"Ears" are not electrical, they don't use battery power nor do they require wires. They won't fall off, even when the tablet is jarred, or turned upside down. And because they are small and lightweight, you can keep them anywhere.
The company behind the accessory is seeking $5500 in crowd-sourced funding, and so far has raised $3189 with 21 days left. You can pledge $10 to receive a pair of "Ears" for the Microsoft Surface RT/Microsoft Surface 2 or for the Microsoft Surface Pro/Microsoft Surface Pro 2. The Kickstarter funding period ends April 28th.
For those with a Microsoft Surface tablet,"Ears" could be the perfect low tech solution to the volume problem that afflicts the speakers on Surface tablets. "Ears" come in a variety of colors to match the Microsoft Touch Covers, and you can see them in action by checking out the slideshow below.
