it seems the fit of my 8A is rather fine but because I chose the comfort instead of musician fit, I think it comes loose every few mins or with constant motion so I'm just wondering if I should send it back for a refitting or is there a way to improve on the fit of the canals such that it stays in place once its in?
Overall, there isn't anything obscenely wrong with the fit but my only issue here is the canal fit.
Maybe because I opened my mouth a little too wide for the impressions?
Not too sure but according to Wizard if I were to get musician's fit I have to get a new set of impressions which will mean extra costs and another month of long wait.
Will musician's fit hold it better in place?
