If you want headphones with long battery life and wired fallback for everyday listening for kids, choose TuneFlux Headphones Over Ear; if you need waterproof bone-conduction headphones for swimming for kids, choose Feiltik Swimming Headphones Underwater.
TuneFlux Headphones Over Ear vs Feiltik Swimming Headphones Underwater at a Glance
• TuneFlux’s biggest strength: Up to 80 hours of battery life, three EQ modes, and a 3.5 mm cable for wired listening. Main trade-off: It is an over-ear design, not a swimming headphone. - Feiltik’s biggest strength: IPX8 waterproofing, open-ear bone conduction, and 32GB of built-in music storage for underwater listening. - Choose TuneFlux for home, travel, or general listening where long playback and wired backup matter. - Choose Feiltik for swimming and other water activities where waterproofing and onboard MP3 playback are the priorities.
TuneFlux is the more straightforward fit for everyday listening. Its over-ear design uses 40 mm dynamic drivers, and its wireless connection uses Bluetooth 5.3. The listed Bluetooth range is 33 feet, which gives a listener some room to move away from a paired device, though walls and surroundings can affect any wireless connection. Three EQ modes let the listener choose between a balanced presentation, boosted bass, and a high-definition setting. That gives kids or adults a few ways to adjust the sound without needing a separate equalizer.
Battery life is the headline practical advantage. TuneFlux is listed for up to 80 hours of playback, with a stated full charge time of 2.5 hours. A 10-minute charge is described as providing an additional five hours of playtime, a useful detail for a child who remembers to charge only shortly before a car ride or a long stretch of listening. It also supports wired use through the included 3.5 mm audio cable, so listening does not have to stop simply because the battery is depleted. Dual-device connectivity is another convenience for switching between two paired devices.

Who should skip it: Skip TuneFlux if the main need is headphones for swimming, or if an over-ear headset is not the style you want.
Feiltik Swimming Headphones Underwater: Who It's For
Feiltik serves a much narrower, water-focused purpose. It is listed as IPX8 waterproof and designed for swimming and other water activities. Its open-ear bone-conduction design keeps the ear canals unobstructed rather than relying on conventional in-ear listening. The package information includes swimming earplugs, a protective case, and a magnetic charging cable. Those details make it a specialized option for someone who wants audio equipment intended for use around water, rather than a general-purpose headset that must be kept dry.
The key point is how playback works. Feiltik’s Bluetooth 6.0 connection is for use on land; Bluetooth does not work underwater, so swimming requires switching to MP3 mode. The headphones have 32GB of built-in storage, described as holding up to 8,000 songs. That means a swimmer can listen to stored audio without needing a phone to maintain a wireless connection in the pool. Feiltik also supports pairing with two devices, which can be handy outside the water. Charging is magnetic, and the product information lists no headphone jack.
Who should skip it: Skip Feiltik if you need Bluetooth streaming while underwater, a 3.5 mm wired fallback, or a stated playback-time figure before choosing.
• Best for swimming → Feiltik Swimming Headphones Underwater. Its IPX8 rating and underwater MP3 mode are the relevant features; TuneFlux is not described as waterproof.
• Best for long stated battery life → TuneFlux Headphones Over Ear. It is listed for up to 80 hours per charge, while Feiltik’s data sheet does not state battery life.
• Best for listening underwater → Feiltik Swimming Headphones Underwater. Use its built-in MP3 storage, because Bluetooth does not work underwater.
• Best for wired backup → TuneFlux Headphones Over Ear. It includes a 3.5 mm audio cable and supports wired listening.
• Best for choosing a sound mode → TuneFlux Headphones Over Ear. Its three EQ options cover balanced, bass-boosted, and high-definition listening.
• Best for open-ear bone conduction → Feiltik Swimming Headphones Underwater. That design leaves the ear canals clear, unlike TuneFlux’s over-ear setup.
• Best for pairing two devices → Either, with different details. Both list dual-device connectivity; Feiltik specifies Bluetooth 6.0, while TuneFlux specifies Bluetooth 5.3.
• Best for the search for fast charging kids headphones for kids → Neither can be confirmed as the clear pick. TuneFlux lists a 10-minute charge for five hours of playback, while Feiltik has magnetic charging but no charging-time or battery-life figure.
Before choosing, think about the setting first. A child who mainly listens at home, during travel, or with a computer has a better match in TuneFlux’s over-ear design and wired option. A child who swims needs a product specifically described for water use. Feiltik’s underwater listening depends on downloaded or otherwise stored audio in its MP3 memory, not a phone streaming over Bluetooth in the pool.
Consider the trade-off between a broad everyday role and a specialized swimming role. Feiltik provides waterproofing and built-in storage, but it has no listed battery duration, and underwater use involves changing to MP3 mode. Neither data sheet gives enough information to promise that a particular child will find the fit ideal. For a child, that makes the intended setting and preferred wearing style especially important.
Charging expectations may settle the decision for some families. TuneFlux states both a 2.5-hour full charge and a short-charge playtime figure. Feiltik’s magnetic charging design avoids a conventional charging port, but no charging duration is supplied. If you are comparing the best fast charging kids headphones for kids, only TuneFlux provides a specific quick-charge claim here; that does not establish how quickly Feiltik charges.
I would choose TuneFlux for a child who needs everyday headphones, because its 80-hour stated playback, three EQ modes, and wired fallback make it the more versatile option outside the water.
For kids who will use headphones while swimming, I would choose Feiltik instead: its waterproof design and onboard MP3 storage address that use directly. I would not treat the two as interchangeable.
No. The product information says Bluetooth does not work underwater. For swimming, switch to MP3 mode and listen to audio stored in its built-in 32GB memory.
The TuneFlux data sheet describes an over-ear Bluetooth headset and does not list a waterproof rating. I would not choose it for swimming based on the supplied information.
TuneFlux is listed for up to 80 hours of playback per charge. The Feiltik data sheet does not provide a battery-life figure, so there is no stated figure to compare.
For ordinary listening, TuneFlux has the advantage of a stated long playback time and a wired option, though its age description is adult. For swimming, Feiltik is the purpose-built choice and its age-range description includes kids. The right pick depends on where the child will use the headphones.
