“The Realistic 33-1070C is a "white label" microphone made by Shure exclusively for Radio Shack, and for all practical intents and purposes, it's an Electro-Voice RE50 clone. Essentially inside it's a Shure VP64A housed in a mic shell shaped to look like an RE50, but a bit shorter. There were several revisions with different impedance: 33-1070B with 500 ohms, 33-1070C with 300 ohms, and 33-1070D with 200 ohms.
