+1 to "get custom molded earplugs"

If enjoy and pay to see live music, you should spring for a set of "musician's earplugs". They're molded just like safety/sleeping earplugs, but they use a flat 10-15dB attenuating filter. They make the music quieter without distorting it.

Symphony players wear them because brass/percussion is loud enough to cause hearing damage with hours of exposure. I've sung in mine for Easter morning services where I was wedged between a celebratory trumpet and an organ with all the stops out.

They're not cheap, but they're not very expensive in the world of Ticketmaster fees.
