How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single bulk purchase that equips an entire classroom with wired, shareable headsets, choose Yunsailing 30; if you need one pair of fully wireless earbuds for workouts, commuting and personal listening, choose Arruilys True. These two products barely compete for the same buyer — one is a 30-unit classroom set, the other is a single set of true wireless earbuds. The right answer comes down to whether you're buying for a room full of students or for your own two ears.
• Yunsailing 30 — biggest strength: 30 wired on-ear headsets with microphones in one purchase, sized to fit kids, teens and adults, which makes it a natural fit for a whole class or lab.
• Yunsailing 30 — biggest trade-off: it's wired, has no active noise cancellation and no Bluetooth, so it's built for supervised, plugged-in settings rather than movement.
• Arruilys True — biggest strength: true wireless earbuds with up to 50 hours of total playtime via the charging case, a dual LED power display and an IPX7 waterproof rating.
• Arruilys True — biggest trade-off: it's a single personal pair, so it can't equip a group, and the in-ear design is a very different fit from an on-ear headband.
• Who each pick is for: Yunsailing 30 for teachers, schools, libraries, labs and tutoring centers buying in bulk; Arruilys True for one person who wants wireless earbuds for sport, travel and daily listening.
The Yunsailing 30 is a classroom kit first and a pair of headphones second. You get 30 wired headsets in white, each with a built-in microphone and an adjustable headband. The on-ear design with soft ear cushions is meant to be passed around — the headband adjusts across children, teens and adults, which is exactly what you want in a room where the equipment gets shared between grade levels, training groups or adult education classes.
The practical logic here is one headset per student. Instead of hunting for a working pair before an assessment or a multimedia lesson, a teacher can hand out the set and get straight to the activity. That's the real value of buying in a 30 pack: it removes the daily logistics problem of shared audio gear in a school, library, computer lab, tutoring center or exam room.
Who should buy it: anyone equipping a group — schools, tutoring centers, libraries, computer labs, exam rooms and training rooms — who wants a complete, cable-based set that needs no batteries and no setup. Who should skip it: a single user who wants wireless freedom, sweat resistance or something for the gym. This is a shared-resource product, not a personal one.
Arruilys True: Who It's For
The Arruilys True (model S27) is the opposite kind of product: one pair of true wireless in-ear earbuds for one person. The headline number is playtime — up to 50 hours of total listening with the charging case, plus a smart dual LED display that shows the battery status of both the earbuds and the case. If you've ever been caught out mid-commute with dead earbuds and no idea how much charge was left, that display is a genuinely useful detail, not a gimmick.
Sound comes from 13mm dynamic drivers, which is a larger driver than you'd typically expect in a compact earbud, and Arruilys positions the tuning around rich bass, clear vocals and crisp highs. Built-in microphones handle calls, and the connection runs on Bluetooth 5.3, which the spec sheet ties to faster pairing, lower latency and a more stable link. After the first pairing, the earbuds reconnect automatically when you open the case — a small thing that matters every single day.
The feature that most clearly separates these two products is durability in motion. The Arruilys True carries an IPX7 waterproof rating, meaning it's built to handle sweat, rain and splashes during workouts and outdoor use. Combined with the ergonomic in-ear fit and the included S/M/L ear tips, it's clearly aimed at running, training, commuting and travel. Touch controls on either earbud let you manage playback, volume, calls and a voice assistant without pulling out your phone, which is the whole point of going wireless in the first place.
Who should buy it: one person who wants earbuds for the gym, the commute, travel and everyday phone or laptop listening, and who values long battery life and water resistance. Who should skip it: anyone buying audio for a classroom, a lab or a group of any kind. A single pair of earbuds simply can't serve 30 students, and in-ear buds aren't ideal for shared supervised use.
Side-by-Side: Which Should You Choose?
• Buying for yourself only → Arruilys True. One pair, wireless, made for personal listening.
• Best for battery life and untethered use → Arruilys True. Up to 50 hours total with the case and a visible LED power readout.
• Best for shared, supervised environments → Yunsailing 30. Passive noise isolation keeps students focused while still letting them hear instructions.
• Best for workouts, running and rain → Arruilys True. The IPX7 rating and secure in-ear fit are built for sweat and weather.
• Best for plug-and-play classroom hardware → Yunsailing 30. A 3.5 mm wired jack and on-headset volume control work without Bluetooth, apps or batteries.
• Best for mixed ages in one room → Yunsailing 30. The adjustable headband is designed to fit kids, teens and adults.
• Best for calls on the move → Arruilys True. Bluetooth 5.3, built-in mics and touch controls keep your phone in your pocket.
If I were outfitting a classroom, lab or tutoring center, I'd buy the Yunsailing 30 — in my opinion the 30-unit count, adjustable fit and wired 3.5 mm simplicity are exactly what a shared teaching space needs, and there's nothing to charge or pair. If I were buying for myself, I'd take the Arruilys True: up to 50 hours of playtime, IPX7 water resistance and Bluetooth 5.3 make it the more useful personal product. These aren't really rivals — they solve different problems. Pick based on who's actually going to wear them.
No. The Yunsailing 30 is a 30 pack of wired on-ear classroom headsets with microphones and a 3.5 mm jack. The Arruilys True is a single pair of true wireless in-ear earbuds with a charging case. Different form factors, different buyers.
The Arruilys True, clearly. Its IPX7 waterproof rating, secure in-ear fit and included S/M/L ear tips are designed for sweat and movement, while the Yunsailing 30 is a wired, on-ear classroom headset with no water-resistance rating listed.
No. They're wired with a 3.5 mm jack, so there's no battery, no pairing and no charging routine — which is a big advantage when 30 units need to be ready for a lesson. The trade-off is you're tethered to the device.
The Arruilys True. It's a personal wireless product with up to 50 hours of total playtime and touch controls; the Yunsailing 30 only makes sense when you need audio for a group. Either way, check the current price on Amazon before deciding, since it isn't listed here.
