@itsmeagain ... Williamssound is the company my large church put in their amplifier system for us hearing impaired and I could hear every word before I only heard 1 in 10 words, hearing aids did not work we tried my hearing doctor and I, so I checked to see if Williamssound carried a personal amplifier they do. The ear bud amplifier I read cannot handle up to severe hearing loss I am med to severe loss. Good luck ...🙏🕊️
