If you want one pair of over-ear headphones that switches between wireless Bluetooth, FM radio and a micro SD card for everyday music, calls and travel, choose iJoy Headphones Over Ear; if you need a bulk set of 30 wired on-ear headsets to equip a whole classroom for lessons, exams and speaking exercises, choose Yunsailing 30.
• iJoy Headphones Over Ear — biggest strength: true all-rounder connectivity. Bluetooth with a 10-meter range, a 3.5 mm wired jack, FM radio and a micro SD card slot, plus a built-in mic for hands-free calls.
• iJoy Headphones Over Ear — biggest trade-off: it's a single pair of headphones, so it only serves one listener at a time, and the stated battery life figures (8 hours average, 20 hours of wireless connection) mean you'll be reaching for the charging cable regularly.
• Yunsailing 30 — biggest strength: it's a 30-pack, so one purchase outfits an entire class. Adjustable headband, on-ear cushions and a 3.5 mm jack keep it simple for shared use.
• Yunsailing 30 — biggest trade-off: it's wired only, with no Bluetooth or wireless mode at all, and the on-ear design offers passive isolation rather than deep over-ear sealing.
• Who each pick is for: iJoy is for one person who wants flexibility in how they listen; Yunsailing 30 is for a teacher, school or training center buying for a group.
The iJoy Headphones Over Ear is built around choice. Instead of locking you into one way of listening, it gives you four: Bluetooth wireless, a 3.5 mm wired connection, an FM radio receiver and a micro SD card slot. That last one is unusual at this end of the market and genuinely useful — you can load music onto a card and listen without pairing anything or touching your phone. The 5-button control panel handles play/pause, answering and ending calls, track skipping, volume and switching between Bluetooth and FM mode, so most of what you need sits on the earcup rather than on your phone screen.
Comfort is where the design details matter. The memory protein ear cups sit over the ears rather than pressing on them, and the enclosure is designed to isolate audio — a passive sound-isolation approach, not active noise cancellation. The adjustable headband and foldable build make it easier to toss into a bag for travel, though note the travel case is sold separately. There's also a built-in mic for hands-free calls, which makes it a reasonable pick if you take meetings or calls on the move. The stated frequency range of 20 Hz to 20,000 Hz and dynamic drivers cover the full audible spectrum, and the tuning leans toward deep bass for music.
One more thing worth flagging: iJoy states a 6-month exchange warranty through Pranx covering breakage or damage with a free replacement. That's a meaningful detail for a headset aimed partly at kids and workouts, where rough handling is normal.
Yunsailing 30: Who It's For
Yunsailing 30 is not really a headphone in the consumer sense — it's classroom infrastructure. The 30-pack format exists so a teacher can assign one headset per student and have the whole room ready for a lesson, assessment or multimedia activity without hunting for spares. That single design decision shapes everything else about it. It's wired via a 3.5 mm jack, which is exactly what you want in a supervised setting: no pairing, no dropouts, no battery to charge, no student connecting to the wrong device. Plug in and it works.
The adjustable headband is explicitly sized to span kids, teens and adults, which matters in schools where the same set gets used across grade levels, in libraries, computer labs, tutoring centers and adult education programs. The on-ear cushions are lightweight and designed to reduce pressure during long sessions — a real consideration when a class is sitting through an exam or a multi-hour computer-based test. The build uses an ABS shell, chosen for durability, with soft ear pads and a stated 32-ohm impedance and dynamic drivers covering 20 Hz to 20,000 Hz. The microphone is the other half of the pitch: more tests, quizzes and learning apps now require students to speak as well as listen, and a built-in mic on every headset makes that possible without passing a single shared microphone around the room.
Who should buy it: schools, libraries, computer labs, tutoring centers and training rooms that need a full set at once, and anyone who wants a simple wired headset that a child can use unsupervised without settings to fiddle with. Who should skip it: a single adult buyer who wants wireless freedom, FM radio, or media playback from a memory card. None of that exists here — it's a wired 3.5 mm headset, full stop. Also note the noise control field lists active noise cancellation while the product description explicitly states these are passive noise-isolating headphones, not active noise-canceling. I'd treat the description as the accurate one and plan around everyday distraction reduction, not silence.
• Best for wireless freedom → iJoy Headphones Over Ear. Bluetooth with a 10-meter range, no cable required.
• Best for equipping a group → Yunsailing 30. A 30-pack covers an entire class in one go.
• Best for varied listening sources → iJoy Headphones Over Ear. Bluetooth, 3.5 mm wired, FM radio and micro SD card all in one headset.
• Best for shared, supervised use → Yunsailing 30. Wired-only means no pairing, no batteries and no settings for students to change.
• Best for hands-free calls → a tie, for different reasons. iJoy has a built-in mic for wireless calls; Yunsailing 30 puts a mic on every headset so 30 students can speak into their own.
• Best for long listening sessions without charging → Yunsailing 30. It has no battery at all, so it never runs out mid-lesson.
• Best for one person who travels → iJoy Headphones Over Ear. Foldable design, over-ear cups and a wired fallback when the battery is drained.
• Best for durability across age groups → Yunsailing 30. ABS shell and an adjustable headband sized for kids through adults.
For a single buyer, I'd take the iJoy Headphones Over Ear. In my opinion the flexibility is what wins: Bluetooth when you want it, a 3.5 mm cable when the battery dies, FM and micro SD for listening without a phone, and over-ear cups with memory protein padding for longer sessions. It's a genuinely versatile one-pair solution, and the 6-month exchange warranty softens the risk on a headset that will get knocked around.
The Yunsailing 30 only makes sense if you're buying for a group. If you're a teacher or lab manager, it's the obvious pick — 30 wired headsets, no charging, no pairing, sized to fit everyone in the room. But for one person, 30 headsets is 29 too many.
Both. It supports Bluetooth wireless with a 10-meter range and also includes a 3.5 mm jack for wired listening, plus FM radio and a micro SD card slot.
Thirty. It's a bulk classroom set with 30 individual headsets, each with a 3.5 mm jack and a built-in microphone.
The product description states they are passive noise-isolating, not active noise-canceling — the soft ear cushions reduce everyday classroom distractions without fully blocking outside sound, which suits supervised settings.
The iJoy Headphones Over Ear. It's a single over-ear pair with wireless and wired modes, a built-in mic, FM and micro SD support, so it covers music, calls and travel. Check the current price on Amazon before deciding, since that's the factor most likely to tip your choice.
