I am going on a 4-day 2,000 mile trip back to Wisconsin with my dad in 6 days. We are staying in a hotel each night after long days of driving. My problem is my dad snores louder than any human being. I sometimes can't sleep at home when he's in the NEXT ROOM and I have a FAN ON. My dad suggests those shitty foamy ear plugs that don't work at all.
My question is, where can I get GOOD earplugs that actually work? Or headphones/something I can wear that actually blocks out sound really well?
