The conceptual 'Gem' wireless earphones are a privacy focused audio solution for listeners who want to avoid unwanted interactions when they aren't feeling talkative. The headphones feature an outer shell that borrows technology from electrochromic smart windows to change from translucent to opaque when voltage is passed through them. This will help communicate to those around the user that they are listening to music and not up for communicating to let them enjoy audio content in peace.
The conceptual 'Gem' wireless earphones are the design work of Robbie Lillquist and will automatically change in appearance when audio is being played. The headphones can also be manually adjusted to let wearers put them in do not disturb mode whenever they don't feel up to talking with colleagues or other commuters.
