I wish I could show you what was behind this door:
But unfortunately I didn't have my camera with me when I was allowed to enter (together with the AKG guy I am in contact with). So You'll have to stick with my description: A limited edition series of the AKG K518 DJ in all colors of the rainbow! Red, yellow, blue, purple...they looked amazing.
I do not know if they will hit the US market. However, I will definitely get one in red!
I just wanted to let you know that they are listed on the AKG website.
