How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a gym headphone that survives real sweat, rain and even a pool session while keeping you aware of everything around you, choose mojawa Run Plus Bone; if you need maximum battery life and the newest Bluetooth available in an open-ear bone conduction design, choose Monster Open Ear BC300.
• mojawa Run Plus Bone — biggest strength: a genuine IP68 rating that tolerates submersion in up to 2 meters of water for 2 hours, plus a 32GB offline MP3 mode so you can leave the phone in the locker.
• mojawa Run Plus Bone — biggest trade-off: 8 hours of playtime at 75% volume is respectable but shorter than the Monster, and the touchpad has to be disabled before swimming, so there's a small ritual before you get in the water.
• Monster Open Ear BC300 — biggest strength: 10 hours of battery life paired with Bluetooth 6.0, which is the newer wireless standard of the two.
• Monster Open Ear BC300 — biggest trade-off: its IPX8 rating is described as resisting heavy sweat, rain and temporary submersion, which is worded less specifically than mojawa's 2-meter/2-hour claim, and it ships with just a user manual in the box.
• Who each pick is for: mojawa for swimmers and gym-goers who want a proven submersion rating and offline storage; Monster for long-session athletes who want the longest runtime and the latest Bluetooth.
The Run Plus is built around one idea: keep your ears open and keep going, even when things get wet. The open-ear, bud-free design sits outside the ear canal, so traffic, gym announcements and your training partner's voice all come through while your music plays. For anyone lifting, rowing or running on a treadmill, that awareness matters more than isolation.
What separates it from most open-ear options is the water story. The IP68 rating means it can be submerged 2 meters deep for up to 2 hours, and the brand explicitly frames swimming as a use case — disconnect Bluetooth, switch to MP3 mode, disable the touchpad, and you're set. The 32GB of built-in storage holds a large offline library, so you're not tethered to a phone at the pool or on a trail with no signal. Charging is quick too: a full charge takes about 50 minutes, and a 5-minute top-up adds roughly 80 minutes of playback, which is the kind of thing that saves you when you realize you forgot to charge before a session.
Sound is handled by a bone conduction driver with a 20Hz–20,000Hz range and an 8-ohm impedance, with the brand's physical bass-strengthening approach and dual suspension anchor system doing the heavy lifting on low end. Bluetooth 5.2 covers the wireless side with a 10-meter range, and there's ENC noise reduction for calls. The fit is designed to play nicely with helmets and glasses, which is a real consideration if you cycle or ski.
Monster Open Ear BC300: Who It's For
The BC300 takes the same open-ear, bone-conduction-through-the-cheekbones concept and leans into endurance. The headline number is 10 hours of playtime — two hours more than the mojawa — which is the difference between charging every couple of days and charging almost daily if you train a lot. For long rides, back-to-back gym sessions or full outdoor days, that headroom is genuinely useful.
It also runs Bluetooth 6.0, the newer wireless version here, which the brand pitches as stable and low-latency for streaming and calls. There's environmental noise cancellation on board for voice pickup. Like the mojawa, it carries 32GB of built-in memory, so you can load thousands of songs and go phone-free for swimming, running or gym work.
The waterproofing is rated IPX8, described as resisting heavy sweat, rain and temporary submersion — solid for intense training and all-weather use, though the wording stops short of mojawa's explicit 2-meter depth and 2-hour duration. The color option listed is an orange finish, and the package includes the headphones and a user manual, with a 2-year warranty noted.
Buy it if you want the longest battery life, the newest Bluetooth, and an open-ear design for cycling, running and gym work. Skip it if you specifically need a stated depth-and-duration submersion rating, or if you want a carry case and cable included.
Side-by-Side: Which Should You Choose?
• Best for swimming with a stated depth rating → mojawa Run Plus Bone. IP68 with 2 meters for 2 hours is the more concrete claim.
• Best for the newest wireless standard → Monster Open Ear BC300. Bluetooth 6.0 beats Bluetooth 5.2 on paper.
• Best for gym sessions where you leave the phone behind → tie. Both offer 32GB of built-in storage for offline playback.
• Best for quick top-ups → mojawa Run Plus Bone. A 5-minute charge adds about 80 minutes, and a full charge takes roughly 50 minutes.
• Best for call clarity features → both. mojawa lists ENC noise reduction; Monster lists environmental noise cancellation.
• Best for cycling with a helmet or glasses → mojawa Run Plus Bone. Its ergonomics are explicitly designed to fit with helmets and glasses.
• Best for what's in the box → mojawa Run Plus Bone. It includes a cable and carry bag; the Monster ships with the manual.
In my opinion, the mojawa Run Plus Bone is the better pick for most gym-focused buyers. The combination of an IP68 rating with a stated depth and duration, a fast-charge system that rescues you before a workout, offline 32GB storage and a fit designed around helmets and glasses makes it the more versatile training tool. I'd choose the Monster Open Ear BC300 only if runtime is the deciding factor for you — 10 hours and Bluetooth 6.0 are real advantages for long outdoor sessions and frequent users who hate charging. For everyone else sweating it out indoors, mojawa wins on the details that matter.
