If you want waterproof, built-in music for kids who swim, choose MARLALL Soft Liquid Silicone; if you need longer battery life and two-device Bluetooth for kids’ land-based workouts, choose Plufunex Bone Conduction Headphones. MARLALL is the clear fit for swimming because its MP3 mode is designed for underwater listening. Plufunex is the more versatile pick for everyday running, cycling, and school-to-workout listening, but it is not for underwater use.
• MARLALL’s biggest strength: IPX8 waterproof construction and built-in 32 GB MP3 storage for swimming; trade-off: Bluetooth does not work underwater, so swimming requires MP3 mode.
• Plufunex’s biggest strength: up to 13 hours of battery life and Bluetooth 6.0 multipoint for two paired devices; trade-off: its IP68 protection is for sweat and rain, not swimming or immersion.
• MARLALL fit: choose it for swim sessions and other activities where a soft silicone finish, open-ear design, and onboard music matter.
• Plufunex fit: choose it for land workouts, outdoor awareness, and moving between a phone and laptop without repeatedly pairing.
MARLALL is the swim-oriented option. Its IPX8-rated design and built-in 32 GB MP3 player make it the more practical choice of these two for listening in the water. The key catch is important: Bluetooth is not supported underwater. You need to use MP3 mode when swimming, and the product information says music from a phone app cannot be copied directly to the headphone’s memory. Playlist management instead uses the included magnetic charging cable and a computer connection to the internal storage.
The soft liquid silicone overmold and ergonomic ear-hook design are intended to keep the headphones comfortable and secure during swimming, diving, and workouts. Its open-ear format also leaves the ears unobstructed, which can help preserve awareness of nearby sounds during outdoor use. For a child who swims and wants stored music without relying on a phone connection in the pool, MARLALL has the more relevant design.
I would skip MARLALL if the main need is long wireless listening on dry land, seamless switching between two Bluetooth devices, or a stated battery run time beyond seven hours. The listed playback figure is up to seven hours after a 1.5-hour charge. The microphone should be dried after swimming to help prevent call issues, another small routine to keep in mind. Its strongest case is not that it does everything; it is that it addresses swimming in a way Plufunex does not.
Plufunex is built around land-based movement. Its open-ear design is intended to let users hear surrounding traffic and conversations while listening, and the wraparound ear-hook structure is meant to stay secure through activities such as running, cycling, hiking, and gym workouts. The adjustable 35-degree hooks provide a way to tune the fit, while the design is described as compatible with everyday and sports glasses. For a child who wears glasses and wants headphones for outdoor exercise, those details may matter more than a swim-specific seal.
Its standout practical advantage is battery and connection flexibility. Plufunex is specified for up to 13 hours of continuous battery life, with a 10-minute magnetic charge said to provide up to 75 minutes of listening. Bluetooth 6.0 multipoint lets it pair with two devices at once, such as a laptop and a phone. That could suit a family routine where a child listens from one device and still wants to remain connected to another.
The trade-off is the water boundary. The IP68 description covers sweat and rain, but the product is explicitly not intended for underwater swimming or water immersion. It therefore is not a substitute for MARLALL at the pool. I would also avoid assuming that “open-ear” means noise canceling: the listed noise control is none. This is a choice for awareness and convenience, not for blocking surrounding sound.
• Best for swimming and underwater listening → MARLALL Soft Liquid Silicone. Its IPX8 rating and onboard 32 GB MP3 storage are the deciding features; underwater playback uses MP3 mode, not Bluetooth.
• Best for running, cycling, and outdoor workouts → Plufunex Bone Conduction Headphones. Its secure wraparound design, adjustable hooks, and open-ear awareness are aimed at active land use.
• Best for longer listed battery life → Plufunex. It specifies up to 13 hours, compared with MARLALL’s up to seven hours.
• Best for music stored on the headphones → MARLALL. Its built-in 32 GB storage supports swim listening without an underwater Bluetooth connection.
• Best for switching between a phone and laptop → Plufunex. Bluetooth 6.0 multipoint supports pairing with two devices at once.
• Best for glasses compatibility → Plufunex. Its design is specifically described as fitting comfortably with everyday, prescription, and sports eyewear.
• Best for a child who wants one pair mainly for pool sessions → MARLALL. The trade-off is managing stored music through a computer rather than copying it directly from a phone app.
• Best for a child who wants open-ear headphones for land-based activity → Plufunex. Keep in mind that its water protection does not make it suitable for swimming.

