I just got the 215K's (live sound). They are a frigging bitch to put in the first few times, but sound great. I also have JVC HA-FTX90's (Japan import). They are also really good. Neither is "V" shaped IMO, rather a shallow "U" shape. I say this as I am using the FIIO E12 to power these. Normal "V" tuned buds don't make my perforated eardrum vibrate like a son of a bitch, both of these do. The JVC's are rated at 150 mW if you are planning on amping them. I couldn't find any input specs on the Shures but, they sound great and show no signs of stress.
If you go with the JVC's plan on a week of burn in .
I listen to classic rock at high volume as I am deaf. The Shures have better sub bass than the JVC's.
