Announced some two months after the Onyx one, the OnePlus X Champagne arrived at our doorstep amidst the whole CES clamor. We did find some time for a brief hands-on experience, or more like eyes-on, as it's essentially the same device as the black OnePlus X we already had for review. As such it's not to be confused with the OnePlus X Ceramic, even if your idea of the material is more in line with the Champagne's color scheme than the black of the actual limited edition version. OnePlus X Onyx Black next to OnePlus X Champagne Anyway the OnePlus X Champagne replaces the black glass panels for white ones. On the back that means that fingerprints aren't as visible as on the Onyx model, when they inevitably start accumulating. On the front the color scheme makes the capacitive buttons stick out a bit more - apparently gray on black doesn't provide as much contrast as champagne on white. OnePlus X Champagne And champagne is what OnePlus calls the color of the frame, which has the same 17 micro-cut grooves as the plain steel-colored one of the Onyx. Some call it champagne, others call it rose gold, then there's the occasional peach interpretation, but the bottom line is that the combination between the frame and panels really works and the phone looks stylish and expensive. The OnePlus X Champagne is available for purchase right now, provided you have an invite. That is, unless it's Tuesday, Tuesdays have historically been treated differently by OnePlus, and invites aren't required. It goes for $249 in the US and 269 in Europe, because that's how currency conversion...
