Replying to The State of Helmet Audio

I have had Giro Tuneups, RED audio kit and Bern Eight Tracks in the last three years. None of these have made it through a complete season. Why does helmet audio suck, or can someone tell me a positive story of their helmet kit working for a few years. The RED was the worst, the Bern sounded the best but shorted out in a couple months. Giro tune ups seems to be solid but they cut out my last few days of the year and started to crackle.
