I'm on the search for some in-ear headphones, mostly for rock music (Metallica / ACDC). Here are my criteria:
1. Best price on Amazon/eBay < $100
2a. I don't think I need them to be ultra balanced / accurate. So, a colored EQ is fine.
2b. Because I listen to rock, I would prefer the bassline to be punch-y and the guitar solos to scream at me. (I was underwhelmed by the Klipsch S4)
3. I would love an in-line remote/mic for my iPhone, but if the sound quality is what I want then I'd consider non-smart earphones.
