Hi guys, I am new here! I used to be an IEM guy, I own a pair of sennheiser IE6, but it broke . Recently, I am getting interested in over ear headphones. I read up about closed vs open but still can't really decide which is better and to be honest, still quite confused on the technical aspects. I am looking at something around $100~150. I listen to all kinds of music, literally all kinds but I do like music w/ heavy bass so being able to hear the bass is quite important. I am thinking about KRK KNS6400, ATH M50S and Grado Prestige Series SR80i or 125i. I would really appreciate it if someone can shed light on which is better or if you guys have better suggestions! Thanks a lot!!
