These are bad to the bone...I listen to all types of jams and even bump the rap trizacks. I have subs in my car and would not rock out on shit headphones. The Asym's are the first bud that stays in my ear while working, running, shredding and tuning out college professors. I actually sent them through the wash on accident and they still rock hard. NO, i do not work for dogfunk (even though I would like to) these are forreal legit.
