Last September I took a look at the Vuzix iWear AV920, and I found it to be a decent product overall, though not without its faults. Today I have the new Vuzix iWear AV310 Widescreen for review, and I've found them to be a great choice for someone looking for their own personal cinema or gaming experience. One of the great features of this product is that it can run for up to eleven hours on a single 'AA' battery, that's more than enough for most any viewing needs. It comes complete with connections for iPod and standard A/V as well. The idea behind Vuzix products is privacy, they are small and lightweight allowing you to take them anywhere with you really. So read on to learn more about them..
