True Ribbon SR1a.
The world's first Earfield headphone monitor.

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.

Even compared to headphones already well regarded for their ability to render micro-details, such as Focal’s Utopia, the STAX SR-009S or the LB-Acoustics MySphere, the SR1a are clearly superior.

The SR1A makes me not want to listen to any other headphones; or from someone I respect: “it’s what every headphone wishes it could be”.

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.

World class professional monitors I can take on the road! I can finally trust my sound everywhere.

SR1a Freedom.

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.

A radical departure from traditional headphone designs that presents speed, dynamics and imaging that exceeds flagship planar and electrostatic systems. Arguably the most exciting new development in headphone engineering in a long time.

Such a quickness to the sound, immediate stops and starts, tremendous dynamic swings with macro punch and fall back to micro detail. These are designed for mixing and mastering and would make great uber-phones for home use.

Not only the truest sound and bass picture of any headphones I’ve ever heard, it allows a vocalist to sing and hear their own natural voice in the room without bleed concerns due to the ribbon design.

Incredibly comfortable.

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.

I have been hesitant to make EQ choices on headphones in the past, but with the SR1a I feel confident to charge forward! These are the Ferrari of headphones!
