If you want a larger class set with a standard 3.5 mm connection, choose Yunsailing 18; if you need USB-C headphones in five distinguishable colors, choose OYSLKJ 5. For audiophiles, neither is a high-end listening model; the practical choice is the one that fits your devices and listening routine.
Yunsailing 18 vs OYSLKJ 5 at a Glance
• Yunsailing 18’s strength: 18 individually wrapped, adjustable over-ear headphones with a 3.5 mm plug. Trade-off: wired connection and no USB-C plug.
• Yunsailing 18 fits classrooms, shared listening stations, and buyers who need a larger set.
• OYSLKJ 5 fits smaller groups using compatible USB-C devices who want to identify each person’s headphones by color.
Yunsailing 18 is the more practical fit when the main job is equipping a group. It comes with 18 headphones, each individually wrapped, so a teacher or organizer can distribute them as needed rather than manage one shared pair. That format can also make sense for school testing, learning centers, or other settings where multiple people need wired headphones at once.
The over-ear design, adjustable fit, soft ear pads, and PU leather earmuffs are aimed at everyday student use. The headphones have a 90-degree rotating and folding storage design, which gives the set a way to pack down for storage. Their cable is approximately 1.2 meters long, and the 3.5 mm plug works with compatible socket devices such as computers, laptops, phones, and fitness equipment. The listed sound range reaches 95–101 decibels; that describes the stated maximum sound level, not a promise of a particular listening experience.
The main limitation is connection type. A device needs a compatible 3.5 mm socket, so buyers should check their equipment before choosing this set. Skip Yunsailing 18 if your devices require USB-C headphones and do not have a compatible 3.5 mm connection.

For someone searching for the best comfortable earbuds for audiophiles, these are not earbuds: they are wired, adjustable over-ear headphones designed around group use. I’d consider them for straightforward classroom listening, not for a dedicated audiophile setup. Their strongest case is quantity and familiar 3.5 mm connectivity, rather than advanced audio features.
OYSLKJ 5 is built around a different need: a small group with compatible USB-C devices. The five wired headphones connect through USB Type-C, which can be convenient for Chromebooks, tablets, phones, and laptops that support that connection. Since the sheet specifies USB-C rather than a 3.5 mm jack, the device connection is the first thing I would confirm before buying.
That focus is both a useful boundary and a trade-off. A buyer who needs a microphone should look elsewhere, and a USB-C plug does not guarantee compatibility with every device: the device still needs to support headphones through USB-C. Skip OYSLKJ 5 if you need a larger class set, a microphone, or a specified 3.5 mm connection.
For shoppers looking for the best open ear earbuds for audiophiles, this is not an open-ear design; it is an on-ear wired headphone set. It may suit focused listening for schoolwork, but the supplied features do not point to specialized audiophile tuning or an open-ear listening experience. Its strongest advantage is direct USB-C connectivity combined with five easily distinguished colors.
• Need headphones for a larger group? → Yunsailing 18. Its package contains 18 individually wrapped headphones, compared with five in the OYSLKJ set.
• Need a USB-C connection? → OYSLKJ 5. It connects through USB Type-C, provided the device supports headphone audio through that port.
• Need a 3.5 mm plug? → Yunsailing 18. Its plug is specified for compatible 3.5 mm socket devices.
• Want individual color choices? → OYSLKJ 5. The set comes in five listed colors, which can help students tell their headphones apart.
• Prefer over-ear placement? → Yunsailing 18. Its listed design is over-ear; OYSLKJ 5 is on-ear.
• Need a microphone for speaking? → Neither is a clear fit based on the listed details. OYSLKJ 5 specifically has no microphone, and no microphone is specified for Yunsailing 18.
• Need headphones that fold for storage? → Yunsailing 18. Its design includes 90-degree rotating and folding storage.
• Choosing for audiophile listening? → Match the connection and fit first. Neither product’s listed features establish specialized audiophile performance, so I would not choose either on that promise alone.
My Verdict
I’d choose Yunsailing 18 for a classroom or shared listening setup because 18 individually wrapped, adjustable headphones make it the more useful group option. Its 3.5 mm plug also suits devices with the corresponding socket.
Before choosing, count the people who will use the set and check the ports on the devices. Those two details decide much of this comparison. Yunsailing 18 provides more headphones but relies on a 3.5 mm socket. OYSLKJ 5 offers USB-C, but its devices must support headphone audio through that port, and the set includes fewer units.
Next, think about fit and storage. Yunsailing 18 is over-ear and has a folding, rotating design, while OYSLKJ 5 is on-ear with an adjustable headband and soft cushions. These are different wearing styles, not interchangeable descriptions. If students need to sort out their own equipment, OYSLKJ 5’s five colors offer a clear organizing cue. If the priority is distributing individually wrapped pairs to a larger group, Yunsailing 18 is the more direct match.
Finally, consider what “listening” means in your setting. OYSLKJ 5 has no microphone, so its stated use is listening to lessons and audio content rather than participating by voice. Neither product sheet identifies noise control, wireless use, or audiophile-specific features. For a buyer comparing the best sweat resistant earbuds for audiophiles, neither set is described as sweat-resistant earbuds; both are wired headphone products, and I would not assume a sweat-resistance feature that is not listed. If you are weighing overall value, compare the current price on Amazon using the page’s price button, then judge it against the number of headphones and the connection your devices actually support.
Yunsailing 18 includes 18 individually wrapped headphones, making it the more suitable of the two for a larger class set. OYSLKJ 5 may suit a smaller group that needs USB-C headphones.
Does OYSLKJ 5 work with any USB-C device?
It has a 3.5 mm plug and is described for devices with a compatible 3.5 mm socket. Check the device’s ports before ordering, especially if it uses USB-C instead.
Neither data sheet specifies audiophile tuning, noise control, or other specialized listening features. I would choose between them based on group size, fit, and device connection, not an assumption of audiophile-grade sound.
