Description: The Shokz OpenRun Pro 2 sets a new benchmark for outdoor sports audio by merging premium bone conduction technology with a dedicated air conduction bass driver.

Built with a sweatproof IP55-rated titanium frame and a 12-hour quick-charging battery, these sport headphones are built to endure heavy training conditions. 7. More Details: Designed exclusively to meet the demands of competitive marathoners, trail runners, and outdoor fitness enthusiasts, the Shokz OpenRun Pro 2 delivers an uncompromised balance of safety and acoustic energy. By utilizing innovative Tenth-Generation DualPitch™ Technology, these headphones delegate audio frequencies to two separate drivers: an all-metal bone conduction unit handles clear highs and vocals, while an independent 18x11mm air conduction speaker generates booming, resonant bass. This removes the tickling vibration sensation common in old bone-conduction models while drastically widening the soundstage. Structurally, the unit features a featherlight 30.3-gram titanium alloy frame covered in skin-friendly silicone, ensuring a secure, non-slip fit that will not shift during high-intensity workouts. For elite communication, dual microphones utilize an AI noise reduction algorithm that filters out up to 96.5% of wind and background traffic noise. Complete with a waterproof USB-C port, a 5-minute quick charge feature for 2.5 hours of emergency playback, and robust IP55 water resistance, it offers the ultimate high-performance audio experience for open-road endurance training.
