• rockpapa L22 — biggest strength: a 40mm dynamic driver tuned for stereo bass and clear mids, plus a built-in microphone and remote call control, so one kid can listen and talk on a single 3.5mm wired pair.
• rockpapa L22 — biggest trade-off: it is one headphone, not a set, and it leans on sound quality and comfort rather than classroom indestructibility.
• Hengliyuan Kids Headphones Bulk — biggest strength: eight pairs in eight colors, each individually wrapped and sealed, with reinforced 3.5mm plugs and a 1.2 m cable built for shared, repeated classroom use.
• Hengliyuan Kids Headphones Bulk — biggest trade-off: there is no microphone on the spec sheet and no stated driver size, so it is a listening-first, quantity-first buy rather than an audio-first one.
• Who each pick is for: rockpapa L22 for one child who wants music, videos and calls on a foldable on-ear pair; Hengliyuan for teachers, schools, tutors or families who need a stack of ready-to-hand-out headphones.
The rockpapa L22 is built around a 40mm dynamic driver with a 20–20000 Hz frequency range, 32 ohm impedance and 102 dB sensitivity. In plain terms, that is a wired on-ear headphone designed to run loudly and easily off a phone, tablet, Chromebook or laptop without needing a separate amp. The tuning is aimed at stereo bass with crisp midrange, so music and video sound fuller than the thin, tinny output a lot of cheap kids' headphones produce.
The physical design is the other half of the story. It uses soft ear cushions and an adjustable headband, and the whole thing folds up, which matters if it lives in a backpack, a desk drawer or an airplane seat pocket. There is a built-in microphone with remote call control on the cable, so it doubles as a headset for online classes, video calls and voice chat. It is aimed at kids over four years old, and it comes as a single pair in a gradient purple finish.
I would buy this one for a child who actually uses headphones — listening to music, watching shows on a tablet, joining a class, taking a call. I would skip it if you are trying to supply a group, because one pair cannot do that job, and I would also skip it if you want the toughest possible classroom hardware, since its focus is sound and comfort rather than bulk durability.
Hengliyuan's set is a different product category wearing the same "kids headphones" label. You get eight pairs in eight colors — red, orange, yellow, light blue, dark blue, pink, white and black — and each one arrives individually wrapped and sealed. That single detail is why this set exists: it can be handed out, stored and restocked without the tangle of unboxed headphones sitting in a bin.
The classroom intent shows in the build choices. The cable is 1.2 m (about 47 inches) of sturdy PVC, which gives kids room to move without yanking the plug out, and the 3.5mm plug uses a reinforcement process the brand says extends usable life by at least six to twelve months. The headband is retractable so it fits both adult and child head shapes, the earcups swivel for easy packing, and the sponge cushions are there for long sitting sessions. Impedance is 32 ohm, matching the rockpapa, but sensitivity is lower at 92 dB and no driver size is listed.
The spec sheet also notes a 1 year warranty and a media control on the cable. There is no microphone listed, so treat this as a listening set, not a headset for talking. I would buy this for a teacher, a school, a tutor running small groups, or a parent with several kids who all need their own pair and their own color.
• Best for sound quality and bass → rockpapa L22. A 40mm dynamic driver and 102 dB sensitivity give it the edge for fuller, louder listening.
• Best for microphone and calls → rockpapa L22. It has a built-in mic and remote call control; the Hengliyuan sheet lists no microphone.
• Best for equipping a group → Hengliyuan Kids Headphones Bulk. Eight sealed pairs in eight colors is the whole point.
• Best for classroom and school use → Hengliyuan Kids Headphones Bulk. Reinforced 3.5mm plugs, a long PVC cable and a retractable, swivel-cup design are aimed squarely at shared use.
• Best for travel and packing → rockpapa L22. Its foldable design and lightweight build suit a backpack or carry-on; the Hengliyuan set is bulky by nature because it is eight pairs.
• Best for mixed ages in one household → Hengliyuan Kids Headphones Bulk. The adjustable headband is described as fitting both adult and child head shapes.
• Best for warranty reassurance → Hengliyuan Kids Headphones Bulk. It carries a 1 year warranty; the rockpapa sheet does not list one.
• Best for a single kid who wants one pair → rockpapa L22. Buy one, not eight.
In my opinion, most people searching these two names are solving one of two very different problems, and the answer is not close either way.
If you are buying for one child — music, videos, online class, the occasional call — I would buy the rockpapa L22. The 40mm driver, the 102 dB sensitivity, the built-in mic and the foldable on-ear design make it the more complete headphone for one person.
If you are buying for a classroom, a tutoring group or several kids at once, I would buy the Hengliyuan Kids Headphones Bulk set. Eight sealed pairs, reinforced plugs and a retractable, swivel-cup build are exactly what shared use demands, and the 1 year warranty backs it up.
are on ear headphones good
On-ear headphones rest on the ear rather than around it, which makes them lighter and easier to fold and carry than over-ear models. Both headphones here are listed as on-ear, and both use 32 ohm impedance, so they are easy to drive from a phone, tablet or Chromebook. The trade-off is less passive isolation than a full over-ear cup, though both list sound isolation as a feature.
what are the best open ear headphones
Neither product here is an open-ear design — both are on-ear headphones with cushions that sit against the ear. If open-ear is what you specifically want, neither of these two is the right pick, and you should look at that category separately. These are traditional wired on-ear headphones with 3.5mm plugs.
which are the best over the ear headphones
If you specifically want over-ear, note that the rockpapa L22 lists on-ear placement but an over-ear earpiece shape, while the Hengliyuan set lists on-ear placement with round earpieces. For a true over-ear fit with the fullest sound, the rockpapa L22's 40mm driver gives it the advantage of the two. Which one is "best" still depends on whether you need one pair or eight.
what are the best over the ear headphones to buy
There is no single answer without knowing your use case. For one child who needs a mic and fuller bass, the rockpapa L22 fits better. For a school or group that needs eight usable pairs with reinforced plugs and a 1 year warranty, the Hengliyuan bulk set fits better. Check the current price on Amazon for each before deciding, since value depends on what you are paying at the time.
