Credo of sound - The black PRO 2900i combines all the latest Ultrasone technology to form an extravagant pair of open headphones.
The PRO 2900i headphones are the first open PRO headphones from Ultrasone to feature the S-Logic® Plus technology. With the titanium-coated sound transducers, these open headphones have exceptionally fine and precise sound properties. If you are looking for a professional set of open headphones, the PRO 2900i will blow you away with the airiest sound reproduction thanks to its open system.
The accessories include the supplied PRO box, a 1.5m straight USC (ultra soft cable) with a 3.5mm stereo jack, a 3m coildes cable with a 6.3mm NEUTRIK stereo jack and a second pair of ear pads.
S-Logic® Plus is the cutting-edge advancement in the S-Logic® Natural Surround System, squeezing the BIG S-Logic® soundstage found in our PRO, Performance, Edition, HFI and DJ headphone models. S-Logic® Plus profits directly from innovations developed for our flagship Edition range, the ultimate headphones for critical listening.
This sophisticated new technology combines precision dampening with micro-acoustic reinforcement, allowing driver, buffer-board, and spatial parameters to complement one another in an optimal manner. So the acoustically redesigned ear-cups of these new models and their tonal fine-tuning result in a most neutral sound impression with more vivid perception of voices and instruments.
How does S-Logic® Natural Surround Sound work?
S-Logic® sends music around your head not just into it, because this technology uses decentralized driver positioning. Did you know that you use and need the outer ear for your three-dimensional understanding to define the direction and distance where a sound comes from? Instead of hitting the inner ear directly, with S-Logic® the signals are reflected off the surface of the outer ear in different directions before entering the auditory canal to create a natural three-dimensional Sound. S-Logic® is the only headphone system which includes your entire sense of hearing. S-Logic® does not change your personal hearing, it intensifies it for your individual needs and listening pleasure. S-Logic® does neither need artificial echo nor digital sound processing or cross over run time delay. You can hear the sound just the way the sound engineer has mastered it. S-Logic® does not only create a Natural Surround Sound sensation. S-Logic® allows at the same time a reduction of sound pressure levels at the eardrum by up to 40% (3 - 4 dB). This may reduce the risk of hearing damage while ensuring hours of fatigue-free listening.
