Here's some pics.
It's definitely a fake, but good effort. I may get one...
I notice the speaker grill cut-outs are less than the "real" case. Also, the leather grain is much larger than the real thing. Most likely leatherette?

I bought this case and received it during the weekend. Although it looks real, the ports don't align perfectly, especially the charging port. I have to take it out of the case to charge it. Also the headphone port is a little off too. I bought two of these, one for my girl and one for me and her cutouts were more accurate than mine so it might be just mine.
Based on your pics the charging port looks the same size as the real case. Did you have to do any sort of mod to the port areas to fit your headphones?
