Earmuff hearing protection

I'm writing this review now because after a year and a half, they have broken on me. The break would be repairable if I had hot glue, but I don't right now. I can still wear them, but I have to hold the broken pieces together before I put them on. I did use them frequently and take them basically everywhere, so that might be why. The noise cancellation is good; when I don't have my glasses on, I get blissful silence. I got these because I am autistic and loud or "sharp" noises really bother me. Without my glasses, these completely tune out the neighbor's dog that barks all day long like no one loves him. Helps me sleep when there are noises preventing that. Also, if someone speaks to me while I'm wearing them, I can make out what they're saying, but all the "sharp edges" of the noise are gone, leaving a quiet and muffled sound that doesn't bother my sensory issues. This is, of course, *with* glasses. Wearing any sort of eyewear with these creates a gap in the rim that lets in a little bit of sound. It's not much. The only other problem besides the breakage is that they are pretty tight on my head. This might not be a problem if you have a smaller skull, but I'm not sure, they clamp down pretty tightly. They stay on well, but it's uncomfortable and can make my headaches worse, especially if I'm also wearing my glasses (because the earmuffs press the sides into my skull--if you've ever worn glasses and headphones I'm sure you know what I mean). If you are getting these for sensory issues, or for any other reason plan to use them often, I'd recommend looking for something higher quality that will last longer and be more comfortable. But if you only need these sometimes, I think they work just fine.
