From RAAL-requisite

The SR1a by RAAL-requisite is the world's first Earfield™ headphone monitor. Experience mixing, mastering, and home listening with unparalleled accuracy and realism in a soundfield devoid of room acoustics and comb-filtering caused by work surface reflections. Earfield™ technology delivers unheard of program accuracy and a speaker-like soundfield experience.

Ribbons for a Reason

The SR1a is the world’s first True-Ribbon™ headphone. Highly specialized ribbon drivers were developed that reproduce 30Hz to 30kHz bandwidth in order to eliminate the need for sealed chambered bass and allow for open air baffles (both front and back) for a true full-frequency soundfield.

Helping to achieve high-quality, transferable mix results in non-traditional environments. The accuracy, musicality and portability of the SR1a frees the engineer to work whenever, and wherever they choose.
