I am looking to upgrade my iPhone/iPod headphones and have zeroed in on these two models--mainly b/c they are at my maximum pricepoint (and I am not a huge fan of Bose products). Can anyone with experience in these--especially if you have experience with both--give me some feedback? I mostly listen to Alt Metal (Tool, Chevelle, etc) but also listen to classical and less bass-heavy stuff. Also, if anyone has run with either of these, I'd be interested in how that went. Thanks!
