I have used the Surf ears 2.0 and were the best "standard" ones I tried because they are the most customizable. I ended using them with quite a different setting for my left and right ear, and this shows the need for plugs to be customisable for a lot of people.
But I quickly went to the ultimate: custom plugs molded to your ear with a kind of goretex vent added to them for keeping a good hearing and balance. This is not cheap, (more than 170 euros), but the fitting is perfect, no chafing even after hours of session, no stress points, and they sit against a wide part of the ear, so you can fall flat on your ear at high speed without any worries, which is invaluable for foiling or hollow waves. I started wearing earplugs after piercing my eardrum on a wipeout, and reaching 50% exostosis.
They are "aquason"
