The Heil PR 40 dynamic microphone manufactured by Heil Sound, Ltd. is the winner of radio’s most prestigious technology honor, the "Cool Stuff" Award, given by the editorial staff of Radio World newspaper at the NAB2005 convention in Las Vegas.

Radio World U.S. Editor in Chief Paul J. McLane said the "Cool Stuff" Award means a product was selected by a panel of engineers and industry journalists as notable for its design, features, cost efficiency and performance in serving radio users. It means the product caused them to stop in the aisles and say, "Oh, cool!"

The winning companies may use the "Cool Stuff" logo in their marketing. Winners receive a placard for their booth, and later the award itself.
