If you want a wired, school-ready headset with a hard volume ceiling and a share port for two kids on one device, choose awatrue AT2; if you need wireless freedom, a folding travel design, and up to 40 hours of playtime per charge, choose EarFun K2.
• awatrue AT2 — biggest strength: true wired 3.5mm connection plus a built-in sharing jack, so it works with Chromebooks, tablets, PCs and laptops with zero pairing, charging or dropouts, and two kids can listen from one device.
• awatrue AT2 — biggest trade-off: it's on-ear, corded and has no battery, so it's tethered to the device and there's no wireless mode for travel.
• EarFun K2 — biggest strength: Bluetooth 5.4 with up to 40 hours of playtime and a foldable over-ear build that packs down for school bags and trips.
• EarFun K2 — biggest trade-off: it runs on a battery you have to remember to recharge, and the box includes two units, so it's a multi-kid purchase rather than a single pair.
• Who each is for: awatrue AT2 for younger students who need a reliable, shareable, corded headset for class and homework; EarFun K2 for kids and teens who want wireless listening on the move or in a two-kid household.
The awatrue AT2 is built around one idea: remove every point of failure between a kid and their lesson. It's a wired on-ear headphone with a 3.5mm plug, so it connects to Chromebooks, tablets, PCs and laptops the moment you push it in. No pairing screen, no dead battery, no "why isn't it working" five minutes before class starts. The built-in microphone handles Zoom calls and language apps, and the 40mm dynamic drivers with 32-ohm impedance and a 20 Hz–20 kHz range are a sensible spec set for speech clarity and everyday listening rather than audiophile bass.
The other half of the story is the volume limiting. The AT2 caps output at 85dB or 94dB, with 85dB framed as study mode for classroom work and 94dB as travel mode for car rides and louder environments. For parents, that switch is the whole point — it's a hardware ceiling, not a suggestion, so a kid can't quietly crank it to maximum on a long road trip.
Then there's the share port. A second 3.5mm jack lets a sibling or friend plug in a second headset and hear the same audio, no splitter required. That's genuinely useful for shared tablets, group projects and movie nights in the back seat.
Who should buy it: parents of younger school-age kids who want one dependable, corded headset for class, homework and video calls, and households where two kids often share a screen. It's also a strong fit if you're tired of charging yet another device. Who should skip it: anyone who wants wireless listening, or a teen who'd find a cord and an on-ear fit limiting. If you need Bluetooth, this isn't the one.
The EarFun K2 takes the opposite approach: cut the cord. It's a Bluetooth 5.4 over-ear headphone with up to 40 hours of playtime on a single charge and a 2.5-hour recharge over USB-C. That's the headline number — 40 hours is roughly a full school week of daily use between charges, which matters a lot less if you remember to plug it in, and a lot more if you don't. Bluetooth 5.4 also means a stable connection to iPads, Chromebooks and other Bluetooth devices, so a kid can move around the room, the car or the house without dragging a cable.
The K2 also keeps the safety story: volume is limited to 85/94dB, matching the WHO-recommended level, so the wireless freedom doesn't come at the cost of hearing protection. The 40mm drivers and 20 Hz–20 kHz range are the same basic spec class as the AT2, tuned for balanced stereo with clear vocals and full bass rather than flat classroom audio.
Comfort and durability are clearly where EarFun spent effort. The memory foam headband and earpads are over-ear, which means the cups sit around the ears instead of pressing on them — usually the more comfortable option for longer sessions and for kids who wear glasses. The headband is designed to twist and bend without breaking, and the whole thing folds down small for a backpack. EarFun lists it for ages 3–18, so it stretches from toddler to teen. Two things to note: the box contains two headphones, and there's a 3.5mm cable included for when the battery runs out — so it's not purely wireless, it just treats wired as the backup rather than the default.
Who should buy it: families with two kids, or anyone who wants wireless listening for school, travel and tablet time, plus the comfort of over-ear memory foam. Who should skip it: parents of a single young child who just needs a cheap, bulletproof classroom headset, or anyone who wants a purely plug-and-play experience with no charging routine.
• Best for a no-charge, no-pairing school setup → awatrue AT2. Wired 3.5mm works instantly with Chromebooks, tablets, PCs and laptops.
• Best for wireless freedom and travel → EarFun K2. Bluetooth 5.4 with up to 40 hours per charge.
• Best for sharing audio between two kids on one device → awatrue AT2. The built-in share jack needs no splitter.
• Best for a two-kid household in one purchase → EarFun K2. It ships as a two-pack.
• Best for long-session comfort, especially with glasses → EarFun K2. Over-ear memory foam cups instead of on-ear pads.
• Best for the youngest kids → EarFun K2. The adjustable band is listed for ages 3–18, and the foldable build suits small backpacks.
• Best for strict, switchable hearing protection in both products → a tie. Both cap at 85dB study mode and 94dB travel mode.
• Best for kids who lose or forget chargers → awatrue AT2. No battery means nothing to recharge.
In my opinion, the right pick comes down to one question: cord or no cord. If your kid is in early grades and the headphones basically live in a backpack next to a Chromebook, I'd buy the awatrue AT2 — the wired connection is one less thing to troubleshoot, the share port is a genuinely thoughtful extra, and the 85/94dB switch keeps the volume honest without you policing it. If your kid is older, moves between rooms and devices, or you need two pairs at once, I'd buy the EarFun K2 for the 40-hour battery, Bluetooth 5.4 and over-ear comfort. Neither is the "wrong" answer — they're built for different kids.
how to disable volume control on wired headphones
There's no universal switch for this, because volume limiting is usually built into the headphone rather than the device. On the awatrue AT2, the volume cap is a hardware feature with an 85dB study mode and a 94dB travel mode — you switch between those two levels, but you can't remove the ceiling entirely. That's intentional: the limit exists to protect young ears, so treat it as a fixed design choice rather than a setting to turn off.
do earbuds have volume control
Many do, but it varies by model. In-ear and on-ear headphones often include inline or on-cup buttons, and the awatrue AT2 lists volume control with a button controller. Note the distinction, though: having a volume control isn't the same as having volume limiting. The AT2 has both an adjustable control and a hard 85/94dB ceiling, so a kid can lower the volume but can't push it past the safe maximum.
Yes. EarFun includes a 3.5mm audio cable in the box, so if the battery runs down you can plug in and keep listening in the traditional wired way. Just keep in mind the K2 is designed primarily as a Bluetooth headphone, so wired mode is the backup rather than the main event — and the 3.5mm jack still relies on the headphone's own volume limiting.
The awatrue AT2 is the simpler answer for sharing, because its built-in share jack lets a second headset plug straight in with no extra splitter. The EarFun K2 takes the opposite route: it ships as a two-pack, so each kid gets their own pair and connects wirelessly to their own device. If sharing a single screen is the goal, go AT2; if separate devices are the goal, go K2.
