I heard the new matte solo hd's changed their sound as well. It's kinda funny when you think about people saying the matte ones sound better than the glossy ones.I'm not talking about the original solo without the hd in their name.
I have tried audophile headphones (m80, m100, cal, momentum, ath m50) and I still prefer my original studios. None of those have even remotely close bass quantity except for the m100 but it doesn't look that good. I legit prefer my studios and if they broke I would buy them (the 2013 version now obv) over the others. Everyone always says the bass overshadows everything but I can hear everything perfectly fine. I'm beginning to think no audiophile listens to rap/dubstep.
