How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired on-ear headphone with a built-in sharing jack so two people can listen from one device, choose JOMILIN A10; if you need a wired on-ear headphone with a hard 84dB volume ceiling and USB-C for kids ages 2–12, choose IYGR K6C. Both fold up for travel and both are wired on-ear designs — the split is what each one is built to protect and connect.
• JOMILIN A10 biggest strength: 40 mm dynamic drivers with a 20 Hz – 20,000 Hz range, plus a sharing jack so a second pair of headphones can plug straight into it — no splitter needed.
• JOMILIN A10 biggest trade-off: It's a general-purpose 3.5 mm wired headphone with no volume limiter, so it's not the safer pick for a toddler.
• IYGR K6C biggest strength: 84dB volume-limiting that caps output for young ears, a 113 g body, and a headband with 5 size settings plus earcups that move vertically and horizontally.
• IYGR K6C biggest trade-off: USB-C only — it will not plug into a standard 3.5 mm headphone jack without the right adapter or a USB-C device.
• Who JOMILIN A10 is for: teens and adults who want one wired pair for calls, music and sharing audio with someone next to them.
• Who IYGR K6C is for: parents buying for a child roughly 2–12 who want the volume capped and the fit adjustable.
The A10 is the more grown-up of the two on paper. It runs a 40 mm dynamic driver across a 20 Hz – 20,000 Hz frequency range, which covers the full audible span — so it's designed to handle everything from bass-heavy tracks to spoken word without falling apart at either end. The in-line control handles calls through the built-in microphone and skips tracks forward and back, which is the kind of thing you notice on a commute or during a work call, not in a spec list.
The feature that actually sets it apart is the sharing jack. A second headphone plug goes straight into the A10, so two people can listen to the same phone, tablet or laptop with no splitter and no extra cable. For a parent and kid on a flight, or two friends on a long train ride, that's a genuinely useful piece of design that most wired headphones at this level don't bother with.
Comfort-wise, the A10 leans on ultra-soft ear cushions, a padded headband and an adjustable slider. The frame is plastic and it weighs 0.24 kg, so it's not featherweight, but the padding is doing the work for longer sessions. It's a 3.5 mm wired headphone aimed at phones, computers, laptops, MP3/MP4 players and any other device with a standard audio jack.
IYGR K6C: Who It's For
The K6C is built around one idea: protect small ears and fit small heads. The 84dB volume-limiting technology is the headline, and it's the reason this pair exists — it holds the output down so educational apps, audiobooks, videos and games stay at a level parents can live with. That single design choice is what separates it from a general-purpose headphone.
The fit story is just as deliberate. The headband has 5 size settings, and the earcups move both vertically and horizontally to match different head shapes. That's aimed squarely at ages 2–12 — toddlers, preschoolers, kindergarteners, kids up to 12 — because a headphone that doesn't actually sit right on a small head is a headphone that gets taken off in ten minutes. At 113 g (4 oz), it's noticeably light, and the lighter the pair, the less pressure on a young head over a long car ride, flight or school day.
The 40 mm dynamic driver with 32 ohm impedance and 85 dB sensitivity is a sensible match for tablets, iPads and school devices. The catch is the connector: it's USB-C, wired only. That's fine for modern tablets and laptops, but it won't go into a 3.5 mm jack, so check what your child's device actually has before you commit.
Who should skip it? Anyone who needs a standard headphone plug, or an adult who wants to share audio with a second listener — the K6C doesn't do either.
Side-by-Side: Which Should You Choose?
• Best for hearing protection → IYGR K6C. The 84dB limit is the whole point of the design.
• Best for sharing audio with a second person → JOMILIN A10. The sharing jack lets another pair plug straight in.
• Best for teens and adults → JOMILIN A10. Full 20 Hz – 20,000 Hz range, in-line mic and media control built for calls and music.
• Best for standard 3.5 mm devices → JOMILIN A10. MP3/MP4 players, older laptops, anything with a regular audio jack.
• Best for USB-C tablets and school devices → IYGR K6C. USB-C is the only connection it offers.
• Best for long-wear comfort on a small head → IYGR K6C. Lighter body plus softer, more adjustable fit.
• Best for a mixed-age household with one shared device → JOMILIN A10. The sharing jack makes it the more flexible single purchase.
In my opinion, most buyers should start with the JOMILIN A10 — the sharing jack, the in-line mic and the full-range 40 mm driver make it the more versatile wired on-ear headphone, and it works with the 3.5 mm jack almost everything still has. But if the person wearing these is a young child, I'd go the other way and pick the IYGR K6C: the 84dB limit and the 113 g adjustable build are exactly what a kid ages 2–12 needs, and no amount of extra features makes up for a headphone that isn't built for small ears. Buy the A10 for the household, the K6C for the kid.
are on ear headphones good
On-ear headphones rest against the ear rather than around it, so they tend to be lighter and more compact than over-ear models — both picks here fold and travel well. The trade-off is less isolation, since the pads don't seal around your ear the way over-ear cups do. For kids and commuters who want something light and packable, on-ear is a solid choice.
what are the best open ear headphones
Neither the JOMILIN A10 nor the IYGR K6C is an open-ear design — both are closed on-ear headphones that sit on the ear. Open-ear models leave the ear canal uncovered entirely, which is a different category. If you specifically want open-ear, you're shopping a different product type than either of these.
which are the best over the ear headphones
Over-ear headphones enclose the whole ear with larger cups; both products here are on-ear, not over-ear. Within on-ear, the choice comes down to purpose: the IYGR K6C is the better fit for a child ages 2–12 thanks to its 84dB limit and 113 g build, while the JOMILIN A10 suits teens and adults with its sharing jack and in-line mic.
what are the best over the ear headphones to buy
Since both of these are on-ear, the honest answer is that the right pick depends on the wearer and the device. For a young child, I'd choose the IYGR K6C for its volume limiting and USB-C connection. For a teen or adult on a 3.5 mm device, I'd choose the JOMILIN A10. Check the current price on Amazon before deciding, and confirm the connector matches your device.
