For more information about this specific headphone look at: http://www.head-fi.org/t/650912/hifiman-he-6-re-400-iem-and-ultrasone-pro-900-in-depth-reviews I have bought this headphone from conquerer2 (see link) a few months ago. I have used it only once. My amplifier has not enough gain and not enough power to drive this headphone on demanding classical music material. I needed to try , to know for sure. Bought it for 900 dollar, sell it including all the extras for 800 dollar excl. shipping and paypal fees. There is one very small blemish on one of the cups. It is barely noticeable and too small to photograph. Prefer a European sale, but will ship to everywhere.
