That coloring is what makes the Beats so magical for me. That and they look so pimp.
Okay, the mids on these aren't really muffled. They're colored loudly in an incredibly weird unnatural way. So much so that pretty much every frequency smears with the adjacent one. It's not really "good" for the price, but seriously. I like these more than the M50's everyone seems to be so devoted to. The Pros are actually fun to listen to (outside of the BB thing.) and not meant to sound accurate. But they kinda realized that and ran as far away as natural as possible and made something that makes AT's mids sound neutral.
