USB stands for Universal Serial Bus, and it is a standard interface that is commonly used for connecting various peripherals to a computer, such as a headset, keyboard, mouse, printer, and so on. USB ports can be found on most laptops and desktop computers.
A headset typically consists of two components: headphones for listening to audio and a microphone for recording audio.

Once connected, the operating system will detect the device and install the necessary drivers to make it work.
eSATA (External Serial Advanced Technology Attachment) is a type of interface used for connecting external hard drives, but it cannot be used to connect a headset to a laptop.

RG-6 is a type of coaxial cable that is commonly used for cable TV and satellite TV installations. It is not used for connecting headsets to laptops.
