I just realized my headphones had a volume button after 1 year
Is there a reason you missed this?
I was stupid enough not to check the guide until right now.
Finding out how your headphones work should be done by reading the manual when you first purchased the electronic device. When you don't read manuals, you end up wasting alot of your own time and energy.
I am an engineer I thought I knew everything lol.
It happens to the best of us. I recently learned something similar. It is good to laugh about a mistake.
