I've been doing a lot of research on both of these earbuds and the reviews for each are pretty fantastic, but I was hoping someone here on the forums could give some insight comparing these two models as I'm going to get either one or the other. Some things to note: Price isn't really a concern, I can get either for around the same price. I own a pair of Klipsch image S4's and I like their sound, but I'm open to something slightly different. I listen to a lot of older music (e.g. Paul Simon) and Choral (e.g. Eric Whitacre). If I listen to new music it's usually acoustic or soft rock. Most often I'm using an iPhone 4 and high bit rate AIFF audio files as a source. I know the x10is have the iPhone controls but that's not essential to me and doesn't influence my decision at all. Any thoughts?
