Typically, we have problems with any FM transmitter that's designed for a single family of devices (see the dock-connector iPod-only Monster iCarPlay). DLO's TransPod for the iPod Shuffle seems one-dimensional as well, with its Shuffle-friendly USB-port design. But you'll find an audio line input and even a line output for cassette adapters and the like on the bottom of the device. Signal strength, even in San Francisco, was not a huge issue. At the 88.1 frequency, we usually had a static-free experience. Sound, though, ranks on the lower side, with lackluster bass and typically AM-like quality, but that's par for the course for most FM transmitters. Still, we love the fact that unit charges the Shuffle--which has a tendency to die when you most need it--and any other device that draws power over USB.
