How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a safe, wired, plug-and-play headphone for a kid using a tablet or phone with a USB-C port, choose Bywulanda Upgrade USB Type; if you need long-wireless-runtime earbuds that stay locked in your ears through sweaty workouts and runs, choose CHENRUIDA Ear Buds. These two products barely compete for the same buyer — one is a child-safety listening tool, the other is adult sport gear. Below I break down what each one actually does, where each falls short, and which one I'd put my own money on depending on your situation.
• Bywulanda Upgrade USB Type — biggest strength: A hard 94dB volume ceiling plus a native USB-C plug, so a child gets hearing-capped audio with zero setup and no dongle to lose.
• Bywulanda Upgrade USB Type — biggest trade-off: It's wired, so it only works with USB-C devices, and there's no battery, no Bluetooth, and no active noise cancellation.
• CHENRUIDA Ear Buds — biggest strength: 48 hours of total playtime with a 1.5-hour case recharge, IPX6 sweat resistance, and Bluetooth 6.0 with a 15-meter range.
• CHENRUIDA Ear Buds — biggest trade-off: They're built for adults and movement, not for volume-limited child listening, and the ear-hook design is a very different fit than a simple on-ear cup.
• Who Bywulanda is for: Parents buying a first pair of school/travel headphones for a kid on a USB-C tablet or phone.
• Who CHENRUIDA is for: Adults who run, lift, or cycle and want earbuds that won't fall out or die mid-week.
The headline feature here is the 94dB safe volume limit. If you've ever watched a kid crank the volume on a tablet, you know why that matters. The Bywulanda headphone caps output at 94dB by design, which is the whole point of the product — it's a hearing-protection tool first and a headphone second. The sensitivity is also listed at 94dB, and the driver is a 40mm dynamic unit with 30 ohm impedance, so you're getting a full-size on-ear cup rather than a tiny in-ear bud. In my opinion that's the right call for kids, because on-ear cups are easier to put on and take off than inserting tips into small ears.
The second thing that stands out is the native USB-C plug. No adapter, no converter, no "where did the dongle go" panic on the way to school. It plugs straight into USB-C phones and tablets and just works. For a parent, that's a genuinely underrated feature — the fewer tiny parts in the equation, the better. The headband is adjustable and rated to fit heads from kids up to teenagers, and the whole thing folds down for travel. The enclosure is faux leather and plastic, ear placement is on-ear with an over-ear style earpiece, and the theme is aimed at movie and video-game use, which fits the tablet-and-travel story. There's also a 2-year warranty and a stated 24-hour customer support line.
Who should buy it: parents who want capped volume, a wired connection that never needs charging, and a foldable design that survives a backpack. Who should skip it: anyone who needs Bluetooth, anyone with a Lightning or 3.5mm-only device, and any adult who wants active noise cancellation — this headphone uses sound isolation, not ANC. It's also worth noting the color is Light Purple, so if that's not your kid's taste, that's a real consideration.

The CHENRUIDA M145 is unapologetically sport gear. The design brief is clear: elastic soft ear hooks plus three sizes of ear tips so the buds stay put during workouts. That combination is the difference between finishing a run with music and finishing a run fishing a bud out of your collar. The IPX6 waterproof rating handles sweat and splashes, which is exactly the abuse these will take at the gym or on the road.
Battery is the other big story. You get 8 hours per charge and 48 hours total with the case, and the case itself refills in about 1.5 hours. There's an LED display on the case showing battery status, so you're not guessing whether you have juice before a long session. Connectivity is Bluetooth 6.0 with a stated 15-meter range, which is generous enough to leave your phone on a bench or treadmill and keep moving.
Who should buy it: runners, gym-goers, cyclists, and anyone who wants wireless freedom with serious runtime. Who should skip it: young kids, anyone who wants a volume cap, and anyone who prefers the feel of an on-ear cup over an in-ear bud. The color is Silvery, and there's no wired fallback — it's Bluetooth only.
Side-by-Side: Which Should You Choose?
• Best for child hearing protection → Bywulanda Upgrade USB Type. The 94dB limit is the entire reason to buy it.
• Best for battery life → CHENRUIDA Ear Buds. 48 hours total with a 1.5-hour case recharge, versus a wired headphone that never needs charging at all but also never leaves the device.
• Best for workouts and running → CHENRUIDA Ear Buds. Ear hooks, three tip sizes, IPX6, and button controls instead of touch.
• Best for school, tablets, and travel → Bywulanda Upgrade USB Type. Native USB-C plug, foldable, adjustable headband.
• Best for connectivity range → CHENRUIDA Ear Buds. Bluetooth 6.0 with a 15-meter stated range.
• Best for noise control → CHENRUIDA Ear Buds. It lists Active Noise Cancellation; Bywulanda relies on passive sound isolation.
• Best for a no-charging, no-pairing routine → Bywulanda Upgrade USB Type. Plug in and go, no battery to manage.
• Best for adults in general → CHENRUIDA Ear Buds. The listed age range is adult, and the feature set is built around movement.
If I were buying for a child, I'd pick the Bywulanda Upgrade USB Type without much hesitation. The 94dB cap, the native USB-C plug, and the foldable on-ear build line up exactly with how kids actually use headphones — on a tablet, on a trip, in the car. If I were buying for myself to run or train, I'd pick the CHENRUIDA Ear Buds instead. Ear hooks, IPX6, 48 hours of runtime, and physical buttons are the right answers for sweaty, moving use. In my opinion these aren't really rivals; they're answers to two different questions.
Yes — that's the intended use. It's wired USB-C, foldable, and volume-limited at 94dB, so it works with USB-C tablets and phones without an adapter. Just confirm your child's device has a USB-C port, since there's no 3.5mm or Bluetooth option.
That's the total with the charging case. Per charge it's listed at 8 hours, and the case recharges in about 1.5 hours. Real-world runtime depends on volume and ANC use, but the case-plus-buds math is where the 48-hour figure comes from.
They can physically, but I wouldn't recommend it as a first choice. There's no volume cap, the age range is listed as adult, and the ear-hook fit is designed around workouts. For a child, the Bywulanda's 94dB limit is the safer pick.
Both sit in different categories, so value depends on what you need. Check the current price on Amazon for each using the buttons on this page, then compare against the features that matter to you — volume limiting and wired simplicity versus 48-hour wireless runtime and sport fit.
