Weightless Wearability

The Knock is ergonomically designed to provide non-stop comfort. It's an ultra lightweight headphone that's strong enough to withstand the pressures of everyday listening. It delivers a sound that is clear and distinct, and comes with the "lasso plug" that holds the flat cable into place, so that your cord won't get tangled during transport.

Coloud takes a no fuss approach to the concept of sound. Available in three models, two color assortments and multiple color ways, all Coloud Headphones feature a mechanical construction and minimal parts, and are ergonomically designed for non-stop comfort. Each pair of Coloud Headphones also comes equipped with a microphone and remote on the cord for picking up calls, and features the Tangle-Free System for hassle-free transport and listening. The flat cable can be wrapped around the patent-pending Zound Lasso and secured firmly into place with the pliable angled plug

Coloud Knock Blocks uses two or more contrasting colors for each model, creating a color block effect that highlights each unique shade.


  • Mic & Remote – pick up and answer your calls with your headphones, as well as forward and rewind your music using the 3-Click Microphone.
  • Tangle-free system – 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.
