I'm waiting for mine to arrive. Their biggest selling points for me were that they are a collab on already popular iems, that Zeos didn't try to be someone he isn't and didn't ask for a significant sound signature change, the red and blue colors are a HUGE feature and the neckstrap should be a very useful thing too. Such an approach immediately earned him 100 levels of respect in my eyes. The guy clearly knows that he's an entertainer and not a golden ears guru, and he managed to find and address important issues which are usually completely ignored. I don't even know if I will like the sound of Z12 at all, yet I am absolutely sure that I will keep them. As a great example of how you don't always have to be a super-professional in order to improve a product. I'd also suppose that the real profit for him will come from those neckstraps and the limited edition Z12 themselves are technically just a smart marketing move in order to introduce them.
