Using your Behringer True Buds is easy. First, charge the earphones and the charging case using the included USB cable. Once charged, take the earphones out of the case and they'll automatically pair via Bluetooth. Choose the right size of silicone earplugs for a snug fit and better sound isolation. You can control your phone, adjust volume, and play or pause music by simply touching the earphones. When making a call, the built - in CVC 8.0 will help keep your voice clear. For battery life, you've got up to 4 hours of continuous use, and the charging case can give you an extra 12 hours. Remember, these earphones are splash - proof (IPX4), but don't submerge them in water. To keep them in good condition, clean the earplugs regularly and store the earphones in the case when not in use.
