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.
Professional engineers report that SR1a Earfield Monitors™ reveal more detail and accuracy than even their finest traditional studio monitors or headphones. 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.
Weighing in at only 425 grams (15 ounces). Unlike standard headphones who’s weight and heat create listener discomfort over time. The SR1a Earfield™ design eliminates heat buildup on the ears providing a cool, natural airflow. Your ears will also appreciate the complete absence of sound pressure against the eardrums caused by traditional sealed can designs. SR1a headphones can be worn comfortably for many hours at any listening level.
