If you want a wired, volume-limited pair that keeps a child's ears safe during online classes and homework, choose Candy Bila Kids Headphones; if you need a lightweight, sweatproof wireless headset for workouts, calls and everyday office use, choose itayak Behind. Both are foldable and easy to stow, but they solve completely different problems — one is built around a child's safety on a 3.5 mm cable, the other around a hands-free Bluetooth life on the move.
• Candy Bila biggest strength: A wired 3.5 mm connection with a hard 85/94 dB volume ceiling, in-line media and call controls, and a mic — a simple, predictable setup for kids.
• Candy Bila biggest trade-off: Wired-only. No Bluetooth, no rechargeable battery, and the plastic over-ear build is aimed at children rather than adult commuters or gym-goers.
• itayak Behind biggest strength: Bluetooth 5.0 wireless freedom, roughly 37 g of weight, an IPX5 sweatproof design, and a built-in battery rated for more than 11 hours of music or 14 hours of talking per charge.
• itayak Behind biggest trade-off: Passive noise cancellation only and no audio jack at all, so you're fully dependent on a charged battery and a Bluetooth source.
• Pick Candy Bila if you're buying for a kid who needs safe volume on a tablet, laptop or school device.
• Pick itayak Behind if you want a foldable wireless headset you can wear behind your head for workouts, errands and hands-free calls at the office.
The Candy Bila is a wired, over-ear headphone with a 3.5 mm jack, a dynamic driver covering 20 Hz to 20,000 Hz, and 32 ohm impedance — modest specs that are perfectly matched to the kind of low-power devices kids actually use, like tablets, laptops and PCs with a standard headphone socket. The headline feature is the volume limiter: you can set the output ceiling to 85 dB or 94 dB, which is the single most useful thing a parent can control on a child's headphone. Everything else follows that same kid-first logic.
In my opinion, this is the right pick for parents who want zero setup friction: plug in, hand it over, done. There's no pairing, no charging, and no chance of a child wandering into a volume level that hurts. Skip it if you need wireless audio, if you're buying for an adult, or if you want a headphone for running and sweaty workouts — a wired plastic over-ear with sound isolation isn't built for that. Also skip it if your device has no 3.5 mm jack and you don't want to deal with an adapter.
itayak Behind: Who It's For
The itayak Behind is a completely different animal. It's a behind-the-head wireless headphone built around Bluetooth 5.0, with a stated range of about 10 metres (roughly 33 ft), one-step pairing to a device named "itayak-910", and compatibility with phones, tablets and anything else Bluetooth-enabled. There's no jack at all — this is wireless or nothing.
What stands out to me is the weight: about 37 g. That's the kind of number that changes how you use a headphone. You wear it behind your head, the earbuds sit in your ears, and the design is meant to stay put without falling out. Add an IPX5 sweatproof rating and it becomes a genuinely useful training partner — the kind of thing you can wear through a run, a gym session or a sweaty commute without worrying about moisture getting inside.
The other big lever is battery: more than 11 hours of music playback, 14 hours of talking time and 200 hours of standby on a single charge. There are five push buttons for power, volume, track skipping, play/pause, call answer/hang-up/reject, and waking Siri or Google Assistant. Noise control is passive, meaning the fit itself blocks some outside sound rather than active cancellation. It folds down, ships with a protective carrying case, and comes in blue.
So who is it for? Anyone who wants a hands-free headset they can wear for hours without noticing it — runners, gym-goers, delivery drivers, warehouse staff, and people who take a lot of calls while moving around. It's also a sensible pick for anyone who wants an open, behind-the-head fit rather than bulky over-ear cups. Skip it if you need guaranteed safe volume limits for a small child, if you want a wired fallback for a device with no Bluetooth, or if you specifically want active noise cancellation for a noisy open-plan office.
• Best for safe listening with kids → Candy Bila Kids Headphones. The 85/94 dB limiter and wired simplicity are the whole point.
• Best for battery life and wireless freedom → itayak Behind. More than 11 hours of music and 14 hours of talk time on one charge, with no cable to snag.
• Best sweatproof headphone for office and gym crossover → itayak Behind. IPX5 and 37 g make it far more comfortable for movement than a plastic over-ear.
• Best for online classes and homework → Candy Bila Kids Headphones. The mic, in-line remote and 3.5 mm plug work instantly with tablets, laptops and PCs.
• Best for hands-free calls while walking around → itayak Behind. Five buttons, assistant activation and a 10 m Bluetooth range.
• Best for travel and storage → itayak Behind. It folds into a supplied carrying case and weighs almost nothing.
• Best for a no-charge, no-pairing setup → Candy Bila Kids Headphones. It draws nothing from a battery and never needs pairing.
• Best touch control wireless headset for office → neither, strictly speaking. Both use physical controls (in-line remote on the Candy Bila, push buttons on the itayak), not touch panels — worth knowing if touch is a must-have for you.
For office use and anything active, I'd buy the itayak Behind. It's wireless, it weighs almost nothing, it survives sweat, and its battery covers a full working day of calls and music without a cable tying you to your desk. That combination is hard to beat for the money you'd spend. If, on the other hand, the headphone is for a child — school, online lessons, car journeys — I'd buy the Candy Bila Kids Headphones instead, because the volume limiter protects young ears in a way no adult-focused headset does. My honest read: buy for the person, not the spec sheet. Check the current price on Amazon before you commit, since that's the one variable that can flip the decision.
FAQ
The built-in rechargeable battery is rated for more than 11 hours of music playback, around 14 hours of talking time and 200 hours of standby on a single charge. That's enough for a full day of office calls plus a workout.
Yes, that's what it's designed for. It has an IPX5 sweatproof rating, weighs about 37 g, and the behind-the-head fit is meant to stay secure so the earbuds don't fall out while you move.
The itayak Behind relies on passive noise cancellation, so it blocks some sound through fit alone but won't silence a loud open-plan room. The Candy Bila uses sound isolation for a similar effect. If you need serious noise blocking, neither is an active cancellation headphone — set your expectations accordingly.
No pairing at all. You plug the 3.5 mm jack in and it works immediately, which is exactly why it suits younger kids and shared school devices.
