Hey, I still have a charging case and wanted to get new Track Air plus in-ears, I could offer you the new charging case, that might be a win-win situation ;)

Did you make it now because I have the same problem

As far as I know, this is only possible on the official Libratone website. But since Libratone is currently bankrupt, this could be difficult. MFG

I don't think so. I would ask the manufacturer or look on Ebay if someone only has a charging case.
