I have 2 sets of custom ones I bought at Sturgis. I think they were about $30 and really worth it. I rode without them for years but around 40 I noticed my hearing deteriorating rapidly. The ear plugs made a big difference! I can still hear my radio somewhat if it's cranked up
I don't use them around town but on the highway they are a life saver to me. I wear a half helmet as well.
As a bonus I wear them when shooting guns. Work great for that as well. Sometimes they are sold at gun shows in my area too.
