If you want phone-free swimming with a dedicated fit adjustment, choose HIFI WALKER Bone Conduction Headphones; if you need a lighter design with newer Bluetooth, choose MONODEAL Bone Conduction Headphones. For kids bluetooth use, both offer open-ear listening and built-in music storage, but the HIFI WALKER’s adjustable tension band gives it an edge when a secure fit is the priority.
HIFI WALKER Bone Conduction Headphones vs MONODEAL Bone Conduction Headphones at a Glance
• MONODEAL’s biggest strength: a 29 g build, IP68 waterproofing, 32GB of storage, and Bluetooth 5.4; its trade-off is that it does not list a dedicated adjustable tension band.
• Both switch between Bluetooth and MP3 listening, and both list up to eight hours of battery life with a two-hour charge.
• Choose HIFI WALKER if adjustable fit and a stated swim mode lock matter most; choose MONODEAL if lower listed weight and Bluetooth 5.4 matter more.
• Neither is a conventional in-ear design: both use bone conduction and leave the ear canals open.
HIFI WALKER is the more swimming-focused choice on paper. Its IPX8 rating is specified for continuous immersion up to two meters, and its built-in 32GB memory lets you play saved audio without carrying a phone poolside. That matters because Bluetooth signals do not transmit underwater. For swimming, you need to switch to MP3 mode rather than expect a phone connection to continue beneath the surface.
The adjustable tension band is a useful point of difference. It is designed to help the headphones stay put across different head sizes, which may appeal to swimmers, runners, or active kids who need a stable fit. The open-ear design leaves the ear canals free, so surrounding sounds can still be heard. The stated swim mode lock and tactile controls are intended to help prevent accidental touches during activity.
The listed battery life is eight hours, with a two-hour charge. Bluetooth 5.3 supports wireless listening outside the water, such as during a walk or gym session. The product information also describes enhanced bass drivers and clearer vocals, but there is no noise control listed. Buyers should not expect it to block surrounding sound.

Who should skip it: Skip HIFI WALKER if you want Bluetooth music to stream while swimming, or if you specifically need an in-ear design that blocks ambient noise.
MONODEAL Bone Conduction Headphones: Who It's For
MONODEAL combines an IP68 waterproof rating with 32GB of built-in MP3 storage. Like HIFI WALKER, it must be in MP3 mode underwater: Bluetooth cannot carry a signal through the water. That makes the onboard memory central to its swimming use, while Bluetooth 5.4 covers listening and calls when you are back out of the pool and connected to a compatible phone, laptop, or tablet.
The battery figures match HIFI WALKER: eight hours of average life and a two-hour charge. The controls are described as push buttons, with a double-tap to change listening modes. That is a straightforward setup once learned, but buyers who prefer a stated adjustable tension band should note that MONODEAL does not list one. Its listed Bluetooth version is 5.4, compared with HIFI WALKER’s 5.3.
Who should skip it: Skip MONODEAL if your main requirement is a specifically described adjustable tension band or a listed swimming mode lock.
• Best for a stated adjustable fit → HIFI WALKER Bone Conduction Headphones. Its adjustable tension band is designed to help hold the headphones securely during movement.
• Best for the lower listed weight → MONODEAL Bone Conduction Headphones. It is listed at 29 g, a concrete advantage for anyone who prioritizes a lighter headset.
• Best for swimming with stored audio → Either one. Both have 32GB of built-in memory and require MP3 mode underwater.
• Best for the higher Bluetooth version → MONODEAL Bone Conduction Headphones. It uses Bluetooth 5.4, while HIFI WALKER lists Bluetooth 5.3.
• Best for a stated immersion depth → HIFI WALKER Bone Conduction Headphones. Its IPX8 description specifies continuous immersion up to two meters; MONODEAL lists IP68 but does not provide a depth figure in the available specifications.
• Best for a swimming mode lock → HIFI WALKER Bone Conduction Headphones. That feature is listed to help prevent accidental touches during activity.
• Best for a listed microphone and calls → MONODEAL Bone Conduction Headphones. It specifically includes a built-in microphone.
• Best for the phrase “best sweat resistant bluetooth earbuds” → Neither is described with a sweat-resistance rating. Both are open-ear bone conduction headphones with waterproof claims, but those claims should not be treated as a separate sweat-resistance specification.
Buying Considerations
For swimming, focus on how you will load and play audio rather than the Bluetooth version. Neither model streams from a phone underwater. Both provide 32GB of storage and an MP3 mode, so saved tracks or other audio are the practical route in the pool. Outside the water, Bluetooth is available on both.
Fit and weight are also worth separating. HIFI WALKER calls out an adjustable tension band, while MONODEAL provides a listed weight of 29 g. The available details do not give a comparable weight for HIFI WALKER, so I would not infer which one feels lighter overall from these sheets alone. For a secure fit, the band is a relevant feature; for a documented lightweight design, MONODEAL’s figure is useful.
Neither product is a standard pair of noise-isolating earbuds. Their open-ear bone conduction design leaves the ear canals uncovered, which can help you remain aware of nearby activity but also means environmental sound is not blocked. If you are searching for a “hi res headset for elderly,” note that neither sheet identifies a high-resolution audio certification or a dedicated accessibility feature. And if you want “extra bass sleep headphones,” these are positioned for sport and swimming, not sleep; HIFI WALKER mentions enhanced bass, but neither product is described as a sleep headset.
Finally, both list eight hours of battery life and a two-hour charge. MONODEAL specifies a microphone, while HIFI WALKER calls out a swim mode lock. Those differences are more useful for choosing between them than assuming either one will suit every sport or listening habit.

I would choose HIFI WALKER Bone Conduction Headphones for swimming and active use, especially for kids bluetooth listening where a stated adjustable tension band and swim mode lock are useful considerations. Its IPX8 description also gives a specific immersion depth, while its 32GB storage supports phone-free MP3 playback in the pool. MONODEAL is a strong alternative if the 29 g weight, Bluetooth 5.4, or built-in microphone matters more to you.
