LISTENING TO LOUD MUSIC ? - NO !
Listening to music via headphones tempts
into listening to louder music than loud-
speakers would. A high volume that affects
your ears for a longer period can cause lasting
hearing defects. Protect your sound hearing;
Sennheiser headphones are good even for low
volume musical enjoyment....
