If you want a waterproof headphone with built-in offline music for a kid, choose mojawa Run Plus Bone; if you need a smaller-head fit for running and gym workouts, choose Shokz OpenRun Mini Bone. The Run Plus is the more capable pick for swimming and listening without a phone nearby. The OpenRun Mini is the more focused choice when a shorter wraparound band matters most.
• mojawa Run Plus Bone: Its biggest strength is the combination of 32GB of offline MP3 storage and an IP68 rating for swimming; its trade-off is that the available controls can fail to operate optimally when the product is wet.
• Shokz OpenRun Mini Bone: Its biggest strength is a band 21 mm shorter than the standard OpenRun size for a more stable fit on smaller heads; its trade-off is that it is not suitable for swimming.
• Both have an open-ear, bone-conduction design and up to eight hours of listening, but only the Run Plus has built-in MP3 storage.
• Choose mojawa Run Plus Bone for swim sessions, offline listening, or a longer feature list.
• Choose Shokz OpenRun Mini Bone if a compact fit for a smaller head is your priority and you mainly listen during land-based workouts.
The Run Plus is the more versatile option in this comparison. Its open-ear bone-conduction design leaves the ear canals unobstructed, so it suits someone who wants audio while remaining aware of nearby sounds. For a kid using headphones on a walk, during a workout, or around the house, that design may be a more suitable starting point than earbuds that sit inside the ears. It still isn’t a substitute for adult supervision or attention to traffic and other hazards.
Its standout feature is the 32GB built-in MP3 player. You can store music or audiobooks on the headphones and listen without a Bluetooth connection. That could be handy for a swim or a phone-free activity. The Run Plus is rated IP68, with submersion specified up to two meters for up to two hours. For swimming, the guidance is to disconnect Bluetooth, switch to MP3 mode, and disable the touchpad. Wet conditions may interfere with operation, so the hands and device should be dry when using the controls.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Battery life is listed as up to eight hours at 75% volume, and a five-minute quick charge is specified to add up to 80 minutes of playtime. The trade-off is that it has no headphone jack, so it won’t work as wired earbuds 3.5mm jack headphones. I’d skip it if wired listening is essential, or if the child needs controls that are straightforward to use with wet hands. Its feature set is compelling, but a parent should think through how the MP3 files will be managed and how the controls will be handled before swim practice.
The OpenRun Mini is the more focused choice for a smaller head. Its wraparound band is 21 mm shorter than the standard OpenRun band, and the stated purpose is a more stable fit on smaller heads. That makes it worth considering for a kid who finds standard wraparound headphones too loose. The open-ear bone-conduction design also leaves the ears open to surrounding sound, which can be useful for running and cycling where awareness matters.
For everyday workouts, the Shokz offers up to eight hours of listening and a quick-charge feature that provides up to 1.5 hours after a 10-minute charge. It has an IP67 water-resistance rating for sweat and workouts, but it is explicitly not suitable for swimming. It connects over Bluetooth, so a phone or another compatible Bluetooth device is needed for wireless listening; there is no built-in MP3 player listed. That is a meaningful limitation for pool use or any outing where carrying a connected device is inconvenient.
The Mini includes a sports headband, carrying case, and magnetic charging cable. It is the simpler fit-first option, rather than the feature-heavy one. I’d skip it if offline playback or swimming is a requirement. And while shoppers may search for on ear headphones for audiophiles, neither of these is a conventional over-ear or on-ear design: both use bone conduction and leave the ear open. Their appeal is situational awareness and workout practicality, not an enclosed listening experience.
