Details are rather scant on this little gem right now, but here's what we can tell you: you're looking at the world's first HD Radio portable device prototype, and it's slated to do just about exactly what you expect. In other words, it'll slip into your pocket, tune into HD Radio as well as standard analog FM broadcasts and connect with any set of cans that use a 3.5 millimeter headphone jack. Unfortunately, the manufacturer is being kept under wraps, and there's no Bluetooth headset support baked in. That said, you can expect it to land in an undisclosed "big box retailer" this summer for under $50.
