Run Safely.
Hear Everything. Sound Like Nothing Before.
Bone conduction headphones finally solved the bass problem. DualPitch™ pairs a bone conduction transducer (precise mids and highs) with a dedicated air conduction speaker (deep bass) — delivering full-spectrum audio while your ears stay completely open to traffic, trail sounds, and your surroundings. 12 hours battery. 5-minute charge gives 2.5 hours. USB-C. IP55. Bluetooth 5.3. AI dual mic filters 96.5% of background noise.
The Bone Conduction Problem Is Solved.
Bass Is No Longer the Trade-Off.
For over a decade, bone conduction headphones made one unavoidable trade-off: open-ear safety for audio quality, specifically bass. The technology works by bypassing the ear canal entirely — vibrations travel through the cheekbones to the cochlea — which produces excellent mids and highs but structurally struggles with low frequencies. Bass requires the large air pressure waves that ear canal sealing creates. Without sealing the ear, achieving the bass response that makes training music compelling was impossible. Every runner who loved the safety of bone conduction lived with the thinner, tinnier sound of that compromise.
DualPitch™ ends the trade-off. A dedicated air conduction speaker is positioned adjacent to the ear canal opening — not blocking it, but directing bass frequencies through conventional acoustic air pressure directly at the open ear. The bone conduction transducer handles mids and highs; the air conduction speaker handles bass. Ultra Running Magazine reviewed four consecutive generations and confirmed: "The most noticeable improvement in sound quality is richer overall bass tones. The dual speaker configuration virtually eliminates the vibrations — there is almost no vibratory sensation against your skin, even with rock music cranked at top volume." SoundGuys: "cream of the crop when it comes to bone conduction headphones."

Both Safer and More Enjoyable.
Each upgrade in the OpenRun Pro 2 addresses a specific criticism of previous bone conduction headphones — from bass quality to battery anxiety to charging compatibility to call clarity on the run.
DualPitch™ — Bone Conduction Mids/Highs + Air Conduction Bass, Simultaneously
Two physically distinct drivers operating simultaneously in their respective frequency domains. The bone conduction transducer is positioned against the cheekbone — its mechanism is physical skull vibration. It excels at the frequency range where vocal intelligibility and melodic content live: midrange (300Hz–3kHz) and high frequencies (3kHz+). The air conduction speaker is directed toward the open ear canal but does not block it. It delivers bass frequencies (below 300Hz) through conventional acoustic air pressure — the same fundamental mechanism as any speaker, but without the ear canal seal. This means: music sounds full, not thin. Bass-heavy training genres (hip-hop, EDM, heavy rock) actually sound like bass-heavy music. Ultra Running Magazine, after testing four consecutive Shokz generations: "The dual speaker configuration virtually eliminates the vibrations of many bone conduction headphones. There is almost no vibratory sensation against your skin, even with rock music cranked at top volume." The Shokz DirectPitch™ algorithm optimises the angle and distance between the air conduction speaker and the ear canal for each frequency band, maximising delivery efficiency.
12 Hours + 5-Minute Fast Charge + USB-C — Three Battery Problems Solved at Once
Three distinct battery improvements, each solving a different pain point. 12-hour battery life (up from 10 hours on the Pro 1): Ultra Running Magazine real-world tested "14 or 15 hours at moderate volume" — the spec is conservative. This covers a full marathon, an ultra-distance training day, or three weeks of typical 45-minute daily runs without charging. 5-minute fast charge delivers 2.5 hours: Ultra Running Magazine confirmed "if you forget that the headphones are dead just as you're heading out the door, a 5-minute charge provides 2.5 hours of life to get through a workout." This is the "I forgot to charge" safety net. USB-C charging: the previous-generation Pro 1 used a proprietary 2-pin magnetic cable that required carrying a unique cable — the Pro 2 charges via the same USB-C cable as your phone, laptop, and wireless earbuds. SoundGuys: "I also appreciate that Shokz upgraded the charging port from the 2-pin connector of old to a USB-C charging port. This finally brings the company's flagship models into the modern age."
Open-Ear Situational Awareness + Reflective Strip — Built for Road and Trail
The fundamental safety case for bone conduction over in-ear earbuds: the ear canal remains completely open. There is no seal, no isolation, and no acoustic barrier between you and your environment. Traffic sounds, cyclist warnings, pedestrian conversations, and trail surface changes are audible at full natural volume simultaneously with whatever audio is playing through the transducers. SoundGuys: "My favourite thing about the OpenRun Pro 2 is how they keep me aware of my surroundings while allowing me to hear my media. This environmental awareness is invaluable as I move through the city." T3's reviewer: running without headphones was his baseline before testing — the open-ear awareness converted him. The reflective strip on the headband is the second safety layer: visible to headlights and bike lights during night running and pre-dawn training, making the runner visible from both sides and the front. For road runners who train early mornings or after dark, the reflective strip is the difference between being visible and being invisible at car headlight range.
