great choice with getting the senn's really love mine and they sound fantastic
Sound quality wise I like my Shuree E2C's,
do not go with the e2c's.
maybe i run hotter then other people but i find that when i have the wires i looped them back over my ear (i prefer it that way) the cabling on them dies so quickly (either i melt the goddamn casing or they just fall apart?!)! i went through 3 before i couldnt be bothered with RMA's and switched to senn.
I've had mine years now, no problems or sign of melting.
