If you want wireless over-ear headphones with active noise cancellation for travel, choose ILOCKZONE LC30Pro; if you need a wired on-ear set for a classroom or group, choose YFSFQS 50. For swimming, neither is a swimming headphone: the LC30Pro is an over-ear Bluetooth headset, and the YFSFQS 50 is a wired on-ear model.
• ILOCKZONE LC30Pro’s biggest strength: wireless Bluetooth 5.4, active noise cancellation, and up to 100 hours of battery life. Main trade-off: it is an over-ear design, not a swimming-specific headset.
• YFSFQS 50’s biggest strength: a 50-pack of wired on-ear headphones with standard 3.5 mm connections, suited to shared school or learning use. Main trade-off: there is no Bluetooth, battery, or noise control.
• Choose ILOCKZONE LC30Pro for personal listening, travel, home, or office use when wireless features and long battery life matter.
• Choose YFSFQS 50 when you need many simple wired headphones for children, teens, or adults using devices with a 3.5 mm jack.
• For swimming: neither set is presented as water-resistant or designed for use in the pool, so I would not choose either specifically for that purpose.
The ILOCKZONE LC30Pro is a personal over-ear headset built around wireless listening. It uses Bluetooth 5.4 and has multipoint connection, so it can connect to two devices and switch between them. That arrangement makes sense for someone who moves between a tablet and phone, or who wants to listen on one device without ignoring calls on another. It also includes a 3.5 mm jack, giving it a wired connection option when Bluetooth is not the right fit.
Its standout practical feature is the stated battery life of up to 100 hours, with a two-hour charge time. The headset also supports active noise cancellation and uses 40 mm dynamic drivers. Those details point toward an individual listener who wants a versatile set for commutes, flights, office listening, or home use. The foldable design and 90-degree swiveling earcups are useful for packing and storage, while the memory-foam padding, faux-leather earcups, and adjustable headband are intended for longer listening sessions.
The trade-off is that this is still an over-ear headset, not a compact group-use set or a swimming product. Its listed wireless range is 10 meters, and its described connections are Bluetooth and a 3.5 mm jack; the data does not identify water protection. Who should skip it: skip the LC30Pro if you need headphones for swimming, or if your main requirement is a bulk set for a classroom rather than one personal headset.

The YFSFQS 50 is a set of 50 wired, on-ear headphones. Its most useful distinction is quantity: rather than buying one feature-rich headset for individual use, this product supplies a group with headphones that connect through a 3.5 mm jack. The listed age range includes children, teens, and adults, which makes the set relevant to schools, testing rooms, libraries, museums, and other shared listening settings.
The design is straightforward. These are on-ear headphones with a cable, not Bluetooth headphones, and the data lists no noise control. That simplicity can suit a setup where devices have compatible 3.5 mm ports and staff want a wired connection rather than charging and pairing a collection of individual wireless headsets. The set has a one-year warranty listed, but the product information does not specify battery life, because there is no battery feature described.
The trade-off is equally clear: YFSFQS 50 does not offer active noise cancellation, Bluetooth, or the personal listening features found on the LC30Pro. A 50-pack is suited to outfitting a group, not to someone shopping for one portable everyday headset. There is also no listed water-resistance information, so it should not be treated as suitable for a pool. Who should skip it: skip YFSFQS 50 if you want wireless listening, noise cancellation, or one headset with a long-lasting rechargeable battery.
• Best for Bluetooth listening → ILOCKZONE LC30Pro. It uses Bluetooth 5.4, while YFSFQS 50 is wired only.
• Best for connecting two devices → ILOCKZONE LC30Pro. Its multipoint feature is intended to switch between two connected devices.
• Best for long listening between charges → ILOCKZONE LC30Pro. Its stated battery life is up to 100 hours, though the YFSFQS 50 is wired and does not rely on a battery.
• Best for a classroom or group that needs many headphones → YFSFQS 50. It comes as a 50-pack, rather than as one personal headset.
• Best for devices with a 3.5 mm jack → either, depending on the use. Both list a 3.5 mm jack; the LC30Pro also supports Bluetooth, while YFSFQS 50 is wired.
• Best for active noise cancellation → ILOCKZONE LC30Pro. It lists active noise cancellation; YFSFQS 50 lists no noise control.
• Best for foldable, over-ear personal use → ILOCKZONE LC30Pro. Its earcups swivel and fold, and the design includes an adjustable headband.
• Best for swimming → neither. Neither product’s listed details describe water resistance or swimming use.
These differences matter more than the shared 3.5 mm connection. The LC30Pro is aimed at an individual who wants a set of wireless headphones with additional listening and travel features. YFSFQS 50 is aimed at someone equipping multiple listeners with basic wired headphones. They are not two versions of the same kind of product, and the right choice depends first on whether you are buying for one person or a group.
Buying Considerations
Start with the number of listeners. If you need one headset for your own tablet, phone, commute, or desk, the LC30Pro’s wireless connection, multipoint support, foldable form, and active noise cancellation are relevant. If you need to equip a classroom, testing room, or other group, the YFSFQS 50’s 50-unit quantity is the defining practical advantage. One is a personal listening product; the other is a bulk wired set.
Next, check the devices the headphones will connect to. Both products list a 3.5 mm jack, but only the LC30Pro also provides Bluetooth 5.4. YFSFQS 50 is wired, so it avoids the need to pair or charge a wireless headset, but the device needs a compatible jack. The LC30Pro offers more connection flexibility, though its wireless range is listed as 10 meters and its battery needs charging.
Consider fit and environment, too. The LC30Pro is over-ear, with memory-foam padding, a headband, and foldable, swiveling earcups. YFSFQS 50 is on-ear. Those are different wearing styles, and the product details do not provide a basis for claiming one will fit every listener better. Neither product lists water resistance. That is especially important if the intended use is swimming: the phrase best hi res sleep headphones for swimming combines needs that these listings do not establish. Neither product is described as a swimming headset or as a high-resolution sleep headphone, so I would look for a product whose specifications explicitly match those uses.
Finally, think about features you will actually use. For an individual who wants active noise cancellation, long stated battery life, and the option to use either Bluetooth or a cable, the LC30Pro has the more varied feature set. For a school or organization that needs 50 wired sets and does not require noise control or wireless pairing, YFSFQS 50 has the more suitable format. If purchase cost affects your decision, check the current price on Amazon; I would not infer which is the better value without comparing the current prices and considering whether you need one headset or a 50-pack.
I would choose the ILOCKZONE LC30Pro for personal listening because Bluetooth, multipoint connection, active noise cancellation, and up to 100 hours of stated battery life give it more flexibility for travel and daily use. I would choose YFSFQS 50 instead when the real need is a wired set for a group. For swimming, my recommendation is neither: the listed details do not establish that either product is suitable for water.
Neither is described as water-resistant or designed for swimming. The LC30Pro is an over-ear Bluetooth headset, while YFSFQS 50 is a wired on-ear set, so I would not select either specifically for pool use.
No Bluetooth connection is listed for YFSFQS 50. It is a wired headphone set with a 3.5 mm jack, so check that the devices you plan to use have a compatible connection.
Its multipoint feature is described as allowing it to connect to two devices and switch between them. It also supports Bluetooth 5.4 and has a 3.5 mm jack for a wired connection.
YFSFQS 50 is the more directly suited format if you need headphones for many students, since it is a 50-pack of wired on-ear headphones. The LC30Pro is a single personal headset with wireless and noise-cancellation features, rather than a bulk classroom set.
