• Yunsailing 10 — biggest strength: a 10-piece bulk set of corded on-ear headsets, each individually wrapped in a sealed OPP bag, so you can hand them out, store them and rotate them between users without untangling a shared pile.
• Yunsailing 10 — biggest trade-off: it's built for groups of listeners, not for one person who wants a pocketable pair of earbuds with a microphone; there's no inline remote and no mic listed.
• CREHAO 2 — biggest strength: a two-pack of wired in-ear earbuds with a Lightning connector, a built-in microphone and a push-button controller for calls and playback — aimed squarely at iPhone users.
• CREHAO 2 — biggest trade-off: compatibility is narrow by design. If your device doesn't use a Lightning connector, this set isn't the one for you, and there's no volume dial or inline remote system beyond the button controller.
• Who each pick is for: Yunsailing 10 for schools, libraries, labs and anyone equipping many listeners at once. CREHAO 2 for an individual iPhone owner who wants a spare wired set with a mic.
The Yunsailing 10 is a bulk pack first and a headphone second. You're getting ten corded over-ear headsets, each sealed in its own OPP bag. That detail matters more than it sounds. In a computer lab, a library checkout desk or a training room, the messy part of headphones is never the audio — it's distribution and hygiene. Individually bagged units let you hand one to each learner, label them, store them by group and swap them between sessions without a bin of tangled cables.
The build is ABS plastic with a flexible 1.2 m (3.94 ft) PVC cable. That cable length is a deliberate choice: it's long enough to reach from a desktop tower or a laptop on a desk to a seated listener, and short enough that it doesn't pool on the floor where it gets rolled over by chairs. The adjustable headband and soft cushioned ear pads are there for extended wear — the kind of 40-minute online lesson or assessment block where a fixed-size headset starts to pinch. Yunsailing lists the intended audience as ages 14 and up, handling daily listening tasks like online lessons, reading programs, language practice and multimedia activities.
The 3.5 mm jack is the other reason this set works in shared environments. Laptops, desktops, tablets and most audio-enabled classroom devices still take a standard 3.5 mm plug, so one purchase covers a mixed fleet of machines instead of locking you into one platform. Frequency range is listed at 20 Hz to 20,000 Hz, which is the full audible band and entirely normal for this category. Noise control is passive, meaning the on-ear cushions physically block some surrounding sound rather than using electronics — which is exactly what you want in a room full of people, since there's no battery to charge and nothing to pair.
Who should skip it: a single user who wants earbuds for a phone, wants a microphone for calls, or wants something that fits in a pocket. This is a group-supply product, and judging it as a personal audio purchase misses the point.
CREHAO 2: Who It's For
The CREHAO 2 is the opposite kind of product: a two-pack of wired in-ear earbuds made specifically for Lightning-connector iPhones. The compatibility list is explicit — iPhone 14/14 Pro/14 Pro Max, 13 series including 13 Mini, 12 Mini, 12 Pro Max, SE, 11 Pro Max, 11 Pro, XS Max, X, XR, 8/8 Plus, 7 Plus and 7, across all iOS systems. If you own one of those phones, this is a plug-and-play set. If you don't, stop reading here, because the Lightning connector is the whole premise.
The feature that separates it from a bare-bones earbud is the inline controller. There's a built-in microphone and a multifunctional button: answer or end a call, play or pause, skip tracks, all without pulling the phone out of your pocket. For anyone who takes calls on a walk, listens to podcasts on a commute, or wants a wired backup set for the day the wireless earbuds die, that button is the reason to pick these.
On sound, CREHAO describes engineered drivers intended to maximize output and minimize loss, with what it calls enhanced bass and a natural, clear stereo presentation. The listed impedance is 80 ohm, which is on the higher side for earbuds and suggests they're designed to be driven by a phone's own output rather than a dedicated amp — normal for this category. Noise control is listed as adaptive, and the enclosure is in-ear, so the silicone tip seals the ear canal and physically reduces outside noise. You also get an 18-month warranty, which is a longer coverage window than many accessories in this tier offer.
Who should buy it: an iPhone owner who wants a cheap, replaceable wired set with a mic for calls, or someone who wants two pairs — one for the bag, one for the desk.
Who should skip it: Android users, anyone with a USB-C phone, and anyone who prefers over-ear fit for long listening sessions. And if you need headphones for a classroom of thirty, buying these two at a time makes no sense.
• Best for equipping a group → Yunsailing 10. Ten individually bagged headsets beats any two-pack when you're the person responsible for a room full of learners.
• Best for a single iPhone user → CREHAO 2. Lightning connector, built-in mic, inline button — it's designed around one phone and one person.
• Best for hands-free calls → CREHAO 2. The Yunsailing 10 has no microphone listed, so it's a listening-only headset.
• Best for wired compatibility with laptops and desktops → Yunsailing 10. The standard 3.5 mm plug fits the widest range of shared machines.
• Best for storage and hand-out logistics → Yunsailing 10. Sealed OPP bags per unit are a real advantage in libraries, labs and testing centers.
• Best for a spare set you can lose without caring → CREHAO 2. Two pairs in the box means one can live in a bag and one at home.
• Best for long wear sessions → Yunsailing 10. Adjustable headband plus cushioned on-ear pads are built for extended computer use; in-ear buds tend to fatigue some listeners faster.
• Best for portability → CREHAO 2. In-ear earbuds with a short cable disappear into a pocket; a ten-pack of on-ear headsets does not.
In my opinion, these two products aren't really competing — they solve different problems, and the "better" one depends entirely on who's buying. If I were outfitting a classroom, lab or training program, I'd buy the Yunsailing 10 without hesitating: ten bagged headsets, a standard 3.5 mm plug, adjustable fit and an ABS shell built for repeated handling is exactly the spec that survives a shared environment. If I were buying for myself and I carry an iPhone with a Lightning port, I'd take the CREHAO 2 — the mic and inline button are things the Yunsailing set simply doesn't have. For a group buyer, the Yunsailing 10 is my pick. For a personal iPhone user, it's the CREHAO 2.
how to wired headphones work
A wired headphone carries the audio signal from your device down a cable to drivers inside the ear cups or earbud tips, which convert the electrical signal into sound. Because the cable also supplies the connection, there's no battery and no pairing step — you plug in and listen. Both sets here work that way; the Yunsailing 10 uses a 3.5 mm jack, and the CREHAO 2 uses a Lightning connector.
how to use wired headphones with iphone
Plug the connector into your iPhone's port and the phone routes audio through the headset automatically. The CREHAO 2 is built for this with a Lightning connector and lists compatibility across iPhone 14, 13, 12, 11, XS Max, X, XR, 8/8 Plus, 7 Plus and 7, plus all iOS systems, with a built-in mic and button for calls and playback. The Yunsailing 10 uses a 3.5 mm plug, so it needs a compatible jack or adapter rather than plugging straight into a Lightning port.
how to fix wired headphones no sound
Start with the simple checks: make sure the plug is fully seated, try the headphones on a second device, and inspect the cable and connector for visible damage or debris in the port. If one device works and another doesn't, the problem is the port or a compatibility mismatch rather than the headset. Also confirm the device's audio output is set to the wired connection instead of a wireless one.

If you're asking how to actually use them, it's the least complicated audio setup there is: plug the cable into your device, put the headset on, and adjust volume with the device controls. The CREHAO 2 adds an inline button for answering calls and controlling playback; the Yunsailing 10 is a straight listening headset with an adjustable headband and cushioned pads. No charging, no pairing, no app.
