This is a limited edition Sennheiser HD 800, in glossy black with Sennheiser-blue accents. The custom coloring was applied by Colorware, but this specific color scheme (the Sennheiser-blue in particular) was only available for a very limited run. Also in the photo: Ray Samuels Audio Raptor OTL tube headphone amp; HRT iStreamer iDevice DAC; Apple iPhone 4S. (Cabling by Cardas and AudioQuest.)
