I started with the m2's (well, techincally the proalphas). enjoyed them so much I bought as gifts for friends who were into beats iems and "converted" them. these BE's will make the m2's sound like straight up S**T (pardon my french). not exaggerating either. As good as they m2's were, you'll realize the m2's belong in the cheapo category for a reason. and please. YOU CAN'T HAVE 'EM!!!
