If you want a proven open-ear sport headphone built around bone conduction with a secure running-first fit, choose Amazon Renewed SHOKZ; if you need true underwater listening with onboard storage and a higher waterproof rating, choose LOBKIN Bone Conduction &.
• Amazon Renewed SHOKZ — biggest trade-off: it's a renewed unit with a 90-day limited warranty, and its sweat resistance is aimed at workouts, not submersion, so pool swimming is off the table.
• LOBKIN Bone Conduction & — biggest strength: IP68 waterproofing with a triple-sealed body and 32GB of built-in storage, so you can swim with music and leave your phone behind.
• LOBKIN Bone Conduction & — biggest trade-off: shorter 10-hour battery life, a 2-hour charge time, and a plastic build that feels more utilitarian than premium.
• Who each is for: pick the SHOKZ if you run, lift or cycle and want the most polished open-ear experience; pick the LOBKIN if the pool is your main training ground and you want offline playback.
The SHOKZ OpenRun Pro 2 is the more refined piece of hardware here, and the spec sheet shows why. It pairs two driver types — bone conduction for the highs and air conduction for the low end — into what the brand describes as 3D audio across a 20 Hz to 20,000 Hz range. That's a genuinely wide frequency window for an open-ear design, and it's the reason this model is usually talked about as a sport headphone that doesn't sound thin. The unibody frame uses a Ni-Ti alloy memory wire in the ear hooks, which is the classic recipe for a fit that resists slipping when you sweat or move your head. At roughly 30 grams it's light enough to forget about on a long run.
Where it pulls ahead for athletes is the small stuff. There are two EQ modes through the companion app: a Classic Mode that leans into pure bone conduction, and a Volume Boost Mode for noisy environments like a busy road or a loud gym. The dual wind-resistant microphones plus AI noise reduction are rated to filter out 96.5% of background noise, including wind up to 15 mph — a real consideration if you take calls mid-ride. Battery life is 12 hours with a 1-hour charge, and controls are touch-based volume. Sweat resistance and open-ear awareness are the headline safety features: you hear traffic and training partners while your audio stays private to you.
LOBKIN Bone Conduction &: Who It's For
The LOBKIN X39 is built around one clear idea: music in the water, no phone required. It combines bone conduction and air conduction drivers the same hybrid way the SHOKZ does, but the headline spec is IP68 waterproofing with a triple-sealed structure. That's a meaningful jump over sweat resistance — it's rated for submersion beyond 1.5 meters, and the brand is explicit that you switch to MP3 mode underwater because Bluetooth won't connect through water. That onboard 32GB of storage holds up to 8,000 songs, and you load them over the magnetic charging cable. For a swimmer, that's the whole ballgame: laps with your own playlist and nothing strapped to your arm.
The rest of the spec sheet is aimed at comfort and convenience. It weighs 25 grams, lighter than the SHOKZ, and uses skin-friendly liquid silicone so it sits under a swim cap, goggles or a helmet. Bluetooth 6.1 is the newer wireless standard here, with a stated 15-meter range, and ENC noise cancellation plus a windproof mic handles calls on land. Battery life is 10 hours with a roughly 2-hour magnetic charge. Controls are physical push buttons rather than touch — a small but real advantage with wet hands. You also get a fuller accessory kit out of the box: foam ear tips, a silicone neck strap, a protective case, the magnetic cable and a manual.
Who should buy it? Swimmers, surfers, snorkelers and anyone who wants offline playback without carrying a phone. It's also a sensible pick for teens and adults who want a rugged, cheap-to-replace-feeling training headphone. Who should skip it? If your priority is the most natural, bass-rich sound for running and you never get in the water, the SHOKZ's tuning and app EQ give you more to work with. The LOBKIN's ABS and polycarbonate body and 12-month warranty tell you it's a value-focused tool, not a premium one. As always, check the current price on Amazon rather than assuming.
Side-by-Side: Which Should You Choose?
• Best for swimming → LOBKIN Bone Conduction &. IP68 waterproofing and MP3 mode are the deciding factors; the SHOKZ isn't rated for submersion.
• Best for running and cycling → Amazon Renewed SHOKZ. The memory-wire ear hooks, 12-hour battery and wind-resistant mics suit road and trail work better.
• Best for call quality on the move → Amazon Renewed SHOKZ. AI noise reduction rated to cut 96.5% of background noise, including wind up to 15 mph, is the more advanced mic setup on paper.
• Best for sound customization → Amazon Renewed SHOKZ. Two app EQ modes (Classic and Volume Boost) versus the LOBKIN's fixed tuning.
• Best for long sessions on one charge → Amazon Renewed SHOKZ. 12 hours versus 10, and it tops up in 1 hour instead of 2.
• Best for wet-hand control → LOBKIN Bone Conduction &. Physical push buttons beat touch controls when your fingers are wet or gloved.
• Best for warranty peace of mind → LOBKIN Bone Conduction &. A 12-month warranty against the SHOKZ's 90-day limited renewed coverage.
If I had to pick one, I'd buy the LOBKIN Bone Conduction & for a swimmer and the Amazon Renewed SHOKZ for everyone else — but forced to choose a single pair for myself, I'd take the SHOKZ. In my opinion, the dual-driver tuning, the memory-wire fit, the app EQ modes and the 12-hour battery make it the more complete everyday headphone for land training, and the mic system is a clear step up. The catch is that it's renewed with a 90-day warranty and it can't go in the pool. If swimming is your main sport, that trade flips instantly and the LOBKIN wins. Check the current price on Amazon for both before you commit.
how to bone conduction headphones work
Bone conduction drivers vibrate against your cheekbone and pass sound to your inner ear, bypassing the eardrum. Both models here actually blend bone conduction with air conduction drivers for fuller sound. The key benefit is that your ear canal stays open, so you keep hearing your surroundings.
how to wear bone conduction headphones
Hook the earpieces over the tops of your ears and rest the transducers against your cheekbones, just in front of your ears. The SHOKZ uses a Ni-Ti memory-wire frame for a secure fit; the LOBKIN's 25-gram silicone build is designed to sit under a swim cap, goggles or helmet. Neither goes inside your ear canal.
how to use bone conduction headphones
Pair over Bluetooth for normal listening and controls — touch volume on the SHOKZ, push buttons on the LOBKIN. For swimming, the LOBKIN must be switched to MP3 mode, because Bluetooth won't transmit underwater. Load songs onto its 32GB storage via the magnetic cable first.
how to bone conduction headphones for swimming
Only the LOBKIN is rated for it, thanks to IP68 waterproofing and a triple-sealed body. Switch to MP3 mode, play your downloaded tracks, and rinse the headphones after each swim. The SHOKZ is sweat resistant, not submersible, so keep it out of the pool.
