One screw missing. Even too tinny for listening to audiobooks. I have warn them several times and they are so comfortable. I decided to use the tile on my second phone that I dont want to be notified if I leave behind. as expected. This hard shell has been a saving grace for. I tried stuffing cotton in the front to cushion my toes. This is the Topeak stand just with Performance branding on it (IOW, Topeak made it, Performance sells it under their brand). I tried them on my work computer before writing this review and found the sound quality to be just fine and the comfort to be superior. UPDATE 10/31/20: After using for several months, it seems the effectiveness has drastically lessened.
