How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single lightweight folding headphone built for assisted-listening and hygiene-focused shared use, choose Williams AV Sound HED 021; if you need a classroom-ready set of wired USB-C on-ear headphones for kids and testing stations, choose ZXQZYM USB C Headphones.
• Williams AV Sound HED 021 — biggest strength: it folds down into a compact package (roughly 6-7/8" x 5-5/8" x 7/8" folded) and is built around a 32 Ω mono driver aimed at mild, low-gain hearing loss.
• Williams AV Sound HED 021 — biggest trade-off: it ships as a single adult-size headphone with no USB-C connectivity, and its headline accessory is a 100-pack of replacement sanitary covers rather than a full classroom bundle.
• ZXQZYM USB C Headphones — biggest strength: a 10-pack of wired USB-C on-ear headphones with an adjustable headband, soft earpads, a 4.5 ft tangle-resistant cable, and mixed colors — designed for class sets and school testing.
• ZXQZYM USB C Headphones — biggest trade-off: no noise control at all, and it's a plug-in USB-C only headphone, so anything without a USB-C port is out.
• Pick Williams AV Sound HED 021 if you need one durable folding headphone for an adult in a listening-assistance setting.
• Pick ZXQZYM USB C Headphones if you need to outfit many kids at once with USB-C wired headphones.
The HED 021 is a folding, adult-size headphone with a 32 Ω mono driver. That mono detail matters more than it looks: mono output sends the same signal to both ears, which is exactly what you want when the priority is hearing one clear voice — a speaker, an announcer, a tour guide, a service desk — rather than stereo music imaging. The "mild and low gain hearing loss" rating tells you the intended listener, too. This is not a bass-forward music headphone; it's a speech-and-clarity tool.
The folding design is the real selling point here. At roughly 6-7/8" x 5-5/8" x 7/8" folded and 0.12 lbs, it collapses into something you can tuck into a drawer, a carry pouch, or a facility cabinet without eating much space. If you manage a room full of these — a theater, an auditorium, a house of worship, a clinic waiting area — that foldability plus the low weight makes storage and hand-out genuinely easier.
ZXQZYM USB C Headphones: Who It's For
The ZXQZYM set is a 10-pack of wired USB-C on-ear headphones with mixed colors, and the framing is unmistakable: classroom, school, kids. The 4.5 ft cable is a deliberate choice — long enough to reach from a desk to a laptop or tablet without dangling to the floor, short enough to reduce the tangling chaos that eats up class time. The cable is described as tangle-resistant, which is the single most practical spec on this list if you've ever untangled a bin of student headphones.
Comfort and fit get real attention in the design. The headband is adjustable and the earpads are soft, with an age range covering kids, teens, and adults. That adjustability is what lets one bulk set serve a mixed-age classroom instead of forcing you to buy separate sizes. The 32 Ω impedance matches the Williams unit, meaning it's an easy load for the kind of devices schools actually use.
Connectivity is where this set draws its line in the sand. It's USB Type C, wired, no adapter mentioned, and compatibility is listed for tablets, PCs, desktops, laptops, Chromebooks, and fitness equipment. That's a broad list, but it's all USB-C. Buy it if you're equipping a class set, a testing lab, or a group of kids and you want one bulk purchase with adjustable fit, durable cables, and mixed colors so students can spot their own pair. Skip it if your devices are older USB-A or 3.5 mm only, if you need noise cancellation (there is none here), or if you only need a single headphone — a 10-pack is the whole point. There's also a 1-year warranty listed, which is a reasonable safety net for gear that gets handed around by children.
Side-by-Side: Which Should You Choose?
• Best for shared-listening and hygiene protocols → Williams AV Sound HED 021 — sanitary covers in a 100-pack plus replaceable earpads are built for hand-off between users.
• Best for portability and storage → Williams AV Sound HED 021 — it folds to roughly 6-7/8" x 5-5/8" x 7/8" and weighs about 0.12 lbs.
• Best for modern device compatibility → ZXQZYM USB C Headphones — USB Type C wired connection listed for tablets, Chromebooks, laptops, desktops, PCs, and fitness equipment.
• Best for adult hearing-assistance use → Williams AV Sound HED 021 — adult size, mono, 32 Ω, rated for mild and low-gain hearing loss.
• Best for kids and mixed-age rooms → ZXQZYM USB C Headphones — soft earpads and an adjustable headband across a kid/teen/adult range.
• Best if you need noise cancellation → neither — the ZXQZYM set explicitly lists no noise control, and the Williams unit is a speech-focused mono headphone.
• Best if you need a single unit rather than a set → Williams AV Sound HED 021 — the ZXQZYM listing is a 10-pack, so it's overkill for one listener.
In my opinion, these two barely overlap in purpose, so the decision comes down to what you're actually outfitting. If I were setting up a shared-listening space for adults — a facility, an auditorium, a service counter — I'd buy the Williams AV Sound HED 021. The foldable frame, light weight, mono clarity, and the replaceable covers and pads make it the more sensible long-term choice for that job.
If I were equipping children in a classroom, I'd buy the ZXQZYM USB C Headphones. Ten adjustable USB-C pairs with tangle-resistant cables is exactly the shape of a school purchase, and the mixed colors help students keep track of their own. My honest pick for most readers is the ZXQZYM set, because bulk classroom and testing use is the more common need — but if foldable adult listening gear is what you're after, the Williams AV unit wins that category outright. Check the current price on Amazon for whichever one matches your setup.
FAQ
are on ear headphones good
what are the best open ear headphones
Open-ear and on-ear are different things, and neither product here is an open-ear design — the Williams AV unit is a folding on-ear headphone and the ZXQZYM set is explicitly on-ear. If you specifically want open-ear, you'd need to look at a different category. If what you actually want is a light, breathable on-ear fit for speech clarity, the Williams AV Sound HED 021 is the one I'd point to.
which are the best over the ear headphones
Over-ear headphones fully surround the ear, which is not what either of these does — this comparison is on-ear versus on-ear. The Williams AV Sound HED 021 is adult-size and folds down small, while the ZXQZYM set is a 10-pack sized for kids through adults. If over-ear is a hard requirement, neither of these is the right match.
what are the best over the ear headphones to buy
I can only speak to what the specs show here, and both of these are on-ear rather than over-ear. Between the two, the Williams AV Sound HED 021 suits an adult who wants a foldable, mono, speech-focused headphone, and the ZXQZYM USB C Headphones suit a school buying a bulk USB-C class set with adjustable fit. Decide which of those describes you, then check the current price on Amazon.
