The RAAL-requisite CA-1a and CS-1a aren't your typical high-end headphones - underneath those ergonomic ear cups are revolutionary Ribbon Drivers designed to deliver a level of resolution and detail that will give traditional driver headphones a run for their money.
The CA-1a/CS-1a features a simple transducer design but produces sound that's truly out of this world.
Its true Ribbon Driver design consists of a single piece of aluminum (per side) acting as a voice coil, suspension, and diaphragm - all in one. The ultra-lightweight piece of aluminum moves at an incredibly high speed, giving the CA-1a/CS-1a the ability to extract every detail from your favorite music with amazing clarity and accuracy.
The RAAL-requisite SR-1 was the first to feature RAAL-requisite's True Earfield Ribbon Driver technology in an open-ear headband design. With the right adjustments, the SR-1 offered good comfort and fit, but let's face it - nothing beats the comfort of a Circum-Aural design like the one found in the CA-1a/CS-1a.
Don't be fooled into thinking the CA-1a/CS-1a are the SR-1s in a Circum-Aural design - RAAL-requisite developed a new motor through years of R&D to ensure the CA-1a/CS-1a delivers the insane resolution, detail, and accuracy you've come to expect from a Ribbon Driver headphone.
The RAAL-requisite CA-series headphones are available in two variants: CA-1a and CS-1a.
The CA-1a and CS-1a are identical headphones with their main differences being ear cup aesthetics. The CA-1a features a standard gunmetal finish, while the CS-1a comes in four unique ear cup designs: Sticker Bomb, Green Camouflage, Red Camouflage, and Blue Shard.
CA-1a/CS-1a comes in three unique package options: Naked, Package, and ProPac.
Naked is intended for customers who already own a CA-1a/CS-1a. Naked comes with no interface, cable, or OB Barrels.
Package includes the CA-1a/CS-1a, accessories, TI-1b Transformer Interface, SC2 Cable, ITI-XLR Cable, and Open Baffle Compensation Barrels.
ProPac features everything in the Package option and adds a foam-lined, waterproof Flight Case for unbeatable protection when traveling with your CA-1a/CS-1a.
