Skullcandy earphones are great for music with heavy bass and is excellent with sound quality but they never last more than a month. I previously owned three variations of Skullcandy and they all die out within a month. :/
My S3 heats up a lot when I have many stuff on at the same time to the point it burns to hold the phone. Recently, I think there was a news about a guy's phone catching on fire on top of the S4 while charging.
