• FBLFOBELI Headphone Cases EVA — biggest strength: A hard EVA shell that's shockproof and waterproof, with double zippers and a built-in mesh pocket for accessories.
• FBLFOBELI Headphone Cases EVA — biggest trade-off: It's an empty case with no device inside, and its fit is aimed at specific JBL on-ear models rather than anything with larger cups.
• TuneFlux Kids Headphones — biggest strength: Volume capped at 85dB for hearing protection, plus a foldable, adjustable, lightweight on-ear design made for kids.
• TuneFlux Kids Headphones — biggest trade-off: It's wired only (3.5mm jack), has no active noise control, and the on-ear plastic build is aimed at children rather than adults.
• Choose FBLFOBELI if you already own compatible JBL headphones and want to protect them at home or on the road.
• Choose TuneFlux if you're buying a first pair of headphones for a child and safety volume limits matter more than wireless freedom.
This is a storage and protection product, not an audio product. FBLFOBELI makes a hard carrying case out of EVA — ethylene vinyl acetate — which is the same class of foam-like material you find in molded protective shells. That material choice is the whole story here: it's stiff enough to resist crushing, it's listed as shockproof, and it's rated waterproof. If a bag gets rained on, or a backpack gets tossed in a car trunk, the case is doing the work, not the headphones.
The interior is designed around a compact footprint. There's a mesh pocket built into the lid for the small stuff — a charging cable, an adapter, maybe a spare pair of eartips — and the case closes with a double-zipper setup rather than a single pull. Double zippers sound like a minor detail until you've fought with a stuck single zipper on a plane tray table. The whole thing weighs about 0.19 kg and is described as compact and lightweight, so it adds bulk to a bag without adding much heft. The stated compatible device size maxes out at 7.8 inches, and the listed compatible headphone models are the JBL T450BT and JBL Tune 500BT, with the product also positioned around the wider JBL Tune and Live on-ear family.
Who should buy it: someone who owns those JBL on-ear models and wants a dedicated home for them instead of letting them rattle loose in a bag. Students, commuters, and frequent travelers fit that profile well.
TuneFlux Kids Headphones: Who It's For
The TuneFlux Kids Headphones are the opposite kind of product: an actual listening device, engineered around a child's needs. The headline feature is the 85dB volume ceiling. That number is the point. Volume limiting means the loudest the headphones can go is capped, which is the practical way to protect young ears from the kind of accidental blast that happens when a kid grabs a volume slider. The sensitivity is listed at 85 dB, consistent with that design intent.
The audio side is more capable than you might expect for a kids' product. It uses a dynamic driver with a frequency range of 20 Hz to 20,000 Hz and 32-ohm impedance — a standard, easy-to-drive spec that any phone, tablet, or school laptop with a 3.5mm jack can handle. TuneFlux describes the sound as high-fidelity and stereo, and the specs back up that it's a genuine full-range driver rather than a tinny toy speaker.
Comfort and durability get real attention too. This upgraded version (model USA-F8p) adds improved headband padding, and the design is foldable and adjustable, which matters when a headphone has to survive being shoved into a school bag between uses. It's built lightweight to reduce strain during long sessions, and the materials are described as sturdy enough for daily use by active kids. The 3.5mm wired connection is universal — no pairing, no charging, no dead battery in the middle of a car ride.
Who should buy it: parents buying a first or second pair of headphones for a child, especially for school, tablets, and travel where a wired connection is simpler and more reliable. The Black/Red colorway and gift-friendly framing fit that use case.
Who should skip it: adults who want wireless freedom, anyone who needs noise cancellation (the noise control field is listed as none), and anyone who dislikes cables. It's a wired, on-ear, plastic-bodied kids' headphone — no more, no less.
Side-by-Side: Which Should You Choose?
• Best for a child's first headphones → TuneFlux Kids Headphones. 85dB volume limit and an adjustable, foldable fit.
• Best for travel with loose gear → FBLFOBELI Headphone Cases EVA. The mesh pocket and double zippers keep cables and small accessories contained.
• Best for school and tablet use → TuneFlux Kids Headphones. The universal 3.5mm jack works with basically any device a classroom or home tablet uses.
• Best for long listening sessions → TuneFlux Kids Headphones. Lightweight construction and upgraded headband padding reduce strain.
• Best for durability against the elements → FBLFOBELI Headphone Cases EVA. The EVA shell is rated waterproof; the TuneFlux plastic body carries no such rating.
• Best for wireless freedom → neither. The FBLFOBELI is an empty case, and the TuneFlux is wired only.
• Best if you own JBL Tune 500BT / T450BT → FBLFOBELI Headphone Cases EVA. Those are the listed compatible models.
• Best if you need noise cancellation → neither. The TuneFlux lists no noise control, and a case doesn't cancel anything.
In my opinion, these two don't compete — they solve different problems, and the honest answer is that you might buy both for the same household. If I had to pick one for a typical shopper reading this comparison, I'd lean toward the TuneFlux Kids Headphones, because it's a complete product that does a job on its own: safe volume, comfortable fit, foldable, and wired for simplicity. The FBLFOBELI case is genuinely well thought out for what it is, but it only makes sense if you already own the specific JBL models it fits. If that's you, it's a smart buy. If it isn't, it's a box for headphones you don't have.
FAQ
Probably not. Its compatible device size tops out at 7.8 inches and the listed models are the JBL Tune 500BT and T450BT. If your headphones have larger cups, the fit may be too tight to be useful.
No. They're wired only, connecting through a standard 3.5mm jack, so there's no battery to charge and no pairing step. That makes them easy for kids to use independently with tablets, laptops, and school devices.

They're capped at 85dB by design for hearing protection, so they won't get very loud. The 32-ohm impedance and 20 Hz–20 kHz range mean the sound itself is full-range, but the volume ceiling is the limiting factor for adult use.
