You can't go wrong with the price. They definitely look like high-end IEMs, but I feel like the bass is a bit lacking, although most people will find them adequate. One problem is the packaging. I use them on the back because they fit and look better. I also replaced the ear tips with foam as the supplied rubber tips weren't as comfortable and didn't offer the best noise isolation. Overall I'm satisfied, although not as good as my previous IEMs, the Allen & Heath XD-20s, which I paid under $25 for. Great headphones, lasted me a few years. I've only been using these KZs for a few days so we'll have to see if they improve as they break more.
