How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a class-ready wired set you can hand out by the box, choose ZXQZYM Bulk Headphones 20; if you need one adjustable headband you can wear while you sleep, run, or wear glasses without pressure, choose Mixiba 2PCS. That single split — shared 3.5mm listening versus a personal Bluetooth headband with a hook-and-loop fit — decides almost everything below. I'm framing this whole comparison around one very specific buyer: someone shopping for over-ear or on-ear headphones for glasses wearers, where temple arms and ear cushions fight for the same real estate.
• ZXQZYM Bulk Headphones 20 — biggest strength: a 20-pack of wired on-ear headphones with 4-foot cables and a 3.5mm jack, so a whole classroom or testing group gets identical, reusable units.
• ZXQZYM Bulk Headphones 20 — biggest trade-off: no wireless, no noise control, and no adjustable headband mechanism in the specs — comfort comes from soft ear cushions, not from tuning the fit.
• Mixiba 2PCS — biggest strength: an upgraded hook-and-loop headband that adjusts instantly, plus Bluetooth 5.4 and up to 14 hours of playback from a 1–2 hour charge.
• Mixiba 2PCS — biggest trade-off: no 3.5mm jack at all, so it is wireless-only, and the slim foam-padded speakers are built for resting on the ears rather than deep isolation.
• Choose ZXQZYM Bulk Headphones 20 if you are outfitting a class, a school testing session, or a group that plugs into tablets, Chromebooks, PCs, or fitness equipment.
• Choose Mixiba 2PCS if you want adjustable headphones for glasses wearers — a soft fabric band that sits around the head instead of clamping on top of your frames.
This is a volume product, and it is honest about that. You get twenty wired on-ear headphones in multi-color, each sealed in its own bag inside a carton box. For a teacher, that packaging detail matters more than it sounds: individual bags mean you can hand out units, label them, and store them back without a tangled pile. The 4-foot cable is long enough to reach a laptop or desktop without pulling, and short enough that it will not become a trip hazard across a classroom floor.
The specs are straightforward and predictable. On-ear placement with rounded earpieces, fabric and silicone enclosure materials, 32 ohm impedance, and a 20 Hz–20,000 Hz frequency range. That impedance is friendly to low-power sources — tablets, Chromebooks, desktops, fitness equipment — which is exactly the hardware list ZXQZYM names. There is a media control on the cable, and no active noise control, which is the right call for a product meant to be durable and simple rather than clever.
Who should buy it: schools, testing coordinators, libraries, workshops, and anyone who needs a stack of identical wired headphones that survive daily use. Who should skip it: if you personally want adjustable headphones for glasses wearers, this is not that product. There is no hook-and-loop fit system in the data, and no wireless mode. Twenty pairs of the same thing only makes sense if you actually have twenty listeners.
The Mixiba 2PCS is the opposite philosophy: two units, deeply personal, built around one adjustable idea. The upgraded hook-and-loop design is the headline feature and it is the reason this is the better pick for glasses wearers. You adjust the band to sit where you want it, then it stays — snug and secure without you fighting a fixed headband that presses your frames into your temples. That is the core problem with most on-ear headphones for glasses wearers, and an adjustable fabric band sidesteps it entirely.
The speaker design reinforces that. Soft, foam-padded speakers rest gently on your ears rather than pressing in, which is aimed at all-night comfort and at side sleepers. The fabric is lightweight and breathable, described as sweat-resistant, so it holds up for running, yoga, gym sessions, and meditation. Connectivity is Bluetooth 5.4 with fast pairing, and the battery is rated at up to 14 hours of playback from roughly 1–2 hours of charging. Controls are push-button on the band itself, so you can manage music and calls without taking it off.
Two practical notes from the data. First, there is no 3.5mm jack, so this is wireless-only — no wired fallback on a dead battery. Second, the headband is washable after you remove the electronic module, and hand washing is recommended to protect the fabric. You get two in the box (Black & Gray), which makes this a natural gift or a share-with-a-partner set.
Who should buy it: side sleepers, runners, gym-goers, glasses wearers who hate ear pressure, and anyone who wants adjustable headphones that disappear into a headband. Who should skip it: anyone who needs a wired 3.5mm connection, or who wants isolation from room noise — the slim foam speakers are not designed for that.
• Best for glasses wearers → Mixiba 2PCS. The hook-and-loop adjustable band lets you place the fit where your frames are not being crushed. That is the single most important difference between these two.
• Best for classrooms and group testing → ZXQZYM Bulk Headphones 20. Twenty individually bagged wired units with 4-foot cables and 3.5mm jacks that speak to tablets, Chromebooks, PCs, and desktops.
• Best for sleep and side sleeping → Mixiba 2PCS. Foam-padded speakers rest on the ears without pressure, and the fabric band is built for all-night wear.
• Best for workouts and running → Mixiba 2PCS. Breathable, sweat-resistant fabric plus a secure adjustable fit, with push-button controls you can reach mid-run.
• Best for battery life → Mixiba 2PCS. Up to 14 hours per charge, with a 1–2 hour top-up.
• Best for zero-charging reliability → ZXQZYM Bulk Headphones 20. Wired means no battery to think about, ever, which is exactly why schools keep buying 3.5mm sets.
• Best for sharing or gifting → Mixiba 2PCS. Two headbands in one box, in Black & Gray.
• Best for buying in bulk → ZXQZYM Bulk Headphones 20. There is no other way to read a 20-pack.
One honest caveat on the "adjustable" angle: ZXQZYM's adjustability is limited to how the on-ear cushions sit, while Mixiba's is an actual fit mechanism you tune by hand. If adjustability is your deciding factor, that is not a close call.
For glasses wearers, I would buy the Mixiba 2PCS. In my opinion, the hook-and-loop adjustable headband is the feature that actually solves the problem — it lets you move the pressure off your temple arms instead of accepting it — and the 14-hour battery plus Bluetooth 5.4 covers sleep, runs, and workouts without a cable. If your goal is personally comfortable adjustable over-ear or on-ear headphones for glasses wearers, that is the pick. I would only steer you to the ZXQZYM Bulk Headphones 20 if you are buying for a group, where twenty wired 3.5mm units with individually bagged packaging is the whole point. Before either, check the current price on Amazon using the button on this page, since that is the one variable that can flip a bulk buy.
It depends on the mechanism. The Mixiba 2PCS uses an upgraded hook-and-loop headband, so you loosen or tighten the band by hand until it sits snug without pressing on your ears or glasses. The ZXQZYM Bulk Headphones 20 has no headband adjustment in its specs — fit comes from the soft on-ear cushions and rounded earpieces.
The ZXQZYM Bulk Headphones 20 has a media control on the cable, so volume and playback live inline on the wire between you and your device. The Mixiba 2PCS uses push buttons on the headband, so you raise or lower volume directly from the band without touching your phone.
Neither product offers a companion EQ app or sound-tuning controls in the data. The ZXQZYM Bulk Headphones 20 covers a 20 Hz–20,000 Hz range at 32 ohm, and the Mixiba 2PCS is a Bluetooth 5.4 headband — so in both cases, "adjusting sound" means adjusting it at the source device you are paired or plugged into.
The Mixiba 2PCS is the stronger choice here, because the adjustable hook-and-loop band and foam-padded speakers reduce pressure on the ear area where glasses temples sit. The ZXQZYM Bulk Headphones 20 relies on soft ear cushions and a fixed on-ear shape, which is fine for short class sessions but less forgiving for long wear with frames.
