Hey, I ended up going with the Sennheiser 555s (which I'll order on my b-day next month) instead of the 595s to save $69. With that money building up, i'm planning to purchase IEMs for my mp3 player on the road trips. I listen to rock/hip-hop/metal, and I really want amazing IEMs for ~$100. Can you sugg. any? I was thinking the ER-6i, but people said they lack bass, but make it up in detail. The Shure e2cs are said to have bass, yet lack detail. Thanks in advance.
