Hell yes! they are bright like hell! Have you not heard the DJs who play MP3s from a laptop? If you don't hear brightness or a thin sound you must be deaf.  Be happy with your iTunes buddy!

They are probably deaf from too many loud nights and boost the highs to compensate for their damaged hearing. I've worked with plenty of DJs that do this.
