The ball acts as a smart, bluetooth controller. It connects to the companion App which then reproduces the sound.
We did think about having a speaker in the ball at the beginning, it would have been super cool.
However, since the sound quality could not have been really good and durability of it would have been a challenge, we decided to create a companion App.
We believe this is much better, since you can stream the sound to any speaker or headphone, so you can have super good quality sound and loud volume if you want, but also because it makes it possible to have many more different experiences playable with the Ball.
