Category: Headphones

Type: Owner's manual

Sony MDR-Z1000 headphones are engineered to meet the high demands of professional audio production. They feature Liquid Crystal Polymer Film diaphragms for accurate sound reproduction, ultra-wideband HD driver units for extended frequency response, and high-grade 7N-OFC Litz cord for minimal signal loss. The noise isolation earpads and housing gasket effectively block out ambient noise, making them ideal for use in loud environments. With a lightweight magnesium alloy housing and detachable cords, the MDR-Z1000 headphones are comfortable to wear and versatile for various applications.

1. Introduction

This device is designed to fulfill the high demands of functionality and performance required in a real

professional production environment. In order to thoroughly reproduce accurate sound and to provide

the acoustic isolation necessary for professional studio usage and actualize these features at a high level of

balance, we have integrated a full range of technology developed by Sony over a long span of specialization

as well as newly-developed technology. This pamphlet explains these technological components.

2. Producing accurate sound

2-1 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.

2-2 Ultra wideband HD driver unit

This device uses a “HD (High

Definition) driver units” that is very

unique and can play sounds from a low

frequency to ultra high frequency with

only one unit. The diaphragm comprises

of the Liquid Crystal Polymer mentioned

earlier. The shape of the diaphragm

underwent hundreds of shape pattern

simulations and numerous listening

tests before it was finalized. Also, 360

kJ/m

high power neodymium magnets

are used, providing the source of

power needed to drive the diaphragm,

enabling reproduction of a wide range of

frequencies from 5 Hz to 80 kHz.

2-3 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.

3. Providing acoustic isolation

3-1 Noise isolation earpad

Since the earpad has a large impact on acoustic

isolation, a newly-developed noise isolation earpad has

been employed. After dozens of ergonomic tests and

inspections, the perfect shape was finalized. The oval

earpad shape effectively covers the entire length of the

ear, preventing the natural tendency to leak sound.

Reducing the width helped to reduce the problem of

hair getting in the way while also for achieving higher

acoustic isolation. Moreover, we use pressure-relieving

urethane foam for the cushion material for the earpad interior with improved suppleness towards the

natural shape of the ear area to further increase acoustic isolation.

3-2 Preventing unnecessary sound leaking with a housing

gasket

Inserting a gasket in the gap between the

baffle and the housing that covers it prevents

unnecessary sound leaking while simultaneously

improving acoustic isolation to cut sound leakage.

Our chief goal was a balance between sound

quality and acoustic isolation through other

means, such as like minimizing the necessary

housing openings.

4. Function and specification regarding professional

usage

4-1 Lightweight magnesium alloy housing

In professional studios, it is common for headphones to be put

to use for long periods of time. That is why comfort is extremely

important from the standpoint of reducing fatigue. And the

lightweight design plays a large role in providing that sort of

comfort.

The housing component forms the largest part of the headphones.

Here we used magnesium alloy, which is known for having a high

specific strength (strength to weight ratio) among usable metals at

industry level. This allowed us to make the housing thinner and

achieve a lightweight headphone body that is approximately

10 %*

lighter than before. Moreover, the magnesium housing

prevents unnecessary vibration for smooth bass response and

clear mid-high range sound.

4-2 OFC voice coil

For the voice coil, high grade OFC Litz cord is wrapped around the craft bobbins. This lightens the voice

coil weight for high sound quality while simultaneously improving durability and providing a power

handling capacity of 4,000 mW. This prevents problems such as damage caused by typically unexpected

large scale input events that occur frequently in professional studios.

4-3 Detachable cord

The cord is detachable, and we have included both a 3 m and 1.2 m cord. You can select the cord for the

situation, such as the 3 m cord for studio work where length is essential, or the 1.2 m cord for portable

operation, for example, combined with a camera-recorder for location work.
