• TCJJ Unicorn Kids Headphones — biggest strength: a 3.5mm wired connection that works with almost any phone, tablet, laptop or school device, plus a microphone for online classes and video chat. Biggest trade-off: the cable is fixed, so there's no folding and no USB-C option.
• Candy Bila USB C Kids — biggest strength: an 85dB volume limit paired with a larger 40mm dynamic driver and a foldable, adjustable build. Biggest trade-off: the USB-C plug only fits USB-C devices — no 3.5mm jack, so older gear is out.
• Who TCJJ is for: kids who want a sparkly unicorn headset for school, calls and everyday listening on a standard headphone jack.
• Who Candy Bila is for: kids using USB-C iPads, tablets and laptops where you want a safer volume ceiling and a bigger driver.
• The core split: 3.5mm versatility and a mic (TCJJ) versus USB-C convenience, volume limiting and a larger driver (Candy Bila).
The TCJJ Unicorn Kids Headphones are built around a very specific idea: a fun, giftable wired headset that plugs into just about anything. The connection is a standard 3.5mm jack, and a 1.2m (3.9 ft) cable is included in the box. That length is the sweet spot for a kid sitting at a desk or holding a tablet — long enough to move a little, short enough not to tangle into a knot. The earcups sit on the ear rather than around it, the shell is ABS plastic, and the headband is adjustable, so it can grow with a child instead of being replaced every year.
What it does best is the theme plus the mic. The design carries a unicorn horn and two ears, with sequins on the headband and ears that catch the light. The colour treatment is galvanized, which the spec sheet notes as fade-resistant. In my opinion, this is the pair you buy when the headphones need to feel like a present, not a piece of hardware. The microphone is the practical half of that: it handles video chat, answering calls and online classes, which is exactly what a school-age kid needs. The materials are described as BPA-free, impact-resistant and non-toxic, which matters for something that will get dropped.
Who should buy it: a child who wants a unicorn headset for school, remote lessons and talking to family, and whose devices still have a 3.5mm jack. The 32 ohm impedance and 20 Hz frequency response mean it's easy to drive from a phone or tablet without any extra gear.
Candy Bila USB C Kids: Who It's For
The Candy Bila USB C Kids headphones go the other direction: modern port, safer listening, bigger sound hardware. The connector is USB Type-C, and the box includes the USB-C plug headset and a user manual. That single spec decides most of the buying question. If your kid is on a USB-C iPad, a newer tablet or a laptop, this plugs straight in with no dongle and no adapter to lose.
The headline feature is the 85dB sensitivity rating. That's the volume ceiling baked into the design, and for parents it's the reason to pick this pair over a generic set. Alongside it sits a 40mm dynamic driver — noticeably larger than what you'd expect in a small kids' headset — with a 20 Hz to 20,000 Hz frequency range and 32 ohm impedance. In practice, a bigger driver usually means fuller sound with more low end, which helps with music and movies, not just voice. The earcups are over-ear with a circular shape, so they surround the ear rather than press on it, and the headband is both adjustable and foldable. Foldable matters more than people think: it's the difference between headphones that live in a bag and headphones that live on a desk.
Who should buy it: a child on USB-C devices, especially one who listens to music and watches video, and a parent who wants a volume limit built into the hardware. The over-ear fit and foldable frame suit longer sessions and travel.
Who should skip it: anyone whose devices are still 3.5mm-only, and anyone who specifically wants a microphone for calls and classes — the spec sheet doesn't list one here. If your kid needs to talk during lessons, that's a real gap.
Side-by-Side: Which Should You Choose?
• Best for device compatibility → TCJJ Unicorn Kids Headphones. A 3.5mm jack fits phones, tablets, laptops and school hardware; the Candy Bila needs USB-C.
• Best for sound hardware → Candy Bila USB C Kids. A 40mm driver with a 20 Hz–20 kHz range beats a smaller on-ear setup on paper.
• Best for calls and online classes → TCJJ Unicorn Kids Headphones. It's the only one of the two with a built-in microphone.
• Best for travel and storage → Candy Bila USB C Kids. The foldable headband is built for packing; the TCJJ keeps its fixed 1.2m cable.
• Best for fit over the ear → Candy Bila USB C Kids. Over-ear cups instead of on-ear, for kids who dislike pressure on the ear.
• Best as a gift → TCJJ Unicorn Kids Headphones. The unicorn theme and sequins are the whole point of the design.
• Best for a younger child's first headset → TCJJ Unicorn Kids Headphones. Light, on-ear, wired and simple, with no port decisions to make.
If I were buying for a kid who plugs into a USB-C tablet or laptop and I wanted a volume limit baked in, I'd buy the Candy Bila USB C Kids. The 85dB ceiling, the 40mm driver and the foldable adjustable frame are a genuinely useful combination, and it's the pair I'd pick for music and movies. But if the child needs a microphone for classes and calls, or their devices still use a 3.5mm jack, I'd buy the TCJJ Unicorn Kids Headphones instead — it's the more flexible of the two, and it's the one that feels like a gift. Decide on the port and the mic first, and the choice makes itself. Either way, check the current price on Amazon before you commit.
how to adjust headphones
On both of these, adjustment is done at the headband, not in an app. The TCJJ Unicorn Kids Headphones and the Candy Bila USB C Kids both list an adjustable headband, so you slide each side in or out until the earcups sit comfortably. Candy Bila adds a foldable hinge, which is for storage rather than fit.
how to adjust headphones on iphone
If you're using these with an iPhone, the adjustment you can make on the phone itself is volume, through the side buttons or Control Center. The TCJJ pair connects via its 3.5mm jack, which on modern iPhones needs an adapter, while the Candy Bila uses USB-C. Physical fit is still adjusted by hand at the headband on both.
how to adjust headphones volume
Volume depends on the device, not the headset — use the phone, tablet or laptop controls. The difference between these two is the ceiling: the Candy Bila USB C Kids is rated at 85dB sensitivity, which limits how loud it can go, while the TCJJ sheet lists sound isolation rather than a fixed decibel cap.
how to adjust headphones sound
Neither product includes an app or EQ controls, so sound adjustment happens in your device's audio settings. What separates them is the hardware: the Candy Bila uses a 40mm dynamic driver with a 20 Hz–20,000 Hz range, while the TCJJ uses a smaller on-ear dynamic driver at 32 ohm with a 20 Hz frequency response.
