I have custom made ear plugs (the type the musician wear) and noise canceling headsets.

I find the ear plugs work best for "going out" or family gathering. I am able to talk with a small group of people and not hear everyone else. They work well when I am in town or around crowds of people.

Noise canceling helps around the house or at the store. I use them the to listen to books or music mostly.
