This is the case for the SONY WF-1000XM4! This is an auction for the case only. The light doesn't turn on, so I can't confirm if it's charging. Since the operation is unconfirmed, I'm selling it as junk. Please consider purchasing it for parts or repair. Please consider this item with the understanding that it is junk. If you are looking for a product in new condition, please refrain from purchasing.
