I hear both. I hear a higher pitched Yanni, and a lower pitched Laurel. It sounds a lot like Yelly actually.
I can only really hear yanny. At the end I can hear a kind of growl like "el" like the end of laurel but that's it.
It's been explained already, like the dress was.. my lawd people get confused I personally hear Laurel The sound is actually both layered ontop, that ASAP vid explains it, younger people who hear higher frequencies more will hear Yanny first or more often, older people hear Laurel. One time I listened it somehow transitioned from Yanny to Laurel, but as if Yanny faded away while Laurel kept going fokin internet
