Hi , my name is Tiffany McCoy. I am a regular listener of marching bands and I am a fan of marching bands. I have attended many marching band's live shows. But now I have a little hearing problem due to the loud beats there. So I use earplugs to protect my ears as advised by an ENT doctor and benefited a lot. I recommend that you use this earplug when you are in a very loud place to protect your ears.
