What do spyware listening devices look like?

Spyware listening devices can vary widely in appearance, as they are often designed to be discreet and blend in with everyday objects. Common forms include small microphones disguised as household items like smoke detectors, alarm clocks, or USB chargers. Some may be as tiny as a pinhead and can be hidden in furniture or electronic devices. Others may resemble standard tech gadgets, making them difficult to detect without close inspection.
