Founded in 1962, Audio-Technica initially focused on the research and development of phonographs, and today mainly produces high-performance headphones, microphones and other electronic products. Audio-Technica products have excellent performance in large-scale concerts, professional broadcasting, recording studios, government agencies, etc.: the U.S. House of Representatives and Senate have chosen Audio-Technica microphones as essential government facilities, and Audio-Technica equipment has been used in the "Grammy" and "Rock and Roll Hall of Fame Awards Ceremony". In terms of headphones, Audio-Technica is characterized by a very good resolution of midrange frequencies, that is, the vocal part of the music is outstanding. At the price of 100 yuan, the in-ear can choose C770, which has good sound quality and comfort. If you like the head-mounted style, you can choose the S300, the price is 258 yuan. I prefer pop music, IM50 or IM70 are recommended, and the price is around 500 yuan.
