Moss says he wanted to design a speaker that was easy to use and looked great.
The speaker uses just one button as its master control to connect to phones, tablets, and computers.
The latest versions are in honor of Wimbledon Memorabilia Week.
The company will be releasing speakers signed by tennis players Andy Murray, Ivan Llendl, Michael Chang and Lleyton Hewitt.
They will be sold exclusively through Kickstarter.
Each hearO comes with a charging cradle and storage canister. For about $7 more, you can customize your hearO with a specially colored ball or engraved canister.
The ball also comes in lime green, red brick, choco brown, and dark brown. Of course, if you choose to keep it old-school, you can stay with the original yellow design.
No matter its color, each ball comes from a Grand Slam championship game.
Ultimately, Moss hopes hearO can achieve a couple goals at once.
As a designer, he wants to think beyond the typical autograph or framed photograph and create an entirely new category of tennis memorabilia.
But he also is thinking sustainably, hoping hearO will help cut down on the massive waste from discarded tennis balls.
"We hope that with each ball's story, hearO inspires, and that this ball gets its chance to live on," he says in the Kickstarter video.
You can buy hearO for about $60 through Kickstarter. It comes with the cradle, micro USB cable, and, exclusive to early backers, a customized holding tin.
