By combining passion and engineering, eliminating unnecessary parts and multiplying the number of useful features, Coloud brings you the Knock, a feather-light and highly durable headphone. Designed using 3D ergonomics, the Coloud Knock is crafted for comfort. With triangular chamfers as a theme throughout, Coloud Knock uses as few materials as possible for easy recycling. Despite being minimal in look, the Knock does not compromise function: the flat cable and patent-pending Zound Lasso are Coloud Knock’s innovative solution for a tangle-free life, with a plug that bends 180° to hold the cable in place.
