The World’s First Earfield Headphone Monitor.

Earfield™ technology delivers unheard of program accuracy and a speaker-like soundfield experience.

True Ribbons
For a Reason.

The SR1a is also, 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.
