Sony was showing their new personal 3D viewer. This device is marketed as a personal home theater. It is a head set that has two small LCD screens and headphones for sound.
I did not find it to be very comfortable. The sound was also poor no substitute to a good surround system. Unfortunately I could also see the pixels clearly. There were also no picture adjustments for this product if you want to alter the image presented.
I summary this is no substitute for a quality home theater.
