• mojawa Run Plus Bone — biggest strength: IP68 waterproofing plus a built-in 32GB MP3 player, so it works with no phone at all and can be worn swimming. Biggest trade-off: a heavier build (0.31 kg listed) and button controls that the manual says should be kept dry before you swim or operate them.
• SHOKZ OpenRun Bone Conduction — biggest strength: a featherweight 26.4 g wraparound frame with titanium in the build, 8th-gen bone conduction and a simple open-ear fit that basically disappears on your head. Biggest trade-off: IP67 only, and the brand explicitly says it is not suitable for swimming.
• Both run about 8 hours per charge and both use bone conduction drivers with an 8–8.5 ohm impedance and a 20Hz–20,000Hz range.
• Who mojawa Run Plus Bone is for: swimmers, offline-music listeners and anyone who wants one headset for the gym, the pool and the commute.
• Who SHOKZ OpenRun Bone Conduction is for: runners, cyclists and desk workers who live in voice calls and want the lightest possible open-ear fit.
The Run Plus is the more ambitious of the two. Mojawa built in a 32GB MP3 mode that stores roughly 8,000 songs or audiobooks, which means you can leave your phone in a locker and still have hours of audio. That single feature changes how you use the product: it stops being a phone accessory and starts being a standalone player. For anyone who has ever wrapped a phone in a waterproof pouch just to swim laps, that matters.
The waterproofing is the headline spec. IP68 means it is rated to survive submersion in up to 2 meters of water for up to 2 hours, and the brand's own guidance is to disconnect Bluetooth and switch to MP3 mode before swimming, then disable the touchpad. That is a real workflow you have to learn, and it is the honest trade-off: this is not a set-and-forget pool headphone. Mojawa also warns that wet hands or a wet unit can cause the controls to misbehave, and that you should rinse it with fresh water after saltwater exposure.
Buy it if you swim, want offline music, or want one headphone for sport and calls. Skip it if you want the lightest possible frame, or you do not want to manage a dry-hands, dry-unit routine before getting in the water. Note that the noise control field is listed as "None" — the ENC work happens on calls, not as active noise cancellation for listening.
SHOKZ OpenRun Bone Conduction: Who It's For
The OpenRun is the classic execution of the category, and the spec sheet shows why. At 26.4 g with a wraparound frame built from plastic, silicone and titanium, this is a headphone you are meant to forget you are wearing. The blue colorway is clean, and the package includes a carrying bag, a USB-C cable, a sports sweat headband and safety cards — a bundle that tells you the intended buyer is a runner or cyclist, not a swimmer.
That intent shows up in the water rating. The OpenRun is IP67, which the brand describes as sweat-proof and waterproof for workouts, fitness and running. It also includes a moisture detection alert so the headphone will not charge while wet. But SHOKZ states plainly that it is not suitable for swimming. If laps are part of your week, that line alone settles the comparison.
The 8th-generation bone conduction driver transmits through the cheekbone, and the impedance is 8.5 ohm with 105 dB sensitivity across a 20Hz–20,000Hz range. Call quality is a stated priority, and the controls cover call control and volume. Bluetooth range is listed at 9 meters, and the brand notes universal compatibility across Android, iOS and Windows. Battery is 8 hours, and a 10-minute quick charge gets you up to about 1.5 hours. Full charge takes 90 minutes. Two-year warranty, same as the mojawa.
Buy it if you run or ride, want the lightest open-ear frame, and care most about staying aware of traffic while taking calls. Skip it if you need swimming, want built-in storage, or want a phone-free listening mode. Like the mojawa, noise control is listed as "None" — open-ear design is the point, not isolation.
• Best for swimming → mojawa Run Plus Bone. IP68 with a 2-meter, 2-hour submersion rating versus IP67 that the brand says is not for swimming.
• Best for offline listening → mojawa Run Plus Bone. 32GB of onboard MP3 storage for roughly 8,000 tracks or audiobooks.
• Best for all-day light fit → SHOKZ OpenRun Bone Conduction. 26.4 g with a titanium-and-silicone wraparound frame.
• Best for clear voice on calls → SHOKZ OpenRun Bone Conduction, in my opinion, because call control is a named design focus with 105 dB sensitivity and a stated universal-compatibility stance.
• Best for call clarity in noisy places → mojawa Run Plus Bone. Its ENC noise reduction and dual silicone microphone exist specifically to lift voice pickup in background noise.
• Best for a quick top-up → mojawa Run Plus Bone. Five minutes adds about 80 minutes, versus 10 minutes for about 1.5 hours on the OpenRun.
• Best for a low-latency, low-hassle meeting setup → SHOKZ OpenRun Bone Conduction. A light open-ear frame you can wear for long calls without ear fatigue; if you specifically want low latency over ear headphones for meetings, the simpler the connection path the better, and the OpenRun keeps things minimal.
• Best for a single do-it-all headphone → mojawa Run Plus Bone. Swim, gym, runs and calls from one device.
If I were buying one of these, I would pick mojawa Run Plus Bone. The IP68 rating and the 32GB MP3 mode are capabilities the OpenRun simply does not have, and for meetings the ENC noise reduction plus dual silicone microphone is aimed at exactly the problem I care about — being heard clearly when there is background noise. Eight hours of battery on both is a wash, and the quick charge favors the mojawa.
The OpenRun is the better pure running headphone, and if you never swim and want the lightest frame on your head, that is still a defensible choice. But for one headphone that covers sport, meetings and the pool, my money goes to the Run Plus.
mojawa Run Plus Bone. It carries an IP68 rating and is designed to be submerged in up to 2 meters of water for up to 2 hours. SHOKZ states the OpenRun is not suitable for swimming.
Only the mojawa Run Plus Bone works without a phone. Its 32GB MP3 mode stores roughly 8,000 songs or audiobooks offline. The SHOKZ OpenRun relies on Bluetooth (listed range about 9 meters) for all audio.
SHOKZ OpenRun Bone Conduction at 26.4 g, with a wraparound titanium frame. The mojawa Run Plus Bone is listed at 0.31 kg, so the OpenRun is the lighter wear over long stretches.
Neither data sheet lists pricing, so check the current price on Amazon before deciding. In my opinion the mojawa Run Plus Bone is the better value if you swim or want offline storage, since those are features you cannot add later. If you only run and take calls, the OpenRun's lighter build may suit you better for the money.
