I find the Hearos Hi Fi plugs to be very comfortable for extended wear, and they sound pretty good too:

Which is higher than the US, but you do only get one set of ears per lifetime. As someone who has chronic tinnitus and can't bear more than a few minutes of high volume music anymore, I really recommend everyone begin using hearing protection. And for the record, I'm convinced that 20 years spending 12 hrs a day around noisy computers has probably harmed my hearing as much or more than going to shows. At shows I've almost always had some sort of ear protection.
