Tips for Hearing Conservation
1. It is recommended to turn down the volume of the device before
using the earphones, and gradually increase until it is suitable
when you start to listen.
2. In order to protect hearing, please do not turn up the volume too
high (doctors pointed out that listening at high volume for a long
time will damage the listener's hearing).
3. When tinnitus occurs, please lower the volume or stop using it.
