Myvu Corporation’s myvu personal media viewer, crystal 701 allows viewers to experience their videos up close and personal from various portable media players, DVD players, mobile phones and game consoles.  The elegant eyewear brings traditional head-mounted displays out of the world of the techno-geek and into the world of the techno-chic.  Crystal provides VGA resolution and a significant increase in virtual screen size over current myvu models for true DVD-quality viewing experience. Complete with noise-reducing in-ear earbuds by Ultimate Ears for stereo sound and a rechargeable battery for up to 4 hours of viewing time, crystal provides a relaxing way for users to watch their favorite videos on-the-go. 

Macworld’s buying advice:

For $300 you’re going to be paying $100 more for the Crystal than for Myvu’s least-expensive video headset for the iPod, but you’re going to get better-quality video and a sleeker design. While it’s not perfect, Myvu’s Crystal provides you with quality, private video viewing on your iPod and iPhone--and these days, that’s about all you can ask for in the belly of coach class on most airlines.
