If you want a playful, in-ear fit with noise cancellation for small ears, choose MOROZKISPA Cartoon Cat Earbuds; if you need open-ear headphones for swimming and active use, choose POPUX Bone Conduction Headphones. The key difference is simple: MOROZKISPA uses rounded in-ear tips, while POPUX sits outside the ear and is built around a waterproof, adjustable design.
For everyday listening, calls, and workouts where you want to block some background noise, MOROZKISPA is the more natural fit. For swimming, running, or listening without covering the ear canal, POPUX brings features that MOROZKISPA does not.
• MOROZKISPA’s biggest strength: rounded in-ear tips, active noise cancellation, touch controls, and up to 28 hours of stated battery life with the case. Trade-off: IPX4 water resistance is for splashes and sweat, not underwater use.
• POPUX’s biggest strength: an open-ear bone-conduction design with an IP68 rating, adjustable fit, and built-in 32GB storage for MP3 playback. Trade-off: its stated playback time is up to 10 hours in Bluetooth mode and 6 hours in MP3 mode.
• Choose MOROZKISPA for compact in-ear listening, a playful cartoon look, and background-noise reduction.
• Choose POPUX for swimming, open-ear listening, and workouts where a secure adjustable frame and onboard music storage matter.
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, which may suit a listener seeking ear clip headphones for small ears better than a larger over-ear style. The product information describes an in-ear design, though it does not give tip measurements or a range of fit sizes. Small ears are personal, so the listed design alone cannot guarantee a comfortable fit for everyone.

Its practical strengths are active noise cancellation, touch controls, Bluetooth 5.1, and a stated battery life of up to 28 hours with the case. That combination makes it appealing for commutes, study sessions, and everyday listening when you would rather reduce background noise than stay fully aware of your surroundings. IPX4 protection makes it suitable for sweat and splashes during ordinary workouts, but it is not the pick for swimming.
The cartoon styling gives these earbuds a distinct look, and the product is described for adults, teens, and children. A parent looking for a best kids headset for small ears might consider its in-ear format and playful design, but should still pay attention to the individual child’s fit. Skip it if you need open-ear listening, a swimming-capable waterproof headset, or an adjustable frame rather than earbuds inserted into the ears.
POPUX takes a different approach: its open-ear bone-conduction design leaves the ear canal uncovered. The flexible titanium-alloy frame and adjustable strap are intended to keep the headphones in place during activity. The stated weight is 25 grams. This setup may appeal if in-ear tips are uncomfortable or if you prefer to remain more aware of surrounding sounds while moving. It is not an earbud with a small tip; it rests outside the ear.
Its strongest distinction is the IP68 rating, with swimming specifically part of the product’s intended use. It also offers Bluetooth 5.4 and 32GB of built-in storage for MP3 playback, so you can listen from the headphones without carrying a phone for that mode. The listed playback claims are up to 10 hours in Bluetooth mode and 6 hours in MP3 mode. Physical buttons are another useful choice for operating music and calls while moving or with wet hands.
The trade-off is that POPUX does not offer the in-ear seal or active noise cancellation listed for MOROZKISPA. Open-ear listening is useful when awareness matters, but it is not the same as blocking out surrounding sound. Choose it if swimming and a stable, adjustable fit are central needs. Skip it if you specifically want compact earbuds that sit inside small ears or want active noise cancellation for quieter listening.

My Verdict
FAQ
They have rounded in-ear tips and an ergonomic design intended for a snug fit. The product information does not list tip dimensions or multiple tip sizes, so it cannot confirm how they will fit a particular person’s ears.
POPUX has an IP68 rating and is designed for swimming, but it is an open-ear bone-conduction headset with an adjustable frame, not a small in-ear model. It may suit someone avoiding ear tips, but the listing does not provide small-ear fit measurements.
POPUX is the relevant choice for swimming because its IP68 rating and stated use include underwater activity. Its listed features also include a noise-cancelling microphone, but the product details do not provide comparative call-quality results.
MOROZKISPA lists up to 28 hours with its case. POPUX lists up to 10 hours in Bluetooth mode and 6 hours in MP3 mode, so compare those figures with how you plan to use the headphones.
