I've heard both at different times, even though Laurel is the more common one. In fact, at one point, I figured how to mentally switch between them, but it's sadly not something I have been able to replicate since then.

Both. If I think Yanny, I hear Yanny. Likewise, when I think Laurel, I hear Laurel. Try repeating it in your head for a couple of times and listening to it. Once you are able to switch between the two, it gets easier and easier to be able to do so and hear both

It has both words in the recording, was revealed that they recorded both words, but at different pitches, so some people pick up on the higher sound while others pick up on the lower sound frequency that was used
