Initially, compact earbuds, originally designed for hearing aids, gained widespread use alongside transistor radios. This culminated in the commercialization of the Regency TR-1 in 1954, marking a significant milestone in audio technology. The advent of the transistor radio revolutionized listening habits, enabling individuals to enjoy radio broadcasts anywhere. Since then, earphones have become a staple accessory bundled with personal music devices. In 1964, Sony introduced the EFM-117J transistor radio, which featured the widely adopted 3.5 mm connector. This innovation laid the groundwork for future developments, including its integration into the iconic Walkman portable tape player in 1979.
