Sony MDR-CD950

MDR-R10, also known as the king of headphones to SONY enthusiasts, debuts in 1988. And the economic downgraded version, MDR-CD3000, follows right after along with other introductory models. These are known as the first generation CD series.

Starting from CD1000, which has a pair of bio-cellulose drivers within, the introductory models of the first generation CD-series have very similar sound signature from one another. And CD950 is no exception. While its appearance is almost identical to CD1000(except with its ear cushion material), an amorphous diamond-absorpt diaphragm is implemented instead.

Unique Melody 3DD Part.1: Aesthetics

Introduction

From the China-based custom IEM manufacturer, comes great innovation; a triple-dynamic driver design, which is the very first in the industry. 

Unique Melody 3DD Part.2: General analysis

Continued from Part.1, Aesthetics.

Some people will call it an innovation, while the others say it is a crazy idea. A ⌀13 mm driver for the woofer, a ⌀8 mm driver for the mid-range unit, and a ⌀6 mm driver for the tweeter coupled into one IEM? That is 3DD, designed by Unique Melody, a well-known custom IEM manufacturer from the mainland China.

Oh, but they do not simply end there.. On the back of the woofer, there is an adjustable bass tuner made of a magnet, so that the damper, which is also magnetic, can stick on the woofer conveniently. As a result, the level of bass can be precisely tweakable, and the magnetic flux density of the woofer's magnet is effectively increased(thus its electroacoustic efficiency if the resulting B is any significant at all).

Driven with a pair of ⌀10 mm titanium-coated moving-coil drivers, t-JAYS is made for accurate sound reproduction and maximum comfort, according to the Swedish manufacturer.

And on top of that, in collaboration with Dirac, the company well-known for their custom sound optimization, JAYS come up with Curves specifically designed for t-JAYS models. While Dirac's DSP technology works most of the time, it may not do the job as well for some applications.
