Pros: everything ..
Cons: dont cut all sound from out side ..
i dont want to say too much cuz its nearly discontinued , and its hard to find one , it was even then , the comfort is awesome ,the sound stage is the biggest i have ever heard even bigger then my cx500 . i own two of these , so you can think how much i love them .. good bass , nice mids , good highs and the best thing is its really fun to hear these ..
onw thing i would like to say that if you hear these for a week and go back to , pl50 or say cx31 , you will through them away and come back to this , these are so fun cuz of the bass and the sound stage ..
if you can find one , go grab one , cuz you will miss the fun ..
