I use CVS Superior Soft Foam Earplugs ~ https://www.cvs.com/shop/cvs-superior-soft-foam-earplugs-prodid-942245 https://www.cvs.com/shop/cvs-superior-soft-foam-earplugs-pro... .. nothing really fancy, though maybe the nicest ones that most CVS' sell. Sometimes, I will experience minor discomfort if I've pushed them too far in my head, but pulling them out just a little usually relieves any problem. I've had them in all day (again), only taking them out once for a long conversation I had .. and I sleep with them too. Honestly, reality in a city, IMO, is by & far way too noisy. And I don't think from an evolutionary standpoint, we're super-well-suited for processing (consciously or not) all the different directions of noise washing across us .. Or maybe I'm just too easily distracted/overwhelmed ;)
