Clever folks over at Ultimate Ears—the company send its UE Boom portable Bluetooth speaker 80,000 feet in the air—that's the Stratosphere to you and me—and brought it back down again. Part extreme test to see if still worked after being exposed to near-space and part promo stunt, the event was filmed and posted to YouTube. And here we are talking about it. UE Boom is a wireless, portable Bluetooth speaker with a 15-hour rechargeable battery. It wrapped in, "a specially developed acoustic skin that is both water and stain resistant." It also offers 360-degree sound. It's 7.1-inches tall and 2.6-inches across. Plus, it survived a trip 80,000 feet up in the air. That's pretty cool.
