I purchased these audio chips for my ski helmet and have been using them almost daily for the past 2 seasons. They sound as good as I need them to sound, answers calls with ease, microphone seems to work loud and clear. I couldn't have asked for a better set of audio chips and the low price is just a bonus. $230 cost from the nearest competitor compared to the $79 that I paid for these, I'll take that deal every time. They also come with some great customer service, I received a response to a question from them in under 24hrs. After 2 seasons of daily use the left speaker (happened only once) wasn't pairing with the right speaker, after instructions from the tech support, they work perfect again.
