What kind of microphones do spies use for conversations?

Spies and intelligence operatives may use a variety of specialized microphones for covert conversations, depending on the specific needs of the mission. Some common types include:

**Lavalier Microphones**: These small, clip-on mics can be easily hidden on clothing and are popular for covert audio capture.

**Parabolic Microphones**: These are used for long-distance audio capture. The design focuses sound waves onto a receiver, allowing operatives to pick up conversations from a distance.

**Contact Microphones**: Also known as vibration microphones, these can be placed on surfaces such as walls or windows to capture audio vibrations.

**Wireless Microphones**: Many modern spy operations utilize wireless technology to transmit audio without physical connections, making them easier to conceal.

**Directional Microphones**: These mics are designed to focus on sound coming from a specific direction, helping to isolate conversations from background noise.

**Miniature Boom Microphones**: These can be used in surveillance setups where sound needs to be captured discreetly without being highly visible.

**Smartphone Apps**: Some spies may also use available technology, such as smartphone apps with advanced microphone capabilities, for spontaneous recording of conversations.

Each device may be chosen based on the environment, the level of discretion required, and the specific goals of the surveillance operation.
