Ear plugs that work.

I love these things. They seem to filter the most annoying range of sound but still allow traffic sounds. So light, it's easy to forget they're in place.
Ordered from Amazon.

I have a pair of these too and they do work well. the 20db rating isn't quite as good as I was hoping. So I bought a pair of these:

Claiming 27db rating, these seem to do just a little bit better.

Not quite as well as the 30db foam plugs, that tend to muffle TOO much.
