I use the foam ear plugs. Have them in many colors.
Before you insert them in your ears, wet your hands with anti bacterial gel, roll the plugs in your hands. Allows plugs to slip on in and provide a tight fit.
Too late for me. Trying to preserve what hearing I have left. IMO, you ride a Harley for 20 + years, your hearing will need to be digitally enhanced. Good news is that good digital hearing instruments are no longer $10K; now $2K at Costco.
