Secure Over-Ear Fit That Helps Reduce Drop-Out: The wireless earbuds use a pressure-distributed over-ear hook that supports the ear along the outer contour rather than relying on the ear canal. This design helps reduce movement from sweat, head motion, or impact during workouts or extended wear. With S/M/L ear tips, users can adjust fit for stability and comfort. By reducing ear canal pressure, the over-ear structure is more comfortable for users with smaller ears, narrow ear canals, or glasses. Voice-Focused Audio with Practical ENC Support: Featured 13mm dynamic drivers tuned for clear vocals and balanced sound, avoiding exaggerated audio effects. The ENC microphone system helps reduce background noise such as traffic, airflow, or crowd sounds during calls, improving speech clarity for daily use. This makes the noise cancelling earbuds suitable for phone calls, virtual meetings, and voice interactions where being understood matters more than isolation, while maintaining comfort. Stable Connectivity Designed for Multi-Device Use: The wireless headphones uses Bluetooth 5.3 to maintain stable audio connections across phones, laptops, and tablets, making it suitable for users who frequently switch between devices. In signal-dense environments such as gyms or offices, it helps reduce dropouts and interruptions. Hall sensor technology enables automatic reconnection when the case is opened, supporting uninterrupted listening and reliable call performance throughout daily use. Clear Power Visibility for Extended Listening: The Bluetooth earphones offer up to 8 hours of continuous playback per charge, with the charging case extending total usage to approximately 48 hours. Dual LED indicators display real-time battery levels for both the wireless ear buds and the case, keeping power status clearly visible during extended listening or travel. USB-C fast charging restores power efficiently in about 1.5 hours, supporting frequent, repeated use across daily activities. Simple Touch Control Across Devices and Platforms: The earbuds wireless bluetooth feature high-sensitivity touch panels for direct control of music, volume, calls, track switching, and voice assistants. Effortlessly manage audio in libraries, home relaxation, or cafés without touching your phone. These wireless earphones are compatible with iOS, Android, and most Bluetooth devices, enabling seamless switching across smartphones, tablets, and laptops for versatile multitasking. Defined Protection for Active Daily Environments: The Csasan workout earbuds carry an IPX7 protection rating engineered to withstand sweat, rain exposure, and elevated humidity commonly encountered during active daily use. The protective structure is built to maintain durability and stable performance under frequent movement and changing conditions. This level of protection supports everyday reliability, but is not intended for swimming or prolonged underwater use.
