Ceretone, born on Indiegogo, hit the scene last year with impressively tiny hardware that still remains one of the smallest and lightest hearing aids I’ve ever reviewed. At just 0.96 grams each, the Ceretone Core One were so light they threatened to blow away in the wind. With a price of $349 per pair, they had a similarly minimal effect on your bank account.

The trouble with the original Ceretone Core One is that they just weren’t very good as hearing aids. They were not tunable, suffered from occasional feedback and interference, and could be controlled only via a rudimentary mobile app. More than a year later, Ceretone has emerged with an update in the form of the Ceretone Core One Pro, and they feel like a full reboot with little in common with the original product.
