My voice sounds like I have a bucket over my head!Updated a month ago

This is normally caused by one of two things.  
 
 You are plugged up because the dome is too large and it's not letting enough air into your ear.  Try various smaller domes with holes in them.  
 
 Secondly, there is too much base in the sound.   Use the app to reduce 500 Hz a little at a time and see if that helps.  If the domes that came with the hearing aids are all too big, call our customer service to get smaller domes.
