Excellent sound quality with foam? You must not be terribly
discerning as they are FAR from flat.

Earplugs are not so much about flatness, because if it is some 6 dB
above the resultant elevated threshold, then the brain can make use of
it, it comes with a neat autocorrelator and eq ex works just because the
frequency response of its sensors can vary so much. Read a recent follow
up of mine in a similar thread in alt.audio.pro.live-sound ....

As for ability to reduce SPL, they're hard to beat no doubt, but it
comes at a cost of severe coloration.
