Very comfortable and flexible sandal/ trainer, best choice for summer to use in park or at beech. The case comes is solid and the zippers look study as well. I need to be able to hear things around me and even with both in I can indeed do that. Comfort - Huge fail. meaning I wont throw them on the floor in the back seat and realize my son returned to school in that car, with my shoes! I just cant get on with the toe-post type of flip-flops, so these are my only option. The fabric is thick enough to make them family friendly without a robe which is great for the humid summers. TippTopp Zufrieden. To be honest, the 650BTNCs are by far the best sounding wireless headphones in the $200 price range. Very comfortable and perfect lock down attire.
