I just got my Sabbat E12 Ultra, blue camo version today. It does have wireless charging even though it's not mentioned on the box. It doesn't sound much different from the dud original E12 I received a while back. The eartips are much better than the originals. Bass is much more balanced though maybe slightly slanted right, but bearable (as with my Jabees Firefly Pro). Mids and treble still seems stronger on the left side though it seems to be only noticeable in songs with peaky percussion. Either I'm unlucky second time or people are just oblivious to it. If all else fails I might just tap foam on one side.
