John, give Eddie Shoemaker (Btweengigs) a call. He had to deal with the same issues for years, and it cost him a small fortune in conventional hearing aids before resolving the problem. Back then, conventional hearing aids went for about $3,000 per ear. The Bose system cost me about $849 for both ears - big difference.
