If you want headphones with touch controls, Bluetooth 5.0, and passive noise reduction for a library, choose Zerodis Headphones; if you need a charging case that can also charge a phone and provide a flashlight, choose Keenso Earbuds. For a quieter, simpler listening setup, I’d choose Zerodis; for extra functions built into the case, Keenso has the more distinctive design.
• Zerodis Headphones: In-ear wireless design with Bluetooth 5.0, touch media controls, and passive noise cancellation; the sheet gives no battery capacity or charging-case details.
• Keenso Earbuds: LED battery display and a case that can charge earbuds and a phone, plus a flashlight; the sheet does not specify Bluetooth version or noise control.
• Zerodis is for listeners who prioritize touch control, a stable-connection feature, and reduced outside-noise interference.
• Keenso is for people drawn to a multipurpose charging case, Type-C charging, and automatic reconnection.
• For a library, Zerodis has the clearer fit on paper because it specifically lists noise reduction; neither product sheet establishes how much sound it blocks.
Zerodis is an in-ear wireless headphone set with rounded tips, a dynamic driver, Bluetooth 5.0, and touch media controls. Its listed noise control is passive noise cancellation, while the product description also says upgraded noise-reduction technology is intended to reduce outside interference. That makes it the more straightforward match for someone who wants music to feel less exposed to nearby sounds while studying or working.
There are a couple of practical touches here. A digital display shows remaining battery power and volume, so the listing describes a way to check those details and adjust listening without guessing. The headphones are also described as using ABS material intended to resist scratches and impacts. Those features suggest a design focused on simple monitoring and everyday handling, though the sheet does not give battery capacity, runtime, or a charging-case specification.
For someone searching for headphones for library use, Zerodis is the more relevant choice based on the stated passive noise control. That does not establish that it will silence conversation, room noise, or other distractions. It only gives a specific reason to consider it ahead of Keenso for this setting. The comfort description also presents the in-ear fit as suitable for long wear, but individual comfort depends on fit.

Who should skip it: Skip Zerodis if you specifically want a case with phone-charging and flashlight functions, or if you need documented battery runtime before choosing.
The listing describes a soft composite diaphragm intended to create rich stereo sound with layered midrange and bass. It also says that, after the first successful pairing, the earbuds automatically reconnect to the device. In daily use, that could make repeat listening more convenient than manually pairing each time. The listed wireless distance is approximately 10 meters, and the 1200mAh case battery is described as capable of charging the earbuds six to eight times. Those are useful details, but they do not provide a single stated listening-runtime figure for one charge.
Keenso may suit someone who wants a versatile set for everyday wireless listening and likes the idea of a case that does more than store and charge earbuds. Its sheet does not list noise control or a Bluetooth version, so there is less concrete support for choosing it specifically as a quiet-study option. It includes two earbuds and four eartips, which gives the package more fit options than the Zerodis details specify.
Who should skip it: Skip Keenso if passive noise control is a priority or if you need a stated Bluetooth version before buying.

• Best for automatic reconnection → Keenso Earbuds. The listing says they reconnect automatically after the first successful pairing.
• Best for a stated wireless range → Keenso Earbuds. Its listed distance is approximately 10 meters; the Zerodis sheet gives no wireless-distance figure.
• Best for a stated charging-case capacity → Keenso Earbuds. Its case is listed with a 1200mAh battery and a stated six-to-eight earbud charges.

• Best for Type-C charging → Keenso Earbuds. Its sheet specifically identifies Type-C fast charging.
The phrase wireless headphones for library covers more than one kind of need. Some listeners want a clearly stated noise-control feature; others care more about battery monitoring or easy reconnection. From the available details, Zerodis answers the first need more directly, while Keenso’s strengths are convenience features around its case.
Neither product has enough information in the sheet to support every common comparison. For example, the Zerodis details do not state battery capacity or listening time, and the Keenso details do not name a Bluetooth version or noise-control mode. If those are deciding factors for you, treat them as unknown rather than assuming one product has an advantage.
Think about where you’ll use the earbuds most. For studying in a shared room or looking for a best gaming headset for library option, the key question is whether you want a stated noise-control feature or a multipurpose case. Zerodis lists passive noise cancellation and noise-reduction technology, so it has the more relevant feature on paper. But neither sheet establishes how much ambient sound gets through, and neither should be treated as a substitute for a dedicated gaming headset based on these details alone.
The battery information is uneven. Zerodis has a display described as showing remaining battery power, but no capacity or runtime is supplied. Keenso provides more case information: a 1200mAh battery and a claim that it can recharge the earbuds six to eight times. That does not tell you how long the earbuds play between charges, so it is helpful for understanding case capacity but not a full estimate of total listening time.
Also consider which small conveniences you’ll actually use. Touch media controls and a display for volume may appeal to someone who wants quick adjustments with Zerodis. Keenso’s Type-C charging, automatic reconnection, phone-charging case, and flashlight may be more useful to someone who values an all-in-one accessory. These are different priorities, not proof that one model has better sound or overall durability.
If your decision depends on comfort, sound isolation, or how either model handles a particular device, the supplied specifications do not settle those questions. Both are listed as in-ear wireless products, but fit and listening preference can vary. Check the current product details on Amazon before deciding, especially for any feature that is essential to your setup.
My Verdict
In my opinion, I’d choose Zerodis Headphones for a library because passive noise cancellation and noise-reduction technology are the most directly relevant features for that setting. Its touch controls and battery-and-volume display add useful convenience, too. I’d choose Keenso instead if the phone-charging case, flashlight, Type-C charging, or stated case capacity matters more than listed noise control.
Are Zerodis Headphones or Keenso Earbuds better for a library?
Zerodis is the more directly supported choice because its sheet lists passive noise cancellation and noise-reduction technology. Neither product sheet says how much outside sound is blocked, so don’t assume either one will make a noisy space silent.
Keenso has the more extensively described case: it can charge the earbuds and a phone, includes a flashlight, and uses Type-C charging. Its 1200mAh battery is stated to recharge the earbuds six to eight times.
Zerodis lists passive noise cancellation and noise-reduction technology. Keenso’s provided details do not list a noise-control feature. That makes Zerodis the clearer pick on this specific point, but the information does not quantify the level of noise reduction.
Keenso is the one whose description states that it automatically reconnects after the first successful pairing. Zerodis lists Bluetooth 5.0 and touch media controls, but its supplied details do not describe automatic reconnection.
