Query: Godd bass, bad quality, bad fit., no customer support

The earphones has nice bass which is perfect for listening to hip hop music. The fit of the earphones is bad since it will constantly fall off during physical activity. I bought the ear plugs 1 months ago and it has stopped working because the wires of the ear plugs connecting the the mp3 player was broken, a sing of bad quality. To make things worse, customer suppport was unavailable-i called the koss customer support and received a recorded message stating that "its offices are relocating and uable to take any calls". What a waste of money for a bad earplug.
