manaox2 summed it up perfectly. I find that a majority of the people who OWN both earphones, tend to lean toward the Triple.fi 10 Pro. It, in my opinion aswell is a better sounding earphone..BUT..If you can wait...I would go for the Westone 3.. I hear its awesome and that it surpasses both TF10 and SE530/E500. But between the 2 mentioned above, go the TF10 in my opinion. Oh and the reason I say OWN, is because I find that with my earphones, I need to own them, to really fully experience them. I have heard the e500, but I live with triple.fi everyday and thus I know its true potential. I like the sound better than the e500, but again, I have only heard the e500, I can't say that I have had a chance to sit down and experience/live with it. From what I have heard, Id say the triple.fi is much better, but take the advice from someone who lives with the 2 earphones and can tell you more about them.
