• AILIHEN's biggest strength: a 3.5mm wired connection with an inline microphone and a multi-function button, so there is nothing to charge and nothing to pair before class starts.
• AILIHEN's biggest trade-off: it is an on-ear, sound-isolating headset built for seated use, not for sweat, rain or heavy movement.
• TRAUSI's biggest strength: a fully wireless Bluetooth design with an IPX7 waterproof rating and a touch-control interface, which suits movement and moisture.
• TRAUSI's biggest trade-off: earbuds need charging, sit inside the ear canal, and its documentation is thinner, with a shorter stated warranty period.
• Pick AILIHEN if you are buying for a student, a classroom, or anyone who wants a plug-and-play corded headset.
• Pick TRAUSI if you want cord-free earbuds for the gym, commuting or general phone listening.
The AILIHEN MS300 is a wired on-ear headset, and the wiring is the whole point. A standard 3.5mm jack plugs straight into a Chromebook, laptop, tablet or smartphone with no pairing step, no battery level to check, and no chance of a dropped Bluetooth connection halfway through a lesson. For a parent handing a device to a kid, that simplicity is worth a lot. There is no app, no charging routine to nag about, and no mystery when the audio stops.
Around that jack, AILIHEN has built a genuinely practical school headset. The nylon cable is described as tangle- and tear-resistant, which matters because cables are usually the first thing to fail on a kid's headphones. The inline microphone sits on that cable, and the multi-function button handles play, pause, answering, hanging up and track skipping — so a student can join a video class, mute themselves between answers and start a music break without touching the laptop. The headband slides to fit different head sizes, which means the same pair can move from a younger kid to a teenager, and the whole thing folds down small enough to slide into a backpack.
Weight is where this design earns its keep. At 6 oz, it is light enough that the on-ear fit is unlikely to become a burden over a long school day, and the padded ear cushions and adjustable headband are there specifically for extended sessions. The purple finish, achieved with a coated surface, is aimed squarely at kids who care what their gear looks like.
Who should buy it: parents buying for school, remote learning or travel; anyone who wants a corded headset with a mic that just works; and shoppers who would rather not manage yet another battery. Who should skip it: runners, gym-goers and anyone who wants earbuds that stay put during sweaty activity — this is a seated, corded, on-ear design, and that is exactly what it is good at. AILIHEN also states a one-year coverage period covering manufacturing, delivery and normal wear in the first year, which is a reasonable thing to know when buying for a kid.
TRAUSI's i27 model is a different animal entirely: wireless in-ear earbuds in Soot Black, built around a Bluetooth connection and a touch-control surface. There is no cable and no jack. You pair them with a phone, and you tap the earbud housing instead of pressing a button. If your priority is not being tethered to anything while you move, that is the appeal.
The headline spec here is IPX7 waterproofing. That is a meaningful rating for earbuds — it is aimed at sweat, rain and the kind of moisture that comes with a hard gym session — and it is the clearest signal about who these are for. The listing names the gym directly, and the combination of wireless freedom, a waterproof enclosure and touch controls lines up with that use case rather than with classroom work.
The design details fill in the rest. These are in-ear buds made with a plastic enclosure, described as lightweight, and the package includes two earbuds plus an owner's manual. They are listed as compatible with smartphones, which is the natural partner for a Bluetooth earbud. TRAUSI lists a 90-day warranty period, which is noticeably shorter than AILIHEN's stated one-year coverage, so factor that into how you think about long-term ownership.
What the data does not give you is depth: there is no stated impedance, frequency response, driver type or battery figure in the product information, and the feature list is essentially one line. Practically, that means you are buying on the core proposition — wireless, waterproof, touch-controlled earbuds for phone use — rather than on a detailed spec sheet. Who should buy it: gym-goers, runners and anyone who wants cord-free earbuds for workouts and commuting. Who should skip it: students who need a plug-in headset for a school laptop, younger kids who are hard on small loose objects, and anyone who does not want another device to charge.

• Best for warranty confidence → AILIHEN Kids Headphones. The stated one-year coverage beats TRAUSI's 90 days.

In my opinion, the AILIHEN Kids Headphones are the safer buy for most people reading this comparison. The wired 3.5mm design removes the two things that most often ruin a kid's headphone day — a dead battery and a dropped connection — and the adjustable headband, foldable body, inline mic and published audio specs give a buyer more to evaluate. I would pick TRAUSI only if the job is specifically wireless earbuds for the gym or workouts, where IPX7 waterproofing and a cord-free fit genuinely matter more than a jack. Check the current price on Amazon for both before you decide, since that is the one variable this comparison deliberately leaves out.
FAQ
how to wired headphones work
how to use wired headphones with iphone
You plug the 3.5mm jack into the port or adapter on your phone. AILIHEN's cable includes a microphone and a multi-function button for play, pause, answering calls and skipping tracks, so most control happens on the cable rather than on the screen.
how to fix wired headphones no sound
Work through the simple causes first: make sure the jack is pushed fully into the port, check the device volume and output settings, and try a different device to isolate whether the problem is the headphones or the source. Cables are the usual failure point, which is why AILIHEN uses a tangle- and tear-resistant nylon cable and backs the set with one year of coverage for manufacturing, delivery and normal wear issues.
Not automatically. TRAUSI's wireless earbuds suit phones, gyms and movement, and they are IPX7 waterproof, but they need charging and are small enough to lose. AILIHEN's wired headset pairs instantly with a school laptop and never needs a battery, which is usually the bigger advantage for classroom use.
