With mine turned up all the way, I can hear voices well, a plastic bag very good.
But when you turn something loud on like a blender, the thing makes them louder...copied from first page
Sounds like they workwell. sounds get LOUDER.
What happens when there is a loud bang (gunfire). Everything should shut down for a couple secs.
Changing batteries shouldnt make the shutdown (noise blocking) any better. That should work without batts.
