1. What are headphones and how do they work?Headphones are tiny speakers that fit on your ears. They turn electrical music signals into sound waves that you can hear.

Electroacoustic Transducer: A device that converts electrical energy into acoustic energy (sound) and vice versa, fundamental to headphone operation.
Circumaural Design: Headphone architecture where earcups completely enclose the ear, typically offering superior noise isolation and soundstage.
Bone Conduction Technology: A method of sound transmission that bypasses the eardrum, sending vibrations through the skull to the inner ear, leaving ear canals open.
