Addendum - After 5 months the matte coating is peeling off the lenses. I tried to contact support but they didn't answer. Deducting a star for the quality and lack of customer service. Everything else about the glasses is still good. I've been using them for a few months now. I mainly use them to listen to podcasts and audio books. The sound is good enough and loud enough. It's not the best sound quality, but for the price they're the right quality. The batteries last many hours. Good quality sunglasses.
