The buttons on the HUAWEI FreeLace Lite earphones turn yellow

The earphone buttons are made of TPU soft rubber and may turn yellow over time if exposed to things such as sunlight, sweat, and dirt during daily use.

During daily use, avoid exposing the earphones to direct sunlight and avoid contact with colored oily substances (such as cooking oil or cosmetics). If the earphones do come into contact with greasy substances, gently wipe them down using a clean, lint-free cloth dipped in water.
