Hi DIY-ers, I am going to give away an IEM, noting that this IEM may needs some sort of repair (imbalance frequency response) and I do not have the technique to fix it and wonder if any one here want to give a shot. The only request is please let me know the final result.

I don't want it but good luck with that, it's likely a dead BA or two on one side.
