XII. Hearing protection
Suggestion for preventing the hearing damage:
1.When using the headset, too high volume may cause the hearing loss.
2.Please adjust the volume as appropriate: adjust the volume to the lowest level, open the player, increase the volume gradually until you feel comfortable in hearing and definition is not distorted.
3.If the dialog and other similar ambient noise can be heard without interference, the volume is appropriate.
4.Adjust the volume to comfortable level and keep it. In case of the tinnitus, discomfort or sound distortion, please decrease the volume or stop the listening, and check your acoustic state.
