How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one pair of comfortable, feature-rich wireless headphones with active noise cancelling and app control, choose Sony WH-CH720; if you need a large batch of simple wired headsets to hand out to a group, choose Yunsailing 30.
• Sony WH-CH720 — biggest strength: Active Noise Cancelling, Bluetooth 5.2 wireless freedom, app-based EQ, and up to 35 hours of battery life in a lightweight over-ear design.
• Sony WH-CH720 — biggest trade-off: It's a single pair of headphones built for one owner, so it doesn't fit a classroom or lab that needs to equip many people at once.
• Yunsailing 30 — biggest strength: It's a 30-pack of individually wrapped wired headsets, ready to distribute, store and rotate across groups of users.
• Yunsailing 30 — biggest trade-off: It's a basic wired 3.5 mm design with sound isolation only — no active noise cancelling, no Bluetooth, no app features, and no battery.
• Who each pick is for: Sony WH-CH720 is for one person who wants premium daily listening; Yunsailing 30 is for a school, library, computer lab or training program that needs to equip a whole room.
The Sony WH-CH720 is over-ear headphone built around the idea of one person wearing it for hours. The Integrated Processor V1 and Digital Sound Enhancement Engine work together to produce balanced tuning with clear vocals, and you can fine-tune the sound yourself through the EQ settings in the Sony | Headphones Connect app. If you're the kind of listener who fiddles with sound until it fits your taste, that app control is a genuine advantage over a plain wired headset.
Noise cancelling is where it separates itself. Dual Noise Sensor technology and the V1 processor drive the active noise cancelling, and the app lets you adjust ambient sound across 20 different levels — which matters when you're moving between a quiet desk and a noisy commute. It also supports Multipoint Connection so it can stay paired to two devices at once, plus Swift Pair and Fast Pair for quick setup. On the call side, Precise Voice Pickup Technology, a wind noise reduction structure and beamforming mics are aimed at making your voice clearer on the other end.
Who should skip it? Anyone buying for a group. If you need 30 headsets for a lab, a 30-pack of wired units makes far more sense than 30 individual Bluetooth headphones. Also skip it if you specifically want a purely wired, zero-maintenance device — the Sony's strengths are exactly the wireless and app-based features a wired-only user doesn't need.
Yunsailing 30: Who It's For
The Yunsailing 30 is a completely different product solving a completely different problem. It's a bulk set of 30 wired over-ear headsets in Macaron Color, each one individually wrapped in a sealed OPP bag. That packaging detail is the whole story: it's designed for clean, convenient handout, storage and organization, which is exactly what you need when headsets rotate between users, groups or sessions.
The build is aimed at high-traffic environments. The shell is ABS, the cable is flexible PVC at roughly 1.2 m (3.94 ft), and that length works well with desk setups, shared devices and study stations. The adjustable headband and soft cushioned ear pads are there to keep wear comfortable through long computer sessions, focused listening, online lessons and testing. Audio comes from a dynamic driver with a 20 Hz – 20,000 Hz frequency range, and noise control is sound isolation rather than active cancelling.
Connectivity is the simple part: a standard 3.5 mm jack, wired, compatible with laptops, desktops, tablets and other audio-enabled devices commonly used in learning and training setups. Yunsailing positions these for people aged 14 and above doing daily listening tasks — online lessons, reading programs, language practice, multimedia activities and assessments — in computer labs, libraries and training environments.
So who should buy it? Whoever is responsible for equipping a room. A teacher, lab manager, librarian or training coordinator who needs 30 working headsets on day one, without pairing, charging or app setup. Who should skip it? Anyone who wants active noise cancelling, wireless freedom, app EQ or a single premium pair for personal listening. These are practical tools, not personal audio gear — and that's the point.
• Best for one person's daily listening → Sony WH-CH720. Wireless Bluetooth 5.2, app EQ and 360 Reality Audio support make it a personal headphone.
• Best for equipping a group → Yunsailing 30. Thirty individually wrapped wired headsets, ready to distribute and rotate.
• Best for noise cancelling → Sony WH-CH720. Active Noise Cancelling with 20 adjustable ambient sound levels versus sound isolation only on the Yunsailing.
• Best for zero setup and zero charging → Yunsailing 30. Wired 3.5 mm, no battery, no pairing, no app.
• Best for long battery life → Sony WH-CH720. Up to 35 hours with noise cancelling on, roughly 3 hours to charge.
• Best for shared desks and study stations → Yunsailing 30. The 1.2 m flexible PVC cable and ABS shell are built for frequent handling.
• Best for clearer calls → Sony WH-CH720. Beamforming mics, Precise Voice Pickup Technology and a wind noise reduction structure.
• Best for large-scale learning, testing and training → Yunsailing 30. It's explicitly designed for labs, libraries, lessons and assessments.
Notice that these two barely compete. One is a single premium wireless headphone; the other is classroom infrastructure. The "which is better" question really means "which is better for what you're actually doing."
For most people reading a headphone comparison, I'd buy the Sony WH-CH720. In my opinion, active noise cancelling, Bluetooth 5.2, app-based EQ, multipoint connection, clearer call tech and up to 35 hours of battery life cover almost everything a single listener needs, and the lightweight over-ear design is built for long sessions.
The Yunsailing 30 only wins if your job is handing out headsets to a group. If you're buying for a classroom, lab or training program, buy the Yunsailing 30 — and don't overthink it.

I don't quote prices here, because they change. The real deciding factor is quantity and use: one premium wireless headphone versus 30 basic wired headsets. Check the current price on Amazon for each and compare against how many people you actually need to equip.
