I use my xperia ZL for music on the go now, and because the interface on that is much better and plays FLAC (reason I got the cowon), I noticed my s9 stays at home untouched. There are no problems with it besides cosmetic damage I just noticed prior to posting this ad. I had a flip cover case on the cowon since I got it, and the plastic sides got pressed hard and they look like micro cracks in the plastic but im unsure whether if they are real cracks but a couple drops of super glue should fix it up if they happen to be. Asides from the slight cosmetic damage along the sides, the glass is in excellent condition and there are no problems.
Feel free to message if you have any questions !
