The vocalist(s) and main instrument(guitar or piano) were loud. The chaco sole is second to none if you suffer from low arches. Even then its not an easy target to hit. They arent transparent either, so I felt totally comfortable not wearing a gown or anything when I would go from the bed to the bathroom. Hope He can charge all three devices at the same time. I tried holding a wall anchor in pliers to see if I could get a screw to drive into it. I was pleasantly surprised with the quality of this product for the price, it’s lightweight, yet very durable. These are warm, solid, comfortable and all around grand. This one is by far my favorite. I use them to comute to work, 30 min walk each way.
