These headphones are really expensive, but they do give great sound. I gave them 4 instead of 5 stars because honestly I don't know that they're worht the money over a pair that's 2/3 of the price. However, I really like them. They are comfortable and stay in my ears when I'm running, which is something that's hard to find. They also filter out most of the outside noise, so that I can hear without having the volume turned too high. That's a plus for me. Also, the buds themselves can be removed so that if the wires get worn out, you can just replace the wire - which is much cheaper and less wasteful. I think I would buy them again because I know what I'm getting, and that comes with peace of mind.
