Thanks for the input. I'll probably get the EP630s from that link (only $10!). I'll also pick up the ER6i and see which one I like better. Either way I'm sure they're both much, much better than the iBuds and I can just stick with the KSC75 when I don't need isolation.

I take the bus every morning and I need some headphones that will provide some isolation. I've had to resort to using iBuds even though they provide little isolation and the sound quality isn't all that great. I have KSC75s and enjoy their sound, but unfortunately they provide no isolation. My...
