I have finally entered the world of true wireless headphones, after much refinement. I started with j b l airpop go and now I have Skullcandy Indy Evo. I prefer the sound on the jbl, but I prefer everything else about the Skullcandy. They stay in my ears, and have easier controls. They both have product registries and an app. Based on the reviews I read before I bought the skull Candies, having an app is a big deal.
