Bluetooth Headphones is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect two or more electronic devices like telephones, computers, tablets etc. without new wires but via Bluetooth connectivity which allows them to communicate with each other within close range through an exchange of data packets wirelessly transmitted by means of radio signals using adaptive frequency-hopping spread spectrum modulation technology which is robust against interference so that a connection can be
