But he was fed up with headphones because they wouldn't stay in, sounded awful or hurt his ears. Kyle consulted audio engineers, material specialists and high-level athletes to develop and test hundreds of designs, formulas and prototypes in order to create an easy and affordable custom molded earphone. In February 2012 Kyle created the worlds first thermo-fit custom earphone and Decibullz was born.
