Wireless Bluetooth Earphone Connection Tutorial (General Steps)
1. First pairing connection (using a mobile phone as an example)
Enable headphone pairing mode
Open the charging room → Long press the power button for 3-5 seconds until the indicator light alternately flashes white/red blue.

How to wear headphones
1. Distinguish between left and right earphones
Headphones are usually labeled with L (left) and R (right). Before wearing, please confirm the direction and avoid wearing backwards, as this may affect the fit.
2. Adjust the ear clip area
Clip design: The earphones are fixed on the auricle with elastic clip arms, and the following steps are required when wearing:
Pinch the arm with your thumb and index finger and gently stretch the elastic part.
Align the headphone unit with the ear canal and wrap the arm around the back of the auricle (similar to the position of the eyeglass legs).
Slowly release the clamp arm and let it naturally grip the ear, avoiding excessive force and preventing pressure.
