Why is one of my MIFO earbuds not working?

My issue seems to be poor contact between the electrodes on the earbud and the case. This is not due to the electrodes being dirty, but instead it's due to the shape of the earbud and case. Perhaps it's a poor manufacturing tolerance, but when I place the earbud into the case, it has a very small amount of wiggle room. Depending on how it's positioned, it'll either connect and charge or not connect at all. The left earbud seems to work just fine in the case, but the right one usually doesn't charge unless I'm pushing it a certain way.

I've pretty much resorted to placing a tiny wad of paper towel in the case along with the earbud to help it into the position it needs to be to make contact with the electrodes and charge. The built-in magnet just isn't pulling it in properly. Later on, I may try putting a dab of hot glue or something as a more permanent hack instead of fumbling with the paper towel wad.
