Thanks for the reply! I tried that and everything was functioning perfectly. It does not appear to be the wiring.
What led to this in the first place was that I tried using them with my guitar amp but didn't see a headphone jack so plugged them into the 8 ohm combo speaker outlet, which was a rookie mistake. Perhaps I played it too loud because afterwards when I plugged them into a laptop to use them normally, the left side only works at about 25% of the right.
What makes it a bit more bizarre is when they are plugged into the amp (through a 1/4" adapter), the right side works perfectly fine. If I pull the cord out a bit, the left side works perfectly fine.
I mention this because the left speaker is capable of functioning at 100% capacity but only in a specific circumstance
