[size=12pt]Dear Head-Fiers,[/size]
[size=12pt]A friend of mine needs a hearing aid. He got problems with it. The audiologist first tried an Universal IEM, later on a Custom IEM. [size=12pt]In both cases he (the audiologist) drilled a second hole through the tip to avoid air pressure in the ear canal. [/size] I have never heard of a second hole in the tip of an IEM. Could somebody give me an explanation?[/size]
[size=12pt]With kind regards, Artmon [/size]
