    Bluetooth Device Precautions:

16. Battery-powered devices are shipped with a small amount of charge for safety reasons. Before using them for the first time, please ensure that they are fully charged.

17. Bluetooth earphones, as wireless transmission devices, undergo reception and conversion processes, which can cause certain delays. This delay is considered normal for Bluetooth earphones.
    Wearing Precautions, Part 1:
    The ear clip is made of a high-polymer memory material that is adjustable based on the shape of your ear.
    If the ear clip feels too tight when wearing, gently bend it a few times within a range of about 60 degrees to reduce the clamping force. With prolonged use, the ear clip will mold itself to the size and shape of your ear based on your usage.

Note: Do not bend the ear clip at an angle exceeding 90 degrees, as it can cause stress damage to the material, making it difficult to restore its original shape. Wearing Precautions, Part 2:

Adjust the speaker to align with the outer part of your ear canal for the best fit.
Pay attention to the orientation of the earphones when wearing them. The side with the speaker opening should be placed inside your ear, while the side with the letter “L” or “R” and the charging metal should be placed behind your ear. Otherwise, the sound may be too low.

Note: For those who are new to this type of earphones, there may be an adjustment period when first wearing them. After a few uses, you will become accustomed to them.
