If you want a simple wireless headset for everyday listening, choose AMPACO Headset; if you need dedicated underwater playback for audiophiles, choose KOPIDOE Swimming Headphones Underwater. The key difference is how each handles swimming: AMPACO offers Bluetooth earbuds, while KOPIDOE requires MP3 mode in the water and has built-in storage.
AMPACO Headset vs KOPIDOE Swimming Headphones Underwater at a Glance
• AMPACO Headset strength: Wireless Bluetooth earbuds with touch media controls and a microphone. Trade-off: Its listed features do not describe built-in music storage or bone-conduction playback for swimming underwater.
• KOPIDOE strength: IP68 waterproof bone-conduction headphones with 32GB of built-in storage for MP3 listening. Trade-off: You must switch to MP3 mode for swimming because Bluetooth does not work underwater.
• AMPACO Headset fit: Choose it if you want an in-ear wireless headset for general listening and value having a microphone.
• KOPIDOE fit: Choose it if you want open-ear headphones designed for swimming and can prepare music on the device before getting into the water.
AMPACO is an in-ear wireless headset with Bluetooth connectivity, touch media controls, and a built-in microphone. Its listed design is straightforward: a plastic enclosure, a black finish, and an in-ear form. The product information also describes it as lightweight and rechargeable. Those features point toward everyday wireless listening rather than a device centered on stored music or a specialized underwater playback system.
The microphone may matter if you want a headset that can handle more than music, such as calls or voice communication when the surrounding conditions are appropriate. Touch controls give you a way to manage media on the headset itself. For someone looking for a compact, conventional wireless earbud-style option, those are useful basics.
I would consider AMPACO if my priority were an in-ear Bluetooth headset for general use, and I would not choose it on the assumption that it can play music underwater. The product information calls it waterproof, but the listed details do not specify an IP rating or explain an underwater MP3 mode. That makes it a less clearly defined swimming choice than KOPIDOE. Buyers who specifically need open-ear bone conduction or built-in MP3 storage should look elsewhere.

Its most consequential swimming feature is the built-in 32GB storage. Bluetooth does not work underwater, so the instructions call for switching to MP3 mode before swimming. That means you can listen to music stored on the headphones without relying on a phone connection beneath the surface. Bluetooth 6.0 is listed for wireless use, and the headphones support pairing with two devices, but that does not remove the need for MP3 mode in the water.
KOPIDOE is the more natural choice for a swimmer who wants music during a pool session and is willing to prepare their listening in advance. Its IP68 rating, bone-conduction design, adjustable headband, and built-in storage give it a more specific swimming focus. The trade-off is that it is not the simplest option for someone who expects Bluetooth streaming to continue underwater. And while it may suit people searching for kids headphones for audiophiles, the listed age range is adult, so I would not treat it as a child-specific fit.
• For swimming with music stored on the headphones → KOPIDOE Swimming Headphones Underwater. Its 32GB of built-in storage and MP3 mode are the clearest fit for underwater listening. Remember to switch modes before swimming.
• For a conventional in-ear Bluetooth headset → AMPACO Headset. It has wireless Bluetooth connectivity and an in-ear design, while KOPIDOE uses open-ear bone conduction.
• For open ears and awareness of surroundings → KOPIDOE Swimming Headphones Underwater. Its open-ear design leaves the ear canals uncovered. That may appeal for workouts and other situations where hearing the environment matters.
• For a built-in microphone → AMPACO Headset. A microphone is explicitly listed for AMPACO; no microphone is specified for KOPIDOE.
• For touch media controls → AMPACO Headset. Its control method is listed as touch. KOPIDOE’s information does not specify touch controls.
• For an adjustable fit intended to work with a swim cap or hat → KOPIDOE Swimming Headphones Underwater. Its adjustable headband and compatibility with caps and hats are part of its stated design.
• For Bluetooth use with two devices → KOPIDOE Swimming Headphones Underwater. Dual-device pairing is listed, though Bluetooth is not the mode to use underwater.
• For someone searching for the best headset for audiophiles → decide by listening setup, not the label. Neither set of specifications establishes audiophile-grade sound. KOPIDOE is the more practical fit for music during swimming; AMPACO suits someone who prefers in-ear Bluetooth listening and wants a microphone.
The phrase “best on ear headphones for audiophiles” also deserves a small clarification here: neither product is described as an on-ear headphone. AMPACO is in-ear, while KOPIDOE is open-ear bone conduction. If you specifically want a traditional on-ear fit, these two are not direct matches for that preference.
That difference affects preparation. With AMPACO, the listed features describe a Bluetooth headset but do not specify a way to load and play tracks independently. With KOPIDOE, the built-in storage gives you an option for listening without carrying your phone into the water, but you need to use MP3 mode while swimming. If your routine includes both a phone-based playlist on land and a pool session, the mode switch is important rather than a minor detail.
Fit is another meaningful separator. Some listeners prefer earbuds that sit in the ear; others want the ear canal left open. AMPACO follows the first design. KOPIDOE follows the second and adds an adjustable headband intended to fit different head sizes and work with swim caps or hats. Those descriptions help narrow the choice, but they do not establish that either fit will feel right for every individual.
For sound-focused shoppers, I would keep expectations grounded in what is actually specified. KOPIDOE’s product information identifies a bone-conduction driver, while AMPACO is described as TWS stereo earbuds. Neither sheet supplies detailed frequency response, codec information, or other measurements that would support a definitive sound-quality ranking. If sound quality is your main concern, the design and intended use can guide your shortlist, but these facts alone do not prove which one sounds better.
My Verdict
In my opinion, I would choose KOPIDOE Swimming Headphones Underwater if I wanted music during pool sessions: its IP68 rating, adjustable open-ear design, and 32GB of MP3 storage serve that use more directly. For audiophiles, I would still treat it as a practical swimming choice, not as a proven high-fidelity upgrade. I would choose AMPACO Headset instead for everyday in-ear Bluetooth listening and its listed microphone. My recommendation is KOPIDOE, because the swimming use case is where the two products differ most clearly.
FAQ
AMPACO lists a built-in microphone, so it is the clearer choice if having a microphone is important. KOPIDOE’s product information does not specify one. The available details do not establish how either headset performs in a particular call environment.
KOPIDOE is the more swimming-focused option in the listed specifications. It has an IP68 rating, an adjustable fit designed to work with swim caps or hats, and MP3 playback from built-in storage. You still need to switch out of Bluetooth mode before entering the water.
Neither product’s listed specifications are enough to establish audiophile-grade sound or prove that one has superior audio quality. Choose based on the listening setup you need: KOPIDOE for stored music during swimming, or AMPACO for an in-ear Bluetooth headset with touch controls and a microphone.
