ORGANIC ESTHETICS
GERMAN DESIGN AWARD winners
"The headphones appear sophisticated, snug and comfortable. The use of environmentally friendly wood and nautical leather give a promise of warmth and, in combination with the open side plate, bestow on the headphones with an almost antique feel. A small footprint and eye for technical details merge together to form a modern, luxurious product."
