I can say that I like these more than the Custom 3. The Custom 3's came off kind of sterile or lifeless to me. I couldn't find the fun in them. These are definitely more fun. Technically better?? Probably not. I guess it depends on what you're looking for. If you're looking for this "Slight bass emphasis with a neutral midrange and slightly laid-back, but very well existent treble." That's what I hear from the 215's.
