In February, a blurry, grainy photo of what appeared to be a prototype of the new WF-1000XM4s was leaked, but over the weekend additional images were reportedly discovered and shared by The Walkman Blog which revealed the new wireless earbuds from every angle—both the left and right side versions—as well as their updated charging case.

The most obvious change is that the new WF-1000XM4 wireless earbuds are much smaller than the WF-1000XM3s, and presumably lighter as well as a result which should make it easier to actually keep them in your ears.

It’s also been rumored, based on leaked illustrations detailing a Sony Xperia smartphone’s battery sharing feature, that the WF-1000XM4's charging case will support wireless charging, a feature found on many other high-end wireless earbuds at this point.
