I looked at this for a long long time.
This is a basshead design not audiophiles. It has tuned ports built on a 55mm driver. It's rated to go down to 4Hz.....4....long past the audible. I have never heard Hip-Hop on headphones like this in my life. I got so excited at the shop I had to calm down...came here and saw the hype turned derail thread and never read anything to make me think I was hearing things. It was rumbling off my skull. Nobody was talking about hip-hop or eq induced slams. This is like the coolest headphone I have ever heard by a long shot. Right out the box it's playing beautifully and is maybe the most eq friendly design I have heard.It does whatever I eq it to do. As it sits now the 77's are a shade harder hitting but they were tuned for weeks over and over until the slope matched the setup. This is about even right out of the box. The 55mm carbon Kelton Subwoofer is pretty much assuring me that with minor tweaks and just for kicks it will no doubt slam harder. It may be hard to distort if even possible??
The outside design is for at home the short cord is portable friendly only and it's got a dedicated subwoofer....hmmmmm...who would want that??....um.....a basshead.
