If you want a snug in-ear fit with active noise cancellation for focused library listening, choose MOROZKISPA Cartoon Cat Earbuds; if you need an open-ear clip-on design that keeps you aware of nearby sounds, choose SoundAI FairyClip A2. For a library, I lean toward MOROZKISPA for its noise-blocking design, while SoundAI makes more sense when hearing your surroundings matters.
• MOROZKISPA strength: In-ear design, active noise cancellation, and up to 28 hours of battery life with the case. Trade-off: Its snug fit and noise-blocking approach are less suited to someone who wants to hear ambient sounds.
• SoundAI strength: Open-ear clip-on fit, Bluetooth 5.4, and up to 28 hours of total battery life. Trade-off: An open design lets in nearby sounds, which can make it harder to focus in a busy place.
• For MOROZKISPA: Choose it for a more enclosed listening experience, library study, and a playful cartoon look.
• For SoundAI: Choose it for open-ear awareness, clip-on wear, physical buttons, and built-in AI functions.
MOROZKISPA is the more conventional choice for someone who wants earbuds that sit inside the ears. Its rounded tips and ergonomic design are intended to provide a snug fit, while active noise cancellation aims to reduce background noise. That combination makes it the more natural fit for quiet, focused listening in a library, especially when the nearby room sounds are distracting.
The advertised battery life is up to 28 hours, and the earbuds use Bluetooth 5.1 with memory pairing. Smart touch controls handle music and calls, and an indicator light provides status information. The IPX4 rating offers resistance to splashes, so these earbuds can also suit a workout or a walk where light moisture is a concern. That rating should not be mistaken for protection against submersion.
The cartoon cat design is a clear part of the appeal. I would consider MOROZKISPA if you want a compact in-ear style with a playful look, active noise cancellation, and a long stated total battery life. Skip it if you prefer open-ear listening, want to hear conversations and traffic easily, or dislike the feeling of earbuds sitting in the ear.

The FairyClip A2 pairs over Bluetooth 5.4 and is listed with up to 28 hours of battery life. It includes physical buttons, a low-latency game mode, and app-based customizable EQ settings. The feature list also describes AI translation, a smart assistant, summaries, and a find function. Those tools may appeal to someone who expects to use earbuds for more than music, though the product information does not explain every supported language or how each AI function works.
SoundAI also highlights directional audio intended to reduce sound leakage, along with an ambient-aware listening design. The earbuds have an IPX4 rating, and the described package includes a charging case and pearl bracelet. I would look at the FairyClip A2 if you value an open fit, want a clip-on design, or expect to use its listed AI features. Skip it if your main goal is a sealed-feeling fit for concentrated listening or strong isolation from the room.
• Best fit for focused library listening: MOROZKISPA. Its in-ear design and active noise cancellation are the more relevant features when your goal is to reduce distractions.
• Best for staying aware of the room: SoundAI. Its open-ear design is meant to let ambient sounds through while you listen.
• Best for a playful cartoon style: MOROZKISPA. The cartoon theme is a defining part of its design.
• Best for a clip-on open-ear fit: SoundAI. Its clip-on shape differs from traditional in-ear earbuds and is aimed at people who prefer not to insert earbuds into the ear canal.
• Best stated total battery life: It is a tie on the available figures: both products list up to 28 hours. SoundAI also specifies four hours of playtime per charge, with 28 hours total when using its charging case.
• Best for a newer Bluetooth version: SoundAI, with Bluetooth 5.4 compared with MOROZKISPA's Bluetooth 5.1.
• Best for physical controls: SoundAI, whose listed controls include physical buttons. MOROZKISPA instead uses smart touch controls.
• Best for water resistance during light exposure: Neither has a stated advantage here. Both list IPX4, which is for resistance to splashes, not submersion.
• Best for AI tools: SoundAI, which lists translation, assistant, summary, and find functions. MOROZKISPA's listed controls focus on music and calls.
• Best for a quieter listening setup: MOROZKISPA is the more fitting choice based on its in-ear construction and active noise cancellation. SoundAI's open design prioritizes awareness, not blocking the room.
Likewise, neither product is described as bone conduction. If you are looking for waterproof bone conduction headphones for library use, these two are not that type of headphone: MOROZKISPA is in-ear, and SoundAI is open-ear clip-on. Both carry an IPX4 rating, but that does not make either one suitable for submersion.
There is another useful distinction for study routines. SoundAI's smart assistant and translation functions could be appealing for language work or quick voice interactions. MOROZKISPA is more straightforward: its appeal is the in-ear form, touch controls, noise cancellation, and stated battery life rather than a collection of AI tools.
My Verdict
In my opinion, I would choose MOROZKISPA Cartoon Cat Earbuds for library use because its in-ear design and active noise cancellation better match a need for focused listening. Its cartoon styling and up-to-28-hour stated battery life are useful extras, not the main reason I would pick it.
I would choose SoundAI FairyClip A2 instead if I wanted an open-ear clip-on fit, awareness of nearby sounds, or its listed AI features. For a library, my recommendation is MOROZKISPA unless keeping your ears open is more important than reducing distractions.
MOROZKISPA is the more suitable option for focused listening because it has an in-ear design and active noise cancellation. SoundAI is open-ear, which is useful for hearing the room but may leave more ambient sound audible while you study.
No. MOROZKISPA is an in-ear earbud, and SoundAI is an open-ear clip-on earbud. Both list IPX4 water resistance, but neither is described as a bone conduction model.
Both list up to 28 hours of battery life. SoundAI's product description further states four hours of playtime per charge and up to 28 hours total with the charging case; the available MOROZKISPA details describe 28 hours for the case battery.
SoundAI lists AI translation, a smart assistant, summaries, and a find function, as well as app-based EQ settings and a low-latency game mode. MOROZKISPA focuses on Bluetooth pairing, touch controls, active noise cancellation, and an indicator light. Check the current price on Amazon if price is part of your decision.
