The CordCruncher is one of those gadgets that seems useless when I first read about it but think it’s pretty cool after I’ve had a chance to use it.

There isn’t much to it: a set of earbuds whose cord is encased in an elastic sleeve. But the cool thing is that it stretches from 16 inches to 3.5 feet and stays tangle-free the whole time.

To stretch them out, you carefully extend the earbuds out of the sleeve and to retract them you just hold both ends of the sleeve extended and the headphone wire shoots into the sleeve.

Then you can just roll it up in a ball and you’re all set for the next time you want to use them.

The company says the elastic sleeve is made from a hypo-allergenic material and it works very well to give you decent sound and to conquer the main objective: keeping the headphones’ cords tangle free.

There isn’t a microphone on the cord for hands-free calls, but for $20 they are more than worth the money, since you get the earbuds along with a cable management system.

LENSBABY’S GOT A NEW TWIST

The Lensbaby Edge 80 Optic is the newest in the interchangeable optics for the Lensbaby System. I tested mine in the Composer Pro.

If you’re not familiar with Lensbaby, it’s a system of lenses designed to capture a circle of focus surrounded by a soft blur and is available in mounts for most of today’s digital SLR cameras.

Unlike most of the other optics, the Edge 80 has a 12-blade adjustable aperture. The Sweet 35 is the only other Lensbaby with an adjustable aperture. The other have aperture discs you have to change for each f-stop opening desired.

What makes the Edge 80 different from all previous Lensbaby optics is it gives you a slice of tack-sharp focus through your image bordered by soft blur (instead of a circular sweet spot of focus).

I used mine during a portrait session: The look combined with the ease of changing aperture and moving the slice of focus made my session fun and easy.

LOGITECH CUBE MULTITASKS

The pocket-sized Logitech Cube is a multifunctional device that works as a mouse and as a presentation remote with a range of 85-feet.

It’s shaped, oddly enough, just like a cube, so it takes getting used to as a mouse. The Cube has a right-click button in the center and a left-click button up front. A USB port and a power button are on the back for keeping the internal Lithium Ion battery powered up.

As for presentation features, it was easy to flip through slides backward and forward, once you get used to which button does what.

For example, to flip pages backward you have to flip over the Cube while clicking the main button and you press the top to go forward to the next slide or page.

It also comes with a Logitech Unifying USB adapter to plug into your computer for a wireless connection without needing software. The Unifying receiver can connect up to six selected mice and keyboards at the same time. You can find specific information on which products work on the Logitech site.
