If you want bone conduction freedom and a headband that fits under any swim cap for open-air awareness, choose KOPIDOE Swimming Headphones; if you need a secure in-ear seal with active isolation to cut through pool noise for focused laps, choose Clooissr IPX8.
• KOPIDOE Swimming Headphones: Strengths include its open-ear design for situational awareness and massive 32GB storage for thousands of songs without a phone. Trade-off is the reliance on MP3 mode underwater since Bluetooth signals do not transmit through water, plus it lacks active noise cancellation.
• Clooissr IPX8: Strengths feature a secure in-ear fit with rotatable hooks and passive noise cancellation to block out splashing and chatter. Trade-off is the smaller 8GB internal storage and the in-ear sensation which some find less comfortable for long durations than an open design.
• Who each pick is for: The KOPIDOE model suits swimmers who prioritize comfort and safety awareness, while the Clooissr unit is built for those who demand a tight seal and distraction-free audio in noisy environments.
The KOPIDOE Swimming Headphones are engineered for the swimmer who refuses to sacrifice situational awareness. Their defining characteristic is the open-ear bone conduction technology, which sits comfortably around your ears rather than plugging them. This design keeps your ear canals completely free, ensuring that even during extended training sessions, you feel zero pain or pressure. You remain aware of your surroundings, whether that means hearing lane markers, poolside announcements, or simply enjoying the ambient sounds of the facility without isolating yourself from the world.
For the traveler or the frequent flyer, this specific design offers a unique advantage. While these headphones are primarily marketed for the pool, their ability to sit securely without blocking the ear canal makes them a viable option for for airplane travel. Unlike traditional earbuds that create pressure or leak sound, the open design allows you to enjoy music or podcasts while still being able to hear flight attendants or other passengers if necessary. The adjustable headband ensures a stable fit that works seamlessly with swim caps, hats, or even standard aviation headsets, making it a versatile piece of gear beyond just the pool deck.

You should buy the KOPIDOE if you value battery longevity and massive offline storage. With a built-in 32GB memory card, you can store over 80,000 songs directly on the device, meaning you never have to drag your phone into the locker room or the pool area. The magnetic charging port adds a layer of convenience and safety, allowing for quick power-ups. However, you should skip this model if you require deep bass or complete silence. Because the drivers vibrate against your cheekbones rather than sealing inside your ear, the audio profile is naturally different, and there is no active noise cancellation to drown out the chaotic sounds of a busy gym or a crowded plane cabin.
The Clooissr IPX8 targets the athlete who treats swimming as a serious, data-driven workout where focus is paramount. These are true in-ear earbuds designed with a secure hook system that rotates up to 30 degrees, allowing you to customize the angle to fit your specific ear shape perfectly. The package includes three sizes of specialized swim earplugs (S, M, L), ensuring that regardless of your anatomy, you can achieve a waterproof seal that prevents water from entering the ear canal. This physical barrier, combined with passive noise cancellation, creates a quiet bubble that helps you maintain rhythm and concentration, even when the pool deck is loud.
This product is particularly compelling for users who struggle with the "one-size-fits-none" issue common in many swimming accessories. The rotatable ear hooks and soft silicone materials are designed to eliminate the slipping that often happens during flip turns or intense sprints. If you have ever experienced earbuds falling out mid-lap, the Clooissr engineering addresses that directly by locking the driver into place. The 12mm dynamic drivers are tuned specifically for underwater acoustics, delivering balanced audio that cuts through the distortion caused by water pressure changes. This makes it an excellent choice for anyone looking for in ear earbuds for basketball training or similar high-intensity sports where stability is non-negotiable.
However, the Clooissr comes with trade-offs regarding storage and comfort preferences. The internal storage is limited to 8GB, which holds approximately 1,500 songs—significantly less than the KOPIDOE's capacity. You may need to curate your playlists more strictly or rely on your phone via Bluetooth when you are out of the water. Furthermore, while the in-ear design offers superior isolation, it does not offer the same level of environmental awareness as bone conduction. If you prefer to hear your surroundings or if you find in-ear devices uncomfortable after a few hours of wear, this model might not be the right fit for your daily routine.
• Best for Battery Life and Storage → KOPIDOE Swimming Headphones: With 32GB of onboard memory, you can carry a vast library of music without needing a phone, whereas the Clooissr is capped at 8GB.
• Best for Secure Fit and Stability → Clooissr IPX8: The rotatable ear hooks and multiple ear tip sizes provide a mechanical lock that outperforms the headband design during vigorous flip turns.
• Best for Situational Awareness → KOPIDOE Swimming Headphones: The open-ear design lets you hear the world around you, a critical safety feature for outdoor swimmers or those using the device for bluetooth earbuds for hunting scenarios where hearing game or footsteps is essential.
• Best for Noise Isolation → Clooissr IPX8: The passive noise cancellation and in-ear seal actively block out pool chatter and water noise better than the open bone conduction alternative.
• Best for Comfort During Long Wear → KOPIDOE Swimming Headphones: Many users report that the lack of pressure in the ear canal makes the headband style superior for marathon-length sessions compared to in-ear plugs.
• Best for Versatility Across Environments → Clooissr IPX8: While both work in water, the Clooissr's secure fit makes it more adaptable for running, cycling, and gym workouts where the headband might bounce.
• Best for Ease of Use with Accessories → KOPIDOE Swimming Headphones: The headband design is explicitly compatible with swim caps and hats, whereas the Clooissr requires tucking the earbuds under the cap for maximum security.
• Best for Audio Clarity Underwater → Clooissr IPX8: The dynamic drivers and specific tuning for underwater acoustics generally deliver clearer sound quality below the surface compared to bone conduction vibration.
In my opinion, I would choose the Clooissr IPX8 for serious lap swimming because the secure fit and noise isolation are non-negotiable for maintaining a rhythm in a busy pool. The ability to rotate the ear hooks ensures they stay put, and the passive noise cancellation creates the focus needed for training. However, if your primary use case involves for airplane travel or open-water swimming where hearing your environment is a safety priority, the KOPIDOE Swimming Headphones become the clear winner. Its open-ear design offers a level of versatility and comfort that in-ear buds simply cannot match in those specific scenarios. Ultimately, if you need isolation, go Clooissr; if you need awareness, go KOPIDOE.
While the KOPIDOE features a lightweight design suitable for various ages, the in-ear nature of the Clooissr makes it potentially tricky for very young children who may not tolerate earplugs well. Parents often look for best sleep headphones for children, and the open-ear design of the KOPIDOE is generally safer and more comfortable for sensitive ears than the sealed in-ear alternative.
No, neither product supports Bluetooth connectivity while submerged because radio waves do not travel through water effectively. Both devices require you to switch to their respective MP3 modes to play music stored on their internal drives once you are underwater.
The KOPIDOE boasts a long battery life designed for extended sessions, while the Clooissr offers up to 10 hours of Bluetooth playback and 8 hours of continuous MP3 music. Both are sufficient for most training days, but the KOPIDOE's larger storage means you won't run out of songs to listen to before you run out of charge.
Yes, both models are marketed for running and cycling. The Clooissr is particularly noted for its stability during high-movement activities due to its in-ear hook design, while the KOPIDOE provides the situational awareness preferred by runners who need to hear traffic. Some users also find the KOPIDOE suitable for bluetooth earbuds for hunting due to the open-ear capability.
