• iClever HS19 — biggest strength: A 2-level volume switch capped at 85dB, plus a 40mm dynamic driver setup and a sharing jack for two listeners on one device. In my opinion, that combination is the whole reason to pick it.
• iClever HS19 — biggest trade-off: It's a wired 3.5mm headphone with a folding over-ear build, so there's no charging to worry about but also no wireless freedom, and the cardboard case it ships with is packaging, not protection.
• Againmore Hard Headphone Case — biggest strength: A structured EVA shell with wave foam, a velvet lining and a separate mesh accessory pocket, sized around folded JBL headphones.
• Againmore Hard Headphone Case — biggest trade-off: It's an empty case. It contains no headphones, no cable and no adapter, and it's explicitly not crushproof or waterproof.
• Pick the iClever HS19 if you're buying headphones for a child and volume safety matters to you.
• Pick the Againmore case if you already own compatible JBL headphones and want somewhere safe to put them.
Start with what the HS19 is built to do. It's an over-ear wired headphone aimed at kids, and the headline feature is a switch that limits output to 85dB — the level the design targets to protect young ears during daily listening. There's a second setting too, so you're not locked into one loudness all the time. For a parent, that switch is the single most important thing on the spec sheet.
Comfort and portability are where the foldable design earns its keep. The round over-ear earcups use soft padding and PU material, and the whole thing weighs 172 grams — light enough that a child won't be fighting it on a long flight. It folds down for storage in a backpack or carry-on. Two things to be honest about: the included carrying case is cardboard, so it protects against dust more than against a backpack full of textbooks, and it's a corded headphone, so it won't suit a kid who wants to roam the house untethered. There's a 24-month warranty on the unit itself. If you want a wireless option, this isn't it — the wired connection is the point.
Who should buy it: parents of younger children, families who share one device, and anyone who wants volume limiting without paying for a smart app. Who should skip it: older kids who want Bluetooth, and adults who need a case that survives real abuse.
Againmore Hard Headphone Case: Who It's For
This is a single-purpose product, and it's honest about that. The Againmore case is a hard oval shell built to hold folded JBL headphones — specifically the Tune 510BT, 520BT, 720BT, 770NC and 670NC, plus the Live 770NC, 780NC, 680NC and 670NC. It is not a universal case, and Againmore says so plainly: check your folded dimensions and your headband setting before ordering, because headband adjustment changes how the headphone sits inside.
The interior is the interesting part. It measures 8.07 x 6.10 x 0.98 inches, deliberately calibrated to reduce excess movement without pressing on the earcups, headband or hinges. Wave-shaped foam in the lid fills the empty space from above, which is the detail that matters most in practice — the biggest cause of damage to folded headphones isn't a single drop, it's constant rubbing against a bag on a commute. The EVA shell resists dust, scuffs and light compression, and the velvet lining gives the earcups a soft contact surface rather than hard plastic.
Then there's the mesh pocket. Charging cables and adapters live up top, separated from the headband, which cuts down on tangles and on scratched earcups. Small thing, big quality-of-life difference.
On size, the exterior is 8.46 x 6.70 x 2.56 inches and weighs 4.8 ounces, so it slides into a backpack, carry-on, locker or desk drawer without bulking things out. There's a smooth zipper and an integrated carry handle. Two caveats worth repeating: it's splash-resistant at best and should never be submerged, and it is not crushproof or drop-proof — it's everyday protection, not a flight case. And the listing is case only. No headphones, no cables, no adapters. Note also that the description mentions a purple color in one place while the product data lists black; if color matters to you, confirm what you're receiving.
Who should buy it: anyone who already owns one of the compatible JBL models and wants to stop tossing them loose into a bag. Who should skip it: anyone looking for headphones, and anyone whose headphones fall outside that compatibility list.
• Shopping for a child → iClever HS19. The 85dB limit and lightweight 172g build are designed around younger listeners.
• Already own compatible JBL headphones → Againmore Hard Headphone Case. That's the entire use case.
• Need to share one device between two kids → iClever HS19, thanks to the built-in sharing jack.
• Need to protect folded headphones in a backpack → Againmore case. The EVA shell, wave foam and velvet lining are purpose-built for it.
• Want wireless listening → Neither, strictly speaking. The HS19 is wired; the Againmore case is an accessory.
• Best for long-haul travel with a child → iClever HS19, though I'd pair it with a sturdier case than the cardboard one included.
• Best for keeping cables and adapters tidy → Againmore case, because of the elastic mesh pocket.
• Best for a locker or desk drawer → Againmore case. The slim 2.56-inch profile and carry handle suit it.
My Verdict
Wired. It connects through a 3.5mm jack, which is why it works with tablets, computers and handheld consoles without pairing or charging.
It's designed around specific folded JBL Tune and Live models. Againmore advises comparing your folded headphone dimensions and headband setting before ordering, since the fit is calibrated rather than universal.
It resists everyday bumps, dust and light compression, but Againmore states it is not crushproof or drop-proof, and it should not be submerged. Treat it as daily-travel protection, not heavy-duty armor.
For the HS19, confirm your child's device has a 3.5mm jack. For the case, confirm your headphone model is on the compatibility list. Prices change, so check the current price on Amazon before deciding.
