Where it is shown on the picture below , the shaft got off its hole . I put glue in the hole then got the shaft back in place . Now I would like to know if this is a common issue with Grado Headphones and if you are aware of a better way to fix it .

Hello , Does a Digital Optical Cable mini to Toslink exist which does not use a Toslink to Optical Mini Adaptor, to connect a MacBook to a DAC (CIAUDIO VDA•2) ? Does the adaptor alter the signal ? Thank you ,
