How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired USB-C kids' headphone with a hard 94dB volume ceiling for school and tablet use, choose Bywulanda Upgrade USB Type; if you need a rugged EVA hard-shell travel case built specifically to store and protect Apple AirPods Max or AirPods Max 2, choose khanka Case.
• Bywulanda Upgrade USB Type — biggest strength: A 94dB safe-volume limit plus wired USB-C connectivity, so there is no battery to charge and no way for a child to push the volume past a hearing-safe ceiling.
• Bywulanda Upgrade USB Type — biggest trade-off: It is wired and USB-C only, so it will not work with older 3.5mm jacks, Lightning devices, or anything without a Type-C port, and it is a plastic on-ear build rather than a premium one.
• khanka Case — biggest strength: A hard EVA shell with a soft velvet lining and an anti-static interior, plus a dual-compartment layout (mesh pocket up top, headphone cradle below) for cables and adapters.
• khanka Case — biggest trade-off: It is a case only — no headphones included — and it is shaped specifically for Apple AirPods Max / Max 2, so it is not a generic fit for other headphones.
• Who each is for: Bywulanda is for a parent buying a first "school" headphone for a kid; khanka is for someone who already owns AirPods Max and wants to carry them safely.
The Bywulanda Upgrade USB Type C Kids Headphone is, at its core, a safety-first design. The headline spec is the 94dB volume limit. For a parent, that number matters more than any other line on the sheet: it means the headphone's output is capped at a level generally treated as safe for young ears over longer listening sessions. You are not relying on your child to self-regulate the volume slider, and you are not relying on a parental app. The ceiling is built into the hardware.
The second thing to understand is the connection. This is a wired, USB-C headphone — the jack is Type C and the wireless technology field is listed as USB-C, which really just confirms the wired digital connection. That has two practical consequences. First, no battery: nothing to charge, nothing to die mid-lesson, no "my headphones are dead" five minutes before the school bus. Second, it will only work with devices that have a USB-C port — modern tablets, many newer laptops, and USB-C phones. If your household still runs on 3.5mm headphone jacks or Lightning, this is the wrong pick, plain and simple.
On comfort and build, the sheet describes an on-ear fit with an over-ear earpiece shape, a plastic enclosure in navy blue, and a foldable, lightweight body at 0.18 kg. That weight is genuinely light for a kids' headphone, and the folding design matters more than people expect — it is the difference between a headphone that disappears into a backpack pocket and one that gets crushed. The 30 ohm impedance and dynamic driver suggest an easy-to-drive headphone that does not need a powerful source, which is exactly what you want when it is plugged straight into a tablet. There is a button-based volume control on the ear cup, sound isolation rather than active noise cancellation, and the theme is pitched at movies and video games. A 2-year warranty is listed.
I recommend it for: parents of younger students who want a hearing-safe, charge-free headphone for school, tablets, and travel. Skip it if: your devices use 3.5mm or Lightning, or if you need wireless freedom or active noise cancellation.
The khanka Case flips the whole equation: it is not audio gear at all. It is a protective travel case built for the Apple AirPods Max and AirPods Max 2, and the compatibility line is the most important thing on the sheet. If you do not own AirPods Max, this product is not for you — the interior is molded around that specific headphone.
What you get is a hard EVA shell with a nylon exterior, in orange. EVA is the same family of material used in a lot of crush-resistant cases, and khanka's pitch is straightforward: it absorbs the knocks of outdoor travel, keeps dust off the headphones, and shrugs off water splashes so the interior stays dry. Inside, the story is the lining — a soft velvet surface that cushions collisions and resists dents and scratches, plus an anti-static material that is meant to prevent electrostatic damage to the headphones. That is a detail worth noting because static discharge is a real (if uncommon) failure mode for electronics, and most cheap cases do nothing about it.
The organization is dual-compartment. Under the lid there is a secure mesh pocket for cables and adapters; the lower section cradles the headphones themselves. khanka explicitly says this works whether or not you use the Apple Smart Case, which is a sensible bit of flexibility. Carrying is handled by a comfortable hand strap, and the zipper is described as smooth and durable, not prone to sticking — a small thing until you are standing at a gate trying to open a jammed case one-handed. Additional features listed include dust resistance, heavy-duty protection, shockproofing, and a lightweight, travel-ready shell. A 1-year warranty is listed.
I recommend it for: AirPods Max owners who travel, commute, or just want the headphones stored somewhere safer than a bag pocket. Skip it if: you own any other headphone brand, or if you were hoping the listing included the headphones — it does not. Only the case is in the box.
Side-by-Side: Which Should You Choose?
• Best for protecting a child's hearing → Bywulanda Upgrade USB Type. The 94dB hardware limit is the entire point of the product.
• Best for zero-charge convenience → Bywulanda Upgrade USB Type. Wired USB-C means no battery to manage, ever.
• Best for travel durability → khanka Case. Hard EVA shell, shockproofing, water-splash resistance, and a velvet-lined interior.
• Best for older devices → neither, honestly. Bywulanda needs USB-C; khanka needs AirPods Max. Check your gear first.
• Best for cable and adapter organization → khanka Case. The mesh pocket under the lid is made for exactly that.
• Best for a lightweight, foldable daily carry → Bywulanda Upgrade USB Type. At 0.18 kg with a folding body, it is built to be tossed in a backpack.
• Best for a gift → Bywulanda Upgrade USB Type. It is positioned as a kids' gift for birthdays and holidays; the case is a practical add-on for someone who already owns the headphones.
These two products are not really competitors — one is a headphone, the other is a case for a completely different brand's headphone. So my recommendation depends entirely on what you actually need. If you are shopping for a child, I would buy the Bywulanda Upgrade USB Type. The 94dB limit, the charge-free wired USB-C connection, and the light foldable build solve the three problems parents actually have. If you already own AirPods Max, I would buy the khanka Case — the EVA shell and velvet lining are a real step up from stuffing premium headphones in a bag. Just confirm your device ports and your headphone model before ordering, because neither product bends to fit the wrong setup.
FAQ
No. The listing states that only the case is available for purchase and that the headphones and accessories shown are not included. You need to already own AirPods Max or AirPods Max 2.
Only if the device has a USB-C port. It will not work with Lightning connectors or standard 3.5mm headphone jacks, so check your device before buying.
