Cillso is my pick among yisen earbuds for library study: its in-ear design, up to 40 hours with the case, and touch controls make for a capable everyday wireless option.
Choose Kanayu instead if you need a bulk supply of simple wired earbuds for a classroom or shared library devices.
• Cillso Earbuds — best for wireless study sessions; pick this if you want Bluetooth 5.4, touch controls, and up to 40 hours of total playback with the case.
• Cillso Earbuds — best for a lighter semi-in-ear feel; pick this if you prefer its 3.5-gram earbuds and LED battery display.
• WXQZXO 2026 — best for quiet routines that continue into bedtime; pick this if sleep mode, white noise, and sleep tracking suit your needs.
• Xuhal 200 — best for shared wired listening; pick this if you need a 200-piece supply with 3.5 mm plugs.
• Kanayu 100 — best for classroom or library distribution; pick this if individually bagged, 3.5 mm wired earbuds are useful for your group.
This first Cillso option is a conventional in-ear wireless pair, identified as model H97. Bluetooth 5.4 and a charging case make it a practical choice for someone who wants to bring one personal set to the library and use it with a compatible phone, tablet, or laptop. Its listed range is 15 meters, though a study setup usually keeps the connected device close by.
The everyday draw is a combination of touch controls and battery information on the case’s LED display. A single charge is listed for up to eight hours of playback, with up to 40 hours total when the case is included. The case recharges through USB-C, and the stated charging time is 1.5 hours. Those figures describe useful flexibility for long study days, while the display makes it easier to see whether the case needs attention before heading out.
The earbuds use 14.2 mm drivers, and the listing describes an in-ear fit with an airflow structure intended to reduce pressure. ENC is specified for calls, which may help when speaking in a noisier setting, but it is not a claim that the earbuds will make a library quieter. The listed noise control is passive, so fit and ear-tip isolation matter more than expecting electronic cancellation for study.
The trade-off is that an in-ear fit will not suit everyone, especially someone who dislikes having an earbud sit in the ear canal. Touch controls also require a light tap rather than a physical button. In my opinion, this is the strongest all-purpose pick here for library listening if you want wireless convenience, a substantial stated case battery total, and compact controls.

The second Cillso entry is also an H97 in-ear wireless model, but its published details emphasize a semi-in-ear ergonomic design and a lighter 3.5-gram earbud weight. That makes it worth considering if you want a small personal pair for reading, commuting to the library, or switching between a phone and laptop. Its charging case has an LED display, and Bluetooth 5.4 is listed for wireless connection.
Like the first Cillso, it offers up to eight hours of playback from the earbuds and up to 40 hours with the case. USB-C charging is specified, with a 1.5-hour case charge time. Touch controls cover common actions such as playback, calls, and track changes, while ENC is included for calls. The listing also describes IPX7 protection against sweat, rain, and splashes, which is relevant for carrying the earbuds through changing weather—not a reason to use them in water.
The sound specification names 13 mm drivers in the feature description, while the product information lists a 14.2 mm driver. Because those details do not agree, I would not make driver size a deciding factor between the two Cillso listings. Both are described as offering a 20 Hz to 20 kHz range, and the second listing notes AAC and SBC codecs.
Its main trade-off is a mismatch between some published specifications and the fit description, so buyers should focus on the features that are clear: wireless use, touch control, an LED case display, and the stated battery figures. In my opinion, it is a reasonable alternative if the semi-in-ear description appeals to you more than a conventional in-ear fit. Neither listing establishes that it is an open-ear design, so it is not the right match if you specifically want touch control open ear earbuds for library use.
WXQZXO’s Z500 is built around sleep-oriented features rather than a straightforward study-first design. It is a small in-ear wireless set with Bluetooth connectivity, touch controls, and a companion app. Its most distinctive tools are sleep mode, scheduled playback, white noise, and sleep tracking. Someone who studies late and then wants a separate audio routine for winding down may find that combination more relevant than standard music-focused controls.
