How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a bulk classroom-ready set of wired headphones you can hand out, store and replace one by one, choose Yunsailing 30; if you need a two-pack of washable, wireless sleep-and-sport headbands for side sleepers and workouts, choose Perytong 2.
• Yunsailing 30 – biggest strength: 30 individually wrapped over-ear headsets with a 3.5 mm plug, an adjustable headband and a flexible 1.2 m cable, built for group learning, labs, libraries and testing rooms.
• Yunsailing 30 – biggest trade-off: It's a wired, one-device-at-a-time headset with no per-user hygiene routine beyond wiping it down, so it suits shared stations rather than personal all-night use.
• Perytong 2 – biggest strength: Two Bluetooth 5.4 headbands that double as sleep masks and sport headbands, with 14-hour playtime, removable washable speaker pods and 43 ft of wireless range.
• Perytong 2 – biggest trade-off: There's no audio jack at all, so anything without Bluetooth is out, and the 40 mm speakers sit flat against your ears rather than around them.
• Pick Yunsailing 30 if you're outfitting a classroom, computer lab, library or training program with dozens of users.
• Pick Perytong 2 if you're a side sleeper, jogger, yoga-goer or traveler who wants private audio without earbuds pressing into your ears.
The Yunsailing 30 is a logistics product as much as an audio product. You get 30 over-ear headsets, each sealed in its own OPP bag, which sounds like a small detail until you've tried to hand out gear to a room of 30 people. Individually wrapped units mean you can distribute, collect and store them without untangling a pile of loose cables, and you can replace a single failed unit instead of the whole set. For anyone running rotating groups — a testing center, a language lab, a library checkout desk — that's the whole point.
On the spec sheet, the design is deliberately plain and durable: an ABS shell, round over-ear cups, a dynamic driver covering 20Hz–20,000Hz, and a flexible 1.2 m (3.94 ft) PVC cable that's long enough for a desk setup without becoming a trip hazard. The adjustable headband plus soft cushioned pads are there for extended wear, which matters when a student is sitting through a full online lesson or an assessment block. The 3.5 mm jack is the connector you'll find on essentially every laptop, desktop and tablet in a school or office environment.
Perytong 2: Who It's For
The Perytong 2 is a completely different animal. It's a two-pack of fabric headbands with ultra-thin 40 mm dynamic speakers sewn into the band, and it does three jobs at once: sleep headphones, sport headband and light-blocking sleep mask. Because the speakers are flat, side sleepers can lie on their ear without a hard plastic shell digging in — that's the specific problem this design solves, and it's why the product exists at all.
The two-pack is the second smart decision. Two headbands mean two people can connect to two separate phones and listen to completely different content in the same bed or on the same trip, and each person keeps their own band. The material is spandex, nylon and elastic, breathable and sweat-absorbent, and the speaker pods come out so the fabric can go in the washing machine. After a sweaty run or a week of nightly wear, that's the difference between gear you keep using and gear you quietly stop using.
Technically, it runs Bluetooth 5.4 with a stated range of 43 feet, charges in about an hour, and delivers up to 14 hours of playtime — enough for a full night of sleep sounds plus the next day's workout. Controls are touch-based on the band, and there's a built-in mic for hands-free calls. Noise control is listed as sound isolation rather than active cancellation, so expect it to mute the room somewhat, not erase it.
Who should buy it: insomniacs, side sleepers, couples and roommates, joggers, yoga practitioners and travelers who want audio without earbuds in their ear canals. Who should skip it: anyone who needs to plug into a laptop, testing terminal or airline seat jack — there is no jack here — and anyone who wants the fuller, more enclosed feel of traditional over-ear cups.
Side-by-Side: Which Should You Choose?
• Best for classrooms, labs and testing rooms → Yunsailing 30. 30 wrapped units, 3.5 mm plug, plug-and-play with zero pairing.
• Best for sleep and side sleeping → Perytong 2. Flat 40 mm speakers and a fabric band you can lie on.
• Best for shared hygiene → Perytong 2. Two separate bands, each washable, so nobody shares earpieces.
• Best for device compatibility breadth → Yunsailing 30. The 3.5 mm jack works with anything that has a headphone port; Bluetooth-only gear can't.
• Best for freedom of movement → Perytong 2. Wireless with a 43 ft range, versus a fixed 1.2 m cable.
• Best for long uninterrupted sessions → Perytong 2 on paper. Up to 14 hours per charge, though it needs recharging; the wired Yunsailing never runs out.
• Best for one-to-many deployment → Yunsailing 30. Bulk packaging is the feature; two headbands don't outfit a room.
In my opinion, these two don't really compete — they solve opposite problems, and the right answer is whichever problem you actually have. If you're buying for an institution or a shared learning space, I'd take the Yunsailing 30 without hesitation: 30 sealed units, a 3.5 mm plug that works with everything already on the desks, and a build aimed at being handed out and collected daily. If you're buying for yourself or a partner to sleep, run and travel with, I'd take the Perytong 2 — the washable fabric, the two-band setup and the flat speakers for side sleepers are the reasons it exists, and no wired classroom headset can replace that. Buy for the room, not for the spec sheet.
how to fix headband on headphones
Start by checking whether the headband is adjustable or fixed. The Yunsailing 30 has an adjustable headband specifically so each user can size it — slide the extenders to fit rather than bending the band, which is what usually causes cracking on ABS shells. The Perytong 2 has no rigid headband at all; its band is stretchy spandex/nylon fabric, so there's nothing to adjust or snap. If a rigid band is physically broken, it generally isn't a user-repairable part.
Are these headphones wired or wireless?
The Perytong 2, clearly. Its 40 mm speakers are built thin enough to lie on, the fabric is sweat-absorbent and machine washable with the pods removed, and touch controls let you skip tracks mid-run. The Yunsailing 30 is an over-ear ABS headset with a cable — fine at a desk, uncomfortable against a pillow, and not intended for sweat.
Only with the Perytong 2. It charges in about an hour and runs up to 14 hours, so a night of sleep audio plus a workout fits comfortably, but it does need charging. The Yunsailing 30 has no battery to manage at all — it draws nothing and works the instant it's plugged in, which is exactly why it suits shared stations. Check the current price on Amazon before deciding, since value depends on how many units you actually need.
