Did he really say or at least strongly imply that? I must have blocked it out of my memory.
Well, that's a bit of my hyperbole layered over his own. I figured why not just go all in with it, lol. What he said was his ear speaker had "cracked the code" and part of that is due to the 'recent' development of neodymium. I'm not sure how 'recent' is recent to George or whether he's aware how long neodymium has been used in headphones and IEMs other than his own. Here's the clip which you can start at 13:00 if it doesn't already.
The context was all IEMs produced to that point sound like shit and hurt his ears, and he was going to fix that using his latest and greatest breakthroughs for his ear speaker. Well, they did have one of the warmest and least extended sounds of any IEM I've used. George does have a 'sound' he is looking for with everything he does it seems to me.
