Want to show your love and loyalty to a brand in the most obnoxious way possible? Why not grab a baseball cap that will draw attention to it not with its logo but with the music that it’s blasting. Yes, music. If you have forgotten already, and we won’t blame you if you did, Atari announced its Speakerhat idea a few months back. That idea has, for better or for worse, turned into a product that you can now buy, wear, and, of course, belt out tunes for everyone to hear.
