I'm a listener from Lima, Peru, and I love your podcast. In episode 71, you said that you use hearing protection when you go to the movies or concerts. What do you use, specifically? I am very concerned about protecting my hearing, as I have a relatively low tolerance to loud sounds, compared to other people. I tend to cringe and almost feel pain when I'm in loud environments, more than anybody else. But I like music, so I bought a pair of in-ear monitors (Etymotic ER4s) some years ago. I like the isolation so much that I sometimes leave them in my ears with no music, just to hear nothing.
I recently ordered a pair of ER20 "high fidelity plugs" from Etymotic, a universal-fit, low-cost option ($12.95) that the company claims to reduce sound by approximately 20dB in all frequencies. Have you ever tried them? I have also ordered a pair of custom-fit sleeves for my ER4s from ACS Custom. (When I was in the US, I went to an audiologist for my ear-canal impressions.) Because I had my impressions taken, I can also order a pair of custom-fit plugs with filters. However, they are more expensive ($185). Do you recommend the custom-fit ones?
