I mean.... I wear constructing/shooting range earmuffs sometimes and I found that helps to concentrate, and also wearing them when sleeping produces a noticeably deeper rest. Great for noisy hotels. Not so sure about this system, though, unless maybe I had to nap on the street in a warzone or something.
Sometimes I’d wear earbuds underneath the earmuffs. Other times I’d just prefer as close to silence as possible.
I tried noise canceling headphones and couldn’t tell if they really helped. This was a while ago, like 2009, but I bought some decently high end Sony and I felt like they made my ears ring later on. It seemed better to wear earmuffs vs. some special high tech method. Plus one thing I was mitigating was the meows of a huge cat I had who meowed REALLY loudly, and that’s the sort of thing noise canceling doesn’t reduce.
Is it me or does that air tank look pasted over and the breathing tube too short for practical use? (turning his head left would drag down the tube on top of everything)
