These Bluetooth speakers are made out of recycled championship tennis balls

The best wireless speakers are portable, durable, and make your music sound great.

Richard Moss, CEO of the design studio Rogue Projects, knows from his experience as a designer and tennis player that tennis balls satisfy the first two criteria. And since some 230,000 balls get wasted each year after the Grand Slam tennis tournaments, why not also try to satisfy the third?

That's why Moss created hearO, a portable speaker housed in a tennis ball. Take a look.
