• IPX7 Waterproof: Nano-coating protects against sweat, rain, and splashes, making them suitable for workouts and commutes.
• Lightweight Construction: Designed for all-day wear without pressure or discomfort.

Connectivity & Controls

• Bluetooth 5.4: Provides a stable connection with 98% connection stability and supports multi-device pairing.
• Multifunctional Touch Screen: The full-color display on the charging case allows control of music, calls, noise-canceling modes, and settings without using your phone.
  • Functions include: music playback control, track switching, call management, noise-canceling mode selection, 7-language switching, wallpaper customization, screen brightness adjustment, headphone search, and timer.
• Touch Controls on Earbuds: The earbuds themselves have touch-sensitive controls for basic functions.
