Hi all- I'm looking for nice in ear headphones less than $75 (US). These are my requirements: 1. Will be used 25% of the time while running. (So, nice fit is important). 2. Should *not* be boomy. I would like it clear and detailed across the lows/mids/highs. I mostly listen to music that uses a lot of string instruments. Most of my collection in iPod is ripped at a pretty high sampling rate. I considered Klipsch image S4. But folks have concern about the durability. And some feel it has too much bass. Thanks.
