Looking for something that looks like the past but sounds like the future? Look no further than the teenage engineering OB-4 magic radio. This portable high fidelity loudspeaker pairs two four-inch bass drivers with two neodymium tweeters. Together, these ensure that you get a natural, clear sound that boasts 38 watts per channel—equal to about 100 decibels. Moreover, this magic radio lets you use a variety of sources: line input, Bluetooth, FM radio, and disk. Designed with a simple look and interface, it provides you with all you need and nothing extra on the exterior. Recording what you listen to on a rolling two-hour basis, the OB-4 lets you rewind and replay with ease. And you’ll love the smart spiral antenna that helps it work even in touchy spots. Finally, you’ll get up to 72 hours of battery life on a single charge—so you never have to stop listening.
