The Acoustune HS1750CU earphones offer the main ingredients of Acoustune high-end IEM’s at a more affordable price. The housing of the main unit adopts a modular structure that completely separates the acoustic chamber (where the driver is stored) and the mechanical housing.
Th Acoustune HS1750CU is the 4th generation Milinx driver adopted in the HS1600 series. It is equipped with a 5th generation Milinx driver”.
A next-generation design identity has also been adopted, and all aspects including acoustic characteristics, appearance, and fit have evolved.
Equipped with 5th generation Milinx driver
“Milinx Driver” is a dynamic driver made of Milinx, a medical synthetic base material, which is molded into a thin film with the dome and edge parts integrated. The Milinx diaphragm is a diaphragm with contradictory characteristics: it is highly flexible and yet highly rigid.
It is a traditional driver whose design has been continuously improved since the first model HS1001, second generation HS1500 series, and third generation HS1600 series, and the Acoustune HS1750CU has been fine-tuned while following the sound of the HS1650CU, which was popular in the market. Masu.
Adopting the next generation Acoustune design identity
The Acoustune HS1750CU adopts the design identity of the next generation Acoustune, which started with the HS1300SS and was also adopted in the HS2000MX SHO. We have improved fitting performance by optimizing each dimension and further improving the housing shape with ergonomics in mind, and have created a design with a shape that is easier to wear, a surface structure that emphasizes the feeling of a lump of metal, and a high balance.
Modular metal body & brass chamber
The main body housing has a modular structure that completely separates the acoustic chamber part (driver storage) and mechanism housing part (connector storage). Suppresses sound quality deterioration by reducing mutual interference between acoustic parts and mechanical parts.
The HS1750CU uses brass for the acoustic chamber and aluminum for the mechanism housing, both of which are cut with high precision by CNC.While maintaining high responsiveness, the deep sinking characteristic of the brass material is achieved. It achieves low frequency expression like this.
In particular, as we aimed to improve the sound quality of the chamber section, it was necessary to make it extremely thin in order to secure an acoustic space, but improvements were made such as adding a rib shape to maintain its strength, which also served as a design feature. I am.
New hybrid cable for reference with 8-core structure “ARC51”
The HS1750CU continues to use the hybrid cable ARC51, which is the standard for Acoustune earphones and was used in the HS1600 series. A new hybrid cable for reference that reduces conductor resistance, prevents audio signal transmission loss, and improves the S/N ratio across the entire frequency range. The cable, which has an 8-core configuration of a hybrid cable (triple shielded/double twisted) of silver-coated OFC wire and ultra-fine OFC wire, is a Japanese-made cable that was selected by engineers who have been involved in cables for many years for its vibration damping performance. Made of PVC. This prevents external vibrations and suppresses touch noise. The metal parts of the L-shaped plug part, Y-shaped splitter part, and Pentaconn Ear connector part are each semi-matte black and have a hairline finish, giving it a luxurious feel.
Adopts Pentaconn Ear connector
Adopts a new IEM connector “Pentaconn Ear” designed and produced by Nippon Dicks Co., Ltd. that boasts high sound quality and high reliability. Compared to traditional MMCX connectors, the plug and socket parts are in closer contact, providing superior conduction performance. It also achieves both ease of attachment and detachment and robustness.
“AEX07” that achieves high fitting and acoustics Earpiece and carrying case are included
A total of two types of earpieces are available at the same time, including all sizes (XS/S/M/L/XL) of the AEX07, which became Acoustune’s next-generation reference and was also used as a reference during earphone development, and the foam type AET02. Packing. Avoid deterioration of sound quality and get a good fit. Also included is a convenient carrying case that protects the earphones while making them easy to carry.