Sleep mode is described as muting voice assistants, call ringtones, and system notifications, while the app provides built-in white noise. The feature description also says playback can pause when sleep is detected. The app is intended to show sleep-related information such as sleep stages, position, and duration. These are specialized functions, and they depend on using the earbuds with the app; they are not necessary for someone who simply needs audio for a lecture or reading session.
The product is listed with Bluetooth 6.0 and up to six to eight hours of use per charge, with up to 48 hours including the case. The product information separately gives an average battery life of six hours, so I would treat the longer figure as the stated maximum rather than assume that every use will reach it. Each earbud is described as about three grams, and the design is presented as comfortable for side sleepers.
The trade-off is that its sleep tools and app add complexity if your only aim is quiet library listening. It is also still an in-ear product with passive noise control, not a purpose-made open-ear option. I would choose it for sleep features first, then consider library use as a secondary role.
Xuhal 200 is a bulk set of wired earbuds rather than a personal wireless pair. The package contains 200 earphones with 3.5 mm plugs, making it a practical format for a school, program, or shared listening station that needs many sets at once. The earbuds have rounded tips, and the listed cable length is about one meter.
For library use, the wired connection has one straightforward advantage: there is no Bluetooth pairing step or charging case to manage. A 3.5 mm plug can work with devices that have a compatible headphone jack. That limitation matters, though, because many phones and laptops may require a suitable jack or adapter. The product information gives a 20 Hz to 20,000 Hz frequency range and lists sound isolation as its noise-control type.
The set is described as lightweight, with an anti-tangle design and several colors. Those details may help when distributing earbuds across a classroom or shared workspace. But this is a group supply, not the natural choice for an individual looking for a durable daily wireless companion. The wired format also ties the listener to the device.
I would consider Xuhal when the need is quantity and a 3.5 mm connection, not when the priority is wireless convenience or a feature-rich personal listening experience. It is not a clip-on model, and the available details do not describe an open-ear design. That makes it a poor match for shoppers specifically seeking bluetooth clip on earbuds for library use.
Kanayu 100 is another bulk wired option, with 100 light-blue earbuds supplied for classroom or group use. It has a 3.5 mm connection and is described as individually bagged, which can make distribution more orderly when different students or library users need their own set. The listing identifies the intended audience as teens, but the wired format may also be relevant to shared-device settings where a compatible headphone jack is available.
The product information lists PVC and silicone materials, sound isolation, and a 20 Hz to 20,000 Hz frequency range. Sensitivity is listed at 108 dB. Those specifications help identify the basic type of product, but they do not establish advanced call features, wireless connectivity, or a battery system. There is no charging or pairing routine to consider, though the plug still needs a compatible device.
The obvious trade-off is that Kanayu is a supply pack, not a single personal pair. Its fixed wired connection may be inconvenient if the listening device lacks a 3.5 mm jack. The available details also provide less information about cable length and controls than the Xuhal listing, so I would not assume those features are the same.
In my opinion, Kanayu makes sense when individually packaged sets are more useful than wireless features. For one person’s regular library sessions, I would choose a personal Bluetooth pair instead; for distributing earbuds across a group, this format is easier to understand and manage.
We compared the published design, connectivity, controls, battery information, and use-oriented features for each product. The ranking is our independent editorial opinion based on how well those details fit library listening and related needs. No brand paid for placement.
FAQ
No. The two Cillso models and WXQZXO Z500 use Bluetooth. Xuhal 200 and Kanayu 100 are wired and use 3.5 mm plugs, so they require a compatible headphone connection.
WXQZXO 2026 is the sleep-focused model. Its listed features include sleep mode, built-in white noise through an app, scheduled playback, and sleep tracking.
The listed Cillso and WXQZXO models are in-ear designs, while Xuhal and Kanayu are described as wired earbuds. The provided product details do not identify any of them as open-ear or clip-on headphones.
For an individual who wants a wireless set, I recommend the first Cillso option because it combines Bluetooth 5.4, touch controls, an LED case display, and up to 40 hours of stated total playback. For group distribution, the wired Xuhal or Kanayu packs may fit better if the devices have 3.5 mm jacks.
