Open-back reference model for professional use For everyone involved with sound, and for those who are particular about sound. A flagship model that pursues accuracy, detail, and comfort. ■ Open-back reference model for professional use Unrestricted driver performance for natural and accurate audio production. The sound of open-back headphones is strongly influenced by the performance of the driver, and the movement of the diaphragm is directly converted into sound. This provides an extremely pure open-back sound with minimal distortion. ■ Equipped with a φ45mm large-aperture driver specially designed for the "R70x" series, which reproduces the entire frequency range with high purity By optimizing the acoustic circuit with headphone design and development and proprietary technology cultivated over 50 years, we have adopted a newly designed driver that accurately reproduces the entire frequency range. It enables realistic sound field expression and reproduces accurate and natural sound. ■ Headphones that pursue the limits of open-back design, controlling the flow of air and reproducing the original sound only with the movement of the diaphragm ■ Acoustic design for mixing and mastering ■ A tool that provides accurate and reliable reference ■ High-impedance specifications* assuming connection with professional/commercial equipment ■ Comfortable even during long work sessions thanks to the newly designed headband and head pads With a sturdy metal headband structure and new head pads, it combines simplicity and strength, providing a comfortable fit even during long hours of work. 【Keywords】 audio technica audio-technica audiotechnica audio technica audio-technica audio tech headphones headphone professional studio monitor headphones studio monitor headphones monitoring recording mix mixing mastering DAW DTM bayonet lock mechanism cord carrying pouch included open-back dedicated design driver honeycomb aluminum punching mesh audio production open-back sound reference headphones closed-back/semi-open headphones ATH-R70xa ATHR70xa
