I bought these to replace my last pair of skullcandy's and I love them! I was a little skeptical at first because I wanted something for working out, running, biking, etc. They stay in really well and block out noise much better than my last buds. The sound quality is also much better and almost as good as my old bose buds. The only thing I miss on these is the cord volume adjustment, but other than that they are perfect.
