Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------ High-quality sound that brings out performance Semi-open wireless earphones that reduce hearing your own breathing and footsteps Performance tracking sensor that can measure heart rate and body temperature Tough, powerful and comfortable to wear with IP55 rating Connect to various exercise apps
