In continuation of this post, I bought the "Ultra" earplugs just for a laugh, because in this world, when they say New And Improved, it's usually not so much. (For example I recently tested Sony's "Clear Zoom" technology, stated to be closer to real optical zooming than just another digital zoom. Guess what it was much closer to? In fact barely distinguishable from? Yep: digital zoom.)
So last night a neighbor played music louder than usual, and I put in my usual plugs. But as it turned out, at this volume they could only handle most of it, not all of it. I was still distracted.
So I thought, hey, this is the perfect chance to test my new "Ultra" plugs. So I did. And lo and behold! They were better! Music... gone!
(In the spirit of my slightly OCD sense of accuracy, it was 99.5% gone. So, 'virtually gone', good enough for me.)
I also tested it with the indoor air con unit in my bedroom: same thing. The normal plugs had never been able to handle all of it. But the new ones: (virtually) gone! Way kewl.
