Mine don't dissapear. While I am trying to work the 8a's keep calling attention to themselves with all of this detail and and bass and things I have never heard before that I close my eyes and get nothing done. I have to go back the the TF-10 reshells to be productive without distraction and then I just sit there and wish I was wearing the 8a's. Tough dilemma to be in, no?
They physically disappear - taking my productivity with them.
Without a doubt. Mine were $1200 and I seriously consider that my best head-fi purchase. Worth every penny.
