, and anyone who wants noise cancellation or a more premium feel. There's no mic and no noise control here. It's also a wired-only design, with no wireless technology at all. If you need one good pair for yourself instead of ten pairs for a group, this isn't the shape of product you're after.
AIAIAI Tracks is the opposite approach: one pair, built around a specific listener. It's a wired on-ear headphone with a USB-C connection, a round earpiece shape, and a stainless steel enclosure in black. The spec sheet lists 40mm dynamic drivers, a 32 ohm impedance, and a frequency range of 20 Hz to 20,000 Hz — the full audible spectrum, which is why the marketing language around it talks about tight bass, full-spectrum sound and detailed highs.
The control story is more complete than the OSSZIT's. There's a 3-button remote and mic on board, with media control handled by onboard buttons on the remote, and the listing mentions three power levels. That combination is what makes it a headphone you can actually take a call on, skip tracks with, and use as your daily wired set without reaching for your phone every time. The theme is music and studio recording, and the adjustable two-color slider on the aluminium band is a fit detail aimed at people who wear one pair for hours.
Who should buy it? An adult who wants an on-ear headphone for music listening, casual studio-style work and voice calls, on a device with USB-C — a modern laptop, a tablet, a phone with a USB-C port. If you care about driver size and frequency range as a rough proxy for how much detail a headphone can reproduce, the 40mm dynamic driver here is the more serious audio component of the two.
Who should skip it? Anyone with only a 3.5mm output and no adapter, since USB-C is the only connection listed. Anyone buying for young kids, since the age range is listed as adult. And anyone who needs active noise cancellation — there's none, same as the OSSZIT. It's also a single unit, not a set, so it solves a personal problem, not a classroom one.
• Best for classrooms and group buying → OSSZIT Kids Headphones Bulk. Ten on-ear pairs, ten colors, one box.
• Best for audio quality and detail → AIAIAI Tracks Black USB-C. 40mm dynamic drivers and a 20 Hz–20,000 Hz range versus a basic on-ear design.
• Best for calls and voice → AIAIAI Tracks Black USB-C. It has a built-in mic and a 3-button remote; the OSSZIT has no microphone.
• Best for device compatibility across old and new gear → OSSZIT Kids Headphones Bulk. The 3.5mm jack fits desktops, laptops, Chromebooks, tablets, smartphones and other audio devices.
• Best for USB-C devices → AIAIAI Tracks Black USB-C. That's the only connection it offers.
• Best for build materials → AIAIAI Tracks Black USB-C. Stainless steel enclosure and an aluminium band, versus plastic on the OSSZIT.
• Best for young kids → OSSZIT Kids Headphones Bulk. Its stated age range covers kid and teen; the AIAIAI is listed for adults.
• Best for adjusting volume at the cable → either one. Both put controls on a remote rather than the earcup.
• Best for noise control → neither. Both list noise control as none, so don't expect cancellation from either.
In my opinion, these two don't really compete for the same buyer, so the honest answer is that you should pick the one that matches your situation. If you're equipping a classroom, a lab or a group of kids, I'd buy the OSSZIT Kids Headphones Bulk — the 10-pack, the 10 colors, the reinforced wiring and connectors, and the 3.5mm compatibility are all aimed squarely at that job, and the 1-year warranty backs it up. If you're one adult who wants an on-ear headphone for music and calls on a USB-C device, I'd buy the AIAIAI Tracks Black USB-C — the 40mm drivers, stainless steel build and mic-and-remote setup are simply a more capable headphone for personal listening. Check the current price on Amazon before you decide, since that's the one thing that can tip a close call.
how to wear over the ear headphones
On-ear headphones like both of these rest against the outside of your ear rather than surrounding it, so the earcups sit flat on the ear and the band runs over the top of your head. Adjust the band or slider so the cups press lightly and evenly on both ears — the AIAIAI Tracks has an adjustable slider for exactly this. If one side feels tighter, the fit is off, not the headphone.
how to clean on ear headphones
Because on-ear cups touch your ears directly, they pick up skin oils and dust. Wipe the earcups and the band with a soft, slightly damp cloth, and keep liquid away from the drivers and the cable connectors. For the OSSZIT's 3.5mm plug and the AIAIAI's USB-C connector, a dry soft brush or a dry cloth is the safer choice — never soak the connectors or the remote housing.
how to clean over the ear headphones
If you're comparing these to over-ear models, the cleaning logic is similar but the surface area is larger: wipe the earpads and headband, and clean around the hinges and sliders where grime collects. On both headphones in this comparison the enclosure is a solid material — plastic on the OSSZIT, stainless steel on the AIAIAI — so a gentle wipe is all either needs. Skip harsh solvents, which can damage coatings and pad material.
No. Both the OSSZIT Kids Headphones Bulk and the AIAIAI Tracks Black USB-C list noise control as none. That means you get passive isolation only, from how well the on-ear cups sit against your ears. Neither one actively cancels background sound, so if you need that feature specifically, you'd be looking at a different category of headphone.
