Sony states 100 hours of battery life, but you'll have to buy replacements since these don't recharge.
Sony's 3D glasses have finally hit the market, and they're about what you'd expect from 3D glasses. They're relatively slick looking – or at least as nice looking as the next pair of 3D glasses – and they let you see in 3D.
It boggles the mind that more companies don't make their 3D glasses rechargeable though. In addition to each $150 pair of glasses, you'll have to shell out for batteries after they run out. That's pretty inconvenient.
Sony doesn't give you a break on glasses for the kids either. Whether you're buying for the young ones or for adults, you'll be paying $150 a pair. And of course, if your TV doesn't have a built in transmitter, you'll have to pick one of those up for an additional $50.
