How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, foldable on-ear pair that works with almost any school device and is built for library sessions on a Chromebook, choose ELECDER i37; if you need a USB-C over-ear headset with a built-in mic and a volume ceiling for kids, choose Candy Bila USB C Kids.
• ELECDER i37 — biggest strength: a gold-plated 3.5mm jack plus a 4.9 ft tangle-free cord that plugs into basically any Chromebook, tablet, laptop or phone in a library or classroom.
• ELECDER i37 — biggest trade-off: it's wired only, so there's no wireless freedom and no microphone for calls or online classes.
• Candy Bila USB C Kids — biggest strength: USB-C plug-and-play with a built-in DAC, plus an HD mic and inline controls for online classes and video calls.
• Candy Bila USB C Kids — biggest trade-off: it only works with USB-C audio ports — no 3.5mm and no Lightning, so older devices are out.
• Pick ELECDER i37 if you want maximum device compatibility and a lightweight foldable for school bags.
• Pick Candy Bila USB C Kids if you have a modern USB-C iPad or tablet and want a mic plus a safe volume limit.
The ELECDER i37 is the "just works everywhere" option. It's an on-ear, wired headphone with a standard 3.5mm jack, which means it connects to Chromebooks, tablets, laptops, smartphones, DVD players and Kindles without any adapter or setup. For a student who bounces between a library desktop, a personal tablet and a school Chromebook, that plug-and-play simplicity is the whole point. The 4.9 ft tangle-free cord is long enough to move around a bit at a shared table or swap seats on a plane without yanking the plug out.
Comfort and safety are clearly the design priorities here. The headband folds and adjusts, the ear pads are cushioned, and the materials are lead-free and BPA-free. The on-ear cushions are built to soften background noise like classroom chatter while still letting a kid hear what's going on around them — a sensible trade-off for a child in a public space. The ear cups also help younger users learn left/right orientation, which matters more than people admit when you're handing a device to a six-year-old.
Who should skip it? Anyone who wants wireless. The i37 is wired only — no Bluetooth, no microphone, no inline call handling in the spec sheet. If your kid does online classes, takes video calls or games with voice chat, this isn't the tool. It's also not for USB-C-only tablets or newer iPads that dropped the headphone jack. At 160 g it's light, but it's still an on-ear design, so a child who wants full ear coverage should look at an over-ear model instead.
The Candy Bila USB C Kids is built for one specific modern setup: a USB-C device. It uses a built-in DAC to connect directly to iPad Pro, iPad Air, iPad mini, recent iPad models, Android tablets, Chromebooks, laptops and phones that support USB-C audio. No dongle, no adapter — plug in and go. The flip side is strict: it will not work with Lightning ports or a 3.5mm jack, so if your household still runs older gear, this is the wrong pick.
What sets it apart is the combo of a microphone and a volume ceiling. There's an HD mic with a one-button inline remote for play/pause, answering calls and skipping tracks, which makes it genuinely useful for online classes, homework, video calls and gaming. The 40mm dynamic drivers handle clear voices and balanced stereo sound. Just as important, it adheres to an 85/94dB safe volume range, so it can cut through airplane engine noise or a busy room without pushing sound levels that are hard on young ears.
The over-ear build uses cloud-soft memory foam that fully surrounds the ear, which the brand positions as a plus for glasses-wearers since it avoids temple pressure. The sliding headband expands for a secure fit across toddlers, growing kids and teens, and the whole thing folds for travel. The housing is ABS plastic in a gradient red finish.
Who should skip it? Anyone with a 3.5mm-only device, any older iPad with Lightning, and any kid who just wants the cheapest universal option. It's also over-ear, so it runs bulkier than a compact on-ear pair — fine in a backpack, less ideal if you want something that disappears into a pocket.
• Best for device compatibility → ELECDER i37. The 3.5mm jack covers Chromebooks, laptops, tablets, phones, Kindles and DVD players.
• Best for modern USB-C tablets and iPads → Candy Bila USB C Kids. The built-in DAC means a direct connection with no adapter.
• Best for online classes and calls → Candy Bila USB C Kids. The built-in mic and one-button inline remote are made for it.
• Best for a quiet library session on a school laptop → ELECDER i37. Standard jack, long cord and on-ear isolation suit shared study spaces.
• Best for protecting young ears → Candy Bila USB C Kids. The 85/94dB safe-volume design is the clear pick.
• Best for glasses-wearers → Candy Bila USB C Kids. The over-ear memory foam surrounds the ear instead of pressing on it.
• Best for travel and packing → either, honestly. Both fold; the i37 is the lighter, more compact-feeling option at 160 g.
• Best if you're not sure what your kid's device has → ELECDER i37. The 3.5mm jack is the safer bet across mixed hardware.
One thing both share: a 32 ohm impedance and a dynamic driver, so neither needs an amp and both will run fine straight off a laptop or tablet. If you're weighing cost, the honest answer is that value depends on current pricing, which changes — check the current price on Amazon for each before you commit.
For a library-focused student setup, I'd buy the ELECDER i37. In my opinion, the 3.5mm jack is the deciding factor: it works with the widest range of school and home devices, the foldable on-ear design is light and packable, and the cord is long enough for real study sessions. The Candy Bila USB C Kids is the better buy if your kid lives on a USB-C iPad or Chromebook and needs a mic for classes and calls — the safe-volume limit and over-ear comfort are real advantages. But if you want one wired, foldable pair that just plugs in anywhere, the i37 is my pick.
No. The i37 is a wired headphone with a 3.5mm jack and a 4.9 ft cord. There's no Bluetooth. If you specifically want a wireless foldable, neither of these is that — both are wired.
No. It connects only to USB-C audio ports through its built-in DAC. It's not compatible with Lightning ports or a 3.5mm jack, so check your device's port before buying.
The Candy Bila USB C Kids, because it has a built-in mic and inline controls for calls and muting. The ELECDER i37 has no microphone, so it's listen-only.
The Candy Bila USB C Kids is designed around an 85/94dB safe volume range, which is the more protective option. The ELECDER i37 relies on passive on-ear sound isolation rather than a volume ceiling, so how loud it gets depends on the device it's plugged into.
