Pebble Core

Designed to free you from the need to drag your phone with you every time you run, the Pebble Core is an iPod shuffle for modern times. It uses its own 3G connection to stream music from Spotify, and connects with your headphones wirelessly over Bluetooth. Since your phone also doubles as a location device, the Core packs GPS into its squarish black body, syncing the data with a number of popular fitness apps once you're back on WiFi. And while you hopefully never need it, there's also an SOS function built-in so should an emergency happen, you can still call for help without actually needing a phone.
