Yeah, I'm pretty sure that's how they're supposed to be used.
Here is a real deal on Astromart!
"Unused Orion AudioView 7X17 Binoculars with AM/FM radio. Includes batteries, lens cloth, strap and case. $25 Shipped."
Has anybody EVER heard of a 7x17X? Batteries are included! I wonder what the optical quality is like. They would not work well for birding because the radio would scare all the birds away. I think somebody should buy these and review them. Here is the link and the picture.

You use the radio to listen to your remote radio mikes so you can locate the birds by song ...
