Interesting that this is marketed at being a cable made for the Rockboard, "flat" so that it fits through the hole unlike a regular XLR. They do, but you have to push, and I mean push, very very hard to get it through the hole. It is a very tight fit indeed, and you do feel like you're either going to damage the board or the plug pushing it through. Board is a Tres 3.1 bought in December, so a current model. Very strange. Otherwise, cable appears top notch in quality.
