Input:
I have owned these headphones for about 3 months now and was surprised at how great they sounded. Whenever i used them, they went right back into the case in a tangle free fashion. i wound them up in my hand, which is what i suspect was the cause of them breaking. One day the left earphone went out. I had thought it was temporary, but upon further inspection, they were shot. I figured that every time i wrapped them up, i would pull the wire more and more out of the actual ear-piece, and cause the wire to become disconnected from the speaker. I was extremely frustrated because i do not think i have taken better care of another pair of headphones before. I guess all i can say is try not to make the same mistake i did and take better care of them.
