3. Getting Started

Note: Before first use, place headphones in the charging case and charge for 2 hours for optimal battery capacity and life. Use only the original USB-C cable. Headphones will turn off when charging. If unused for a long time, charge the battery at least once every three months to prevent loss of charge.
