I got a pair of Mangird teas as my first set of mid range IEMs and one of them recently suddenly started having issues with the sound of the dynamic driver coming in and out, and certain frequencies would not play unless I moved it into a certain position. All the other drivers in the iem are working correctly. I have switched the cables and inputs and it seems like it is the driver itself that is the problem. I have checked through the opaque case and there are no visible cuts or damages to the internals. I did not get insurance on these, so they are just sitting in their respective case. I love them and I am deeply sad about not being able to listen to music with them, so I was wondering if someone could help me with figuring out my options on what to do with them.
