If you want a simple, kid-friendly wired headphone with a share jack and a mic built into the cable, choose EarFun K1; if you need a school headset with a rotating boom mic, a mute button and a three-step volume limiter, choose SIMOLIO USB-C-Headphones Wired-Kids for-School.
• EarFun K1 — biggest strength: A straightforward USB-C kids headphone with a 40mm dynamic driver, an in-line mic and remote, a 3.5mm sharing jack, and a foldable, adjustable frame. In my opinion the cleanest pick for everyday listening and tablet time.
• EarFun K1 — biggest trade-off: Volume limiting is fixed at 85dB/94dB with no third quiet mode, there's no boom mic, and noise control is listed as none.
• SIMOLIO USB-C-Headphones Wired-Kids for-School — biggest strength: A genuine school headset: dual USB-C and 3.5mm connection, a 330° swivel boom mic with one-key mute, and a visible 75/85/94dB volume limiter.
• SIMOLIO USB-C-Headphones Wired-Kids for-School — biggest trade-off: More moving parts to keep track of — a boom arm, a volume switch and a dongle — and it's the fussier of the two for a child who just wants to plug in and listen.
• Who each is for: EarFun K1 for younger kids doing videos, music and casual tablet use; SIMOLIO for students who spend real time in online classes and need to be heard clearly.
The EarFun K1 is built around listening first and talking second. Inside are 40mm dynamic drivers with a 20Hz–20,000Hz range, 32 ohm impedance, 100dB sensitivity — numbers that describe a headphone designed to be easy to drive from a tablet, Chromebook or Switch without a dongle. The ear cups are over-ear with leather-and-plastic construction, and the headband stretches to fit different head sizes.
What makes it kid-friendly is the volume ceiling. EarFun lists an 85/94dB limit, which means you get a quieter setting for everyday use and a louder one for noisy environments. There's a microphone on the audio cable for online study and calls, plus in-line buttons for play/pause, answering and ending calls, and skipping tracks. The detail I like most is the 3.5mm sharing jack: a second pair of headphones plugs straight in, so two kids can watch the same thing without a splitter.
Buy it if you want one headphone that covers school, travel and downtime, and you value the foldable design for stuffing into a backpack. Skip it if your child's day is dominated by video calls — the cable mic is fine for occasional talking, but there's no boom arm to position near the mouth and no mute button on the microphone itself.
SIMOLIO's KD-1 is the opposite emphasis: it's a communication tool that also plays audio. The headline feature is the 330° rotating boom microphone, which swings to either side of the head and flips up out of the way when it isn't needed. There's a one-key mute right on the mic arm, which is exactly the kind of thing a kid in a Zoom class needs — and exactly the kind of thing a parent appreciates not having to troubleshoot.
The second headline feature is the three-level volume limiter. A visible switch lets you pick 75dB for bedtime audiobooks and sensitive ears, 85dB for regular school use, or 94dB for buses and planes where background noise is loud. That's one more step of control than a two-setting design gives you, and the switch being visible means you can see at a glance which mode your child is in.
Connectivity is the other strong point. There's a built-in USB-C plug for iPad, Chromebook, Samsung Galaxy, iPhone 15/16/17 and MacBook, plus a 3.5mm jack for Kindle Fire, school computers and airplane audio ports — no adapters required. Dual 40mm dynamic drivers handle the sound, the frame is stainless steel with a retractable headband and ultra-soft cushions, and it ships with a travel bag.
Buy it if your child is in online classes, needs to be heard clearly, and you want granular control over how loud things get. Skip it if you want the simplest possible pair — between the boom arm, the limiter switch and the dongle, there's more for a young child to manage.
• Best for microphone quality in class → SIMOLIO. A 330° boom mic with one-key mute beats a mic sitting on the cable for Zoom, remote lessons and video calls.
• Best for volume control → SIMOLIO. Three levels (75/85/94dB) versus two on the EarFun K1 means a true quiet mode for bedtime listening.
• Best for simplest everyday use → EarFun K1. Plug in, press play, done. No boom arm to position, no limiter switch to check.
• Best for sharing with a sibling or friend → EarFun K1. The 3.5mm sharing jack lets a second headphone plug in without a splitter.
• Best for device coverage → SIMOLIO. Dual USB-C and 3.5mm connection covers modern phones, tablets and laptops as well as school PCs and airplane ports.
• Best for portability → EarFun K1. The foldable design is built for being carried to school, on trips and back again.
• Best for durability on paper → SIMOLIO. Stainless steel in the frame and soft cushions suggest a headset meant to survive a full school year.
• Best for a younger child → EarFun K1. Fewer controls and a lighter 180g build suit a toddler or early-grade kid better.
If I were buying for a child who mostly watches videos, listens to music and occasionally joins a call, I'd pick the EarFun K1 — it's the simpler, more portable headphone and the sharing jack is genuinely useful. If the child is a student who lives in online classes and needs to be heard, I'd pick the SIMOLIO USB-C-Headphones Wired-Kids for-School instead. In my opinion the boom mic, mute button and three-level limiter are worth the extra fiddliness for anyone whose day revolves around being on a call. Two different jobs, two different answers.
How to connect USB-C wired headphones
Plug the USB-C connector directly into a USB-C port on your device. The EarFun K1 uses a USB-C cable connection for devices like Kindle Fire tablets, Switch, Chromebook and PC. The SIMOLIO headset has a built-in USB-C plug for iPad, Chromebook, Galaxy phones, iPhone 15/16/17 and MacBook, plus a 3.5mm jack and a USB-C to 3.5mm dongle for older gear.
How to use USB-C wired headphones on Mac
Connect the USB-C plug to a USB-C port on the Mac. The SIMOLIO headset lists MacBook among its compatible devices, and its 3.5mm jack is a fallback if you'd rather use the analog port. The EarFun K1 is a USB-C wired headphone, so it works the same way on a Mac with a USB-C port.
How to connect USB wired headphones to Xbox
Both of these are wired headsets, but neither data sheet lists Xbox as a compatible device. EarFun names Switch, Chromebook, PC and Kindle Fire; SIMOLIO names iPad, Chromebook, Galaxy, iPhone 15/16/17, MacBook, Kindle Fire, school computers and airplane audio ports. Check your console's audio options before assuming either will work.
How to connect USB wired headphones to MacBook
Use the MacBook's USB-C port for the direct connection. SIMOLIO explicitly lists MacBook compatibility for its USB-C plug; EarFun's USB-C cable is described as compatible with type-C devices generally. For a MacBook with only USB-C ports, the SIMOLIO's included dongle also lets you run 3.5mm audio where needed. Prices change often, so check the current price on Amazon before deciding.
