The Speakerhat is a baseball cap with high quality speakers and a microphone which use Bluetooth to connect to devices. Atari promises "a fundamentally new social audio experience" with Multiplayer Mode, which allows multiple users to listen to a single audio stream via Bluetooth. The company is also introducing a limited edition Blade Runner 2049 Speakerhat this fall.
