Ultrasone PRO 2900 BALANCED Professional 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. PRO 2900 Technical Specifications S-Logic Natural Surround Sound Plus Dynamic principle, open Frequency range 6-42,
000 Hz Impedance 40 Ohm Sound pressure level 96 dB MU Metal buffer board, reduced field emissions in accordance with ULE (Ultra Low Emission) standard Driver 40 mm titanium-plated Weight 295 g (without cord) Included Accessories Carry Case, Hard Cable Type Symmetrical Impedance (ohm) 40 Frequency Response (Hz) 6-42000 Sound Pressure Level (dB) 96 Form Circumaural Ear Cup Closed back Driver Type Dynamic Driver Diameter (mm) 40 Top 10 Reasons to use Ultrasone 1. S-‐LogicTM Natural Surround Sound: The sound is moved out of the head in the room around you. The sound appears broad and detached. Directions and distances can be
heard and perceived – as if you’re in a live concert or in the sweet spot of fine monitor speakers. 2. Less hearing fatigue: Listening (or working) with headphones causes hearing fatigue rather quickly (ouch my ears hurt). With S-‐Logic the sound into your individual ear reduces hearing fatigue close to zero. 3. Hear more details: One of the most important facts for the working musician, engineer, or producer! You are able to hear more detail and nuances. For a consumer, you’ll discover hidden gems you never heard before. 4. Safer hearing: S-‐LogicTM reduces sound pressure levels (3-‐4 dB) up to 40% for the same perceived loudness. This may significantly reduce the risk of hearing damage -‐ a must if you spend a lot of time
in headphones. 5. Patented ULE Technology: Ultra Low Emission: Unlike other headphones, with ULE you have *radiation protection. Electro-‐magnetic emissions are cut to approximately 98%. Without ULE it’s as if you put 5 computer CRT monitors directly on your head. ULE is very important. 6. Design: Reviewers have spoken glowingly and use words like “upscale and elegant” and have written, “...the combination of high style and stellar sound are hard to beat.” All are incredibly comfortable and have a professional and cutting edge look. 7. Choice of materials: Edition headphones are made of the finest materials available. But all through the ULTRASONE brands, meticulous care is taken about the materials used. 8. Great Craftsmanship:
Great build quality, reasonable weight, precision-‐engineered and an incredibly low failure rate. 9. Warranty: 5-‐year transferrable limited warranty with receipt of purchase. ULTRASONE is that good. Need we say more? (2 Additional years on the Edition products with the mailing in of the warranty card) 10. Philosophy: No other brand concentrates on just headphones, has 60 patents worldwide, designs products with accuracy for the pro, consumer, and audiophile market. * not on the HFI 450 and the HFI 15G
