Pinnacle PX with crosstalk

I’ve got a MEE audio Pinnacle PX IEMs since 2018, they did their job pretty well until now. Recently I noticed that it has a kind of cross talk. I can hear like 50%Right / 50%Left on one side and only 50%Right on the other or 50%Right / 50%Left - 50%Left if I change the earpieces.
I can’t really explain what is going on so I recorded it (with a poor quality, but it was the best I could do in stereo). I ran two tests in which I just changed the earpieces positions without changing the R/L cables position between them.
I don’t know what’s going on, at first I thought it was the cable, but after I’ve changed the earpieces I noticed that the problem transfers to the other side.

I’m looking for understanding what happened and if I should get a replacement part or just go for a new IEM.

Let me know if you need any further information.

It’s probably the wire is worn. If you can, try a different one.
