Please delete if not allowed. I know nothing about it bikes. My friend loves his R6 and I want to get him a really nice gift. He currently uses AirPods when he rides but has debated an audio system in the past. He likes listening to music. Does anyone have recommendations? I remember he made a comment about it costing like 1k but when I look into it, it seems like be closer to like $400/500. Are they beneficial to someone who usually rides solo?
