If you have a reason to follow someone around and eavesdrop in on their conversations — or heck, even if you don’t — what better way to say “privacy shrivacy” than with the Micro Agent Listener. This compact gadget has an 12-inch extendable microphone on one end so you can stand around one side of the corner while hearing all of the dirt that’s being said on the other side. Of course it comes with an earclip but you will still look like a dork if you wear it like that plus you will blow your cover at the same time.
The listener also has an automatic volume limiter that will stop the relay of louder noises, handy when you’re on surveillance on a construction site, by a busy freeway or when your about-to-be-ex-girlfriend catches you following her. It’s powered by one button battery which comes with the device when you pick it up for about $50.
