ULTRASONE / ULTSIGMASTERMKII

Signature MASTER MkII is the latest professional use monitor headphone that incorporates user needs and updates Signature MASTER, which has been recognized by many sound professionals.

■Precision Sound Engineer's Delight
・""Signature MASTER MkII"" is the latest professional use monitor headphone with the slogan ""Precision Sound Engineer's Delight"" and has been updated to incorporate the needs of users by incorporating Signature MASTER, which has been recognized by many sound professionals, to be less tiring even after long hours of use, and to support balanced connections. Featuring the latest technology exclusive to ULTRASONE headphones, including innovative S-Logic 3, ULE, and FGC, Signature MASTER MkII delivers master-class reference sound that is high quality and perfect for studio mastering.

■Equipped with sealed dynamic 40mm titanium plated mylar driver
・Adopts a sealed dynamic 40mm titanium-plated mylar driver that is a direct descendant of the Edition series. The basic tuning follows the previous model's Signature MASTER. It ensures a wide playback frequency band, low distortion, high-speed, sharp response in all playback bands, and deep low-frequency playback that allows you to monitor even the sub-bass.

■Equipped with S-Logic 3 technology, a cutting-edge proprietary technology that realizes a natural sound field.
- ""3D sound localization"" that provides a more natural listening environment with headphones. ULTRASONE has undergone extensive research and development over the past 30 years to refine, tune and perfect every aspect and detail for natural surround sound reproduction. ULTRASONE's passion is to reproduce the minute nuances and recordings of sound and music using our unique S-Logic technology. The latest technology, S-Logic 3, is based on an innovative design that is reflected in natural spatial effects. It's a virtually inseparable listening experience from professional studio monitors, and unlike loudspeakers, it's not dependent on the acoustics of the room. ULTRASONE's proprietary S-Logic 3 technology creates a personal and portable listening environment similar to high-quality studio monitor speakers installed in an acoustically tuned studio space, recreating a natural sound field that reduces listening fatigue.

■DDF (Double Deflector Fin) technology
・DDF is a unique and cutting-edge technology that is part of S-Logic 3 technology. It is specially placed within the sound field to segment the intensity of sound events. As a result, the signal components in the directional mid-high range remain almost unchanged, while the low mid-low range is partially masked to become directional, and its planar exit distribution changes, further refining the S-Logic effect. This important feature allows you to get reference-style studio sound while improving the sense of openness. DDF creates a multi-layered stage for greater sound width, detail and depth. The image of the space appears naturally, with an excellent sense of separation and transparency. The center of the diaphragm is largely unaffected, but the associated low-frequency sound field has to flow around the DDF, causing changes. The result is a more linear sound sensation for the listener, enhanced signal perception, and significantly improved depth and distance perception, which is especially important for professional users. With this S-Logic 3 technology, ULTRASONE takes a big step towards perfect natural surround sound that creates a natural three-dimensional effect.

■Uses ULE technology, a unique technology that reduces electromagnetic waves generated by the driver.
・Uses ULTRASONE's proprietary ULE (Ultra Low Emission) technology that reduces electromagnetic waves generated from the driver and reaching the human body. While various research is being conducted around the world on how electromagnetic waves affect the human body, ULTRASONE's philosophy is that the health of users who wear headphones directly on their heads should be our top priority. ULE technology uses a special military metal called ""mu-metal"" developed to make submarines undetectable by detectors, and is installed between the source of electromagnetic waves and the human body.ULE technology is designed to bend the direction of electromagnetic waves before they reach the human body due to the material's properties that strongly induce electromagnetic waves, and as a result, shut out up to approximately 98% of electromagnetic waves.

■Uses a newly designed internal board and supports balanced connection for the first time in the series
・Signature MASTER MkII also focused on feedback from audio enthusiasts while incorporating user needs. By designing and adopting a new design for the headphone's internal board, it is the first in the Signature series to support 4-pole balanced connections. In addition to the previously included Neutrik 6.3mm standard plug 3m straight cable and Neutrik 3.5mm plug 1.5m straight cable, a new 4.4mm balanced plug 1.4m straight cable is now included. This allows users to further expand the possibilities of sound according to the purpose and connection destination.

■Features the latest FGC technology, mesh structure, and sheepskin leather for comfort even when used for long periods of time
・Signature MASTER MkII uses the latest FGC technology that creates a depression-like notch in the center of the head pad. FGC technology disperses pressure on the area where the head pad hits the top of your head, making it less tiring. In addition, a breathable mesh structure is used under the sheepskin leather head pad to prevent stuffiness caused by sweat. In addition, the superior fitting and sound-insulating sheepskin leather ear pads reduce the burden on your ears and head, allowing you to listen comfortably for hours on end. The design of the metal plate on the housing is also more stylish.

■Robust Signature carrying case included
・Comes with a semi-hard carrying case for the Signature series that protects the main unit and cables, and is convenient and robust to carry.
