Re:Specialized earplugs? (Score 1)

I have musicians earplugs http://www.etymotic.com/ephp/erme.asp and they do the job nicely. They have to be fitted to your ear (an audiologist will make the molds and do the fitting). They knock down all frequencies evenly, so things sound the same, just significantly softer. I bought them for the many concerts I go to, but they have been lifesavers on airplanes, subways, and even while sleeping in noisy environments. They are expensive though -- look to drop $150-$200 on them -- but worth it.
