Windows 10: Earbud case replacement

I have lost my earbud case charger. I don't how to but that item separately and how to get connected to Microsoft support in France.

[Solved] Max sound level is insufficient for earbuds

My thanks to you both for the explanations.
The earbuds are wired cellphone earbuds, with the speech switch, but no volume control. It is plugged in the back because the front sound connection is still AC97.
The case is a 12 year old Antec and it's so versatile and (heavy) that I didn't want to give it up. So far, haven't decided which of my options to start with, based on ascending cost.

1. The wiring schematic is on the web, and is very clear. I also have the electronics to check out the kit I bought.
2. Buy a 3.5" or 5.25" panel inserts with the USB 3 and sound connections. I have both available.
3. Contact Antec for the replacement part.
4. Buy a new case.

And after this is resolved, buy better quality earbuds.
Your comments are most appreciated.

Is there a replacement for the earbuds for the Samsung Focus?

The earbuds that came with my Focus are starting to go and I'm looking for a good replacement. It's hard to find something that will work with the Focus. I need something that I can use the microphone and volume buttons with.
