If your car doesn’t have Bluetooth or AUX (or if your new iPhone doesn’t have a headphone jack), you aren’t damned to an eternity of listening Serial through your phone’s speaker. This FM transmitter connects to your phone over Bluetooth, meaning you can get audio from any phone onto any car’s stereo system without any wires at all. We’ve seen deals on a lot of these in the past, but never for $10.
