Blocks is an assortment that uses two or more contrasting colours for each model, creating a colour block effect that highlights each unique shade. With their robust and streamlined triangular design, Coloud Headphones are built to withstand the pressures of everyday listening. Minimal parts and mechanical construction make these headphones super durable, reinforcing them against the pressures of everyday listening. Each pair of Coloud Headphones is ergonomically designed for ultimate comfort and wearability. Using a concept we like to call 3D ergonomics, each model is crafted to follow the angles of the human head for a comfortable fit. Because most music players today are also mobile phones, we"ve built a microphone and remote onto the flat cable made from TPE on all Coloud Headphones - a feature that"s handy in the real world. This means you can pick up and answer calls with your headphones, as well as forward and rewind your music using the 3 Click Microphone. The patent-pending Zound Lasso, together with the flat cable, is the solution for a tangle-free life. The pliable plug bends 180 degrees to hold your cable in place when you aren"t using your headphones, and its angled design protects against breakage at the connection point. Just wrap the flat cable around the Zound Lasso and secure it with the pliable angled plug.
