GBA Earphone Adapter (Good Quality?)

[howston]

Hopefully someone can help? I have my original 3.5mm earphone adapter that is starting to wear out, so have tried to buy a replacement, but all seem to be cheaply made alternatives with loud hiss, and clicking/beeping sounds drowning out the audio of the GBA.

Does anybody (Preferably in Europe) know where to source a good quality GBA 3.5mm earphone adapter?

As far as I am aware the adapters should just be a straight through adapter no smarts or other signal bothering particularly necessary.

Though looking around you are not the first to decry the quality of modern replacements.

I should also note the GBA itself, and even more so flash cart, might be at fault. https://gbatemp.net/threads/fitting-a-ground-loop-noise-isolator-into-a-gba.602212/
https://gbatemp.net/threads/gba-speaker-noise-fixed.450093/ is for the original GBA but best to include it in this.

What I am more here to say is can you fix the existing one -- wearing out is typically going to be the 3.5mm socket aspect of it probably losing spring tension and they sell those all over the place (assuming you don't just gut a 3.5mm extension you have sitting around)
