It all started with the Ultrasone Edition 7 and Ultrasone Edition 9 'uber high-end' headphones a few years back -- those hand-crafted designs have now evolved into the Ultrasone Signature PRO model. Offering a more 'dry' focus and a stringently clear but not overly analytical response versus the luxe richness of the current Ultrasone Edition 8, the Signature PRO presents an ideal sound for both music lovers and pro audio workers seeking tonal balance and faithfulness to the recording without marked colorations or frequency hump accentuations impacting the tone. The isolation delivered by the full-size Signature PRO circumaural earcups is not quite as thorough as the Edition 8 -- which remain the best-isolating headphones in the industry rating over -25dB in overall noise attenuation -- but the PRO will still manage to tamp down most intrusive air and road noise during your travels. As a nice plus, the ergonomic fit is not as tight as the Edition 8, so most listeners should find the Signature PRO more comfortable for the long haul. Also worthy of mention is the patented 'S-Logic' technology and the 'ULE' shielding developed by Ultrasone which is at the forefront of industry efforts to ensure safe long-term headphone use. 'ULE' engineering protects against electromagnetic radiation using magnetically absorptive 'MU metal' materials; the reduction in electrical radiation is something anyone who regularly wears headphones for hours every day may want to investigate. And although we've never been big fans of the S-Logic "surround sound" effect, it is fairly well-controlled and unobtrusive in the PRO's overall musical presentation. For the Signature PRO cosmetics, the exclusive (and extremely durable) elemental coatings of the Edition series are transmogrified to complement the PRO's meticulous sound reproduction and no question the PRO look is a bit more laid-back and unassuming compared to the flashy Edition 8 series. Ultrasone's leadership in 'monitoring-oriented' headphone development seems neatly realized in the Signature PRO, a true high-end sealed headphone fulfilling the critical audio desires of Ultrasone professional, portable, and home audiophile users.
Strictly hand-crafted exclusively in Germany and equipped with the most comprehensive, newest Ultrasone technologies, music fans and studio producers have long been wowed by the quality German-built engineering behind top-tier Ultrasone headphones. For the Signature PRO, the extravagant Edition-series cosmetics perhaps appeared a bit fancy for studio use. So they came up with an all-black Ultrasone Signature PRO look that combines top-of-category sound with a more subtle application of the high-quality materials used in the Edition line. The PRO features outer earcup plating incorporating finely polished, temper-toughened safety glass shells emphasizing its "clear" professional focus, and impossibly comfortable earpad & headband cushions that allow you to work and listen stress-free for very long periods of time -- significantly longer than with other cans of this type/size. Fine-grained goatskin leather is employed for all ear/headband pad cushions, and the material quality feels an obvious cut above the usual pads found on most other master-level headphones. From the outside, the Ultrasone Signature PRO may have something of a minimalist design aesthetic compared to their fancier brethren, but they revel in serious hard work or travel and are a pleasure to wear for all-day sessions. The dark grey ear/headband cushions are made of hand-softened leather from (sustainably-raised!) Ethiopian long-haired sheep and are fabric-sewn one at a time by hand in Germany. This rare genuine leather provides extra long-lasting cushion durability plus a comfortable fit along with outstanding 'passive' ambient noise seal and environmental isolation. As another cool feature, the Signature PRO comes with detaching cords and very durable 'B-lock'headphone cable connections.
