I’ve wasted plenty of money chasing a solution for this but always come back to foam plugs being the best for me. Every ride.
I just bought a set of the 200 Pairs Moldex 6604 from Amazon to hold me over until I die. 😇Highest foam NRR I could find, still lets in Sena audio, keeps my already bad tinnitus to a dull roar. 10/10 every ride
