I am deaf in my AN ear and I have lost High frequency hearing in my right ear. Yes I have a hard time hearing all sylables of some words so at times i think I'm hearing a foreign language. I tried the aids that plugged my ear and couldn't adapt to them. Then i tried a Siemens Acuris. It fits behind my ear with a small clear tube that fits in my ear. I can't tell i have it on and folks can't see it either. It's adjusted according to a computer so that the frequencies I'm Deficient in come in louder than those I hear normaly. Liewise noises that are uncomfortable(loud) can be toned down a bit. And the best part is it has a pocket remote control that allows me to raise or lower the volume according to my situation i.e. louder in church, lower at home. Cost is about $2400 but worth it to me. Most audiologist will let you try one before purchasing and they don't need an ear mold made for fitting. They do need a very accurate audiogram to set the digital computer chip in the ear clip through a complex computer program. I love mine and a friend of mine got one for each of his ears and he and his WIFE have thanked me for the info more than once. I wish you well, Bob P.
