Using the Shokz OpenFit Air earbuds is easy. Just take them out of the charging case, and they'll pair with your device automatically. Put the earbuds on with the earhooks adjusted to fit your ears comfortably. You can listen to music, take calls, and enjoy your audio all day. When it comes to charging, put them back in the case when the battery is low. The case can provide multiple charges for the earbuds. For maintenance, keep them clean by wiping gently with a soft cloth. Avoid exposing them to extreme temperatures or submerging them in water, even though they have some water and sweat resistance. Don't use them in very dusty environments for a long time to protect their performance.
