Motorcycle Ear Plugs for Wind Noise Reduction, 2 Pairs Reusable Motorcycle Accessories - Moto Earplugs, Soft Comfortable Hearing Protection for Motorbike, Touring, Racing, Riding - 25dB, Biker Gifts

https://a.co/d/02Sk83cb These are the ones I bought and they work really well. The trick with almost any earplug is to figure out how “hard” you need to push them in for the optimal amount of sound. If I’m cruising around town, I only slightly push them in, but I push them in all the way when I take highways. You can hear engine, cars, horns, and most other things with these. Plus you get two pairs of them.
