Though it is a covert spyware, secret listening devices are actually used for ordinary, everyday issues. Some hidden listening devices are used at home to keep an eye on babies or nannies, or to listen to meetings if one is unable to attend and also to check up in the work place if the consumer is away.

Some devices are so small and require no source of power. These are impossible to find because they are not only tiny, but designed to last for a long time – sometimes for up to five years – without a concrete power source.
The sound clarity depends upon the make, but most of the devices can give a clear and static free audio.
The devices that cannot be detected are used on high levels, for example in the U.N meeting of huge companies where espionage is a common occurrence.
Although police and government agents are the most common of the consumers, the rest of the buyers are made up of businessman and companies that seek to keep their employees in check or search out those that are causing harm to their business.

In other more serious cases, these devices are used at high posts in the government, federal level or even in military operations. Hence, these devices prove to be extremely indispensible for a variety of people belonging to diverse fields.
