The sound is clear and the microphone works well and blocks out all of the outside noise. I scrapped the heal of mine on some brick steps and was quite disappointed when the overlay scraped off. Very juvenile start up for book one. I always find Birkenstock sandals very comfy, they never run. I have a pair of 7 year old Teva sandals so I knew to order a size larger than I would normally wear. I cant even seem to find that there are even different versions.
