From my experience, Klipsch has the BEST sound out of them ALL! Bose or Beats by Dr.StupidDre don't even come close!
If money isn't an issue, and you are a true audiophile, go with the Klipsch x10i, you will love them!! They are the most comfortable in-ear headphones I have ever used! They are so light, you forget that they are in your ear.
Pros: -Has unbelievably good frequency that also keeps up to the widest range of speaking and bass you can find.
-100% noise cancellation. I also use them when I need to study...works real well.
-Noise reproduction is ultra smooth and balanced.
-Awesome bass at all levels, as well as voice/speaking.
Cons:A little expensive, but you definitely get what you pay for.

That's what I had before upgrading. It was actually hard giving it away to my sister because I liked it so much! Good thing it was for a good cause
I've had bose before, and I believe all you are buying into is the name! Vmoda/Senhheiser have products that are better, while still being cheaper! The only cool thing about bose is that everyone kind of knows the Bose name, so they automatically think it's cool! You need a real audiophile to know Klipsch, B&O, and B&W, to which comparing them to a bose unit is like comparing a Mercedes S65 to a kia rio!
Here's a tip, one that you might have already known: Don't take advice from a newbie in-ear headphone user. To them, a 2 dollar i-e set from ebay sounds good when you surround the small speaker with a soft rubber to channel the sound into your ear! It takes many purchases to know what is good/bad. So when you read reviews on apple's site, or another site, discard reviews from people saying something like this, "WOW! This was my first i-e set and it sounds AMAZING!!"
I'm warning you though, once you go Klipsch, you won't ever go back!
