I’ve been using the 20$ musician earplugs you find on Amazon. They’re cheap enough that If I loose them it’s no big deal and they have a natural flat freq attenuation. They claim something like 20db

This record rips and still holds up. Saw them open for Rage back in the day and was blown away.

If you need any Python QA test automation help I’m happy to invest. Thanks for the new home.
