If you want open-ear listening that helps a child stay aware of their surroundings in a library, choose iClever OWS01; if you need a featherlight in-ear design with a charging case for study sessions, choose Jiawu Earbuds Featherlight Design. For a library setting, the key difference is whether you want an open-ear fit or earbuds that sit in the ear.
• iClever OWS01 strength: Open-ear air-conduction design, a stated 74 and 85 dBA volume limit, and a flexible, lightweight build. Trade-off: It is designed for kids, and the listed battery information gives charging time but not listening time.
• Jiawu strength: Slim in-ear earbuds, ENC microphones for clearer calls in background noise, and a case with a stated 600mAh capacity. Trade-off: The sheet gives standby time rather than playback time, and provides no battery-life figure for listening.
• Choose iClever OWS01 if a child needs to hear more of the surrounding environment while listening.
• Choose Jiawu if you prefer an in-ear fit and want earbuds with a charging case for study or work.
• For a quiet library, either design has a trade-off: open-ear listening leaves sound less isolated, while in-ear earbuds sit inside the ear and may feel less suitable to someone who dislikes that fit.
The iClever OWS01 is a kids’ Bluetooth 5.4 open-ear headphone. Its air-conduction design does not place an earpiece inside the ear canal, which may suit a child who finds conventional earbuds uncomfortable or whose caregiver wants the child to remain more aware of nearby sounds. The listed volume limits are 74 and 85 dBA, and the controls are physical buttons intended to be simple to use.
Its flexible back-hanging section uses memory steel and is described as bendable through 360 degrees without deformation. The headphones weigh 0.8 ounces, use soft TPE, and have a three-point pressure-dispersion design. Those are concrete reasons to consider it for a child who may wear headphones during a school day, on a trip, or while moving between activities. Bluetooth 5.4 supports connections to devices such as phones, tablets, laptops, PCs, and smartwatches.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
For library use, the open-ear design is the defining compromise. It can help the wearer stay more aware of the room, but it does not create the same in-ear fit as the Jiawu earbuds. The listed 14.2 mm dynamic drivers and 20 Hz–20,000 Hz frequency range describe audio capability, not how much sound is kept from other people. I would skip this model if you want an adult-oriented in-ear option or if the priority is a stated listening-time figure: the supplied information lists a 1.5-hour charging time, but no playback duration.
Jiawu Earbuds Featherlight Design: Who It's For
Jiawu’s earbuds take the opposite approach: they are an in-ear design, with a stated thickness of 6 mm and maximum width of 8 mm. The product information describes them as lightweight and slim, aimed at extended work or study sessions. If you specifically want earphones for library use that sit in the ear rather than hang around it, this shape is the main reason to consider Jiawu.
The listed wireless specification is 5.4, and the charging case has a stated 600mAh capacity. Each earphone is listed with a 45mAh built-in battery. The sheet also gives a one-hour charging time and 120 hours of standby time. Those numbers are useful context, but standby time is not the same as continuous audio playback; it should not be read as 120 hours of listening.
Jiawu also lists ENC noise-cancelling technology using integrated microphones, described as helping make a caller’s voice clearer in noisy surroundings. That is a call-focused feature, not evidence that the earbuds block library noise for the wearer. I would consider them if an in-ear fit, a charging case, and calls matter more than an open design. I would hesitate if you need documented playback endurance, because none is specified, or if you want a non-in-ear style for comfort or awareness.
• Best for a child who needs awareness of nearby sounds → iClever OWS01. Its open-ear design leaves the ear canal unoccupied; Jiawu is explicitly in-ear.
• Best for an in-ear, slim profile → Jiawu. Its stated dimensions are 6 mm thick and up to 8 mm wide.
• Best for a stated listening-volume limit → iClever OWS01. The product sheet lists 74 and 85 dBA limits, while Jiawu’s sheet does not give a volume-limit figure.
• Best for a flexible, lightweight kids’ headphone → iClever OWS01. It weighs 0.8 ounces and has a memory-steel back section described as bendable through 360 degrees.
• Best for call-focused noise handling → Jiawu. Its ENC microphone feature is described as helping voices come through clearly amid background noise.
• Best for documented case and earbud battery capacities → Jiawu. The sheet specifies a 600mAh charging case and 45mAh per earbud, but not listening duration.
• Best for library awareness rather than a sealed in-ear fit → iClever OWS01. Its open-ear construction is the more natural match for someone who wants to remain conscious of the room.
• Best long battery life Bluetooth headset for library? Neither can be confirmed from the supplied figures. Jiawu lists 120 hours of standby, not playback; iClever lists charging time but no listening-time figure.
Neither product should be mistaken for a proven solution to every library distraction. Jiawu’s ENC feature concerns microphone performance during calls; the provided details do not say it reduces noise reaching the wearer’s ears. The iClever OWS01’s open design may be appealing when awareness matters, but open-ear construction is not the same as sound isolation. If your library requires quiet listening, keep volume and sound leakage in mind whichever design you choose.
The phrase “sweatproof headphones for library” also needs a careful read. The iClever is described for sports and outdoor settings, but the supplied information does not state a water-resistance or sweatproof rating. Jiawu’s sheet likewise gives no such rating. I would not choose either on the basis of an assumed sweatproof claim.
I would choose the iClever OWS01 for a child using headphones in a library, because its open-ear design, stated volume limits, and flexible lightweight build address awareness and kid-focused use directly. Jiawu is the better fit if an in-ear shape, a slim profile, and call-focused ENC matter more. For the library, my preference is the iClever—not because it promises isolation, but because its design better suits listening while staying aware of the room.
For a child who should remain more aware of nearby sounds, I’d lean toward the open-ear iClever OWS01. Jiawu is the choice if you prefer an in-ear fit; its ENC feature is described for calls, not for blocking noise during study.
The supplied details do not establish that. Jiawu lists 120 hours of standby and battery capacities, but no playback duration. iClever lists a 1.5-hour charging time, but no listening-time figure.
The listed ENC technology uses microphones to help make the wearer’s voice clearer on calls in background noise. The product information does not say it provides active noise cancellation for listening or reduces library sounds around the wearer.
The supplied details do not include a sweatproof or water-resistance rating for either product. iClever is described for sports and outdoor use, but that alone does not establish sweat protection.
