The HS1750CU is a beautiful all rounder from Acoustune. A machined brass chamber body houses the 5th Generation Myrinx Driver from Acoustune, which delivers a rich, balanced sound that impresses with smooth yet vibrant vocals. The matte black anodised earpiece housing completes the package with an attractive, mechanical look.

The HS1750CU is equipped with a fifth-generation Myrinx driver, which is a refined version of the fourth-generation Myrinx driver used in the HS1600 series, utilising technology and knowledge gained from the development of the HS1300SS and HS2000MX SHO.

A unique material used in Acoustune driver designs, Myrinx is a synthetic base material used for artificial skin and surgical sutures, but it is also a high-performance resin that boasts extremely high acoustic performance as a dynamic driver diaphragm material.

In addition, the modular metal body structure of the HS1750CU completely separates the acoustic chamber (housing the driver) from the mechanical housing (housing the connectors), reducing mutual interference between the acoustic and mechanical parts and thereby suppressing sound quality degradation, a structure also adopted in the flagship HS2000MX SHO. The next-generation design identity from HS1300SS onwards has also been adopted, resulting in a product that has evolved in every aspect, including acoustic characteristics, appearance and fit.

The HS1750CU comes with the ARC51 hybrid cable, which was used in the HS1600 series and has become the standard for Acoustune earphones. This new reference grade hybrid cable for prevents audio signal transmission loss while keeping conductor resistance low, and improves the signal-to-noise ratio across the entire frequency range. The cable consists of eight cores of a hybrid cable (triple-shielded/double-twisted) of silver-coated OFC wire and ultra-fine OFC wire, and uses Japanese-made PVC selected for its vibration-damping performance by engineers with multiple years of experience in cable design. The metal parts of the L-shaped plug, Y-splitter and Pentaconn Ear connector are all semi-gloss black with a hairline finish for a premium feel.

The HS1750CU package includes a total of two types of earpieces: all sizes (XS/S/N/L/XL/XL) of the AEX07, which is Acoustune's next-generation reference and was used as a reference during earphone development, and the foam type AET02. They avoid sound quality degradation and provide a secure fit. Also included is a convenient carrying case that protects the earphones and makes them easy to carry.
