The Third Generation The Grado family makes exquisite headphones by hand in their Brooklyn facility. Each iteration of products represents a significant step forward in sonic reproduction. Grado's headphones have already been called "The finest electricity-to-sound transducer in the world". So how did they improve upon perfection? Every single component, surface, and material used in The e Series has been upgraded and optimized for one purpose - outstanding dynamics and fidelity.
Grado's proprietary SpaceBlack Polycarbonate is engineered to absorb excess energy and reduce secondary impulses, for a clearer tone.
The e Series method of curing select Mahogany tone-woods enhances their natural ability to reduce sound coloration and produce consistent results.
Rhodium, the most expensive precious metal on earth, is employed to prevent corrosion on connectors, and unwanted graininess in your music.
iMore than 60 years of Grado Labs expertise have led them to develop the most refined driver geometry in their history, which tracks music frequencies with unequaled precision.
Design refinements within the housing prevent stray resonance from interacting with the driver, thus protecting the purity of reproduction.
The magnetic field has been fine-tuned for symmetry throughout the full range of the voice coil.
Even the glue is new, optimized for greater strength, less mass, and better reliability.
The traditional Grado open-back form factor has not changed, because it delivers superior sonic quality and greater realism than closed-back.
So if you're looking for one good reason to invest in The e Series headphones here it is: they bring you closer to your favorite artists. Your listening experience will feel more intimate because nothing comes between your ears and the performance. SR325e: Less Bling, More Zing We chose a powder-coated aluminum housing for these headphones because the added mass means smoother transitions from the lowest frequency range to the highest. You might also enjoy the authentic 60‘s style, which goes perfectly with skinny ties and sullen glances. The genuine top-grain leather padded head-strap is Brylcreem resistant. The Top of the Range Prestige Series Headphone. The new SR325e has a new driver and cable design. The added mass from the metal housing minimizes transient distortions. With the new 8 conductor cable design you will notice superb control and stability of the upper and lower range of the frequency spectrum, with both supporting Grado's world renowned midrange. The SR325e will produce a sound that is pure Grado, with warm harmonic colors, rich full bodied vocals, excellent dynamics, and an ultra-smooth top end. General Design 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. 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. All metal work for the PS1000 and SR325 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. Sonic Reproduction 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. Grado Prestige Headphone Series Details The Professional, Statement, Reference Series and along with the Prestige Series SR325, SR225 and SR125 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. Comments on the Grado SR325 "This headphone has something magic: a rare musicality that preserves the natural elegance of the music. The medium is refreshing, natural and sensual. The richness of the harmonics in the medium pulls you in. The instruments have a credible texture. The spectral balance is good. The timbres are rich and at time exceptional. The definition is flawless; the music keeps its nuances and richness of expression." -Diapason magazine / France "…the degree of insight these headphones offer into sounds is really very impressive. This is high quality music reproduction, thoroughly deserving of serious attention." -Richard Black / Hi-FiChoice magazine "What you need is a serious set of cans to do justice to your music and what better way to enjoy pristine hi-fidelity than by using staunch traditionalist Grado’s note-perfect SR325 earmuffs" "I'd encourage anyone who wants to escape the typical, in yer face, cheap can sound to listen to these Grados." HiFi Choice, Winner of Audio Video's "GRAND PRIX AWARD" "Of all the Grado Prestige headphones I've heard, the SR325 is my favorite!" -Audio magazine / Vol. 82, No. 6 / John Gatski "The SR325s are easily the flattest, most accurate sounding phones tested, for critical monitoring, the Grados are hard to beat. Of all the phones tested, the SR325s were the only headphones I felt trustworthy enough for mixing." -Pro Audio Review / Vol. 4, No. 6 / Loren Alldrini Goodcans.com Review of the Grado SR325 Headphones
My wife bought these for me for Christmas, and they are becoming my favorite pair of listening headphones. You can hear every detail in the music with great clarity. I also have a pair of SONY MDS7506 Studio Headphones. While the Sony will put you onstage with the artist, the Grado's put you front and center in the audience for maximum enjoyment.

After weighing my options for quite some time (AKG k701/k702, db880, etc) I finally decided to grab a pair of these headphones. I could not be more satisfied with them. I don't find them too uncomfortable like all of the reviews I found on them claim, nor do I find them "too bright" as others claim. Crisp, punchy bass that isn't overdone, and these sound great plugged right into my ipod. Add some power and they are amazing! Best headphones in the price range easily.

These headphones have a clarity, purity, and accuracy of sound that is unmatched by any others that I've tried, and I have tried a lot. I hear everything, even the most subtle kiss on a cymbal that disappears on other items. After several frustrating and expensive disappointments, I was just stunned when I received these. I see no need to try any others.
