That was actually going to be my suggestion.

What you described happens if the ground connection to the headphones becomes disconnected.

Remember that electricity requires a 'loop' to flow. You would think that, without the ground connected, you wouldn't hear anything, because there's no loop. What it actually is that electricity flows from an area of higher voltage to an area of lower.

But the L and R side headphones are connected at the ground point. Without a connection, the headphone's ground connection will "float."

If you play a mono sound, the voltages on the L and R sound will be the same and you won't hear anything. But if sounds are played through L and R are different, electricity will flow the one headphone, into the other through the ground connection, and out, because the voltages are different. So you will only hear the DIFFERENCE between the L and the R.

What's almost always in mono? The commentary voices. What's almost always in stereo? The game. So, you only heard the game. In music, the result is often kinda creepy and echoey and missing the vocals.

Weird, huh?
