HS1750CU

The HS1750CU is equipped with the fourth generation Mylinx driver adopted in the HS1600 series.
This model has been refined by utilizing the technology and knowledge gained from the development of the HS1300SS and HS2000MX SHO.
Equipped with the "5th generation Mirrox driver".
It also adopts a next-generation design identity, and has evolved in every aspect, including acoustic characteristics, appearance, and fit.

Equipped with 5th generation Mirrox driver

The "Mirinx Driver" is a dynamic driver in which the dome and edges are molded into a thin film of Mirinx, a synthetic base material for medical use. The Mirinx diaphragm is a diaphragm that has the contradictory properties of being highly rigid while being highly flexible. 

This is a traditional driver whose design has continued to improve from the first model HS1001, the second-generation HS1500 series, and the third-generation HS1600 series, and the HS1750CU has been fine-tuned while retaining the sound of the HS1650CU, which was well received in the market. 

Adopts next-generation Acoustune design identity

The HS1750CU adopts the next-generation Acoustune design identity that began with the HS1300SS and was also adopted in the HS2000MX SHO. The fitting performance has been improved by optimizing each dimension and further improving the housing shape with ergonomics in mind, and the more comfortable shape has been incorporated into the design with a highly balanced surface structure that emphasizes the metallic mass. 

Modular metal body and brass chamber

The housing of the main body adopts a modular structure that completely separates the acoustic chamber section (which houses the driver) and the mechanical housing section (which houses the connector). This reduces mutual interference between the acoustic and mechanical sections, thereby suppressing deterioration of sound quality. 

The HS1750CU uses brass for the acoustic chamber and aluminum for the mechanism housing, both of which are machined with high precision by CNC, providing high responsiveness while achieving the deep, penetrating bass characteristic of brass. 

In particular, with the aim of improving sound quality, the chamber needed to be made very thin and made of metal to ensure sufficient acoustic space, but improvements have been made to maintain its strength, such as adding ribs for added design value. 

New 8-core hybrid cable for reference use "ARC51"

The HS1750CU continues to use the hybrid cable "ARC51", which is the standard for Acoustune earphones, which was adopted in the HS1600 series. This is a new hybrid cable for reference that prevents audio signal transmission loss while suppressing conductor resistance and improves the S/N ratio across the entire frequency range. The cable is made of 8 cores of silver-coated OFC wire and ultra-thin OFC wire hybrid cable (triple shielded/double twisted), and the coating is made of Japanese-made PVC selected by an engineer who has been involved in cables for many years for its vibration-damping performance. This prevents external vibrations and suppresses touch noise. The metal parts of the L-shaped plug, Y-shaped splitter, and Pentaconn Ear connector are semi-matte black and have a hairline finish to create a luxurious look.

Uses Pentaconn Ear connector

Adopted "Pentaconn Ear" connector, a new IEM connector with high sound quality and high reliability designed and manufactured by Nippon Dicks Co., Ltd. Compared to conventional MMCX connectors, the plug and socket parts are in closer contact with each other, resulting in excellent conductivity. It also achieves both ease of attachment and detachment and robustness.

"AEX07" provides excellent fitting and acoustic quality. Comes with ear pieces and a carrying case.

The set includes two types of earpieces, including the "AEX07" in all sizes (XS/S/M/L/XL), which is Acoustune's next-generation reference and was also used as a reference when developing earphones, and the foam-type "AET02". This prevents deterioration of sound quality and provides a high level of fit. It also comes with a convenient carrying case that protects the earphones while making them easy to carry around.
