If you want a school-ready, volume-limited headset that also gives you a boom mic and a real 3.5mm fallback, choose SIMOLIO USB-C Wired-Kids-Headphones for-School; if you need lightweight open-ear earbuds that stay put during workouts and commutes, choose Jiunai Open Ear USB.
• SIMOLIO's biggest trade-off: it's an over-ear headset with a cord and a boom arm, so it's more gear to carry and not something you'd wear running.
• Jiunai's biggest strength: open-ear hooks that stay locked on your ears with a 15° adjustable fit, a cord clip, and 16mm dynamic drivers — great for movement and awareness.
• Jiunai's biggest trade-off: no boom mic, no volume limiting, and only a USB-C jack, so older 3.5mm school computers and airplane ports are out.
• Choose SIMOLIO if you're buying for a student, a kid on Zoom lessons, or anyone who needs a mic and hearing protection.
• Choose Jiunai if you want featherweight wired earbuds for the gym, the commute, or all-day background listening.
This is a purpose-built study and communication headset. The headline feature is the 330° rotating boom mic, which swings to either side and flips up and out of the way when you're done talking. There's a one-key mute button right on the mic arm, so silencing yourself in a Zoom class or a video call takes one press — no hunting through software settings. If your day involves speaking as much as listening, that combo matters more than any spec sheet number.
The second thing that stands out is the volume limiter. SIMOLIO uses a three-position switch with visible settings: 75dB for quiet bedtime audiobooks and sensitive ears, 85dB for everyday school use, and 94dB to cut through the noise of a bus or a plane cabin. For a parent, that switch is the whole point — it's a physical control you can set and forget, not an app you have to trust. Dual 40mm drivers handle the audio, and the retractable headband plus soft over-ear cushions are designed to fit kids and adults without pinching.
Connection is where this headset gets genuinely flexible. The built-in USB-C plug covers iPad, Chromebook, Samsung Galaxy, iPhone 15/16/17, and MacBook, while the 3.5mm jack picks up Kindle Fire, school computers, and airplane audio ports. There's also a USB-C to 3.5mm dongle in the box, so modern phones without a headphone jack are covered too. Graphite Black, over-ear, wired, one-year manufacturer warranty.
Jiunai Open Ear USB: Who It's For
The Jiunai is a different animal entirely. These are open-ear earbuds with 15° adjustable over-ear hooks that curve gently around your ears and hold firm. The pitch is simple: nothing goes inside your ear canal, so you keep surrounding awareness while you listen, and the hooks mean you're not constantly pushing a bud back in mid-run. A small cord clip attaches to your clothing to cut down on cable drag and the thumping noise a swinging wire can create, and a zipper case is included for tossing in a bag.
Inside, you get 16mm dynamic drivers with a 16-ohm impedance, 126dB sensitivity, and a frequency response up to 20,000Hz. In practical terms, that's a loud, easy-to-drive earbud that doesn't need much power from a phone or laptop to get going. There's an in-line control with a microphone, so you can take calls and adjust volume without touching your device. The housing mixes ABS, silicone, and TPE, and the whole package is listed as Black.
The catch is the connector. It's USB-C only — plug and play, but USB-C only. No 3.5mm fallback, no dongle mentioned, so an older school desktop with a round audio jack simply won't work. There's also no volume limiting and no boom mic; the mic lives on the inline control, which is fine for a quick call but not the same as a mic arm you can position near your mouth. Warranty is three months.
Who should buy it: office workers, students, remote professionals, runners, gym-goers, and anyone who wants lightweight wired earphones that stay put during active and everyday use. Who should skip it: younger kids who need hearing protection, and anyone whose main device still uses a 3.5mm jack.
Side-by-Side: Which Should You Choose?
• Best for hearing protection → SIMOLIO. The 75/85/94dB switch is the single most important feature here for kids.
• Best for calls and online classes → SIMOLIO. A 330° boom mic with one-key mute beats an inline mic every time.
• Best for device compatibility → SIMOLIO. USB-C plus 3.5mm plus a dongle covers far more hardware than USB-C alone.
• Best for open-ear awareness → Jiunai. Nothing blocks your ear canal, so you hear traffic and surroundings.
• Best for travel and airplanes → SIMOLIO. The 94dB mode and 3.5mm jack both exist for exactly that scenario.
• Best for all-day lightweight wear → Jiunai. Open-ear buds with hooks are the lighter, less bulky option.
• Best for a MacBook owner who does both → SIMOLIO. It's the one that plugs into a MacBook and still works with everything else in the house.
In my opinion, SIMOLIO USB-C Wired-Kids-Headphones for-School is the one I'd buy for most people reading this. It solves more problems at once: a real microphone with instant mute, a physical volume limiter, and dual connectivity that covers a MacBook, an iPad, a school PC, and an airplane seat. The Jiunai is genuinely good at what it's built for — open-ear, secure, lightweight — but it's a narrower tool. If your priority is running and staying aware of your surroundings, take the Jiunai. If your priority is school, calls, and protecting young ears, take the SIMOLIO.
how to use headphones for macbook
Plug the USB-C connector straight into a USB-C port on the MacBook, or use the included USB-C to 3.5mm dongle if you'd rather go through the headphone jack. The SIMOLIO is wired, so there's nothing to pair — the MacBook should recognize it as an audio output and input right away. Then pick your volume mode on the switch and set the boom mic where it picks up your voice.

For a wired USB-C headset like the SIMOLIO, connection is physical: insert the plug and check Sound settings for the input and output device. The Jiunai is also wired USB-C and plug-and-play, but it has no 3.5mm option, so it needs a USB-C port or a USB-C adapter. Neither product uses Bluetooth, so there's no pairing step at all.
how to connect headphones macbook air
A MacBook Air works the same way — USB-C in, or the dongle into a 3.5mm jack if the model has one. Because both headsets are wired, the MacBook Air will treat them as a standard audio device. If audio doesn't route automatically, switch the output manually in your sound settings.

Same routine on a MacBook Pro: plug into USB-C, or use the 3.5mm route with the SIMOLIO's dongle if that's easier. The SIMOLIO's inline mute button is handy for muting yourself mid-call without leaving the app. The Jiunai's inline control handles volume and calls instead.
