I wear one in each ear. No one notices unless I happen to adjust one of them for some reason.
Don’t cheat yourself. Get the aid. I didn’t get mine until 3 years ago, and I have missed out on decades of things.
This has been a helpful thread for me. Over the past few years I’ve noticed that I’ve had to have the TV louder than my Wife needs it. And I do miss snippets of conversation. I’m 47.
I have tinnitus. Pretty bad. I went to an ENT and an audiologist. Mild loss in on ear. Mild to moderate in the other.
At least I have a base line now, and I can watch it. I’ll probably get hearing aids within a year or two.
Closed Captioning is a lifesaver here. When captions aren’t available, I’ll wear wireless headphones when we watch TV. I’ve tried several kinds over the years, and none of them can hold a candle to the Sennheiser RS 140. It holds a charge, doesn’t need to be re-synced with the base if you look at it wrong, has volume controls on the headset, and the batteries are replaceable.
Being an electrical engineer, when getting my wife’s latest hearing aids I asked this very question 
It has to do with a combination of rapidly rolling technology improvements, and a relatively low unit quantity for the market. There just isn’t enough volume for economies-of-scale to offset the PD costs. I routinely make mundane electrical gizmos on the job that have unit costs of several thousand dollars, but are less complex than a $20 alarm clock.
Now wheelchairs, on the other hand? No freakin’ way they should be that expensive. But then, they’re billable insurance coverage, aren’t they
