Induction (Wireless) Charging Earbuds

I finally had time to make mock-ups to see if the battery would pull the earbuds out.
The earbuds stayed on when it had a wingtip or an over the ear hook feature.
So from there I made 3 battery charger (A-C) concepts and 3 earbud (1-3) concepts.
Any opinions on a winning configuration?

For example configuration 1/A or 1/C wouldn’t work as the earbud would fall out, but 1/B could work.
