Hi,
I'm looking for a rather specific piece of audio hardware. I need "headphones" that let you perceive the entirety of noise produced by your surrounding and that don't touch your ears, at all.
So why not simply use speakers? Well, because they are too loud, I need something that can't be heard by other people around me.
The solution might potentially be a pair of aftershokz bone conduction headphones, but I heard they emit too much sound to your surrounding.
Any ideas?
