Loose band in audio jack

Hi!

Thank you for looking into this!

Alright, the case: RHA 10ti is the earbuds I use and I paid a nice sum for them to treat myself after finishing high school. Four months later I messed up.

Short story shorter, the plastic band between Mic and Ground is "loose". With that I mean that the top metal band is solid with the plastic, but the next metal band is moveable (the following bands are still as they should be). This means that there can be a gap between the top part (plastic to metal) of the plastic to the following metal band.

This of course results in music being played far and near (sound seems like it´s far away, vs. near being normal), and being played on different ears.

My thought is to use glue (I don´t care about the mic, but fear for the ground) as I can´t fit even a razor blade in the gap... Because if I can make it unmovable again it should theoretically by fine. Tape of course does not work, but I´m thinking either glue or melting plastic (thinking one of these: PP, PE-HD or PE-LD).

Let me hear some suggestions or tips.

Thanks a lot :)
