They come with extras too, just in case they break off...of course I lost them, so woe is me.
I constantly opened and closed my plugs when I was bored. Ended up breaking off the headphone one. Luckily it came with those replacements (and I knew where I put them, lol). So if you do go with the Ringke, just don't play around with the plugs that much... They're on there pretty good, but I guess there's only so much they can take.
I just received my Rinkge Slim case and it is thee best Slim case I have ever had for a phione. I never thought for a reasonable price you could get a case so thin that did not feel cheap. This thing is tight fitting and has enough space for the stock extended battery. It simply feels like it is still a naked phone no joke.
