Headphone cables can be difficult things. They tangle, kink and can even break. But what are you gonna do? Maybe the answer was to give the problem to people who really know headphones: high school students.
A group of students working as part of a hackathon at the University of Pennsylvania came up with a new twist on Bluetooth connectivity that completely eliminates the need for headphone cables.
If your headphones have a detachable cord, the Spiro XI plugs into the input and hangs on your headphones like a big earring. That’s your Bluetooth receiver. After about five hours, a red LED tells you it’s time to recharge.