The same distinction matters for people searching for the best hi res in ear headphones for kids. These are bone-conduction, open-ear designs rather than conventional in-ear earbuds, and the supplied specifications do not state high-resolution audio support. Likewise, neither is described as noise canceling, so someone seeking the best noise canceling sports earbuds for kids should not mistake open-ear awareness for noise reduction. The use case and fit matter more here than those search labels.
For sound and call expectations, the available information is limited. Both products use bone-conduction drivers, and both have no listed noise-control feature. MARLALL’s swimming mode depends on locally stored MP3 files, while Plufunex’s strengths are Bluetooth multipoint and longer stated playback. The data do not establish comparative sound quality, call clarity, or durability from testing, so I would choose based on the activity rather than assume one sounds better.
My Verdict
For kids who will listen while swimming, I would choose MARLALL Soft Liquid Silicone. Its IPX8 design and 32 GB onboard MP3 storage answer the pool-use need directly, provided the family is comfortable loading music through a computer and using MP3 mode underwater. For a child whose routine is mostly running, cycling, or everyday listening, I’d choose Plufunex instead for its longer stated battery life and multipoint pairing. But if I had to pick one for the primary use case of kids’ swimming, MARLALL is my recommendation.
The product is described as IPX8 waterproof and intended for swimming. Underwater listening requires MP3 mode; Bluetooth is not supported underwater. Music from a phone app cannot be copied directly to its memory.
No. Its IP68 protection is described for sweat and rain, and the product information says it is not intended for underwater swimming or immersion. Choose it for land-based workouts rather than pool use.
Plufunex lists up to 13 hours of continuous playback. MARLALL lists up to seven hours after a 1.5-hour charge, so its stated run time is shorter.
Plufunex is the more suitable option if you want to pair two devices and switch between them, such as a phone and laptop. MARLALL’s clearest distinction is onboard MP3 storage for swimming, not multipoint Bluetooth.

MARLALL Soft Liquid Silicone: Who It's For
MARLALL is the swim-oriented option. Its IPX8-rated design and built-in 32 GB MP3 player make it the more practical choice of these two for listening in the water. The important limitation is that Bluetooth is not supported underwater. You need to use MP3 mode while swimming, so this is not a matter of bringing a phone poolside and streaming as usual.
Getting music onto the headphones takes a little planning. The supplied information says the magnetic charging cable can connect the headphones to a computer for access to internal storage, but music from a phone app cannot be copied directly to the memory. For a child who swims regularly, that means a parent may need to prepare a playlist on a computer before a session. It is less convenient than streaming, but the stored music is what makes MARLALL suited to underwater use.
MARLALL lists up to seven hours of playback after a 1.5-hour charge. That may suit shorter listening routines, but it is the shorter battery specification here. The microphone should be dried after swimming to help prevent call issues, so there is also a small post-swim care step. I would skip MARLALL if you want two-device Bluetooth, longer stated playback, or a simple streaming setup. Its strongest case is swimming, not doing everything equally well.
Plufunex Bone Conduction Headphones: Who It's For
Plufunex is built around land-based movement. Its open-ear design is intended to let users hear surrounding traffic and conversations while listening, and its wraparound ear-hook structure is meant to stay secure through running, cycling, hiking, and workouts. The adjustable 35-degree hooks offer a way to customize the fit. The product information also describes compatibility with everyday glasses, prescription glasses, and sports eyewear.
Its standout practical advantage is battery and connection flexibility. Plufunex is specified for up to 13 hours of continuous battery life, with a 10-minute magnetic charge said to provide up to 75 minutes of listening. Bluetooth 6.0 multipoint lets it pair with two devices at once, such as a laptop and a phone. That could help a child move between a device used for school and a phone without repeatedly pairing from scratch.
The water boundary is the main trade-off. The IP68 description covers sweat and rain, but the product is explicitly not intended for underwater swimming or water immersion. So it may suit outdoor training in changing weather, but it is not a substitute for MARLALL at the pool. The listed noise control is also none. If the priority is reducing background noise, neither open-ear design is presented as a noise-canceling solution.
• Best for swimming and underwater listening → MARLALL Soft Liquid Silicone. Its IPX8 rating and onboard 32 GB MP3 storage are the deciding features; underwater playback uses MP3 mode, not Bluetooth.
• Best for running, cycling, and outdoor workouts → Plufunex Bone Conduction Headphones. Its secure wraparound design, adjustable hooks, and open-ear awareness are aimed at active land use.
• Best for longer listed battery life → Plufunex. It specifies up to 13 hours, compared with MARLALL’s up to seven hours.
• Best for music stored on the headphones → MARLALL. Its built-in 32 GB storage supports swim listening without an underwater Bluetooth connection.
• Best for switching between a phone and laptop → Plufunex. Bluetooth 6.0 multipoint supports pairing with two devices at once.
• Best for glasses compatibility → Plufunex. Its design is specifically described as fitting with everyday, prescription, and sports eyewear.
• Best for a child who wants one pair mainly for pool sessions → MARLALL. The trade-off is managing stored music through a computer rather than copying it directly from a phone app.
• Best for a child who wants open-ear headphones for land-based activity → Plufunex. Its water protection does not make it suitable for swimming.
The decision comes down to what “everyday use” means in your household. If a child’s regular routine includes swimming and the headphones need to work in the water, MARLALL has the more relevant feature set. If listening happens during walks, bike rides, or workouts on dry land, Plufunex offers a longer stated run time and a more flexible Bluetooth setup.
Some common searches describe needs that neither product clearly addresses. Someone looking for the best gaming headset for kids may care about a dedicated gaming microphone or a low-latency mode, but neither is specified here. Both are bone-conduction, open-ear headphones, and that alone does not make either a purpose-built gaming headset.
And if you are searching for the best noise canceling sports earbuds for kids, keep the design difference in mind. Neither product lists noise control. Their open-ear approach is intended to leave users aware of their surroundings, which may be useful for outdoor activity but is not the same as canceling background noise. For sound quality, call clarity, or long-term durability, the supplied specifications do not establish a winner through testing. I would make the choice based on water use, battery needs, and connection preferences instead.

Its IPX8 design and 32 GB onboard MP3 storage address the pool-use need directly, provided you are comfortable loading music through a computer and using MP3 mode underwater.
