Was browsing around and ran into these.
It reminds me of the old Bonephone from a decade or two ago that used simply a rectangular pad to transmit the sound to directly vibrate your inner earbone. Nobody could hear a thing except you.
The last Bonephone I saw on ebay fetched a very surprisingly large sum.
So as far as I can tell , nobody will hear a thing except you, in there is NO external noise at all, and at the same time I would imagine you can hear all around you also. That would be a strange experience, or maybe not
Seems like these are also waterproof
I assume there are also currently some bluetooth jobs using similar tech now. I wouldn't know I don't BT or use Phones much.
Anyhow check them out.
I tried cutting and pasting the tech specs but it got goofy, so hit the tiny tab and see for yourself.
Checked a few reviews and one that stood out was there was a person that had trouble hearing due to an accident, and these look like they bypassed that for them. Interesting anyhow.
I'm sure these have their place and time.
