A pair of 1.5-inch LCD screens, one for each eye, conveys the illusion of a large-screen TV right in front of you. The displays work together when set at a 4:3 aspect ratio, and when toggled to wide-screen mode, the image is letterboxed over the two screens. So long as you have a video source, you can connect via composite or S-Video inputs for a surprisingly crisp image. Heck, you can even hook this device directly into your PC via a 15-pin VGA monitor cable.
The display--the main reason you'd want these goggles in the first place--works better than expected. The colors will occasionally be off, especially with digital images, such as those in Toy Story 2, but you can easily tweak all the video options via an onscreen menu system. Making adjustments is a simple, straightforward process, but if you fail to save your settings, you'll need to change everything the next time you use the headset.
Unfortunately, the audio playback provided by the FMD-700 is its biggest drawback. A tiny pair of ear-bud headphones are built into the frame, but they are uncomfortable and do a poor job of giving you home-theater audio to properly match the display. The tiny buds just can't handle the bass response, and they produce a headache-inducing hiss at higher volumes. You can tweak the audio settings, but for some movies, such as Terminator 2: Judgment Day, this didn't make a lick of difference. There is an external audio port if you want to use a separate set of headphones, but wearing headphones over the device is not only pretty dang uncomfortable, it makes you look more wired than C-3PO.
In fact, the overall design of the FMD-700 was poorly planned. With two LCDs mounted in spectacles, it feels very front-heavy, like it could fall off your nose. If you wear glasses, you'll find the Eye-Trek very uncomfortable. We had trouble with eyestrain after just 20 to 30 minutes of use. Our gripes don't end there: beyond the unit's poor design, you'll also be burdened by the assortment of cables and the control box that you'll have to haul around. It's a lot of gear, especially when you consider that you have to connect the FMD-700 to another device, such as a portable DVD player or a laptop. (And unlike the Eye-Trek FMD-200, the FMD-700 doesn't include a leather case.) It's just more trouble than it's worth.
Speaking of worth, the final blow is the $1,200 list price. However, since you need a separate video source to hook this headset up to, the actual price is much higher. Adding insult to injury, if you want to use the FMD-700 on the road, you'll also have to buy a battery and a charger, which cost $100 and $120, respectively, bringing the price up to around $1,500. With a high price and poor design, it's hard to recommend this device to anyone, even the most tech-savvy among us.
