In any case, it's irrelevant - as far as I know, wearing headphones or earphones while driving a motorcycle is illegal whether or not you happen to be playing music in them, because how would anyone else know? If you get in an accident and get charged with distracted driving, that's on you. If you want earplugs, just wear them. They're much cheaper and more effective than sound cancelling headphones if you genuinely just want to block noise.
One risk is your focus going from what's on the road to what's coming into your ears.
This may have some useful mental aspects if you're doing a long-distance drudgery ride down Route 66 with nothing much happening in between pitstops, but it's another thing on I-5 or I-95 with all sorts of chaotic lane changes going on.
Even speaking with passengers has been shown to increase traffic incidents:

It's a debate spectrum / sliding scale on how society wants to go, but at the very least one should be aware of the risk factors and be mindful of where your attention is.
I am a bit stunned reading this.. Is this a common perspective of motorcyclists?
Like all things it does depend on where you ride and the general driving culture. In America that’s how I ride but in Vietnam it’s very different. Road rules are not as often followed and honking is common to make yourself known, usually while there I wear lower db reduction ear protection.
I am also not saying that there is zero opportunity to hear a horn but already on a motorcycle you have to have so much more awareness that I don’t find that sounds are all that helpful. It absolutely applies to driving a car too, after driving a motorcycle for a while I am as shocked as you just how unaware drivers are of their surroundings.
Keep in mind at around 35mph you can easily hit 85-90db from the wind. I do think ear protection actually helps identifying sounds but I still argue the hearing part is not that helpful.
I am not trying to say you have to follow my methods but folks calling for criminal punishment and shaming are a bit too far as the safety benefit from hearing is quite minimal depending on the driving culture.
No.
For example, every beginner-advice thread in /r/motorcycle has a highly-upvoted comment(s) recommending ear protection, including many folks stating they wish they had started using it earlier.
And even if it is conceded that sound may not save you from other vehicles, ear pro(tection) reduces the health risk of hearing loss that would effect other aspects of your life.
Cars are quieter, and hearing other vehicles is more likely. If anyone shouldn't listen to music, it's car drivers, not motorcyclists.
