This multi-functional wireless Bluetooth earbud set is a practical audio device suitable for travel, sports and office use. The charging case is fitted with a high-definition LED touch color screen on the front, which displays real-time power of both earbuds, total remaining playback time and current clock. Multiple planet-themed wallpapers are pre-installed. You can switch tracks, adjust volume and change call modes directly on the screen without taking out your phone, and the visual interactive design greatly simplifies daily operations. It delivers impressive battery performance, offering up to 30 hours of total playback time together with the charging case. The low-power Bluetooth chip reduces energy loss, so you won't need frequent recharging for daily commutes or long trips. Built with premium dynamic drivers, the earbuds reproduce delicate vocals and rich deep bass. Combined with call noise reduction technology, they block ambient background noise to bring crisp stereo sound for music, videos and online calls.
