Every year, hundreds of thousands of championship tennis balls are retired, but the English start-up HearO has reimagined these leftover tennis balls turning them into a meaningful product.

Working on the ball shape and its design constraints, HearO has developed these bluetooth speakers in collaboration with European designers and engineers, specialising in rubber cutting (the English Woodash Group) and in audio engineering (the French Innov8), and launched them with a Kickstarter campaign.

HearO works with used tennis balls from different tournaments, such as the american US Open (2019) and the Roland Garros (2021), every one bearing the authentic tournament logo and manufacturer, such as Wilson, Slazenger.

A limited series for their Kickstarter campaign has been proposed in collaboration with the Wimbledon champion Pat Cash, while Djokovic and Federer have signed a one-of-a-kind speaker each.
