H-ears what I have tried. Right now using the orange ones that I cut down. The two sets of purple ones are home made starts soft and then sets, the bigger set cut out the most but I can not get my helmet on with them
the smaller set were perfect when wet but once set and put back they leak sound, because they are a perfect fit and need to be a tiny fraction bigger to seal.
The Pro Docs sounded just what I needed but just don't fit well enough to block sound.
I forgot to add in the picture the pack of silicone wax ones I mentioned.
I have just ordered a pair of 3M push ins that come on stalks that I intend to cut off so I can get my lid on.
My problem is too much wax - or rather I have the correct amount but narrow ear canals and one that is bent ! so shoving a plug right down is not an option as that pushes any wax onto the ear drum.
