A question for people who listen to music everyday...

[noidea]

^ actually, almost all earphones from a certain price on have noise cancelation(which you should never use when in a city(you wont hear cars!) or when driving bike or something(just a note xD) and that sony protection...surely doesnt work, the only way to protect your ears is by going down in volume and bass, that "protection" probably is a volume limiter only
