This is a common comment you see on
Youtube videos, whereas the video only projected sounds on the left headphone. Only headphone users experience this.
This is also a confirmation that your
headphones is NOT broken. Many people think it's just them, but when they scroll through the comments, they see this one
particular comment and relieves them.
Example
Scenario:
*plays a video*
Why is
the sound only at the left ear? Is my
headphones broken already?
*sees this one comment*
"My left ear enjoyed this video."
Oh, guess it's not just me.
