The brass/gold RE800’s build quality is great and I can’t say anything bad about it. You either like or hate the classic box the RE800 comes in, but the monitor itself just feels qualitative and oozes luxury. It sits perfectly in the ear, doesn’t draw too much attention and guess what, it also sounds incredibly good.
