Claims to support WH-XB910N, but doesn't.
It's the right physical size, and the plug is the same. The headphones power on and report about 60% charge, however, when you plug in the USB, the light comes on for about 2 seconds, and then starts to blink, and refuses to charge. So despite XB910N being listed as supported, the charging system seems to be incompatible.
