If you are the kind of person who would collect championship tennis balls, these ones do double duty as Bluetooth speakers. HearO are wireless speakers that are housed inside discarded Slazenger tennis balls that were used in iconic tournaments. The living sports memorabilia takes the form of an upcycled tennis ball that has been given new life as a high performance speaker.
The retired championship tennis balls are often signed by greats like Roger Federer and Novak Djokovic as well, giving them even more value. HearO offers one button connectivity and an "intrinsic handheld nature" that makes it the ideal portable media player.
This gives a new functionality to collectible items that tennis fans will surely appreciate.
