I've been wearing them for 10 years and have never had any bad comments as a result. When I first got them, work colleagues were visibly pleased for me that I had done something about a problem that was getting worse (not being able to follow quiet conversations in meetings).

The one time someone did say something slightly negative that included "oh it's that guy with the hearing aids" I came back with "yes, and thanks to them I can hear what you just said, the clue is in the name", which got a general laugh that helped a lot. But that was a one off, apart from people slightly staring sometimes when they notice them, no one seems bothered.
