both at this point are equally priced. i've been looking at both and they both seem to be good quality headphones, does anyone have a review on the bass of the sennheiser? is it a good amount? the 595's i know are more audiophile, and the open-air design scares me a bit because i don't want to hear everything thats going on around me while i listen to my music. so...suggestions, reviews...GO!
