Well, not as well as I’d hoped. I went to a middle school basketball game last night, which really wasn’t that loud. They definitely block out the sound, but if I wanted to hear what my wife had to say, I had to take one out. They’re just earplugs. They’re not magic. But Christmas will be the real test. I might take them AND my AirPods. Using the noise cancellation might be better. IDK.
