Hey guys. I am looking to buy semi-open, full size, over the ear headphones that are under $100, at most $150. I am looking for like a AKG style self adjusting headband. I am just looking for opinions or suggestions on whats gonna give me the best all around sound. These headphones will be used in a combination of on the go and at home. I will also add that I listen to broad array of genres. Everything ranging from rock and roll, punk, garage rock, metal, electronic music, jazz, rap/hip hop, and etc. Also I want to add that I will most likely buy a portable headphone amp later on, something like the FiiO E6 Fujiyama. If guys have any suggestions on cheap portable amps that would be great too or certain combinations of headphone and amp that you would recommend. So far the list I have come up with is as follows:

-Also I would like to add that I would like to go with AKG but I have heard that their build quality as plummeted because the headphones are being manufactured in China now. Whats your guys' opinion? Any help would be greatly appreciated because I know nothing.
