If you want a proven wired kids' headphone with a 3.5mm jack that plugs into almost any classroom device, choose AILIHEN I35; if you need a USB-C plug for newer phones and tablets with no adapter in the way, choose Bywulanda Upgrade USB Type.
• AILIHEN I35 biggest strength: a 3.5mm jack plus a 93dB volume limit, foldable build and inline mic — the classic school-and-travel combo.
• AILIHEN I35 biggest trade-off: no USB-C, so newer tablets and phones without a headphone jack need an adapter.
• Bywulanda Upgrade USB Type biggest strength: a native USB-C plug with a 94dB limit and 40mm dynamic drivers — no converter required.
• Bywulanda Upgrade USB Type biggest trade-off: USB-C only, so anything with a standard 3.5mm socket is off the table.
• Pick AILIHEN I35 if your child's main devices still have a headphone jack (Chromebooks, laptops, MP3 players).
• Pick Bywulanda Upgrade USB Type if your household has moved to USB-C phones and tablets and you want one cable that just works.
The I35 is built around one very specific job: keeping a young child's ears safe while they listen on school hardware. The 93dB volume limit is the headline here. In my opinion that's the single most important spec on a kids' headphone, because it's the one thing a parent can't easily fix after the fact. The pillow-soft headband and memory-protein ear cushions are aimed at the same problem from a different angle — kids who won't wear a headphone that pinches or slides. A headphone that gets taken off is a headphone that isn't protecting anyone.
Then there's the connection. A standard 3.5mm jack is the least glamorous spec in audio, but it's also the most compatible. The I35 is designed to plug into Chromebooks, laptops, desktops, tablets, MP3 and MP4 players — in other words, exactly the pile of devices a school-age kid actually touches. The inline HD microphone on the braided cable handles hands-free calls and one-button music and call control, which matters for remote classes and video calls. It folds up for travel, adjusts to fit different head sizes, and the whole thing weighs 5.92 ounces, light enough for a child aged 3 and up to wear without complaining.
Bywulanda Upgrade USB Type: Who It's For
The Bywulanda takes the opposite bet. Instead of maximum compatibility, it goes for a clean, modern connection: a native USB-C plug with no converter needed. Plug it into a USB-C phone or tablet and it just works. For a lot of families in 2024 and beyond, that's the whole ballgame — the tablet in the house is USB-C, the phone is USB-C, and there's no dongle to lose in a school bag.
Its volume limit sits at 94dB, essentially the same protection philosophy as the AILIHEN, just a notch higher on paper. The audio side is where the two products genuinely diverge: the Bywulanda uses 40mm dynamic drivers, which is a notably larger driver than you'd typically expect in this category, and the brand positions it as "HD stereo sound." I'd frame that as a design choice aimed at slightly older kids and students who care more about how movies and games sound. The theme tags — movie and video game — back that up. This reads like a headphone for a kid who has graduated from "toddler proof" to "actually wants decent sound."
On comfort and fit, it's the same playbook: foldable for travel, adjustable headband that stretches from kids to teenagers, faux leather and plastic build, soft enough for long sessions. Impedance is 30 ohm, marginally easier to drive than the AILIHEN's 32 ohm, though on a wired connection that difference is academic. The controls are worth noting: volume control via a button, with sound isolation as the noise-control approach — meaning it passively blocks outside noise rather than actively cancelling it. It also carries a 2-year warranty description and the brand advertises 24-hour customer support.
Who should buy it: families on USB-C devices, students in the tween-to-teen range, and anyone who wants a slightly bigger driver for movies and games. Who should skip it: anyone whose main device is a school Chromebook or an older laptop with only a 3.5mm socket — this headphone simply won't plug in.
• Best for maximum device compatibility → AILIHEN I35 (3.5mm works on Chromebooks, laptops, MP3/MP4 and more).
• Best for USB-C phones and tablets → Bywulanda Upgrade USB Type (native Type-C, no adapter).
• Best for the youngest kids (3+) → AILIHEN I35 (explicitly designed for ages 3 and up, 5.92 oz).
• Best for older kids, tweens and teens → Bywulanda Upgrade USB Type (headband adjusts up to teen sizes, movie/game theme).
• Best for pure sound ambition → Bywulanda Upgrade USB Type (40mm dynamic drivers, HD stereo positioning).
• Best for hands-free calls and remote class → AILIHEN I35 (inline HD mic with one-button call and music control).
• Safest volume ceiling on paper → AILIHEN I35 (93dB versus the Bywulanda's 94dB — a small but real difference).
• Best for travel and packing → both fold, but I'd give the edge to whichever matches your device — folding is table stakes here.
If I were buying for my own household, I'd pick based on the port, not the spec sheet — that's the decision that actually bites you six months in. For a younger child on a school Chromebook or laptop, I'd buy the AILIHEN I35: the 3.5mm jack, 93dB limit, inline mic and 3-and-up sizing line up perfectly with how schools actually work. If your kid is older and lives on a USB-C tablet or phone, I'd buy the Bywulanda Upgrade USB Type: the native USB-C plug, 40mm drivers and teen-friendly adjustable headband make it the better long-term fit. In my opinion neither is "better" in the abstract — one is built for the headphone jack era, the other for the USB-C one.
Check the port on your child's main device first. A 3.5mm socket points you to the AILIHEN I35; a USB-C socket points you to the Bywulanda. No adapter, no drama.
The AILIHEN I35 is limited to 93dB and the Bywulanda to 94dB. Both are designed as child-safe limits, so the difference is marginal — either is a responsible choice for young ears.
Yes. Both are foldable and adjustable, so both pack down small and fit a range of head sizes. The Bywulanda's headband is described as stretching from kids through teenagers; the AILIHEN is aimed at ages 3 and up.
The Bywulanda Upgrade USB Type, in my opinion. Its 40mm dynamic drivers and movie/video-game positioning suggest it's tuned for entertainment, while the AILIHEN I35 is built around classroom listening, calls and volume safety.
