Which earplugs have the best noise isolation? So far I tried Hearos Xtreme Protection (those blue) and Hearos Ultimate Softness. Just by looking at numbers of noise cancellation they should be pretty equal, but in fact are not. Xtreme are much better.
Can you name any other earplugs which have higher nose cancellation especially of lower frequencies?
The colour botters because everybody can see them. Are there any earplugs in natural colour but equal (or better) to Xtreme? Or can I just paint the outer side of earplug with some natural skin marker?
