They are all closed around ear phones so any of them work, i just want to know what sounds the nicest. I'm looking for a nice surround sound like sound, since my PX100's sound like they are coming from inside my head. I listen to rock music. what do you guys think? The sony's look the best to me.

Right now I have Sennheiser PX100's and Sennheiser HD202's and they are nice but I want some real audiophile headphones now... My choices are between: Sony MDR7506 (I've heard they are they best sounding headphones under $200) Amazon.com: Sony MDR7506 Professional Large Diaphragm...

Meizu M6 has SRS WOW and is the best sounding portable player you can buy.
