If you want a compact on ear headphones setup you can actually protect when you travel, choose FBLFOBELI Hard Case Replacement; if you need the compact on ear headphones themselves for flights, choose Kemoterner Headphones. That's the whole split in one line. One is the shell that keeps a headset safe in a bag; the other is the headset you wear. I'll break down which one belongs in your carry-on for flights, and who each is really built for.
• FBLFOBELI Hard Case Replacement — biggest strength: a shockproof, water-resistant EVA shell with a mesh pocket, built specifically to fit a Microsoft Modern Wireless Headset or Philips Coolplay kids on-ear set.
• FBLFOBELI Hard Case Replacement — biggest trade-off: it's a case only. No headphones inside, and it fits a narrow list of models, so it's useless if your headset isn't on that list.
• Kemoterner Headphones — biggest strength: a foldable wired on-ear pair with a 3.5mm plug, a tangle-resistant cord and a 40mm dynamic driver, aimed squarely at travel and school use.
• Kemoterner Headphones — biggest trade-off: it's wired, so there's no Bluetooth and no charging — you're tethered to whatever has a 3.5mm jack.
• Who each pick is for: the FBLFOBELI case is for someone who already owns a compatible headset and wants it to survive the bottom of a bag. The Kemoterner pair is for someone who needs the headphones themselves, cheaply and simply, for a flight or a classroom.
This is a protective carrying case, not audio gear. It's molded from EVA — the same foamy, semi-rigid stuff you find in better electronics cases — and FBLFOBELI lists it as durable, shockproof and water resistant. In practice that means the shell takes the knocks so your headset doesn't, and a light rain or a spilled drink in your bag isn't an instant problem.
The design is deliberately compact: roughly 8.5 by 7.3 by 2.6 inches, double-zippered, with a mesh pocket inside for a cable, a dongle or a charging brick. It weighs about 0.23 kg, so it adds very little to a backpack. The compatibility list is short and specific — the Microsoft Modern Wireless Headset and the Philips Coolplay kids on-ear headphones. That specificity is the point: it's cut to fit those shapes, not a generic pouch.
Buy it if you own one of those compatible headsets and you're tired of it getting scratched or crushed in transit — especially if you pack a bag tightly for flights. Skip it if you need actual headphones, or if your set isn't on the compatibility list. In my opinion, a hard case is one of those purchases that feels boring until the day it saves a headset, and this one is built for exactly that job. Just confirm your model against the list before you commit.
The Kemoterner set is the opposite kind of product: it's the thing you put on your head. It's a wired on-ear pair with a 3.5mm plug, which means it works with anything that still has that jack — smartphones, tablets, laptops, Kindles, MP3 players and, importantly for travel, in-flight entertainment systems. No pairing, no battery, no charging cable to lose.
The sound side is spec'd reasonably for the money: a 40mm dynamic driver, 40 ohm impedance and 110 dB sensitivity. Those numbers suggest it'll get loud enough off a phone or a seat-back screen without needing a separate amp. The earcups are on-ear with circular pads and a padded headband, and Kemoterner calls out fatigue-free wear over long sessions. Passive noise cancellation is listed, which in a wired on-ear design means the physical seal of the cushions doing the work — not active electronics.
The travel angle is where it earns its place. The headset folds, the cord is braided and tangle-resistant, and you can hang it around your neck when you're not using it. It weighs about 230 g. Buy it if you want a simple, foldable, wired pair for flights, commuting or school and you don't want to think about batteries. Skip it if you need wireless freedom, active noise cancellation, or a mic for calls — none of that is in the spec sheet.
• You already own a compatible headset and want it protected → FBLFOBELI Hard Case Replacement. That's literally what it's for.
• You need the headphones themselves → Kemoterner Headphones. The case won't play anything.
• Best for flights → Kemoterner Headphones. The 3.5mm plug works with seat-back entertainment, and folding means it packs flat.
• Best for in-flight audio without charging → Kemoterner Headphones. Wired means no battery anxiety on a long haul, unlike rechargeable neckband headphones or bluetooth sleep headphones you'd have to top up.
• Best for keeping gear intact in a crowded carry-on → FBLFOBELI Hard Case Replacement. Shockproof EVA and a water-resistant shell.
• Best for kids' on-ear sets → FBLFOBELI Hard Case Replacement, provided the set is a Philips Coolplay kids model it's cut to fit.
• Best for school, tablets and laptops → Kemoterner Headphones. Wide 3.5mm compatibility and a tangle-resistant cord.
• Best if you want to carry both → both. The case's mesh pocket is for accessories, not a second headset, so pair the Kemoterner set with a compatible case only if it fits.
For flights specifically, I'd buy the Kemoterner Headphones. If you're boarding a plane and you need to actually hear something, a case does nothing for you — the wired 3.5mm plug, foldable frame and tangle-resistant braided cord are exactly what a travel pair should be, and there's no battery to babysit. The FBLFOBELI case only makes sense as a second purchase, and only if you already own one of the two headsets it's molded for. In my opinion, buy the headphones first; buy the case when you have something worth protecting.
FAQ
They can be, and the Kemoterner pair is built with that in mind: soft ear cushions and a padded headband, which Kemoterner describes as fatigue-free even over long sessions. Fit is adjustable, so the main variable is how the circular pads sit on your particular ears.
They suit people who want to stay aware of their surroundings, but neither product here is an open-ear design. The Kemoterner set is a closed on-ear pair with passive noise cancellation, and the FBLFOBELI item is a storage case, not audio gear at all.
I can't point you to an open-ear model from these two, because neither is one. If open-ear is a hard requirement, look elsewhere; if you mainly want a foldable wired pair for flights, the Kemoterner Headphones fit that brief well.
