S-Logic™ Plus:

S-Logic™ Plus is an enhanced version of the original S-Logic Plus™ System based on the earcup design and acoustic tuning methods pioneered in the exclusive Edition9. S-Logic Plus™ works by using specifically designed earcups, acoustic reinforcing and stereo tuning to manage the sound and get the most out of your headphones. These methods along with additional damping, specially tuned drivers and the Mu Metal bufferboard component all work together to provide a neutral sound impression with detailed instrument placement and distance perception. S-Logic Plus™ can be found in the all new for 2008, HFI-580, HFI-780 and DJ1 models.
