If you want a wired, volume-limited kids' headphone for school and tablet use, choose Bywulanda Upgrade USB Type; if you need wireless open-ear earbuds for running, cycling and calls, choose RICHJOY Open Ear Earbuds. They are not really competitors — they solve two completely different problems, and the "better" one is simply the one that matches how you'll actually use it.
• Bywulanda Upgrade USB Type — biggest strength: a hard 94dB volume limit plus a USB-C plug that needs no adapter, built specifically for kids' ears and school devices.
• Bywulanda Upgrade USB Type — biggest trade-off: it's wired and Type-C only, so it won't work with a 3.5mm jack or any older device without the right port.
• RICHJOY Open Ear Earbuds — biggest strength: up to 40 hours of total playtime with a charging case that shows real-time battery, plus an open-ear clip design that stays put during workouts.
• RICHJOY Open Ear Earbuds — biggest trade-off: open-ear earbuds trade some isolation for comfort, so noisy environments can bleed into what you hear.
• Choose Bywulanda if you're buying for a child who needs safe listening on a tablet, phone or school laptop with a USB-C port.
• Choose RICHJOY if you're an adult who wants wireless earbuds for fitness, driving, running or commuting.
The Bywulanda Upgrade USB Type is a kids' on-ear headphone with one job it takes seriously: protecting young ears. The headline feature is the 94dB safe volume limit, which caps how loud the headphones can get. For a parent, that's the whole point — you don't have to hover over a child's tablet checking the volume slider every few minutes. The cap does the worrying for you.
The design backs that up in practical ways. It's wired over USB-C, so there's no pairing, no charging, no "the earbuds died halfway through the movie" moment. Plug it into a USB-C phone, tablet or laptop and it plays — no adapter required, which matters because a lot of modern devices have dropped the old headphone jack entirely. Inside, 40mm dynamic drivers cover a 20Hz–20,000Hz range with 30 ohm impedance, which is a sensible, easy-to-drive setup for cartoons, music and games rather than critical listening.
Then there's the fit and the travel factor. The headband adjusts to fit heads from young kids up through teenagers, the on-ear cushions are described as soft for longer sessions, and the whole thing folds down to take up less room in a bag. At 0.18 kg it's light enough that a child won't fight it. The mint green finish is a small thing, but kids care about that stuff.
Who should skip it: anyone whose device only has a 3.5mm jack, anyone who wants wireless freedom, and any adult looking for serious audio gear. This is a purpose-built kids' product, and it's honest about that.
RICHJOY Open Ear Earbuds: Who It's For
The RICHJOY Open Ear Earbuds go after a totally different buyer: someone who wants sound in their ears without anything stuffed inside them. The C-shaped clip design hooks over the ear rather than sealing into the canal, and at just 4.8 grams per earbud, the idea is that you forget you're wearing them. The brand specifically calls out long workouts, running, cycling, driving and working from home — situations where in-ear pressure gets annoying fast.
Battery is the other big story. RICHJOY rates these at up to 40 hours of total playtime with the charging case, and the case has a built-in screen showing real-time battery levels. That's a genuinely useful detail: instead of guessing whether you have juice for a long ride, you glance at the case. For commuters, gym-goers and travelers, that removes a low-level anxiety that plagues a lot of small earbuds.
On the audio and call side, the earbuds use directional audio to push sound toward the ear canal while limiting leakage, and they run Bluetooth 6.0 for wireless pairing with iPhone, Android, iPad, PC and more. The ENC (Environmental Noise Cancellation) microphone is aimed at calls — it's designed to reduce wind and background noise so you sound clearer on meetings and phone calls. With IPX5 water resistance, sweat, rain and splashes are handled, which lines up with the fitness positioning.
Who should buy it: runners, cyclists, gym regulars, drivers and anyone who takes a lot of calls on the move. If you find normal earbuds uncomfortable after an hour, the open-ear approach is worth considering. The 1-year manufacturer warranty is a reasonable baseline.
Who should skip it: if you want deep isolation on a plane or a noisy train, open-ear designs let the world in by nature. And if you're shopping for a young child, this isn't the product — it's wireless, has no volume cap, and is aimed at adults.

If I were buying for myself, I'd take the RICHJOY Open Ear Earbuds — the wireless freedom, 40-hour playtime and the battery display on the case make them the more versatile everyday companion for fitness and calls. But this isn't a fair fight, because the Bywulanda Upgrade USB Type isn't trying to compete with them. If I were buying for a child, I'd choose Bywulanda without hesitation: the 94dB limit, wired simplicity and adjustable foldable fit are exactly what a parent wants. Pick by the person, not by the spec sheet.
Not directly. Bywulanda is a wired, volume-limited kids' on-ear headphone; RICHJOY is a wireless open-ear earbud for adults. Compare them only as two answers to "what should I buy for this specific person?"
They sit in different product categories, so pricing varies over time. I don't quote prices here because they change — use the current price check on Amazon to compare them for yourself before deciding.
The Bywulanda Upgrade USB Type, in my opinion. The 94dB volume limit, USB-C plug-and-play and kid-sized adjustable headband are all designed around children. The RICHJOY earbuds are wireless, uncapped and aimed at adult fitness use.
Yes. RICHJOY's ENC microphone targets clear calls in noisy spots, and Bywulanda's 40mm drivers and USB-C connection work fine for tablet gaming and video.
