I bought these for myself, I am a petite older woman. Use these when I use my leaf blower and weedeater. I would say they cancel out about 85% of the noise. As I said I’m small but these must be small too Because if I were them for very long I get a headache and the fact that they push in on my ears. But they’re the first ones I’ve ever had so I have nothing to compare them to.

sound cancellation/muffling is great, my dog has a barking problem and his barking causes me a lot of pain since im autistic and am sensitive to loud, sudden sounds. i used them today for about 30 minutes since my grandparents were moving stuff and didnt want my dog to get in the way so he was locked in my room with me. barking and whining nonstop for the whole time, and i wasnt bothered one bit. they do get a bit uncomfortable after awhile though, especially when eating. otherwise, great…

Very comfortable and block noises. I use when I use the leaf blower outside and vacuuming in side. They work really well.
