If you want a kids' on-ear headphone that works with almost any device you already own and is built to survive being folded into a backpack on the way to the library, choose JLab JBuddies Studio 2; if you need a USB-C plug that goes straight into a modern tablet or phone with no adapter and a slightly higher safe-volume ceiling, choose Bywulanda Upgrade USB Type.
• JLab JBuddies Studio 2 — biggest strength: a 3.5 mm wired jack plus braided-nylon tangle-free cord, so it works with the widest range of devices, from old library desktops to handheld players.
• JLab JBuddies Studio 2 — biggest trade-off: the 85 dB volume limit is lower than the Bywulanda's 94 dB, which some older kids will notice as "quieter."
• Bywulanda Upgrade USB Type — biggest strength: native USB-C plug with no converter needed, plus 40 mm dynamic drivers and a 94 dB safe-volume limit.
• Bywulanda Upgrade USB Type — biggest trade-off: it only fits USB-C jacks, so a device with a plain 3.5 mm headphone port is out of luck.
• Pick the JLab if your kid bounces between multiple devices, needs maximum hearing protection, and you want a lifespan warranty.
• Pick the Bywulanda if your kid's tablet or phone is USB-C only and you want a single cable with no dongle to lose.
The JBuddies Studio 2 is a wired, on-ear kids' headphone built around one idea: keep it simple and keep it safe. It uses a 3.5 mm jack, so it plugs into basically everything — a school Chromebook, an old library desktop, a portable music player, a handheld game system. There's no pairing, no charging, no "why won't it connect" meltdown in the middle of a quiet study session. For a library setting, that reliability matters more than almost anything else.
Comfort is where the on-ear design earns its keep. JLab uses Cloud Foam cushions and a Cloud Foam headband, and the circular ear cups rotate 80 degrees while the whole thing folds up small enough to sit in the palm of a hand. For a kid who has to carry their own bag to the library and back, that foldability is a real quality-of-life feature, not a spec-sheet filler. The adjustable pinch-free hinges are pitched at ages 6–16, so it can grow with a child instead of being replaced every year.
The volume regulator caps output at 85 dB. In my opinion that's the right call for younger kids and for long study sessions where you don't want them slowly creeping the dial up. The trade-off is real, though: 85 dB is noticeably quieter than 94 dB, and a teenager listening to quiet classical recordings or soft-spoken audiobooks in a library might wish for a bit more headroom. The frequency range is listed at 20 Hz–20 kHz, which is a full-range spec, so it isn't inherently bass-shy — it's just capped on how loud it can go.
Who should buy it? Parents of kids roughly 6–12 who want one pair that works everywhere, folds flat, and protects young ears aggressively. Who should skip it? Anyone whose child only owns USB-C devices and would need an adapter, and older teens who want more volume. The braided-nylon cord with an in-line remote and mic is a nice touch for library use — a kid can pause a track or take a quick call without fumbling for the device.
The Bywulanda Upgrade USB Type is the more modern connector play. It's a wired on-ear headphone with a native USB-C plug — no converter, no dongle to lose in a backpack pocket. The company explicitly frames this as plug-and-play with Type-C smartphones and tablets, and that's the core selling point. If your kid's school tablet is USB-C only, this removes a whole class of "it doesn't plug in" problems.
Audio hardware is a step up on paper: 40 mm dynamic drivers, 30 ohm impedance, 94 dB sensitivity. Bigger drivers generally mean fuller sound with more low-end presence, which is why I'd point anyone hunting for the best deep bass clip on earbuds-style thump toward this one of the two — though note this is an on-ear headphone, not a clip-on, so it's the fuller low-end of the pair rather than a clip-on form factor. The 94 dB safe-volume limit is higher than JLab's 85 dB, which means more usable loudness for older kids while still being capped for hearing protection.
The design is foldable and compact for travel, and the adjustable headband expands to fit kids through teenagers. It's listed as on-ear placement with an over-ear earpiece shape, faux leather and plastic, in light purple, with a movie/video-game theme — so it's clearly aimed at the tablet-and-screen-time crowd. Controls are volume buttons plus touch control, and it lists sound isolation as a noise-control feature, which helps in a busy library or a noisy car.
The service angle is worth mentioning because it's unusual for this category: Bywulanda advertises 24-hour customer support and a 2-year warranty. That's a concrete, checkable commitment.
Side-by-Side: Which Should You Choose?
• Best for device compatibility → JLab JBuddies Studio 2. The 3.5 mm jack works with the widest range of devices, including older library computers.
• Best for USB-C tablets and phones → Bywulanda Upgrade USB Type. Native Type-C plug, no converter needed.
• Best for the lowest safe-volume ceiling → JLab JBuddies Studio 2. 85 dB versus 94 dB — the more protective limit for younger ears.
• Best for more volume headroom for older kids → Bywulanda Upgrade USB Type. The 94 dB limit gives teens more usable loudness.
• Best for bigger drivers and fuller low-end → Bywulanda Upgrade USB Type. 40 mm dynamic drivers versus JLab's full-range 20 Hz–20 kHz tuning.
• Best for folding small and traveling light → JLab JBuddies Studio 2. Cups rotate 80 degrees and fold to palm size; Bywulanda is also foldable but JLab's fold is more compact.
• Best for a low-maintenance, no-charging library setup → JLab JBuddies Studio 2. No battery, no pairing, just plug in.
• Best for warranty and support confidence → split. JLab offers a limited lifetime warranty; Bywulanda offers a 2-year warranty with 24-hour support.
If I were buying for a kid heading to the library with a mix of devices — a school laptop, a tablet, a hand-me-down player — I'd buy the JLab JBuddies Studio 2. The 3.5 mm jack is the deciding factor: it just works everywhere, the 85 dB cap is the more protective choice, and the fold-flat design is built for a backpack. For library use specifically, no charging and no pairing is a genuine advantage. I'd only switch to the Bywulanda Upgrade USB Type if the kid's tablet or phone is USB-C only and I want that plug-and-play simplicity with a bit more volume and bigger drivers.

FAQ
Not inherently — it depends on your devices. The Bywulanda Upgrade USB Type plugs directly into USB-C tablets and phones with no converter, which is convenient. The JLab JBuddies Studio 2 uses a 3.5 mm jack that works with older library computers, MP3 players and handhelds. Pick based on the ports you actually own.
The JLab JBuddies Studio 2 has the lower volume limit at 85 dB, so it caps loudness more aggressively. The Bywulanda Upgrade USB Type caps at 94 dB, which is still a safe limit but allows more volume. For younger kids I'd lean JLab; for teens who want more loudness, Bywulanda.
Neither is marketed as a sleep-specific or voice-assistant headphone. For library use, both are wired and distraction-free, which is what matters. If you want voice-assistant features or a sleep form factor, neither of these on-ear models is the right fit.
