I have hearing loss, especially in high-frequencies, and have worn behind-the-ear hearing aids for the past 20 years or so; also hissy tinnitus. Currently I'm using Oticon hearing aids, but any good manufacturer should have something that would meet your needs. My problem is I can't use those when listening on headphones - the mic is in the wrong place - so I have to take them off them. I'm looking into an ear canal 'hearing amp' where the mic would be by the ear opening. If I don't have a feedback problem, that should be a big improvement....
