PROline Series Headphones Launched at Winter NAMM

PROline 550

PROline 2500

Ultrasone of America unveiled their new PROline series. The new PROline 750, 2500, 550, and 650 headphones offer Ultrasone's patented S-Logic technology in a new, sleek design, with standard protection from EMF radiation up to 98%, detachable cables (coiled and straight), replacement pair of speed-switch ear pads, and easily replaceable drivers.

The PROline series was created for professional users with a higher degree of transparency and spatial sense due to the higher degree of ear anatomy involved. Each headphone is built with Ultrasone's S-Logic technology that utilizes decentralized transducer positioning to reflect sound off the listeners's pinna, or outer ear, creating a natural three-dimensional sensation without the use of processing. S-Logic produces a stereophonic surround sound field that is perceived to be broad, detached, and located in front of the listener, according to the company. S-Logic also reduces the risk of hearing damage by 40% as the headphone's transducers are not aimed directly at the auditory canal. Listeners perceive the same volume with sound levels at the eardrum reduced up to 40%.
