The AudioWizard shower music system from Mr. Steam introduces immersive sound quality to the shower. With the touch of a button, wireless AudioWizard connects to nearly any smart phone or other audio device via Bluetooth, retaining up to eight devices in memory. Set it once, and then whenever one of the eight devices is in range, it will automatically sync with the AudioWizard. The unit allows the user to select tracks and control volume safely from inside the shower. It is customizable for up to four speakers.
