I wrote to the technical support rep of AKG Acoustics to ask a question about the durability of their new K181 PRO DJ Headphone. Soon I had a nice answer. To be fair to other brands, I will also send them an e-mail asking the same question. In the near future I'll post their answers on another topic ofcourse.
The companies I will write are Pioneer, Technics, Sony, Vestax, American DJ, Stanton, Numark, Behringer, Denon and Sennheiser. If someone knows any other brand of PRO DJ Headphones I forgot please let me know soon.
News for GJ's. In my search for headphone manufacturers I stumbled on the new Sci-Fi looking turntable of Vestax. Vestaxpro.com
