Any advice? I currently have Sennheiser PC350 but though the audio quality has been great, they've been slowly falling apart. First the cover of the earphones malted over my face, then the inner padding disintegrated and the wires have long since been fraying, only today did it finally give in and the mic has stopped working. So! I need a new one, anyone got some good audio quality headphones that can take a lot of abuse?
