One of the greatest inventions of this gadget era is Bluetooth. For the uninitiated, Bluetooth is technology that wirelessly connects one device to another. Why do I love it? Because of the safety factor. I have a Bluetooth headset that I nearly always wear when I’m driving. That way, when I get a call on my iPhone, my eyes never have to leave the road.

Finding other ways to do that is a great idea. For instance, check out these Oakley ROKRs. Oakley, as you probably know, is a premier — maybe the premier — name in sunglasses. They have outfitted a number of different types of sunglasses with their own Bluetooth receiver.

All you need is an adapter that attaches to your MP3 player or cellphone/smartphone, and voila! Your shades become part of your wireless world. Of course, that will be good for more than just driving. Running, biking, hiking, anywhere you wear sunglasses, you’re connected. Buttons on the ROKR allow you to adjust the volume or change songs, freeing you up even more to concentrate on what’s ahead, rather than on fiddling with a gadget.

Oakley claims five hours of talk time and about 100 hours of standby time before needing a recharge. And if their sterling reputation for making sunglasses (I’ve owned several pairs, with no complaints) transfers to the ROKR (which is actually made by Motorola), it looks like a fantastic package.
