If you want a protective hard shell that lets Apple AirPods Max sleep while it travels, choose co2CREA Hard Case; if you need a volume-limited USB-C headphone for a kid at school or on a tablet, choose Bywulanda Upgrade USB Type.
• co2CREA Hard Case — biggest strength: a hard EVA shell with a magnetic bottom device that puts AirPods Max into their dormant state, so the case doubles as protection and sleep mode.
• co2CREA Hard Case — biggest trade-off: it is a case only. No headphones, no charger, no accessories are included, and it fits just the AirPods Max.
• Bywulanda Upgrade USB Type — biggest strength: a 94dB safe volume limit plus a wired USB-C connection, which is exactly what parents want for young ears and school devices.
• Bywulanda Upgrade USB Type — biggest trade-off: it is wired and on-ear, so there is no wireless freedom and isolation is passive sound isolation only.
• Who each pick is for: co2CREA for AirPods Max owners who carry their headphones around; Bywulanda for kids, students and tablet users who need a safe, simple wired headphone.
The co2CREA Hard Case is a purpose-built shell for the Apple AirPods Max. It is made from ethylene vinyl acetate — a hard EVA shell, in plain terms — and the brand lists it as shockproof, dustproof and water resistant. That combination is what you want when a pair of over-ear headphones lives in a backpack, a carry-on or a car. The soft anti-static lining is there to keep the AirPods Max from picking up bumps, dents and scratches, and the strong zipper is meant to hold up to repeated opening and closing.
What makes this case different from a generic pouch is the magnetic device on the bottom. AirPods Max enter their dormant state when the magnets in the original Smart Case engage, and co2CREA built that same magnetic function into the base of this case. So instead of pulling your headphones out and hunting for the Smart Case, you can drop them straight into the co2CREA shell and let them sleep. The design also leaves room for chargers and other accessories, and the AirPods Max can sit in the case either alone or still inside the Smart Case.
In my opinion, this is the case to buy if you own AirPods Max and you actually take them places — commuting, flights, the gym bag, a desk drawer at the office. The comfortable hand strap is a small thing, but it matters when you are carrying the case on its own rather than stuffing it into a bag. The dimensions — roughly 9.21 by 8.98 by 2.4 inches — tell you it is a compact, flat-ish travel bag rather than a bulky hard box.
Skip it if you do not own AirPods Max, because nothing else fits. Skip it too if you expect headphones, a cable or a charger in the box. The listing is explicit: for sale is the case only. It also ships in Emerald Green, so if you want a neutral black accessory, this is not that.
The Bywulanda Upgrade USB Type is a kids' headphone built around one core promise: a 94dB safe volume limit. That number is the whole point. For parents, a hard ceiling on loudness is the feature that turns a cheap pair of headphones into a responsible purchase, because young ears are more vulnerable to sustained loud audio. The brand frames it as hearing protection with peace of mind, and the design backs that up with a volume control on the headset itself.
It is a wired USB-C headphone — Type C connectivity, no wireless technology, no battery to charge. That sounds like a limitation, and for an adult it would be. For a kid with a school tablet or a Chromebook, it is a feature: nothing to pair, nothing to run out of, nothing to lose connection mid-lesson. The 30 ohm impedance and dynamic driver are ordinary, sensible specs for an on-ear headphone meant for streaming video and classroom audio. Sound isolation is passive, so it takes the edge off a noisy room without any active electronics.
Weight is listed at 0.18 kg, which is light enough for a child to wear for a school day, and the foldable, on-ear design is aimed squarely at boys, girls and students. The navy blue plastic build reads as durable everyday gear rather than a premium audio product, and the volume control is a button-style control. Bywulanda also lists a 2-year warranty and 24-hour customer support, which is a longer coverage window than the 1-year warranty on the co2CREA case.
Buy this if you have a kid with a USB-C tablet, a school laptop or a travel bag that needs a spare headphone. It is also a reasonable gift for a birthday or holiday, since the themes listed — movie and video game — match how kids actually use headphones. Skip it if you want wireless audio, if you need a 3.5mm plug, or if you are buying for an adult who wants full-size sound. This is a children's product through and through, and it is honest about that.
Side-by-Side: Which Should You Choose?
• Best for sleep mode on the go → co2CREA Hard Case. The magnetic device in the bottom lets AirPods Max enter their dormant state without the original Smart Case.
• Best for hearing safety → Bywulanda Upgrade USB Type. The 94dB volume limit is the headline feature and the reason most parents look at it.
• Best for school and tablet use → Bywulanda Upgrade USB Type. Wired USB-C means no pairing, no charging and no dropped connection during class.
• Best for travel with accessories → co2CREA Hard Case. It has room for chargers and extras, plus a hand strap for carrying it on its own.
• Best for a lightweight fit on a child → Bywulanda Upgrade USB Type. At 0.18 kg with a foldable on-ear design, it is built for small heads and small bags.
• Best warranty coverage → Bywulanda Upgrade USB Type. Two years versus one on the co2CREA case.
• Best for adults → co2CREA Hard Case. Not as audio gear, but as the accessory an adult AirPods Max owner actually needs.
These two products do not compete for the same buyer, so my recommendation splits cleanly. If I owned Apple AirPods Max and carried them anywhere, I would buy the co2CREA Hard Case — the magnetic sleep function and hard EVA shell solve a real problem, and the Emerald Green finish gives it some personality. If I were buying for a child with a school tablet, I would buy the Bywulanda Upgrade USB Type — the 94dB limit is the feature that matters most, and the wired USB-C design is simpler for a kid to live with. Check the current price on Amazon before you commit, since both are the kind of purchase where the value call is yours.
FAQ
Yes, in my opinion. The AirPods Max can sit in the co2CREA case either alone or still inside the Smart Case, and the case's own magnetic bottom means it can trigger sleep mode by itself. You get hard-shell protection the fabric Smart Case does not provide.
It is a wired USB-C headphone, so it works with anything that has a USB-C port and supports audio over USB-C — tablets, laptops and many phones. It has no wireless mode and no 3.5mm jack, so check your device's port first.
The Bywulanda Upgrade USB Type, clearly. The 94dB safe volume limit, light 0.18 kg build and on-ear fit are all designed for kids. The co2CREA Hard Case is not a headphone at all — it is storage for AirPods Max.
Not directly. One is a hard travel case for Apple AirPods Max; the other is a volume-limited USB-C kids' headphone. The right choice depends entirely on whether you need to protect headphones you already own or buy headphones for a child.
