How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a complete, kid-ready wireless headphone you can hand over on a long trip, choose iClever BTH22; if you need a hard shell to protect a pair of foldable on-ear headphones you already own, choose Comecase Hard Headphone Case. That's the whole decision in one line. One is a device, the other is armor for a device — and mixing them up is the fastest way to buy the wrong thing. This comparison is about foldable headphones, and I'll keep coming back to that because it's the hinge the whole choice swings on. If your actual goal is the best wireless headphones for swimming, neither of these is the answer, and I'd rather tell you that up front than let you find out later.
• iClever BTH22 — biggest strength: It's the full package. Bluetooth 5.4, a 60-hour battery, a 40mm driver, Safe Volume limiting, rotating ear cups and a 10-level headband, all in a 149g over-ear body built for kids aged 2 and up.
• iClever BTH22 — biggest trade-off: It's a children's headphone first. Passive noise cancellation only, push-button controls, and a sound signature tuned around hearing safety rather than audiophile punch.
• Comecase Hard Headphone Case — biggest strength: Real protection. Hard EVA shell wrapped in PU leather, a soft fluff lining, a shockproof and water-resistant build, plus a mesh pocket, hand strap and carabiner.
• Comecase Hard Headphone Case — biggest trade-off: It makes no sound. It's the box only — no headphones inside — and it fits foldable on-ear and over-ear models up to roughly 7.5 inches.
• Who each pick is for: iClever BTH22 for the parent or gift-buyer who needs a working headphone today; Comecase for the owner of foldable headphones who wants them to survive a backpack, a locker or a carry-on.
The BTH22 is a kids' Bluetooth headphone, and almost every design choice flows from that. The headline feature is SafeSound volume limiting: iClever's Sound Refiner technology caps output below 85dBA and trims the 2K–4KHz range where sustained loud listening does the most hearing damage. Press the "+" and "–" buttons together and you drop to a 74dBA mode that's clearly aimed at toddlers. If you've ever watched a four-year-old mash the volume up on a tablet, that single feature justifies the whole product.
Battery and build are the other two pillars. Bluetooth 5.4 gives a claimed 60 hours of playtime — at four hours a day, that's roughly half a month between charges — and the charge itself takes about two hours over USB-C. When it does run flat, you plug in the included 3.5mm cable and keep going, which matters on a plane when there's no outlet in sight. The body is BPA- and PVC-free ABS that iClever says is 50% stronger than a standard build, with a reinforced button structure, rotating ear cups and a 10-level headband that adjusts to fit heads from about age two upward. At 149g with protein leather cushions, it's light enough that kids stop noticing it.
Who should buy it: parents buying a first real headphone, anyone shopping for a child aged 2+ who travels by plane or car, and gift-buyers who want one box that works with a phone, tablet, PC or school laptop. The 20Hz–20KHz range and 40mm dynamic driver with low-frequency compensation mean it sounds fuller than the price bracket usually suggests, though it's tuned for clarity, not bass slam. Who should skip it: adults wanting serious noise cancellation or spatial audio. This is passive isolation only — the cups block some ambient sound, nothing more. And if your search is the best spatial audio kids headphones for swimming, this isn't it; no Bluetooth headphone is a swimming product.
The Comecase case is a single-purpose object, and that's its charm. It's a hard EVA shell covered in PU leather, lined with a silky fluff that cradles a folded headphone so the cups don't scuff against each other. The listing calls out shockproof, semi-waterproof and crush protection — dust, scratches, scuffs and moisture are all named — and honestly, for a hard case, that's the correct list. The zipper is described as sturdy and long-wearing, which is the failure point on cheap cases, so it's good that it's addressed.
Compatibility is broad and specifically foldable-focused: Beats Solo 4, Solo3, Solo2, Studio Pro, Studio3 and Solo Pro, plus Glynzak, Picun B8 and P26, Mpow models, Elecder i39, Sony MDR-ZX110 and noot products K11, among others. The maximum compatible device size is about 7.5 inches, so if your headphones fold, there's a good chance they fit. Non-folding over-ears are a gamble — check your folded dimensions before ordering.
The extras are genuinely useful on a commute: a removable hand strap, a carabiner for clipping to a bag, and an internal mesh pocket for a charging cable or a USB adapter. It's light and compact enough for a backpack, carry-on or locker, and the pink and grey colorway is bright enough to spot instantly in a crowded bag.
Side-by-Side: Which Should You Choose?
• Best for a working headphone out of the box → iClever BTH22. It plays music; the Comecase doesn't.
• Best for protecting foldable headphones you already own → Comecase Hard Headphone Case. Hard EVA shell, fluff lining, shockproof and water-resistant.
• Best for young kids → iClever BTH22. 74dBA and 85dBA Safe Volume modes, 149g, age 2+, BPA- and PVC-free materials.
• Best for long battery life → iClever BTH22. Up to 60 hours, and a 3.5mm cable as a backup when the battery dies.
• Best for travel organization → Comecase. Hand strap, carabiner and a mesh pocket for cables.
• Best for airplane and road trips with a child → iClever BTH22. The wired fallback alone makes it the smarter carry-on pick.
• Best for school lockers and crowded commutes → Comecase. Crush and scuff protection is exactly what a bag needs.
• Best value → In my opinion, iClever BTH22 for buyers who need a device, Comecase for buyers who only need storage. Different jobs, both sensibly built for their job.
If you're buying for a child and you need something that actually makes sound, I'd buy the iClever BTH22. Safe volume limiting, 60 hours of battery, a wired backup and a fit that adjusts from toddler upward is a genuinely thoughtful combination, and it's the one I'd hand to a kid on a flight. I'd buy the Comecase Hard Headphone Case only if foldable headphones are already sitting on your desk and you're tired of replacing them. If your real goal is the best over ear headphones for swimming, step back — that's a waterproof-audio problem, and neither of these solves it.
FAQ
They're headphones whose ear cups rotate or hinge inward so the headset collapses into a smaller, flatter shape for storage. That folding action is exactly what makes a compact hard case like the Comecase practical — the case is sized for a folded headphone, not an open one.
Fold gently along the hinge the cups are designed to travel, don't twist the headband itself, and store the result in a hard case rather than loose in a bag. That last step is the whole point of the Comecase — the fluff lining and rigid shell keep the folded cups from pressing against anything heavy.
Hinge wear is usually mechanical, so check whether a screw, pin or clip has worked loose and whether the cup still clicks into position. If the plastic has cracked, replacement is typically the realistic route — which is why a protective hard case is cheaper than a repair in the long run.
