• Yunsailing 30 biggest strength: 30 individually wrapped 3.5mm on-ear headsets in one set, ready to hand out and store in a computer lab, library or training room.
• Yunsailing 30 biggest trade-off: no microphone, no in-line volume control, and no per-unit flexibility — it's a fixed, all-at-once purchase aimed at groups, not solo buyers.
• KLOJIM L02 biggest strength: a rotatable noise-reducing boom mic plus in-line volume on the cable, so you can talk and adjust levels without touching your device.
• KLOJIM L02 biggest trade-off: one headset per purchase, no bulk option, and the mic needs a splitter on dual-port PCs (not included).
• Choose Yunsailing 30 if you're equipping a room full of shared workstations for ages 14+.
• Choose KLOJIM L02 if you're one person on calls, online classes or gaming who needs a mic and volume control.
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 is the detail that matters most in a shared environment: hand one to each user, wipe it down, bag it, store it. No untangling a pile, no guessing which unit belongs to whom. For a computer lab, library, training room or testing center, that individually wrapped format is the entire point.
On the audio side, it's straightforward: a standard 3.5 mm jack that plugs into laptops, desktops and tablets, an adjustable headband with soft ear cushions, and a 1.2 m (3.94 ft) PVC cable paired with a sturdy ABS shell. The cable length is worth noting — it's short enough to stay tidy at a desk station and long enough to reach a tower or a wall-mounted port without strain. The design is rated for users aged 14 and above, and the intended uses map cleanly onto that: digital lessons, reading programs, language practice, multimedia projects and group testing.
Who should buy it? Anyone buying headphones in quantity for a shared space — schools, labs, libraries, training departments — where the priority is durability, easy distribution and standardized gear across many seats. Who should skip it? A single buyer who needs to speak on calls. There's no microphone here, and no in-line volume either; you control levels from the device. The listing also notes volume control and touch control among its control methods, but for a wired 30-pack the practical reality is that you'll be setting volume on the laptop or tablet. If your day involves talking as much as listening, this is the wrong tool.
The KLOJIM L02 is the opposite shape of purchase: one headset, built around communication. The centerpiece is the rotatable noise-reducing microphone, which swings up to 120° so you can park it near your mouth for calls and swing it out of the way when you're just listening. In an open office, a dorm room or a house with background noise, that mic design is the difference between being understood and being asked to repeat yourself.
Comfort gets real attention too. The headband is extra-padded and adjustable, and the on-ear cushions use memory foam wrapped in protein leather — a combination that matters on long shifts or back-to-back classes, because it spreads pressure instead of pinching. Sizing is broad: kids aged 4+, teens and adults, which makes it a genuinely household-wide headset rather than an adult-only one. The frequency range is listed at 20 Hz–20 kHz with a dynamic driver, so it covers the full audible band for voice, music and game audio.
The controls are the practical selling point for office work. In-line volume lets you nudge levels up or down on the cable without alt-tabbing to a mixer or reaching for a device — useful in call centers, remote work and shared desks. The cable is reinforced and tangle-resistant, and the mic boom is flexible, which is what usually fails first on cheap headsets. Two caveats worth knowing before you buy: it's a single unit, not a pack, and if your PC has separate headphone and mic ports you'll need a splitter (not included) to use the microphone.
Side-by-Side: Which Should You Choose?
• Best for equipping a whole room → Yunsailing 30. 30 individually bagged headsets beat buying 30 singles, both for distribution and for storage.
• Best rechargeable headphones for office → neither, and that's the honest answer. Both are wired 3.5 mm headsets; there's no battery to manage and nothing to charge, which for a fixed desk station is a feature, not a limitation.
• Best usb c charging gaming headphones for office → neither. Both use a 3.5 mm jack, so plug them into a headphone port or a USB-C adapter rather than expecting a USB-C cable.
• Best touch control kids headset for office → KLOJIM L02, with a caveat. It's the one sized for kids 4+ through adults, but its controls are in-line and its touch control method is listed without any noise control, so treat "touch" as a minor labeling detail, not a headline feature.
• Best for long group testing sessions → Yunsailing 30. Adjustable headbands, soft cushions and a 1.2 m cable are tuned for seated, stationary use across many users.
• Best for noisy open offices → KLOJIM L02. The noise-reducing mic keeps your voice clear; note that neither headset lists active noise cancellation for what you hear.
• Best for a single user who also wants to listen to music → KLOJIM L02. Full 20 Hz–20 kHz range, memory foam cushions and a mic in one unit.
For office use, I'd buy the KLOJIM L02. In my opinion, the mic, the in-line volume and the memory foam cushions solve the three problems that actually come up in a workday — being heard, adjusting levels fast, and staying comfortable through a long shift. I'd choose the Yunsailing 30 only if my job were buying for a room rather than a person: 30 wrapped headsets for a lab, library or training space is a logistics win no single headset can match. One buys you a fleet; the other buys you a conversation. Work out which one you actually need, then check the current price on Amazon before committing.
Neither of these is positioned as a bare-minimum throwaway, and I won't quote prices here — check the current price on Amazon for both. As a rule, a bulk set spreads its cost across 30 units, so the per-headset figure for the Yunsailing 30 is far lower than buying 30 singles. The KLOJIM L02 is a single unit with a mic, so it costs more as a one-off.
You don't pair either of these. Both are wired headsets with a 3.5 mm jack — plug the connector into your laptop, desktop, tablet or phone and you're done. The Yunsailing 30's listing mentions Bluetooth among its connectivity fields, but its actual connection is the 3.5 mm wired jack, so treat it as a plug-in headset.
Start with fit: the KLOJIM L02's adjustable padded headband and memory foam cushions and the Yunsailing 30's adjustable headband with soft ear cushions both seal better when sized correctly, which tightens bass. Then set volume at the source — the Yunsailing 30 has no in-line control, so use your device, while the KLOJIM L02 lets you fine-tune on the cable. On a dual-port PC, use a splitter so the mic and audio channels aren't fighting over one jack.
For a group, the practical route is a bulk set like the Yunsailing 30 — 30 individually wrapped units meant for shared spaces, so you buy once instead of repeatedly. For one person, the KLOJIM L02 covers listening, talking and volume control in a single headset, which saves you buying a separate mic. Compare the current prices on Amazon for each, since bulk and single-unit math work out very differently depending on how many people you're equipping.
