I did some searching for pocket amps, and found a number of small headphone amps. It seems to me if I could plug a small mic into it, and ear buds for the output, that should be enough. Now I need to find those components, and put together some kind of system. My hearing loss isn't that bad yet. It mostly bothers me in a choral setting because I can't hear my own voice unless I sing very loud (not always appropriate in church!) I've had a chronic condition that seems to combine the hearing loss with episodes of sinus issues and vertigo. When the sinuses and vertigo are at their worst, so is my hearing. The doctor hasn't had anything useful to say, other than they ruled out any scary problems. Sort of a 'live with it' response. I can hear the singers around me better than myself, and they aren't always right. In the old days, I could power through since I have (or had) good pitch and sight reading skills. Now I can't win the fight since I'm unsure of my own voice. Oddly enough, I can hear just fine singing by myself, but I have a voice that sounds like a toad that gargled with Drano! Semi-related- If I do rig up something with a pocket amp, I wonder if I can run my horn mic through it so I can hear what I'm playing. I play alto horn in a re-enactment band, and it is rather soft, so they same problem exists of having a hard time hearing what I'm playing.
