RAAL Requisite SR-1b
RAAL Requisite SR-1b
What makes this headphone unique is not only the driver - a ribbon type - but also its open design: it does not have a round pad around the driver, it hangs freely next to your ear and can be angled closer or further away to impact stage presentation and how strong the treble is. The driver itself adds incredible speed and resolution, which makes this something you got to hear once in your life.
RAAL Requisite SR1b
Earfield™ true-ribbon headphone monitor with a speaker-like soundfield
Something truly unique.
RAAL Requisite approached a simple question in an uncompromising way: what does it take for a headphone to feel more like listening to speakers?
First, you decouple the sound from the ear—then you add a mechanism that lets you angle the drivers like speakers in a room. And because that still wouldn’t be unique enough, RAAL doesn’t rely on a dynamic driver or electrostatic tech. They use true ribbon drivers.
Ribbon drivers are incredibly fast, with transient behavior that’s hard to compare to anything else. RAAL explicitly talks about mixing and mastering because the SR1b can expose details that are invaluable in professional work.
What RAAL says
SR1 Earfield Monitors™
Professional engineers report that SR1 Earfield Monitors™ reveal more detail and accuracy than even their finest traditional studio monitors or headphones—helping achieve high-quality, transferable mix results in non-traditional environments. The accuracy, musicality and portability free the engineer to work whenever, and wherever they choose.
SR1b – Earfield™ soundfield
The SR1b 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.
True-ribbon bandwidth
The SR1b is also the world’s first True-Ribbon headphone. Specialized ribbon drivers reproduce 30 Hz to 30 kHz to eliminate the need for sealed chamber bass and enable open-air baffles (front and back) for a true full-frequency soundfield.
