for those that have the MRIE receivers… look at both of your receiver ends where the mic is located and see if you have a little white filter over the mic… I noticed the other day that the filter on my left receiver wire had come off and it is now just a tiny black hole… My audi called Resound today and they verified that the white filter was to keep out debris… my audi asked for replacement filters and he was given a rediculous price of around $200 for 50 of the little filters
