Epson's Moverio BT-100 media viewer suffers from the same geriatric-sunglasses design as every other head-mounted display. What sets it apart, however, is the introduction of the first transparent lenses for see-through viewing. As such, you can enjoy your media in private while still maintaining an awareness of your surroundings.

The BT-100's screen resolution is just qHD (960 x 540 pixels) but it appears to the viewer as a giant 320-inch display positioned about 20 meters away. The mobile viewer is proportioned to fit over your everyday glasses and is accompanied by a small control unit that runs Android 2.2 and features Wi-Fi connectivity, six-hours of battery life, detachable headphones, and 1GB of internal storage augmented by a bundled 4GB SDHC card (with support for 32GB).
