I think earplugs require for who need hearing protection while riding, swimming, industrial work and so on.
Welcome to the forum. If you value your hearing and want to avoid the insanity that comes with tinnitus caused by wind noise, I suggest you do some serious research on the topic instead of asking for people's opinions. (Excuse me, outside paramedic voice again.)
Being a rider for many years of bikes with loud pipe I went thru plenty of plugs to find ones that did a good job all around.
Check out "Ear plug store" they have a plug called Surefire Sonic Defenders for about $10.00 . Normal sounds are not blocked ,like voices, but the sudden sounds and loud ones are blocked. We even use for shooting with the little end cap installed. I bought a dozen and hand them out when on a ride. Great for cutting unwanted wind noise.
Wait this is not a add for the Ear plug store because I must admit now that I ride a wing my plugs are no longer needed . Except maybe they would help with the road noise from this Dunlop front tire.
I'm guessing an E3 BB I just put on an E4 and will see if she's any quieter.
