How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one comfortable, foldable pair of wired on-ear headphones with a built-in mic and inline volume control for a single kid, student or commuter, choose AILIHEN C8; if you need to outfit a whole classroom, computer lab or testing room with 30 matching adjustable on-ear headsets in one go, choose Yunsailing 30.
• AILIHEN C8 — biggest strength: a single, gift-ready on-ear headset with soft cushioned earcups, a 3.5 mm wired connection, a built-in mic, inline volume and call control, and a foldable design that collapses into the palm of your hand — in a Rose Gold finish.
• AILIHEN C8 — biggest trade-off: it is one headphone, not a set, so it solves a personal listening problem rather than a room-sized one; and its noise control is sound isolation, not active noise cancellation.
• Yunsailing 30 — biggest strength: it ships as a 30-pack of lightweight, adjustable on-ear headphones with microphones, a 3.5 mm jack and inline volume control — built for shared, multi-station environments like classrooms, libraries, labs and testing rooms.
• Yunsailing 30 — biggest trade-off: it is bulk equipment in one color (Black, metal stem), sold as a flat-pack of 30, so a single buyer who only needs one pair is paying for 29 they will not use.
• Who each is for: AILIHEN C8 for one person who wants a comfortable, portable, mic-equipped wired headset; Yunsailing 30 for a teacher, school, lab manager or program coordinator who needs a matching class set in one purchase.
The AILIHEN C8 is a wired on-ear headphone built around a single listener. It uses a 3.5 mm jack, so it plugs straight into a phone, Chromebook, laptop, tablet or desktop with no pairing, charging or dongle involved. That alone makes it a sensible pick for schoolwork, online study, video calls and casual music, because there is nothing to configure — you plug in and you are listening.
Comfort is clearly the design priority here. The earcups are soft and cushioned and shaped to sit on the ear rather than around it, and the headphone weighs about 180 g. The earcups fold up so the whole thing collapses into the palm of your hand, which matters if it lives in a backpack or gets tossed in a bag between classes and commutes. You also get a built-in microphone plus inline volume and call control on the cable, so answering a call or nudging the volume does not mean reaching for your device.
Who should skip it? Anyone who needs to equip a room. If you are buying for 20 or 30 students, one C8 is not a plan — you would need to buy many, and they would not match. Also skip it if you specifically want active noise cancellation; the C8 uses sound isolation, which reduces what reaches your ears passively rather than electronically cancelling it. And if you want wireless freedom, this is a wired-only headphone by design.
Yunsailing 30: Who It's For
The Yunsailing 30 is not really a headphone so much as a headphone program in a box. It arrives as 30 matching on-ear headsets with microphones, all Black with a metal stem, all wired with a 3.5 mm jack and inline volume control. If you have ever tried to assemble a class set one pair at a time, you already understand the appeal: one order, 30 identical units, no mismatched spares.
The design language is institutional and that is the point. The enclosure is ABS with rubber, the earpieces are on-ear, and the headphones are described as lightweight and adjustable — the adjustability is what lets the same headset fit a range of head sizes across a class without you hand-fitting each one. Sound isolation keeps outside noise down so students can focus, and the microphone supports spoken work, language practice and standardized testing where a headset mic is required. The brand lists libraries, computer labs, businesses, museums, art galleries and universities as target environments, which tells you the intended use case is shared, multi-station listening rather than personal ownership.
The trade-offs are real and worth stating plainly. The whole set weighs about 1.61 kg, so this is a bulk shipment meant to be unpacked and distributed, not carried around. It is one color and one style — there is no personalization, no color choice, no travel case. And the age range is listed as Adult, so if you are buying for young children, that is a signal to check the fit and size carefully before ordering, as the brand itself advises.
Who should buy it? A teacher, school IT coordinator, lab manager, testing coordinator or anyone running a program where many people listen at once and headsets go missing or break. Who should skip it? A single user who wants one pair of headphones. Buying 30 to get one makes no sense.
Side-by-Side: Which Should You Choose?
• Best for a classroom, lab or testing room → Yunsailing 30. Thirty matching adjustable headsets with mics, ready to distribute.
• Best for portability → AILIHEN C8. At roughly 180 g with earcups that fold into your palm, it is the one you actually carry.
• Best for a fixed, shared station → Yunsailing 30. Lightweight and adjustable, designed to be left at a desk and re-fitted by the next user.
• Best for a gift or personal accessory → AILIHEN C8. The Rose Gold finish and faux-leather trim make it feel like something you chose, not something you were issued.
• Best for matching spares and replacements → Yunsailing 30. Identical units mean a broken pair can be swapped without anyone noticing a difference.
• Best for device compatibility at home → Either. Both use a standard 3.5 mm jack, so both work with phones, laptops, tablets, Chromebooks and desktops that still have a headphone port.
• Best if you hate wireless setup → Both. Neither requires pairing or charging; both are wired with inline volume control.
One thing both share: neither offers active noise cancellation. Both list sound isolation, which is a passive reduction of outside noise. If you were hoping to block out a plane engine, neither is that product — but both will take the edge off a noisy room.
If I were buying one pair for myself or my kid, I would buy the AILIHEN C8. It is lighter, it folds down small enough to live in a bag, it comes with a mic and inline controls, and it is designed as a personal headset from the ground up — which is exactly the job.
If I were the one responsible for a room full of learners, I would buy the Yunsailing 30 without hesitating. Thirty adjustable, mic-equipped, matching headsets in one order is the only sane way to equip a class, and the adjustability is the spec that makes it work across different head sizes. In my opinion, matching the product to the scale of the job matters more here than any single spec.
how to adjust headphones volume
On both the AILIHEN C8 and the Yunsailing 30, volume is handled through inline control on the cable — the control type on each is listed as Volume Control, with a touch control method. So you adjust loudness on the headset cord itself, and you can also use your device's own volume buttons or on-screen slider.
how to adjust headphones
For fit, the Yunsailing 30 is explicitly described as adjustable, which is how one headset accommodates different head sizes in a shared setting. The AILIHEN C8 is on-ear with cushioned earcups and a foldable design, so you adjust it by seating the earcups comfortably over your ears and folding it away when you are done.
how to adjust headphones on iphone
Both headsets connect with a standard 3.5 mm jack, so on an iPhone you would plug into the headphone port where one exists, or use the appropriate adapter for newer iPhones that lack one. Once connected, use the inline volume control on the cable or the iPhone's own volume buttons to adjust levels.
how to adjust headphones sound
Sound adjustment on these models comes down to your source device — neither offers an app or active sound processing, since both are wired with sound isolation rather than electronic noise control. You shape the sound with your phone, laptop or Chromebook's equalizer and volume settings, and the inline control handles quick level changes.
