Hey, looking for some portable earphones to compliment my FA-003. The 003 is just way to bulky to travel with (I have... twice) and I'm looking for something relatively cheap. Are the KSC-75 good for classical? They seem like must haves I was also looking at the RE0, RE-ZERO, Image S4 and MS1i (headphones). Etymotics aren't available where I live. Thoughts?
