Ultrasone PRO 2900 Balanced Headphones

New open-backed headphones with titanium-plated drivers, velvet ear pads and 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 and a balanced, double cable version of a pair of headphones. With the PRO 2900, Ultrasone has struck a balance between powerful and accurate sound production, with the airy and natural sound characteristics of an open-backed headphone.

Balanced versus Single Cable Headphones
While standard, single cable headphones are commonplace in most pro audio and 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 and voltage swing power, while reducing distortion components & eliminating crosstalk. The end result is decreased distortion and 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 and 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 and a diamond-cut logo insignia on the ear cup. The PRO 2900 features a 40mm titanium-plated driver and 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 and improved 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 and one straight) and spare speed-switch ear pads.
