How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a volume-limited pair of on-ear headphones built specifically for young kids, choose vinamass Kids Headphones; if you need Lightning earbuds with a mic and remote for an iPhone, choose IIOZO Apple MFi Certified.
• vinamass Kids Headphones — biggest strength: a fixed 85dB volume limiter plus an on-ear, bendable, lightweight build aimed squarely at children aged roughly 3–15.
• vinamass Kids Headphones — biggest trade-off: it's a wired 3.5mm headphone, so it won't plug into an iPhone that only has a Lightning port without an adapter, and it has no microphone or call controls.
• IIOZO Apple MFi Certified — biggest strength: a Lightning plug that fits modern iPhones directly, plus an inline remote and built-in microphone for calls, playback and volume.
• IIOZO Apple MFi Certified — biggest trade-off: it's designed for adults, ships as a two-pack of in-ear earbuds, and offers no volume limiting — so it isn't a child-safety product.
• Who each is for: pick vinamass for a young child who needs safe listening on a tablet, Chromebook or Switch; pick IIOZO for an iPhone owner who wants a spare set of wired earbuds for calls and music.
The vinamass A63 is a kids' headphone first and an audio product second, and that ordering is the whole point. Its headline feature is a fixed safe volume limit set to 85dB, which the brand says meets the WHO recommended limit level. That number matters because it's fixed — there's no app, no switch, no parental toggle to remember. A child can't quietly raise the volume past it, which is exactly the kind of thing that matters when a kid is using a tablet unsupervised in the back seat or at a desk.
The physical design backs that up. It's an on-ear model in red, built from a flexible, bendable carbon-fiber-style plastic headband that the brand says is hard to break, with soft silicone and foam ear cushions covered in PU leather. The headband adjusts up to about 3cm, and the brand positions the fit range from toddlers through teens, roughly ages 3 to 15. Five adjustment levels are mentioned, so it's meant to grow with a child rather than be replaced every year. The cable is nylon fabric, chosen because it resists tangling and survives a certain amount of pulling and dragging — a realistic concern with kids.
On the audio side, it's a straightforward wired headphone: 32 ohm impedance, a dynamic driver, and a 20Hz–20,000Hz frequency range, connecting through a standard 3.5mm jack. That jack is the practical key here — it works with smartphones, Chromebooks, Kindle Fire, Switch, iPad and tablets, so it covers the devices kids actually use at school and at home.
Buy it if you have a young child, you want hearing protection you don't have to supervise, and the devices in your house have a headphone jack. Skip it if the listener is an adult, if you need a microphone for calls or video classes, or if your only device is an iPhone with a Lightning port and no adapter.
The IIOZO set solves a completely different problem. These are white, in-ear wired earbuds that terminate in a Lightning connector, described as MFi certified and compatible with iPhone 14, 13, 12, 11 Pro Max, XS, XR, X and 8/7. If you've got a modern iPhone with no headphone jack, that Lightning plug is the difference between "works out of the box" and "needs a dongle."
The feature list is aimed at an adult commuter or exerciser. There's an inline remote that handles volume, playback and answering or ending calls, and a built-in microphone — so these double as a headset. The brand claims a 100% copper core for lossless digital sound and support for 48KHz/24-bit audio output, which is a spec worth knowing if you care about fidelity from a wired connection. Noise control is passive: the in-ear seal physically blocks some surrounding sound rather than cancelling it electronically, and the brand pitches this for work, study and sports.
Two practical details stand out. First, it's sold as a 2-pack, so you get a backup pair — genuinely useful given how easily wired earbuds get lost or damaged. Second, the age range is listed as Adult, and there's a 36-month warranty with 24/7 customer service attached to the product.
Buy it if you own an iPhone with a Lightning port, you take calls and want a mic and remote on the cord, and you'd rather have a spare pair on hand. Skip it if you're shopping for a child — there's no volume limiter here at all — or if your devices use a standard 3.5mm jack rather than Lightning.
Side-by-Side: Which Should You Choose?
• Best for young children → vinamass Kids Headphones. The 85dB fixed limiter and on-ear fit for ages 3–15 are the deciding factors.
• Best for iPhone users → IIOZO Apple MFi Certified. The Lightning connector removes the adapter problem entirely.
• Best for device flexibility → vinamass Kids Headphones. A 3.5mm jack works with Chromebooks, tablets, the Switch, Kindle Fire and more.
• Best for durability against rough handling → vinamass Kids Headphones. The bendable headband and nylon cable are designed around kids pulling and dragging.
• Best for having a backup → IIOZO Apple MFi Certified. It ships as a two-pack.
• Best for passive noise blocking → IIOZO Apple MFi Certified. The in-ear seal reduces surrounding sound; the vinamass relies on on-ear sound isolation.
• Best for hearing-safety peace of mind → vinamass Kids Headphones. There is simply no equivalent safeguard on the IIOZO.
In my opinion, these two don't really compete — they serve different people, and the right answer depends entirely on who's wearing them. If I were buying for a child, I'd take the vinamass Kids Headphones without hesitation: the fixed 85dB limit is the single most important feature in a kids' headphone, and the bendable headband, adjustable fit and tangle-resistant nylon cable are all built for how children actually treat their gear. If I were buying for myself and I own a Lightning iPhone, I'd take the IIOZO Apple MFi Certified instead — the remote, mic and native Lightning plug make it a better everyday headset, and the two-pack means a spare when one goes missing. Match the product to the listener, and you'll be happy either way.
how to wired headphones work
A wired headphone sends the audio signal from your device down the cable to the drivers in the earcups or earbuds, powered by the device itself rather than a battery. That's why neither of these needs charging — the vinamass uses a 3.5mm jack, and the IIOZO uses a Lightning connector.
how to use wired headphones with iphone
If your iPhone has a Lightning port, plug the IIOZO earbuds straight in — they're built for iPhone 14, 13, 12, 11 Pro Max, XS, XR, X and 8/7. If you want to use the vinamass on that same iPhone, you'd need a 3.5mm-to-Lightning adapter, since its jack is a standard 3.5mm.
how to fix wired headphones no sound
Check the obvious things first: the plug is fully seated, the volume isn't at zero, and the cable isn't kinked near the connector. Then try the headphones on a second device — if they work there, the problem is your source, not the headset. On the IIOZO, also make sure the inline remote isn't paused and the mic/call controls are functioning.
how to wired headphones (for kids specifically)
For a child, the main setup step is fit: adjust the vinamass headband — it extends up to about 3cm across five levels — so the on-ear cushions sit comfortably without pressing. Then just plug the 3.5mm jack into the tablet, Chromebook or Switch. The 85dB limit is fixed, so there's nothing else to configure.