16% Less Clamping Force · CoreCushion · Ni-Ti Frame — Wear It for Hours
Three comfort improvements over the previous generation. 16% reduction in clamping force (Shokz internal measurement): the previous Pro 1 required enough cheekbone contact pressure that multi-hour sessions accumulated discomfort. The Pro 2's reduced clamping achieves secure positioning with less sustained pressure. CoreCushion — the silicone-coated contact pad between the transducer and cheekbone — distributes the remaining contact pressure across a 4° expanded contact area rather than concentrating it at a single point. The combined effect: Ultra Running Magazine, after testing all four generations, confirmed it as their "go-to for training and racing." Ni-Ti alloy memory wire frame: titanium-based shape-memory alloy that stores its shape and returns to it after being bent, compressed, or stuffed in a bag. SoundGuys confirmed: "The titanium headband is bendy and springy as ever, making it easy to stuff the headphones into my gym bag or pocket." Standard size fits head measurements over 9.25" (measured ear to ear over the back of the head).
Dual AI Microphones · 96.5% Noise Reduction · 25km/h Wind-Proof Calls
Taking phone calls while running has historically meant the caller hearing wind, traffic, and footfalls more than the runner's voice. The Pro 2's dual microphone architecture uses AI noise reduction to filter 96.5% of background noise from voice calls, with physical placement in the optimal low-wind zone of the frame and internal baffling that redirects wind around the microphone capsule. Confirmed wind-resistant call clarity up to 25km/h — the speed range of most runners, most of the time. Ultra Running Magazine: "strategically placed voice capture microphones that provide speech clarity in windy conditions up to 15 mph." Two physically separated microphone positions enable directional noise filtering — the AI algorithm identifies the primary voice source and suppresses audio from all other directions. For active commuters who take calls mid-run, coaches who need to communicate while running alongside athletes, and anyone who wants to stay reachable during training without stopping — this is functional, not aspirational.
Three Athletes Who Need to Hear
Both Their Music and Their World.
The OpenRun Pro 2 specifically serves athletes for whom situational awareness is not optional — and who previously had to choose between music and safety.
Road running with standard in-ear earbuds creates a genuine safety hazard: sealed ear canals produce measurable delays in traffic awareness response. In some jurisdictions, it is illegal. Bone conduction eliminates the seal — you hear traffic, cyclists, and pedestrians at full natural volume while music plays through the transducers. The DualPitch™ bass improvement means running to bass-heavy motivation music no longer requires the sonic compromise that made some runners reluctant to use bone conduction. The reflective strip makes night running and dawn-patrol training safer by ensuring visibility at car headlight distance. Ultra Running Magazine, after four generations: "the OpenRun Pro 2 is our go-to for training and racing." The 12-hour battery outlasts marathon training long runs and back-to-back training days without charge management.
Cycling with in-ear earbuds is illegal in numerous jurisdictions and broadly considered dangerous — full ear sealing at cycling speeds creates hazardous delays in traffic response time. Bone conduction is the legally compliant alternative: the ear canal remains open, traffic sounds are fully audible, and music plays without isolation. The DualPitch™ bass improvement specifically matters for cyclists covering long distances where audio quality sustains motivation — previous bone conduction sounded too thin for multi-hour rides. IP55 rain and sweat resistance handles wet roads. The titanium Ni-Ti frame sits securely under cycling helmets. T3's reviewer ran and cycled with the Pro 2 for two months: "a fantastic option for runners, cyclists, and outdoor enthusiasts who want a balance of immersive audio and safety."
Gym environments require awareness: trainers giving cues, equipment sounds signalling machine availability, other athletes approaching. Sealed earbuds create an isolation bubble that many gym users find situationally awkward or socially inappropriate. The Pro 2's open-ear design allows gym floor conversation without removing the headphones. The 16% reduced clamping force makes multi-hour gym sessions comfortable. For anyone who finds in-ear earbuds physically uncomfortable — ear canal pressure after extended wear, sweat-induced slippage, or simple sensory aversion to objects in the ear canal — bone conduction is a genuinely superior format. SoundGuys: "I could definitely use the included carrying case, but frankly, the IP55-rated headphones can withstand just about anything."

The Best Open-Ear Sport Headphone
for Athletes Who Refuse to Choose.
The SHOKZ OpenRun Pro 2 in Black earns its Editor's Pick as the most independently validated open-ear sport headphone available — confirmed by Ultra Running Magazine (four generations tested, Pro 2 is the best), SoundGuys ("cream of the crop"), and T3 ("fantastic option for runners, cyclists, and outdoor enthusiasts"). The Safety score (9.5) is the highest on this page because open-ear design combined with the reflective strip creates a demonstrably safer audio format for outdoor athletes than any in-ear alternative. The Sound score (9.4) reflects DualPitch™'s genuine advance — "virtually eliminating vibrations while delivering richer bass tones" — the most significant audio improvement in the product line's history.
The honest calibration: the air conduction speaker is partially susceptible to direct headwind above 25km/h (Classic Mode workaround). Sound leakage at high volume is inherent to open-ear design, though improved. Not for swimming (IP55 only). Standard size fits head measurements above 9.25" — verify before ordering. Not an audiophile-grade sealed headphone. For road runners, cyclists, gym athletes, earbud-avoiders, and any outdoor athlete who wants to hear both their music and their surroundings — this is the standard.
