Don't know if it's poor finger skills or odd ear canals but have a hell of a time inserting earplugs, tried MANY types, use my stihl helmet, wore out my old lightspeed ANR headset mowing lawn, use earmuffs there. Lot of motorcycling, used inflatable earseal helmets for several years but they wore out and are NLA. A good windshield adjusted for proper wind deflection makes a huge difference. Wouldn't road trip without a windshield.
Anyways my point; Tinnitus. Many of us oldsters have it.
This is supposed to help

I pretty much DIY'd to the same result, seeing one of these threads has it return for a bit, otherwise I don't notice/hear the ringing.
