Built-in lithium-ion polymer battery, the headset can be used continuously for about 4 hours when fully charged, and the total use time with the charging box can reach 18 hours.
Through the IPX4 waterproof standard, the multi-process strict design can effectively prevent sweat, and give the headphones better safety protection.
