If you want a dedicated swimming-capable MP3 player with deep bass for serious training, choose mojawa Run Plus Bone; if you need a featherweight, secure fit specifically designed for smaller heads or younger athletes, choose Shokz OpenRun Mini Bone.
• mojawa Run Plus Bone: Its standout strength is the IP68 waterproof rating that allows full submersion for swimming, paired with 32GB of built-in storage for offline listening; the trade-off is a heavier build and a design optimized for larger adult ears rather than small ones.
• Shokz OpenRun Mini Bone: This model excels in ultra-lightweight comfort with a Nickel-Titanium frame and a compact size tailored for smaller heads, though it lacks swim capability and relies entirely on Bluetooth streaming without internal storage.
• The Verdict: Pick the mojawa for swimmers and those who hate carrying phones, but choose the Shokz Mini for kids or anyone prioritizing a discreet, lightweight fit during high-movement activities.
The mojawa Run Plus Bone is engineered for the athlete who refuses to compromise between safety and immersion. If your workout routine involves hitting the pool, this is the only device that truly fits the bill. This isn't just splash resistance; it is genuine swim-proofing. However, there is a specific protocol required for water use: you must disconnect Bluetooth and switch to the built-in MP3 mode before entering the water. Once in MP3 mode, the touchpad controls are disabled to prevent accidental inputs from water droplets, ensuring the device functions reliably even when fully wet.
For runners and cyclists, the 32GB of internal storage changes the game. You can load up to 8000 songs or audiobooks directly onto the headphones. This means you can leave your phone at home or in your locker, enjoying a completely wireless experience without relying on a smartphone connection. The device uses Bluetooth 5.2 for gym sessions where you might want to pair with a phone, but the onboard player offers freedom from battery-draining connections. The sound profile is tuned for energy, utilizing a patented Original Physical Bass Strengthen Technology and a Dual Suspension Anchor System. This setup delivers deeper bass than typical bone conduction units, which is crucial for keeping motivation high during intense intervals or long runs.

However, this versatility comes with physical considerations. At 0.31 kg (including the case), it is a substantial piece of gear compared to other options. The earpiece shape is described as "Around-ear or On-ear," suggesting a more robust clamping force designed to stay put during vigorous activity. While the brand notes it fits comfortably with helmets and glasses, the bulkier frame and weight make it less ideal for someone seeking a barely-there sensation. Furthermore, the battery life is rated at 8 hours at 75% volume, which is solid, but the charging time of 50 minutes is longer than some competitors. If you are looking for a device to handle saltwater exposure, you can rinse it after surfing or ocean swimming, but you must dry both your hands and the product before operating it again to ensure optimal performance. This headphone is for the dedicated sports enthusiast who needs durability and storage over minimalism.
The Shokz OpenRun Mini Bone is clearly designed for a different demographic: those with smaller head circumferences or users who prioritize absolute lightness above all else. With a band that is 0.83 inches shorter than the standard model, this headset is built to provide a stable, secure fit for smaller heads, making it an excellent candidate for teenagers or adults with petite frames. The construction utilizes a Nickel-Titanium Alloy frame, which contributes to its incredibly low weight of just 26 grams. This featherlight design ensures that the headphones feel almost invisible while running or cycling, reducing neck strain during long sessions.
In terms of connectivity and usage, this unit operates exclusively via Bluetooth 5.1, offering a seamless pairing experience with Android, iOS, and Windows devices. Unlike its mojawa counterpart, it does not have internal storage, so you will need your phone nearby to stream music or take calls. The audio driver technology is Shokz's 8th generation bone conduction system, which transmits sound through the cheekbone directly to the inner ear. This provides clear audio while leaving the ear canal open, allowing you to hear traffic and surroundings—a critical safety feature for outdoor runners. The IP67 water resistance rating makes it sweat-proof and capable of handling rain, but it is explicitly not suitable for swimming. A moisture detection alert is included to protect the electronics if you attempt to charge a wet device, adding a layer of safety for sweaty workouts.
The battery performance matches the industry standard at 8 hours of continuous playtime, with a quick charge feature that provides 1.5 hours of use from a mere 10-minute charge. The control scheme relies on a combination of button and touch controls, including volume management, which is straightforward for adjusting levels mid-run. The package includes a sports headband, which helps absorb sweat and keeps the device in place, along with a fabric carrying case. This bundle suggests a focus on active lifestyles where hygiene and secure fit are paramount. If you are buying for a child or a user who finds standard-sized headphones too heavy or loose, the Mini's specific dimensions and lightweight alloy frame make it the superior choice. It sacrifices swim capability and onboard storage to achieve a fit that feels custom-tailored for smaller users.

When I look at the specs, the choice boils down to the primary environment of the user. If I were shopping for a kid or a teenager who is still growing, the Shokz OpenRun Mini Bone is the obvious winner. The shorter band and 26-gram weight mean it won't slip off or weigh them down during school sports or casual runs. The fact that it comes with a headband is also a practical touch for managing sweat. However, if I am buying for myself as an adult triathlete or a runner who loves to swim, the mojawa Run Plus Bone is the only logical choice. The ability to submerge it in water and carry my own music library makes it a versatile tool that the Shokz simply cannot match. Ultimately, for the specific use case of a kid, I recommend the Shokz OpenRun Mini Bone because its size and weight are perfectly calibrated for younger users, ensuring they actually wear it comfortably.
Only the mojawa Run Plus Bone supports swimming due to its IP68 rating; the Shokz OpenRun Mini Bone is IP67 rated and not suitable for submersion.
The mojawa Run Plus Bone includes 32GB of internal memory for up to 8000 songs, while the Shokz OpenRun Mini Bone requires a connected smartphone for audio playback.
Yes, the Shokz OpenRun Mini Bone is specifically designed with a shorter band and lighter frame to fit smaller heads securely, whereas the mojawa is sized for adults.
Both models offer approximately 8 hours of continuous playtime, though they differ slightly in their quick-charging capabilities and total charge times.
