How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a rugged, swim-ready open-ear headphone with built-in music storage and no phone required, choose mojawa Run Plus Bone; if you need a light, hook-on true-wireless pair for all-day comfort, calls, and a pocketable charging case, choose Shenzhen SHOKZ OpenFit Air.
• mojawa Run Plus Bone — biggest strength: IP68 waterproofing plus a real 32GB MP3 player, so you can swim or train with zero device nearby.
• mojawa Run Plus Bone — biggest trade-off: It's a single wrap-around headband with button controls, no charging case, no companion app, and touch controls you're told to disable before swimming.
• Shenzhen SHOKZ OpenFit Air — biggest strength: Feather-light earhooks (0.3 oz per bud), 4 smart mics, multipoint pairing to two devices, and 28 hours of total playtime via the case.
• Shenzhen SHOKZ OpenFit Air — biggest trade-off: Only IP54 water resistance, so sweat and splashes are fine but swimming is not.
• Who each pick is for: The mojawa for swimmers, rain runners and phone-free athletes; the OpenFit Air for commuters, office and driving use, and anyone who wants an app to tune their sound.
The Run Plus is built around one idea: keep your ears open and your phone in the locker. It uses a bone conduction driver with a frequency range of 20 Hz to 20,000 Hz, paired with Mojawa's Maglev-Bass actuator and Dual Suspension Anchor System, so the low end is pushed through your cheekbones rather than sealed into your ear canal. If you've ever run a road route and wanted to hear traffic, this is the whole point of the design.
The standout spec is the combination of IP68 waterproofing and 32GB of on-board storage. That's a claimed tolerance of submersion to 2 meters for up to 2 hours, and roughly 8,000 songs or audiobooks held offline. In practice that means you can leave your phone on the pool deck, switch to MP3 mode, and swim laps with nothing but the headband. Battery is rated at 8 hours at 75% volume, and a 5-minute quick charge buys about 80 minutes — enough to rescue a session you forgot to charge. A two-year warranty and a silicone build rated to fit under helmets and glasses round it out.
Who should buy it: swimmers, open-water and pool lap users, rainy-day runners, and anyone who wants music without carrying a phone. Who should skip it: if you mostly take calls all day, want app-based EQ, or want a case that recharges on the go, this isn't the design for you. Also worth knowing — the touchpad is meant to be disabled in the water, and wet hands can affect operation, so it's a headphone you operate dry and then get wet.
The OpenFit Air takes the opposite approach. Instead of a headband, it's a true-wireless pair of earhooks that sit above each ear and pivot back until they're snug. Each bud weighs about 0.3 oz, and the enclosure mixes nickel-titanium alloy, plastic and silicone — a combination that explains the wobble-free fit without clamping your skull. The angular shape with ear hooks is what keeps them planted during a run or a yoga session.
Sound comes from Shokz DirectPitch tuning holes, which aim for natural audio with minimal leakage and honest bass while leaving your ears completely open. Four smart microphones handle voice pickup, and multipoint pairing lets you hold two connections at once — laptop and phone, for example — then hop between them with a tap. Battery is 6 hours per charge, 28 hours with the case, and a 10-minute top-up gives roughly 2 extra hours. The 33-foot Bluetooth range and app support for EQ modes, button customization and power readouts make it the more "connected" of the two.
The honest limitation is IP54. That's splash and sweat resistance, not swimming. It also uses an impedance of 17 ohm with a 20 Hz to 15,000 Hz range, so the treble ceiling is lower than the mojawa's on paper.
Who should buy it: commuters, desk workers, drivers, gym-goers and casual listeners who want something they can forget they're wearing and drop into a case afterwards. Who should skip it: swimmers, and anyone who wants to train without a phone, because everything here depends on a Bluetooth source.
• Best for swimming → mojawa Run Plus Bone. IP68 with 2m/2h submersion versus IP54 splash resistance. This one isn't close.
• Best for phone-free workouts → mojawa Run Plus Bone. The 32GB MP3 mode is the feature the OpenFit Air simply doesn't have.
• Best for all-day comfort → Shenzhen SHOKZ OpenFit Air. 0.3 oz per earhook versus a full wrap-around headband; the hooks disappear on your head in a way a band never does.
• Best for calls → Shenzhen SHOKZ OpenFit Air. 4 smart mics and multipoint pairing to two devices, versus the mojawa's dual silicone mic with ENC on a single Bluetooth 5.2 link.
• Best total battery → Shenzhen SHOKZ OpenFit Air. 28 hours with the case beats 8 hours on a single charge, even though the mojawa wins the quick-charge contest (5 min for 80 min versus 10 min for 2 hours).
• Best for helmets and glasses → mojawa Run Plus Bone. It's explicitly ergonomically shaped to sit under a helmet and around glasses frames.
• Best for tuning your sound → Shenzhen SHOKZ OpenFit Air. The app gives you EQ modes and customizable buttons; the mojawa gives you physical buttons and nothing to install.
• Best for rain and rough weather → mojawa Run Plus Bone. IP68 covers getting caught in a downpour; IP54 is a splash rating.
• Best for travel and storage → Shenzhen SHOKZ OpenFit Air. A compact charging case you can pocket, versus a carry bag and cable for the headband.
If I had to pick one for myself, I'd take the mojawa Run Plus Bone. The IP68 rating and 32GB of offline storage solve a problem nothing else here solves — training hard, in water or weather, with no phone in the equation — and the fact that it charges in 5 minutes for 80 more minutes of play is exactly what I'd want on a rushed morning.
That said, I'd only recommend it if your life involves water or you genuinely want to leave the phone behind. If your days are commutes, calls and desk work, I'd point you at the Shenzhen SHOKZ OpenFit Air instead: lighter on the head, smarter on calls, and the case keeps it topped up for nearly a week of ordinary use. Check the current price on Amazon for both before you decide — the gap between them is smaller than the gap in what they're built to do.
FAQ

how to wear bone conduction headphones
Place the transducer pads against your cheekbones just in front of each ear and run the band around the back of your head. The Run Plus is shaped to sit comfortably under a helmet and around glasses, and the OpenFit Air's earhooks are worn by placing each bud above the ear and pivoting it backward until it's snug.
how to use bone conduction headphones
Charge them, pair over Bluetooth, and press play — that's the standard flow for both. The Run Plus adds a second mode: load songs onto its 32GB player and switch to MP3 mode, which is what you'd do before swimming (disconnect Bluetooth and disable the touchpad first). The OpenFit Air adds app control for EQ, buttons and multipoint pairing.
Only the mojawa Run Plus Bone is. Its IP68 rating covers submersion in up to 2 meters of water for 2 hours, and it has the offline MP3 mode you need with no phone nearby. The Shenzhen SHOKZ OpenFit Air is rated IP54, which handles sweat and splashes but not swimming.
