Even if you keep your phone in your pocket, the Bluetooth earbuds will not lose their connection. After the initial pairing, the earbuds will automatically reconnect to your device as soon as you open the charging case.

【Hi-Fi Audio and Premium Calling Experience】These wireless Bluetooth headphones feature a professional 14.2mm speaker driver unit, incorporating a composite vibration diaphragm design to prevent sound distortion.

The charging case itself recharges in just 1.5 hours via a USB-C cable. Thanks to an intelligent LED digital display, you can easily monitor the battery levels of both the wireless earbuds and the charging case, ensuring you always know exactly when it’s time to recharge.

【Superior Comfort & IP7 Waterproof Rating】 These sports Bluetooth headphones feature an innovative, soft ear-hook design that keeps the wireless earbuds securely in place, even during intense workouts. The sports earbuds come with ear tips in three sizes (S/M/L) to ensure a perfect, comfortable fit—even for smaller ears. IP7 waterproof technology effectively protects the wireless sports headphones from damage caused by sweat and rain, making them the ideal choice for running, jumping, jogging, fitness training, and yoga.
