If you want active noise cancelling for flights and noisy commutes in a foldable over-ear package, choose MONODEAL Active Noise Cancelling; if you need a kid-safe, volume-limited foldable headset with cat ears and a sharing port, choose QearFun Kids Cat Ear. These are two very different headphones built for two very different listeners, and the foldable design each one uses tells you a lot about where it's meant to live.
• MONODEAL Active Noise Cancelling — biggest strength: Active noise cancelling circuitry rated to cut up to 85% of background noise, plus a foldable frame, carrying case, airplane adapter and up to 20 hours of battery life.
• MONODEAL Active Noise Cancelling — biggest trade-off: It's a wired, adult-oriented headphone with a full-size around-ear fit, and you're asked to take it off every couple of hours for ear comfort.
• QearFun Kids Cat Ear — biggest strength: A switchable 85dB/94dB volume limiter, a built-in 3.5mm share port so two kids can listen from one device, and a sparkly foldable frame with interchangeable dino, cat or unicorn styling.
• QearFun Kids Cat Ear — biggest trade-off: It's wired only, has no active noise cancelling, and the decorative ears and glitter finish are clearly aimed at children rather than adults.
• Who each pick is for: MONODEAL for travelers and commuters who want quiet; QearFun for parents buying for kids ages 3 and up.
The MONODEAL headphone is built around one job: making a loud environment quieter. Its internal noise reduction circuitry is designed to cancel up to 85% of background noise, and the brand points squarely at airplane travel as the reason it exists. That's why the box includes an airplane adapter — the dual-prong plug older aircraft seat systems use — along with a carrying case and a headphone splitter for sharing a single jack. If you fly, take trains, or work near constant ambient noise, that combination is unusually complete for a single wired headset.
The foldable part matters here more than it might seem. A folding frame plus a hard-ish plastic carrying case means the headphone collapses down into something you can drop in a backpack or a carry-on pocket instead of wearing around your neck through the airport. At a listed weight that the brand describes as lighter than a large phone, it's clearly designed to disappear into your bag until you need it. The 40mm dynamic drivers cover a 20Hz–20kHz range, which is the standard full-range window, and the brand frames the tuning as bass-forward with balanced output. The around-ear memory foam pads and adjustable headband are meant to fit a range of head sizes.
Two things to know before you buy. First, it runs on a rechargeable battery rated for up to 20 hours of continuous use, but it also works passively with noise cancelling off — so a dead battery doesn't strand you, it just means you lose the ANC. Second, this is not a kids' product. The age range is listed as adult, there's no volume limiter, and the brand itself suggests taking the headphones off every two hours to let your ears rest. I'd recommend it for frequent flyers, students in noisy dorms, and anyone who wants wired reliability without charging anxiety. I'd steer parents and small children elsewhere.
The QearFun headset is designed from the ground up for children, and the safety features are the headline. There's a switchable volume limiter that caps output at 85dB or 94dB, which is the kind of concrete protection a parent actually cares about when handing a child a pair of headphones. The built-in microphone handles online classes and family calls, and the built-in 3.5mm share port lets two kids listen from one tablet or laptop at the same time without a splitter — genuinely useful on road trips and on the couch.
The styling is the hook: glittery cat ears, or a dino or unicorn variant, finished in an electroplated gradient. That's a deliberate choice to make the headset something a kid wants to wear, and the age range starts at 3. The build backs it up with memory foam earcups, a reinforced adjustable headband, and a tangle-free nylon braided cable meant to survive being yanked and twisted. It's wired with a standard gold-plated 3.5mm jack, so it plugs straight into iPads, Kindle Fires, Chromebooks and laptops with no pairing step.
On sound, it uses 40mm dynamic drivers with 32 ohm impedance across a 20Hz–20kHz range — the same driver size as the MONODEAL, but tuned for kids with the limiter in the chain. The foldable design keeps it packable for school bags and travel. The honest trade-off: no active noise cancelling, so it won't quiet a plane cabin, and the cat-ear look is not something most adults will want to wear. I'd buy this for a child who needs a safe, durable, fun headset — not for an adult who needs silence.
Side-by-Side: Which Should You Choose?
• Best for flights → MONODEAL Active Noise Cancelling. It ships with an airplane adapter; the QearFun does not.
• Best for kids → QearFun Kids Cat Ear. Switchable 85dB/94dB volume limiting, ages 3+, kid-proof materials.
• Best for sharing audio → QearFun Kids Cat Ear. Its built-in share port lets two listeners use one device; MONODEAL instead includes a separate headphone splitter.
• Best for battery independence → MONODEAL Active Noise Cancelling. Up to 20 hours per charge, and it still plays passively once the battery runs down.
• Best for plug-and-play simplicity → QearFun Kids Cat Ear. Wired 3.5mm with no charging at all.
• Best for portability → both, roughly. Each uses a foldable frame; MONODEAL adds a carrying case, QearFun stays lightweight for a backpack.
• Best for adult ears → MONODEAL Active Noise Cancelling. The QearFun is sized and styled for children.
For most readers landing on this comparison, I'd buy the MONODEAL Active Noise Cancelling. In my opinion, the combination of up to 85% noise reduction, an airplane adapter, a carrying case, a foldable frame and up to 20 hours of battery is the more useful package for an adult who travels or commutes — and the passive mode means it never becomes a paperweight. I'd only switch to the QearFun if the listener is a child, in which case the volume limiter and share port are the features that actually matter. Two different buyers, two different answers.
FAQ
what are foldable headphones
how to fold foldable headphones
On a folding design like these, you rotate each earcup flat against the headband and then fold the headband inward at its hinge until the cups meet. The goal is to reduce the footprint so the headset fits in a bag or case without stressing the joints.
how to fold headphones
Most folding headphones only move in one direction at the earcup swivel and one at the headband hinge. If a joint resists, stop — you're at the end of its travel, and forcing it is how hinges break. Fold gently, and store the headset in its case when you can.
how to fix foldable headphones
Fixes depend on the failure, but common issues are a loose hinge screw, a cable that's been yanked, or a pad that's come loose. Check the warranty first: MONODEAL lists a one-year replacement-or-refund warranty, and QearFun lists a one-year manufacturer warranty, so contact support before attempting a repair yourself.
