The adjustable ear hooks fit perfectly to the natural curve of the ear, so you don't have to worry about them falling out during sports or training. Because they don't completely block the ears, you can clearly hear the surrounding environmental sounds while listening to music. You can always pay attention to the surroundings during sports such as running and jogging, so you can exercise safely and securely. 【Bass Boost with TubeBass Technology, Sound Leakage Suppression】The uniquely developed TubeBass bass enhancement technology, combined with LISO algorithm acoustic technology, can provide a powerful bass effect. Equipped with a large 16.2mm dynamic driver, it achieves immersive sound. In addition, the fully wireless air conduction earphones are equipped with directional sound transmission technology, which makes sound transmission more concentrated and can effectively reduce sound leakage. 【46 Hours Continuous Playback & 24 Months Manufacturer Warranty】The Bluetooth earphones alone can play music continuously for up to 19 hours on a single charge, and up to 46 hours when used with the charging case. They also support fast charging, with just 5 minutes of charging providing 1 hour of use. 安心保証 (Peace of Mind Guarantee) *Products purchased from OneAudio Direct come with a 24-month peace of mind guarantee.
