1. Please try to charge and observe whether the indicator light inside the temple flashes;
2. If it flashes, it means that the two temples have not been bound. You need to disconnect the Bluetooth of the mobile phone, turn off the two temples, and then turn them on at the same time, wait for 3-5 seconds for the temples to adapt, and bind the phone after the adaptation is completed.
** Remember to turn on both temples to connect. If you only turn on one temple, only one temple will make a sound.

Please check whether the gold point of the magnetic charging is in contact, or swap the left and right magnetic charging terminals. Try to keep the charging cable at the top. Try not to touch it frequently during charging. If the indicator light on the inner side of the temple flashes, it means that it is charging.

We usually have 3 types of lenses, one is transparent anti-blue light, one is black polarized, and one is transparent photochromic. If the SKU you order is only transparent anti-blue light, it will not change color when exposed to light. You need to buy our photochromic lens SKU to change color under the sun. Please don't buy the wrong one.
