Then your first entry was a little bit misleading, as you pointed to the cables, because they only work with the modular earphones .
The one you are searching for were only bundled in France because of the local law, the FP3 normally didn’t have those ones and as far as I know, they were never sold separately.
I would actually encourage you to just post a new search (also in Market > Buy) with a photo of the earbuds you are seeking plus a few words explaining that it’s the France-only ones you mean. I’d also mention that in the search TITLE.
I think a lot of French FP3 buyers might still have these lying around somewhere and probably hardly or never used. So I think your chances aren’t that bad!
Here’s a photo that shows the France FP3 earphones:
