How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired classroom set you can hand out to a whole group, choose Yunsailing 18; if you need a wireless, sleep-friendly headband pair for two people, choose ZRUHIG 2-Pack.
• Yunsailing 18 — biggest strength: 18 individually wrapped wired over-ear headphones in one box, built for class sets, testing centers and shared student use.
• Yunsailing 18 — biggest trade-off: wired only, with a fixed 3.5 mm jack and no noise control, so it needs a compatible port on every device you plug into.
• ZRUHIG 2-Pack — biggest strength: wireless Bluetooth 5.4 headband headphones with ultra-thin speakers and an adjustable magic tape fit — no in-ear pressure, no cable.
• ZRUHIG 2-Pack — biggest trade-off: you only get two units, and the fabric band design is aimed at sleep, travel and light sport rather than bulk handouts or standardized testing.
• Who each pick is for: Yunsailing 18 for teachers, schools and anyone equipping a room; ZRUHIG 2-Pack for sleepers, side sleepers and travelers who want two spare bands.
The Yunsailing 18 is a bulk play, and it says so right in the design. You get 18 over-ear headphones, each one individually wrapped in its own bag. That single detail tells you most of what you need to know about the intended buyer: someone who needs a stack of identical, ready-to-hand-out units, not one premium pair. A teacher setting up a listening station, a testing coordinator, a computer lab manager — that's the audience.
The build is practical rather than precious. The shell is ABS, the 1.2 meter (about 3.94 feet) cable is PVC, and the ear pads are PU leather with soft cushioning. In my opinion that combination is exactly right for shared, repeated use: nothing here is trying to be delicate, and the materials are chosen to resist corrosion and everyday wear rather than to feel luxurious. The headband is adjustable, so it fits a range of head sizes, and it rotates 90 degrees and folds for storage — genuinely useful when you're packing 18 of them into a cabinet at the end of a period.
The audio side is straightforward. It's a wired 3.5 mm connection with a dynamic driver covering 20 Hz to 20,000 Hz, and the stated output sits between 95 and 101 decibels at maximum — clear for everyday listening without being harsh. There's no noise cancellation and no active anything; controls are media and volume via a remote on the cable. If your devices have a 3.5 mm socket — phones, computers, laptops, fitness equipment — you're covered.
Who should skip it? Anyone who wants wireless freedom, anyone who needs a single pair for personal critical listening, and anyone whose devices are USB-C or Bluetooth only. This is a set, not a solo upgrade.
The ZRUHIG 2-Pack goes in the opposite direction: two units, wireless, and shaped around comfort rather than volume. These are headband headphones — the speakers sit inside a fabric band that wraps your head, with ultra-thin drivers positioned over your ears instead of pushed into them. If you've ever woken up with sore ears from earbuds, that design choice is the whole point.
Bluetooth 5.4 handles pairing and connection, and the brand describes it as fast to pair and stable. The band closes with an adjustable magic tape strap, so it's a one-size-fits-all fit that you tighten or loosen yourself — useful if two different people are sharing the pair, which is likely given you get two. The fabric is breathable and moisture-wicking, which matters if you're wearing it all night or through a workout; it's also described as gentle on ears and hair, and specifically aimed at side sleepers who need pressure-free comfort.
Versatility is the other selling point. The same headband works for sleep, meditation, jogging, flights and yoga, and it pairs with a smartphone or tablet. It's Type-C rechargeable, and the fabric band is washable once you remove the speaker. There's a 1 year warranty listed, which is a reasonable safety net for a fabric-and-electronics hybrid.
Who should skip it? Anyone who needs a large matched set for a classroom or testing environment — two units won't cover a room. And anyone who wants a traditional over-ear cup design rather than a band.
• Best for equipping a group → Yunsailing 18. 18 individually wrapped units versus 2.
• Best for wireless freedom → ZRUHIG 2-Pack. Bluetooth 5.4 with no cable at all, against a fixed 3.5 mm wired jack.

• Best for school testing and computer labs → Yunsailing 18. Wired 3.5 mm reliability, no pairing, no charging, no battery to manage mid-session.
• Best for travel and light sport → ZRUHIG 2-Pack. Designed for flights, jogging and yoga, with a washable band.
• Best for repeated shared handling → Yunsailing 18. ABS shell, PVC cable and PU leather pads built to be used again and again.
• Best for two people who each want their own → ZRUHIG 2-Pack. Two complete headbands in one pack, each with its own fit adjustment.
• Best if your devices are USB-C or Bluetooth only → ZRUHIG 2-Pack. The Yunsailing set needs a 3.5 mm socket on every device.
For me it comes down to the shape of the job. If I were outfitting a classroom, a lab or a testing room, I'd buy the Yunsailing 18 — 18 wrapped, adjustable, wired over-ears with no pairing or charging to babysit is exactly what that environment needs, and the ABS/PVC build is suited to constant handling. If I wanted headphones for sleeping, travel or workouts — especially for two people — I'd buy the ZRUHIG 2-Pack, because the Bluetooth 5.4 headband with ultra-thin speakers and an adjustable magic tape fit solves a problem over-ear cups don't. In my opinion these two barely compete; they solve different problems, and the right answer depends entirely on whether you're buying for a crowd or for comfort. Check the current price on Amazon before you commit, since that's the one thing that can shift the math.
FAQ
how to adjust headphones
how to adjust headphones on iphone
For the Yunsailing 18, plug the 3.5 mm jack into a compatible device — note that many newer iPhones don't have a 3.5 mm socket, so you'd need an adapter. The ZRUHIG 2-Pack pairs over Bluetooth 5.4 instead, so on iPhone you connect it in the Bluetooth settings and adjust the fit with the magic tape band.
how to adjust headphones volume
On the Yunsailing 18, volume and media controls sit on the remote on the cable, and the set is rated for clear sound between 95 and 101 decibels at maximum. On the ZRUHIG 2-Pack, you adjust volume from your paired phone or tablet, since the headband itself doesn't list on-board volume controls.
how to adjust headphones sound
Neither product lists an equalizer or sound-tuning feature. The Yunsailing 18 gives you a wired dynamic driver covering 20 Hz to 20,000 Hz, so any sound adjustment happens on the connected device. The ZRUHIG 2-Pack is the same story — you'd adjust sound through your phone's or tablet's audio settings over Bluetooth.
