When we were prototyping our custom units with experienced users, one of the main complaints was that custom In-Ear Monitors are usually too brittle. Often a single drop of the custom In-Ear Monitors will cause a crack and in some cases even pieces to break off. This exacerbated by the higher costs of making customs and the fact that musicians move around a lot meant that custom In-Ear Monitors would break often.
We wanted to correct this issue so that users of Stealth Sonics Custom In-Ear Monitors do not have to keep replacing broken units. After many tests and trials, we developed a superior lacquer that provides a much tougher exterior. Based on our tests, it withstands most falls that are of normal, should height. We even did a drop test at over 2 storeys and still our shells passed the test.
