Off topic on bud’s fit - I think I finally got it.
I am trying 2$ silicone ear hooks from shoppee for LBBS and they hold them in my ears like crazy.
They seem to poke me a little physically making them a bit less comfortable than just foam (especially while laying on side of my head), but I can basically bang my head around with no pseudo seal being lost. That would make earbuds much usable on the go!
noticed the ones without hooks in the side bar and added already, already have tuning foam, probably should get more metal filters just because of wet earwax
Shopee is kind of local so I am not sure that would work for your country + the ones that Riku sent are probably exactly the same https://shopee.pl/product/545120974/10765494191?smtt=0.575514211-1651349278.9
One note, the ones without hooks does not work at all for me (they are in fact much worse than just foams). The trick of those hooked ones is that they press against the cartilage of my ear on reaction pushing the bud back. It is therefore positively mechanically locked by shape, not by friction
