I've had my set of iBasso IT01's for years now and they're still going strong. But recently the small black rubber o-ring seal has broken on both of them. It sits at the tip of the driver underneath the silicon ear tip.
Whenever inserting into my ears the silicon just pushes back and I cant get a seal.
I haven't for the life of me been able to track down what this part is called or if it's even a common design choice.
Does anyone know what this part is called/what the measurements would be for a generic o-ring inner/outer diam?
