An entertainment system for use with a magnetic resonance imaging (MRI) device that includes video glasses and headphones. A Faraday shield encloses the entertainment system to reduce adequately RF signals from entering or leaving the entertainment system. The entertainment system may have non-ferromagnetic RF low-pass filters between parts of the system, such as the control unit and the video glasses, to reduce higher RF signals from entering or leaving those parts. To replace the battery and or entertainment media, a person opens the entertainment system's Faraday shield when not MRI imaging or outside the MRI magnet room. The door has an Faraday shield overlapping the system Faraday shield and making low resistance RF contact. The entertainment system has a minimal amount of ferromagnetic material so that it may operate within the high magnetic field of the MRI magnet bore with minimal performance degradation. The entertainment system uses non-ferromagnetic speakers in the headphone. Passive ear protection and noise cancellation reduce the loud noise of the MRI system heard by the patient to a level where the patient can hear the entertainment. The entertainment system includes a charger for the rechargeable batteries.
