I used it for about 3 hours a day for 2 weeks after purchase. After that, I stored it in the box. I checked to see if I could hear the sound before listing it, and I think there were no particular problems. I have never used the microphone, so I don't know. There are no noticeable scratches, but there is some slight stretching in the rubber parts. See image 5. The separate microphone jack and headphone jack (Y splitter) are in the KEEP PLAYING box.
