• Bywulanda USB-C Kids Headphones — biggest strength: a complete, school-ready wired headphone with a USB-C jack, a mic, an adjustable headband, a foldable frame and switchable 85/94dB volume limiting.
• Bywulanda USB-C Kids Headphones — biggest trade-off: it is wired only. There is no Bluetooth, so your child is tethered to the tablet, laptop or phone by the cable.
• Perfcaze Headphone Case — biggest strength: a hard EVA shell with a water-resistant PU outer skin, a mesh pocket for a cable and a carry strap, sized for specific foldable over-ear models.
• Perfcaze Headphone Case — biggest trade-off: it is a case only. No headphones are included, and it is built around a short compatibility list, so it is not a universal fit.
• Who each pick is for: buy the Bywulanda if a child needs headphones for school, travel or a tablet; buy the Perfcaze if you already own compatible foldable over-ear headphones and want to stop them getting crushed.
The Bywulanda USB-C Kids Headphones are built around one idea: a child should be able to plug in and listen without you worrying about the volume. The headline feature is the two-stage safe volume limit at 85dB and 94dB. The lower setting is the one I would leave on for younger kids and long listening sessions; the higher one gives a bit more headroom for noisy environments like a car or a plane cabin. That switch is the single most useful thing on this product for a parent.
The rest of the design is sensibly practical. The connection is USB-C rather than the old 3.5mm plug, which matters if your household has moved to modern iPads, tablets, laptops and phones that no longer have a headphone jack. There is a built-in mic, so it works for class calls and video lessons, not just music. The headband is adjustable, the ear cups are over-ear with a faux leather and plastic build, and the whole thing is foldable — which is the detail that ties these two products together. Folding the ear cups flat and tucking the headband in makes a meaningful difference in a backpack that is already full of books.
On the technical side, the drivers are dynamic, impedance is 32 ohm, and the frequency range is 20Hz to 20,000Hz — a standard full-range spec that tells you it will handle speech, music and video without obvious gaps. Controls are a button-based volume control with sound isolation rather than active noise cancellation. It weighs 5 ounces, which is light enough for a child to wear through a school day. It ships as one unit with a user manual and carries a 2-year warranty description, which is a reassuring signal for something a kid will treat roughly.
Buy it if you want a wired, volume-limited, folding headphone for a kid or young teen using USB-C devices at school, at home or on trips. Skip it if you need wireless freedom, active noise cancellation, or a headphone for an adult who wants a more premium sound signature.
The Perfcaze Headphone Case is the opposite kind of purchase: it is not about sound at all, it is about survival. This is a hard shell EVA case with a PU skin outer, and the combination is the point. EVA gives you a shockproof, pressureproof structure, so a headphone sitting in a backpack does not get crushed by a laptop or a water bottle. The PU outer is water resistant, dustproof and fingerprint resistant, and the practical upshot is that when it gets grubby you just wipe it down rather than scrubbing fabric.
The design details are aimed at daily carrying. There is a mesh pocket inside for a cable, which is exactly where loose USB-C or audio cables should live so they do not scratch the ear cups. The zipper is described as smooth and easy to open and close — a small thing until you are doing it one-handed in a hurry. There is a portable carrying strap, so you can carry it by hand, hang it on a wall hook, or drop it in a bag. And there is a headphone logo on the case to match the headphones.
The important caveat is compatibility. This is not a universal case. It is made for BERIBES WH202A and WH305B, Skullcandy Crusher Evo and Crusher ANC 2, and TOZO models — and, per the product description, the case is colour-matched to those headphones. It is built for foldable over-ear headphones, which is why the interior dimensions work: a folding headphone collapses into a much more compact shape, and that is the shape this case is designed around. If your headphones do not fold, or are not on that list, this is the wrong case for you. There is also no warranty described, so you are relying on the build quality itself. And to be blunt about the obvious: there are no headphones in the box.
Buy it if you own compatible foldable over-ear headphones and want hard-shell protection for commuting, school or travel. Skip it if you need headphones, or if your model is not on the compatibility list.
Side-by-Side: Which Should You Choose?
• Best for protecting headphones you already own → Perfcaze Headphone Case, with its hard EVA shell and shockproof, pressureproof construction.
• Best for USB-C devices → Bywulanda USB-C Kids Headphones. The USB-C jack is the whole point of the model name.
• Best for travel and commuting → it depends on the job — Bywulanda for the listening, Perfcaze for the carrying, and the two actually work well as a pair.
• Best for packing in a tight bag → Bywulanda USB-C Kids Headphones fold down, and the Perfcaze case is designed specifically around foldable over-ear headphones.
• Best for keeping cables tidy → Perfcaze Headphone Case, which has a dedicated mesh pocket for a cable.
• Best for long-term peace of mind → Bywulanda USB-C Kids Headphones, since it carries a 2-year warranty description, while the case lists none.
• Best for someone who wants zero setup → Bywulanda USB-C Kids Headphones. Plug in, set the volume limit, done. No pairing, no charging.
If I had to pick one, I would buy the Bywulanda USB-C Kids Headphones. It is the product that actually does something — it delivers sound, limits volume, folds for storage and works with the USB-C devices most families already own. In my opinion, a case is a smart accessory but not the thing you set out to buy. That said, if you already own one of the compatible foldable over-ear models, the Perfcaze case is a genuinely sensible add-on, and pairing the two covers both the listening and the protection. Check the current price on Amazon before you decide, since that is the one variable I cannot speak to here.
Foldable headphones are over-ear headphones whose ear cups and headband hinge so the whole thing collapses into a smaller, flatter shape for storage and travel. Both products here relate to that design: the Bywulanda headphones fold down themselves, and the Perfcaze case is built specifically to hold foldable over-ear headphones.
How to fold foldable headphones?
On most folding models you rotate each ear cup so it lies flat against the headband, then fold the headband in on itself. The exact motion varies by model, so follow the manufacturer's instructions. The practical payoff is that a folded headphone fits the compact interior of a case like the Perfcaze.
If your headphones do not have visible hinges, do not force them — you will damage the headband. Some models simply are not foldable, which also means a foldable-specific case may not be the right fit. In that situation, check the compatibility list on the Perfcaze case before buying.
Fixes depend entirely on what broke, so there is no single answer. A common weak point is the hinge or the cable near the jack, and a wired model like the Bywulanda depends on that USB-C connection working. For anything structural, contact the manufacturer — the Bywulanda carries a 2-year warranty description, while the Perfcaze case lists no warranty.
