Join Dallas and the McElroy brothers (hosts of My Brother, My Brother and Me) as they compete to see which brother has the best ear. We dust off our old mystery sounds to test the McElroy's on their knowledge of pop culture, science, and the mundane. Which brother has the best ear? Find out, in this heated and hilarious game... of mystery sounds.

Twenty Thousand Hertz is produced out of the studios of Defacto Sound and hosted by Dallas Taylor.
