EcoTune Never try to fix the hearing apparatus by yourself if there is a problem with it. Never try taking it apart, possibly, as that will void any warranty that you may have. Take it somewhere that there is a professional that is qualified to fix it once they have evaluated it. https://groups.google.com/g/ecotune-price/c/1r3PXwZnvyo...
