Spy Wall Listening Device

Listing ID #3408769

Technically Speaking The Device Is Pretty Simple. It Works By Amplifying The Vibration Of Audio. Whenever You Talk, The Voices That Are Generated Are Wavebands, These Wavebands Travel Through Short And Long Distance. And When The Inspector Gadget Audio Device Is Switched On, It Picks Up These Wave Bands And Amplifies Them, So That You Can Listen To Them. All You Have To Do Is To Put The Spying Device Against The Wall, Connect The Earphones With It And Listen To Things Being Said On The Other Side Of The Wall.
