Just reading the comments of this video made my day 🤣

The bottom speaker on my phone is Right and the top speaker is Left. I definitively know which rotation direction is the correct one now.
Neat!

Hahhaaahahaha.
I’ve used this for years to test speakers and headphones etc, and had never read any of the comments!
They’re great! But you can feel the disappointment dripping off some of the comments, that made me a bit sad 😔
