At $130 for high def hp"s, these are amazing! I've was using another brand (More expensive) and picked these up when the others broke. These sound far better and are indestructible. They are built on a modular platform which enables the user to swap out colors in the cables and Headbands with the removable speaker system. Stoked on the Tracks HD and the price for the full sound- can't wait for the over-ears to come out.
