Introduction

Over many years, Sony has joined together with people who work in professional production studios,

and using their feedback has crafted superior headphones that meet their high expectations. One of the

most important elements among those expectations is accurate sound. In order to allow the wearer to

enjoy that sound in an outdoor environment, these headphones have passed through a development

stage that pursued perfection in functionality and performance. To provide accurate sound and a fit

designed for outdoor usage and portability without compromise, they are packed with technology that

Sony has accumulated to date as well as Sony’s own cutting edge technology. This pamphlet explains

these technological components.

1. For high sound quality

Rich bass and expansive treble:

Large caliber 16 mm diameter dynamic-type driver unit

In the closed-body-type in-ear headphones, a large caliber dynamic driver unit that is the largest in the

industry at 16 mm diameter was used. It enables a wide dynamic range available only with a dynamic

driver unit and playback of a broad range of sound, providing a clear and accurate sound with

incredible balance from the bass to treble range.

Suppressing unwanted vibrations and providing high resolution sound playback:

Liquid Crystal Polymer film diaphragm

For the driver unit diaphragm material, lightness and consideration to the seemingly contradictory

features of highly rigidity vs. high internal loss is essential. Though rigidity is key in accurately

converting input signals over a wide bandwidth into sound, a high level of internal loss is also required

to suppress unnecessary vibration of the diaphragm itself.

Liquid Crystal Polymer has already been identified for some time as a material that can provide a

balanced combination of these two characteristics in high order. However, previously it could not be

used to create diaphragms for headphones due to the inability of compositions and manufacturing

methods to obtain sufficient heat resistance and the inability to achieve the thinness required for usage

in headphones, caused by a low degree of film elongation and the difficulty of formation.

To solve this problem, a highly stretchable Liquid Crystal Polymer

was successfully developed for use as a casting film using polymer

varnish. This made it possible to enable both rigidity and a high level

of internal loss over a wide bandwidth, while also providing the level

of strength required to stand up to the process of creating a thin film.

In short, a material for creating the perfect diaphragm for

reproducing accurate sound was born.

Increasing flux density and achieving highly sensitive playback:

440kJ/m³ high power neodymium magnets

To enhance sound resolution, 440 kJ/m³ high power neodymium magnets which boast the highest

energy efficiency among general industrial goods were used. They supply clear mid and high tones and

powerful bass.

A manufacturing method called the “transverse field pressing method” boosts the magnetic force of

neodymium magnets even higher. This is a manufacturing method designed to strengthen magnetic

force even further by arranging the orientation of magnetic powder particles parallel in directionality

from the N pole to the S pole of the magnetic field that magnetizes the particles.

Enabling both high sound quality and miniaturization:

Driver unit-integrated housing

In order to miniaturize and thin the housing, a structure that integrates the driver unit and housing was

implemented. In addition to cutting unwanted air leakage generated from slight gaps between the

components, this also suppresses unwanted vibration and actualizes a smooth response at low pitch

frequencies.

Adjusting sound quality for each set by hand:

Sony original acoustic tuner

In addition to measuring each set meticulously during the manufacturing process, adjustment of

acoustic resistance material to constant values is also performed by hand. To achieve ideal

characteristics, only items that clear strict sound control requirements are shipped. Persistent detailed

tuning with precision controlled acoustic tuning components and original Sony acoustic tuners ensure

sound quality control at a level of precision higher than ever before.

Suppressing transmission loss of music signals:

High grade 7N-OFC Litz cord

The cord for transmitting the signal uses grade 7N OFC (Oxygen Free

Copper) of extremely high purity (99.99999 %). Suppressing signal loss in

the cord minimizes sound degradation.

The ultimate in sound insulation:

Noise isolation earbud

Pressure-relieving urethane foam inside the earbud equalizes pressure to the ear canal and

complements the complex bumps and dips of the inner-ear. Due to this, sound insulation is increased

with a fit that exceeds the comfort of previous earbuds.

2. For a snug fit

Actualizing a superior fit with a large caliber driver unit:

Closed-type vertical in-the-ear method

In using a 16 mm diameter large caliber driver unit, a closed-type vertical in-the-ear method wherein

the driver unit is positioned perpendicularly to the external ear canal was incorporated. And, in order

to absolutely minimize the thickness of the housing, which impacts the fit of the headphones, a high

strength magnesium alloy for the housing was used. This let us shave over 30% off the thickness

compared to housings that use common resin material.

Actualizing a highly stable fit for individual ear shapes:

Flexible ear hanger using TEKNOROTE™

For the hanger component, TEKNOROTE™, a plastic material that folds freely and

maintains its shape was used. Because this material can alter the hanger shape to fit

each individual ear, a superior fit stability is achieved. Also, TEKNOROTE™

provides a comfortable and safe fit because it is lighter and more difficult to snap.

Selectable by ear size:

7 hybrid silicone rubber earbuds

Newly developed, hybrid silicone rubber earbuds combine silicone of two different hardness levels.

This new design maintains the shape of the earbud tips where sound exits by making the core firm,

preventing sound quality deterioration via squeezing of the earbud tips. The outer portion is soft, and

this improves fitting to the outer ear canal. Overall, the earbuds have increased enclosure and provide a

more comfortable fit even during long usage periods. 7 earbuds are included to fit different ear types.
