Any DIYers can troubleshoot why my entire left IEM is lower in volume than my right?

So, first off, I'm not using a DIY IEM, but I figured that the knowledge of DIY people can help me figure out what might be wrong.

I've got the Westone W60s (6 BA drivers in each monitor). It was plugged into a DragonFly Red DAC and one day I think I dropped the tablet computer that it was all attached to and I noticed afterwards that the entire left IEM was lower in volume compared to the right.

- I put it through a tone generator and there's no gap in frequency output, so I don't think any of the individual BA drivers are outright blown.

- Changed cables and music players. Same thing.

- When I see how Westone constructs their internals in the video below the drivers all appear to be wired in series, so one disconnect in a wire would render the entire monitor useless, which is not the case in my situation:



- I cleaned out the audio port and the metal screen at the end of the port with hydrogen peroxide. Doesn't change anything.

- Any idea what might be causing the entire left side to be lower in volume than the right? I'm wondering if the DragonFly Red DAC maybe sent too much voltage or current into that side and somehow damaged all the drivers in the same way?

Your tablet socket is probably shot ?

I updated my post. I changed music player devices and cables as well. The problem is within the left monitor itself.

Probably a lose wire, try wiggling the cables plug and see if it helps

I don't understand - how would a loose wire decrease the volume of all the drivers at once? A loose wire should cut out the sound completely. Check out the video I posted in the OP. All the drivers are wired in series. If there's a loose wire anywhere, the entire circuit would be broken and absolutely no sound at all should come out.

I'm a bit confused by the Westone video I posted above. Shouldn't there be a circuit board somewhere that contains the crossovers?

I'm no expert, but have you checked to see if there is a ton of ear wax or something else blocking the driver opening?

Yeah, I cleaned the ports out.
