We have covered some very cool earphones and earplugs here in the past. Shush happens to be another smart earplug that lets you adjust the sound volume easily. You can rotate it clockwise to reduce the volume or counter-clock-wise to increase it. Regular earplugs eliminate sounds entirely, so they are not practical in every situation. Shush gives you more control. Just rotate it to gradually reduce the background noise.
Shush will be available in two colors (more colors will be chosen). It simply eliminates the need to remove your earplugs every time you need to answer someone or hear something. Like other earplugs, Shush can help you become more productive. You can support this cool project on Indiegogo.
