Does anyone sell pre fitted glasses frames with quality mics?
This sounds like something that would be really expensive - and for something that you can accomplish on your own for a tiny fraction of what your idea would cost. Just get some croakies and use them to mount your mics on your glasses.
Here are what mine look like. I slide the mics and croakies all the way up the temples to where they connect with the frames:
Even though I'm not particularly
about how I wear them, I have never been questioned, despite security approaching me four or five times over the years about my camera (I also shoot video).
Other things to to think about ... what would you do you if your prescription changes ... or something goes wrong with the mics ... ?
