The Spark Digital Lightning condenser microphone contains its own DAC which means that all the signal processing is done before the audio is sent to the device which you are recording to or broadcasting from.  That saves processor cycles on a PC but also means you can use this with a phone and other mobile devices and still produce audio of a decent quality.  It comes with a shock mount and your choice of either USB and Lightning cords or USB and the old style 30-pin Apple connector.  You can control volume, gain and mute directly on the mic as well as switch on a Focus option which alters the bias voltage of the condenser capsule similar to a low frequency filter.  Check out Benchmark Reviews full look at this ~$200 microphone that can almost compete with studio mics bearing a much higher price tag.

"The Spark Digital from Blue Microphones is an all-in-one solution for high quality digital audio production. All the signal processing is done inside the body of the microphone, and the interface to your computer is through one of several available serial connections. The Spark Digital supports USB 1.1/2.0, the relatively new Lightning connection, or the older Apple 30-pin interface, through the use of separate cables for each connection type."
