I am looking for an sound cards to plug it into an IPod, as I am using iPod from long time but i donât find it good, to always use headphones so I need some kind of sound cards to listen songs without headphones, as I have been told by my friend that regular use of headphones can cause hearing problems. Also when i use my headphones it sometimes gets very tiring and irritating so i need an sound cards (audio extender) which serves me best!
