I enjoy music and loud concerts and when I go I use Etymotic ER20 High Fidelity earplugs. So much better than foam because they evenly cut the spectrum rather than just the high end. Now, Etymotic has the XS design which is stemless and allows use under helmets. These are supposedly good for racers or riders who want to hear what their bikes are doing, revs, tire chatter and so on. Someone who races should try them.
