Wireless headphones and headsets are the bomb. You can groove at your desk or play video games really loud into your lugholes. What differentiates them to the Earin (it's a singular at the moment), is that they have cables that run between the two buds. Earins, do not.

Instead of a cable, the Earin works by charges in your pocket whilst they are not in use; put them back into the handy carry tube and they will pull charge from the internal battery within the tube. The design and function of said headphones is the brain dump of former Nokia and Sony Ericsson employees so there is a decent amount of experience behind the project.

To get a pair, all it takes is a $99 contribution on the Kickstarter page with the delivery date being January next year.
