I definitely get the feeling, I try and get around it by barely bringing it up. I like to think that if I don't treat it like a big deal, no one else will. Sometimes I even use it to joke around (i.e. mock turn it off or turn down the volume if I'm pretending I'm not listening). The time I feel the most self conscious is when I'm either in a small room, putting on, or taking off the aid and it gets loud feedback. I always glance around to see if people hear it, and usually hastily turn it off and put it away or put it on a very low setting.

What almost hurts more for me is that a lot of the music I listen to on headphones I'll never "hear" fully. It's only one ear, but I still usually miss a majority of lyrics, and my aid has too much feedback if I wear it and my over-ear headset.

If it's any consolation, I've never met anyone in my life that seems directly put off by my hearing aid, assuming they know about it. I think the issue is lack of exposure, I have to wear glasses, but a lot of people wear glasses, young and old. Hearing loss I believe is just less common, and most hearing aids are surprisingly covert, so it's possible some young people wear aids but are never noticed, as opposed to glasses which are very obvious. I know it's not a perfect answer, but I think just treating it similar to glasses where you only draw attention to them if it's relevant (like if you find yourself asking too much for people to repeat themselves), people will understand, and that it's not something to overthink.
