Storing smartphone earphones in your pocket or bag normally always ends in a birds nest of cable coming back out, which then needs to be frustratingly unraveled. Inspired by the suction cups on an octopus’ tentacles, designer Donghee Suh created this pair of cool ear-buds that are easy to manage. The Octopus ear-buds are fitted with a silicon flap, which retract to become an impromptu suction cup. This ways you can easily wrap the cord around your phone/device and hook on the ear-buds to the screen. Moreover, you can also “gluing” these ear-buds together to get something like a chain and hang around the neck. Pretty cool? Unfortunately the Ear Tentacles are still only a concept at the moment, so don’t expect to see them in stores for the holiday season. [source]
