The RS1i is the Masterpiece of the Grado collection, the ''Top Of The Range'' product which oozes class both in looks and sound.
So what does the i stand for in the new RS1i from Grado? Improved, that’s what!
Featuring a new species of handcrafted Mahogany earpieces made using an intricate curing process; Grado has been able to optimize the tonal quality. The RS1i uses new upgraded dynamic transducers and the new 8 conductor cable design all in an open-air configuration, the cups being open-backed. The result is a smooth, controlled and coherent sound with detailed dynamics.
Frequency response ranges from 12-30 kHz and the drivers are matched to 0.05dB.
Weighing 9oz, the headphones are an example of the wonder of Mother Nature with a gorgeous, dark-colored Mahogany look.

The History Behind Grado :
Grado, one of the oldest family owned companies in the Audio Industry, has for almost half a century been the leaders in design engineering for the high-end audio and recording industries.
Grado is famous for their remarkable headphone and phono cartridge designs and hold over 48 patents. Company founder, Joseph Grado is credited as the inventor of the stereo moving coil phono cartridge. He is responsible for more innovations in phono cartridge design than any other person in our lifetime and was inducted into the Audio Hall of Fame in 1982.
Time honored manufacturing know how and painstaking attention to design detail allows previously unobtained levels of pitch control, harmonic accuracy and bass quality to be achieved. All Grado headphones and cartridges are hand made to Grado's full performance specifications... nothing leaves the factory unless it sounds pure Grado.
All Grado headphones have a vented diaphragm design that incorporates a large air chamber. This design concept lowers the frequency resonance (distortion) of the diaphragm and extends bass response. The diaphragm is made of a low mass polymer, carefully formed to broaden resonant modes to reduce their amplitude. The diaphragm mass is determined with the compliance of the suspension in mind so that the desired low frequency resonance is achieved. The diaphragm's total mass is calculated to provide a full 20 KHZ bandwidth, while avoiding break-up at lower frequencies.
The Professional, Statement, Reference Series and along with the Prestige Series SR325is, SR225i and SR125i feature voice-coils that are wound from ultra-high purity, long crystal (UHPLC) oxygen free copper. The copper is slowly drawn through the die in extremely small increments and is annealed following each drawing operation. Ultra-high conductivity copper yields the clearest transmission and lowest coloration possible. The sound of UHPLC copper is smoother, cleaner and more dynamic. All use very high power neodymium magnets to provide maximum efficiency and better sound. Each headphone driver is made to Grado's high standards, then pair-matched for exact imaging. These headphones also utilize UHPLC copper in the connecting cable.
All metal work for the PS1000 and SR325is is machined from a special non-resonant, very hard alloy. Grado utilizes a special processing method to increase the material's porosity. This complex treatment insures that the earphone chamber has no "ringing" which might obscure detail or add coloration.
Grado's wooden Statement and Reference Series are hand-crafted at our labs from a new specially selected species of mahogany. An intricate procedure of curing is done between production steps to achieve optimal sonic quality. The overall sound remains pure Grado, warm harmonic color, full bodied vocals, excellent dynamics and an ultra smooth top end.
Technical refinements for Grado drivers include improved diaphragm and voice coil design for increased bass response and a larger perceived sound stage. A unique process to "de-stress" the diaphragm results in enhanced inner detail. An increased ability to control driver resonance virtually eliminates distortion. For all models, an improved headband spring will afford greater comfort for the majority of listeners.
AND THE SOUND?
Grado headphones can reproduce as natural a soundstage from stereo recordings and provide as much listening pleasure as a good pair of speakers do. Grado headphones are free of room effects and placement problems, and they minimize any interference from external noise. They also offer portability and the ability to listen without worrying about the neighbors. With Grado headphones, you will hear recordings with greater clarity and with deeper bass than others! Grado headphones are the antithesis of mass production, as each Grado headphone is hand-assembled and closely scrutinized to meet full performance specifications in the U.S.A.
