Open-back acoustic structure that reproduces accurate spatial information imparted to the sound source

When reproducing a stereophonic sound source with headphones, a virtual stereophonic sound field is generated by performing signal processing on the information of the reflected sound generated in the space given to the sound source, taking into consideration the head-related transfer function. to reproduce.

By adopting an open-back acoustic structure that does not acoustically block the housing, the reflected sound inside the headphones is reduced, enabling more accurate sound field reproduction. In addition, for optimal control of the airflow in front and back of the driver unit, the acoustic resistor is used as large an area as possible to eliminate spatial resonance. Realizes natural and full bass reproduction with little coloring.

Reproduces accurate spatial information of the sound source

This is Sony's first monitor headphone that reduces reflected sound inside the housing with an open-back acoustic structure and accurately reproduces the spatial information of the sound source. Accurately reproduces the sound field intended by the creator. By optimizing the ventilation on the front and back of the driver unit, the reproduction in the low range is also enhanced.

5Hz-80,000Hz ultra-wideband reproduction brought about by a specially developed driver unit

[Diaphragm shape]

With an open-back acoustic structure, the sound quality of the driver unit itself is important. The diaphragm, which is the core of sound quality, needs to be both soft enough to reproduce low frequencies with sufficient volume and hard enough to retain its shape to reproduce super high frequencies without distortion. Through computer simulations and multiple trial productions, we have devised a special diaphragm shape that can achieve ultra-wideband reproduction.

[Duct structure]

The duct structure with a duct directly connected to the back of the driver unit optimizes the operation of the diaphragm. It improves low-frequency transient characteristics, which are difficult to adjust with an open-back acoustic structure, and achieves both low-frequency reproduction with sufficient volume and a sense of separation from the midrange, and accurately reproduces rhythms.

[Personal optimization for more faithful reproduction of spatial expression]

360 Reality Audio is a new musical experience that surrounds you with sound that spreads in all directions. With Sony's certified models that support personal optimization, you can enjoy a more realistic presence by optimizing the shape of your ears and the characteristics of the headphones with the "Headphones Connect" app.

Comfortable and stable wearability that enables long-term use

[Suede-like artificial leather]

The ear pads that come in contact with the ears for a long time are made of suede-like artificial leather that feels good on the skin, and the use of sufficiently thick, low-rebound urethane foam provides a comfortable fit. .

[Lightweight design]

At the site of music production, continuous use of headphones may exceed 6 hours. In order to reduce the burden caused by long hours of work, we have made every effort to reduce the weight of the headphones themselves. Taking advantage of the knowledge gained in the development of numerous headphones so far, we have reduced the weight in every detail.

User-friendly cable with detachable plug and replaceable ear pads

The cable is detachable for easy replacement, and has a fixed structure with a screw-type lock ring for secure connection. The ear pads can be replaced by the user. (*Replacement ear pads are available as service parts.)

φ6.3mm stereo standard plug headphone cable and φ6.3mm → φ3.5mm stereo mini plug adapter included

The cable plug uses a φ6.3mm stereo standard plug that is widely used in production sites. By using the included plug adapter, it is also possible to connect to a PC, smartphone, Walkman (R), etc. equipped with a φ3.5mm stereo mini jack. It can also be used for audition in a listener environment such as portable devices.
