Query: Poor tone quality across the board

The sony NC22 in-ear headphones do not live up to the hype. I put them on and turned on my ipod and was ready to return them immediately. The treble sounds tinny and the bass is practically nonexistant. The vocals and drums are clear because there is no other tone to get in their way.To be sure, I also plugged them into my computer and listened to the same songs. There was no difference -- the tone problems were not from the player, but from the speakers.I would definitely recommend getting the non-NC Bose in-ear phones instead of these, and I am going to be trying to Etymotic ER-6i very soon.
