The ATH-R70x is Audio-Technica?s first pair of professional open-back reference headphones. Together with the ATH-M70x, they stand as a flagship model in A-T?s professional headphone lineup. Featuring specially designed drivers and acoustically transparent housings fashioned from aluminum honeycomb mesh, these headphones provide an accurate and natural open-back sound. They also incorporate a new, improved design of our popular 3D wing support system to provide even greater comfort during the prolonged use often required in professional settings. Robust yet lightweight, and equipped with a unique, dual-sided detachable cable that automatically maintains proper stereo orientation (no matter how it?s attached), the R70x headphones are built for lasting comfort, convenience and audio purity.
