Haven't ridden without them for the last, more years than I care to remember now, but always glad I did, riding without them is scary loud and that's wearing one of the quietest helmets I've ever worn, a humble Schuberth C4 Basic. Ear plugs are also the best ear cleaners ever. Remember one time, I put one ear plug on top of another ear plug mistakenly, in my right ear and pushed the first plug so far in; the wife had to remove it at the roadside with a pair of thankfully, thin nose, pliers from the bikes toolkit. Nurse! I kid you not. 
Went to the box of ear plugs we've been using for ages and it's nearly empty. Time for a new box, we use Moldex Pura-Fit Ear Plugs 7700 (Box Of 200), less than 2pence a pair, bloody brilliant things and don't worry, I can still hear around me fine while plugged lol.
What ear/hearing defence is your weapon of choice? Pardon 👂
