I listen to a lot of music and wish to have a quality headphone for working out whether it be running on the treadmill or lifting weights. My workout list goes from house,rap,metal. I was thinking of Sennheiser PX-100, Grado SR80i, V-MODA crossfade, Koss KSC75 (might as well buy as they are cheap). I am just concerned about that the ear foam might get sweaty from the gym. Can you wash the ear foam? Sorry I don't really own many headphones but HD555 and Ultimate Ears 700 which seems to be broken as the headphones become detachable. Side note I might have weird/big ear canals or ever foam piece does not work with my Ultimate Ears 700 anymore and I bought the variety pack from ComfyFoam and the ear foams have been torn but small seems to work. Guess bad luck. Thanks for any help I'm new lol.
