100%. I got my custom concert ear plugs right before Sonic Temple 2024 this year. I forgot them on day 1, and everything was painfully loud.

Days 2-4 were wonderful. I could get to the front of the crowd with absolutely no discomfort. Plus, wearing them for 8-10 hours didn’t cause any pain or soreness what so ever (off the shelf ones hurt me after ~30m).

They’re not cheap, but neither are hearing aids.
