I'm offended, I'm 15 too you know!
Anyway. Positive reactions from my buddies. One swore by beats, so I made him buy a PortaPro and Antec dBs. Now he comes to ask what senns he should buy. Looking to get him to buy the Alessandro MS1. I gave another guy my Monoprice 9927, which he uses a lot. When letting him audition my Sony MDR-ZX100, he declined saying "don't tempt me, I'm saving for an SSD. A musician friend heard the ZX100s and bought one of his own. Don't need high end gear to convert people. Also, 2 other people heard the Klipsch Reference S4i, and the PortaPro, to great approval.
A friend tried out many headphones at a Headfi meet a few days ago.
...Then he tells me he thinks his $30 Razer Morays are head and shoulders above all the headphones there.
Another friend enjoys the Alpha Dog and the LCDs a lot.
