We've been waiting for the next set in the series of Sony's top-class active noise-canceling earbuds for a couple of years at this point. Sure, the WF-1000XM4 came out great and continues to be great with multipoint support added through a software update. But we haven't seen too much movement on what we expect to be the WF-1000XM5 - just some pictures coming out of American regulators in March. Well, we just got hold of another couple of breadcrumbs.
