*Tested at the Shokz Lab under controlled conditions at 25 ± 2 °C with a standard power adapter. A 10-minute charge in the charging case delivers the earbud approximately 4 hours of music playback, based on AAC-encoded audio played at 50% volume with Noise Reduction and other special audio features turned off. Actual performance may vary depending on device settings, volume level, audio source, environmental interference, features enabled, usage habits, and other factors.
*Shokz OpenFit Pro features AI noise reduction technology designed to reduce environmental noise while preserving human voices. Internal simulations conducted by Shokz Lab suggest that this technology can achieve a signal-to-noise ratio improvement of approximately 42 dB, corresponding to a potential 99.4% reduction in ambient noise, along with effective reduction of loud echoes. Note that actual performance may vary depending on environmental conditions.
*Tested at the Shokz Lab. This total listening time represents the cumulative playback achieved from a fully charged set of earbuds and a fully charged charging case. The playback test was conducted in a temperature-controlled environment of 25 ± 2 °C, playing AAC-encoded audio at 50% volume, with Noise Reduction and other special audio features turned off. Actual battery life may vary depending on device settings, volume level, audio source, environmental interference, features enabled, usage habits, and other factors.
*IP55 water-resistance only applies to the earbuds, and charging case is not rated waterproof. OpenFit Pro is resistant to sweat and water splashes, suitable for non-aquatic sports and activities. Under specific testing conditions, its waterproof performance has reached the IP55 level based on the IEC 60529 standard. The sweat and waterproof capability is not permanent and may decrease over time due to wear and tear. DO NOT charge a wet OpenFit Pro, nor swim or shower with it.
*In a 25°C environment with 2W charging power, this device was tested to reach a full charge in 3 hours with a wireless charger. The OpenFit Pro's charging case is compatible with all Qi-certified wireless chargers. Actual charging time may vary depending on charger specifications, ambient temperature, usage conditions, and other factors.
*Internal testing conducted by Shokz Lab using a low-noise fan to create a stable wind noise environment, with the headset worn on a speaking artificial head to test call quality at 15 km/h in an anechoic chamber. However, real-world conditions may vary, and wind noise reduction may be less effective in different environments.
