How do you "cover your ears?"

I can hold a free-standing handstand with my legs straight etc.... but then I remember that I'm supposed to "cover my ears." I just don't understand this concept... if I duck in my chin I fall over every single time. How do you "cover your ears?"

I found out my shoulders were sagging lol. I didn't have them up.

Edit: apparently i can't link the video... Gotta say... I think I need to start over hand stand training because I've had the wrong form for 6 months!!

2nd Edit: The difference is so astounding that my family knows the difference between the two forms!
