"Well, that was either the most superlative laden, over the top, word salad of a review you've ever read or you're currently adding the SR1a to your online shopping cart. I understand if some readers think I was a bit too liberal in handing out accolades to the SR1a, but I have no problem standing behind every one of them. The RAAL-requisite SR1a is truly a game changer. There's no headphone like it available today, with respect to both design and sound quality."
"The SR1a is the only headphone to ever pull me away from my main two channel speaker based system. This doesn't mean I'm converting from my Wilson / Constellation system to headphones, because nothing could be further from the truth. There are many things headphones just can't do. There's no Johnny Cochran to get one around the laws of physics. However, the amount of time I now spend listening to my main system is substantially reduced because these headphones are so good."
"All music lovers, audiophiles, and even gear junkies need these headphones as part of their audio arsenal. It's just that simple. The RAAL-requisite SR1a are unequivocally the best headphones and the most notable audio product I've ever heard. Period. End of story."Read the entire review at: https://audiophilestyle.com/ca/reviews/review-raal-requisite-sr1a-earfield-headphone-monitor-r902/

"The Raal Requisite delivers a combination of bandwidth, resolution, speed and dynamics like no other headphone currently to market."
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.

Remarkable Sound & Remarkable Design.

Unparalleled musicality and detail… A completely adjustable soundstage, able to reproduce a near-field loudspeaker experience (not approximate or fake, but real, two channel imaging).

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