Thank you in advanceI have a couple different set i am using. I posted a picture of the ones I am using on my Maria II a page or so back. These two are both obtainable from Aliexpress:
When I get home from work, I will try and dig up my order to send a link.
Maybe the right one is tight enough for the narrowest part ?
About the left one : do you think an earbud could fit inside covered with thin foam ?
