I went through many many earphones for years with many not lasting a month. I never abused them but I'm a heavy user. Usually the cable controls were the first to break, then a driver would usually break. I never had a problem with my UE900 though. I found the build quality to be quite nice. They look good and sound good. The swivel on the cable I didn't like though...it made them kinda confusing to put on.
Like, UE900 is a great headphone sonically and aestethically, but I had a pair of cheap Shures that went through hell and back with no problems and this thing split into two when I tried to remove the cable once.
