New open-backed headphones with titanium-plated drivers, velvet ear pads & Neutrik connectors feature an airy & transparent sound Ultrasone Inc. announced the only open-backed headphone in its legendary PRO Series, the PRO 2900. For the first time ever, Ultrasone is releasing both a standard, single cable version & a balanced, double cable version of a pair of headphones. With the PRO 2900, Ultrasone has struck a balance between powerful & accurate sound production, with the airy & natural sound characteristics of an open-backed headphone. Balanced versus Single Cable Headphones While standard, single cable headphones are commonplace in most pro audio & audiophile applications, a balanced headphone coupled with a balanced amplifier offers unique advantages over the former such as increased audio performance due to a doubling the slew rate & voltage swing power, while reducing distortion components & eliminating crosstalk. The end result is decreased distortion & ultimately superior audio performance. To achieve this paragon of headphone fidelity, balanced headphones must be paired with a balanced amplifier (4-channel amp with 2 inverted positive channels) that instead of using a common ground, uses two wires per side to deliver positive & negative audio signals to each side of the headphone. PRO 2900 Features Ultrasone's PRO 2900s boast a classic black design, velvet covered black ear pads & a diamond-cut logo insignia on the ear cup. The PRO 2900 features a 40mm titanium-plated driver & a soft USC-Cable that is paired with industry leading Neutrik connectors. Ultrasone's newest headphones contain MU-Metal shielding (ULE technology) that reduce the amount of radiation directed to the listener by up to 98%, as compared to conventional headphones. The PRO 2900s also contain Ultrasone's patented S-Logic Plus technology for reduced sound pressure on the ear drum & enhanced tonal perception. This gives users the advantage of wearing Ultrasone headphones for many hours without their ears hurting. Ultrasone's PRO 2900 comes in a hard-sided carrying case along with two removable cables (one spiral & one straight) & spare speed-switch ear pads.
