Our Take
OK, bud. We got something unique here. An actual true leap of innovation. The SR1a is like nothing else you've ever seen or heard. If you live in the Philly/NJ/DE area...you NEED to schedule an audition with us. Words cannot do it justice. Pair the SR1a with your fave speaker amp (100W+ loudspeaker amp required) and get ready for nirvana.

Watch our owner share his impressions:

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.

Watch as headphone enthusiasts experience the SR1a for the first time at CanJam SoCal: 

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.

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.
