While the popularity in noise-cancelling headphones continues to rise, these sleek earphones go against the grain.
The 'Focus' headphones where designed by Kwanjun Ryu and were created because the designer believes that noise-cancelling devices can be dangerous. In heavily populated or dangerous areas, not being able to hear what is going on around you could certainly have an impact on safety. These sleek earphones were designed to enable external sounds through a simple switch when needed, all while the user's audio plays. The user can switch it back whenever they wish for the noise-cancelling feature of the headphones to be turned on.
In order to ensure safety in populated areas with traffic, headphones that allow the option for both noise-cancellation and to hear surroundings can be crucial.
