This hybrid design has an inner sleeve of hand-crafted mahogany made by using the new series ‘e’ curing process. Its outer housing, machined from aluminum then chrome-plated, utilizes a special processing and casting method to increase the porosity of the alloy. This combination of wood and metal insures that the earphone chamber has no ‘ringing’ which might obscure detail or add coloration. The way the wood and metal housing moves air and reacts to sound vibrations is virtually unaffected by transient distortions. Grado has also designed the cable for the PS1000e; the twelve-conductor cable design uses UHPLC (Ultra-High Purity, Long Crystal) copper, improves control and stability of the total range of the frequency spectrum. The PS1000e also has a new 50mm driver and a newly re-configured voice coil and diaphragm design, resulting in unsurpassed speed and accuracy responses.
The cushion design creates the correct balance between the driver and housing to support the desired musicality. The cushion design also makes the PS1000e one of the most comfortable headphones in the world. Grado has taken all of our knowledge and over 60 years of experience in controlling resonances and eliminating distortions, and put them into our finest headphone ever, the PS1000e. Grado is unbelievably proud of this flagship product – listen and enjoy.

The Grado PS1000 buck a few trends of standard headphone design. The leather clad headband is rather thin and weedy looking, while two delicate looking steel rods are all that hold the earpieces in place. The earpieces themselves and their foam surrounds are also enormous. What’s more there are no extras like removable cables or remote controls here – these are pure listening tools. With regards the latter, the cable is very thick and feels high quality, and should the worst happen, re-cabling is possible but it’s not the simple plug ‘n’ play operation that it is with the Sennheiser HD800.
