Sometimes, it needs what seems to be a small, tangential innovation to make a product successful. At the time, it may not seem much, but it can result in the product acquiring a life of its own. One product which is making its way along that trajectory is the humble earbud charging case.
The history of the charging case is quite interesting. Stereo wireless earbuds were a long time coming. It needed some serious technical innovation by a couple of chip companies to make them possible – new technology by Cambridge Silicon Radio (now part of Qualcomm) to let them receive and render separate left and right audio channels, and small near-field magnetic induction chips from another silicon company – NXP to send wireless signals through our heads. It then needed the brilliance of a German startup called Bragi to turn these concepts into working stereo earbuds, kickstarting the whole hearables market. It has become the fastest growing technology product ever, eclipsing even the iPhone in its growth.
