Sowar to use the earbuds affect my ear?

I use it 5 hours a day I have an iPhone but the voice of any song is in the middle

15 minutes is too long and it damages your hearing; hearing loss is very serious---loud and long use of buds kill off tiny hair-like which help us hear and once killed off they don't regenerate. 5 hours will lead you to suffer hearing loss way too young and by the time you get old, you won't hear a thing; hearing aid will be needed.

take care and stop using too long
