Update Notes
Add volume limit function
Note:
- When you are setting volume limit, you’d better play music after you finished your setting, cause the default volume limit is 100, your ear may get injured or you may be startled by the 100-level roar.
- A 20-level volume limit is recommended at first (for protecting your listening\）, and then you can change it according to your need later.
