Equipped with 5th Generation Sound Driver

The HS1750CU adopts a new manufacturing process and mechanical structure. Unlike the HS1600 series, it inherits the design of the flagship HS2000MX, achieving an overall quality upgrade through a more compact design. The sound driver has been improved from the 4th generation Myrinx to the 5th, with this generation enhancing resolution to create clearer and more detailed sound.

5th Generation Myrinx Driver The 'Myrinx Driver' is a dynamic driver made from Milinx, a medical-grade synthetic material, formed into a single-piece membrane for the driver's dome and edge parts. The Milinx diaphragm, while flexible, also possesses high rigidity, creating a hybrid-characteristic membrane.

From the first generation HS1001, second generation HS1500 series, to the third generation HS1600 series, this driver has undergone continuous design improvements. The 'HS1750CU' not only inherits the well-received sound of the HS1650CU but also incorporates fine-tuning.

Next-Generation Acoustune Design Identity

The 'HS1750CU' adopts the next-generation Acoustune design identity used from HS1300SS to HS2000MX SHO - Sho -. The shell shape, optimized in various dimensions and ergonomically improved, enhances fit while incorporating the metallic feel in a highly balanced design.

Modular Metal Body and Brass Chamber

The body shell uses a modular structure, completely separating the acoustic chamber (driver housing) from the structural shell (connector housing). This design reduces interference between acoustic and structural parts, suppressing sound quality degradation.

The 'HS1750CU' uses CNC high-precision cut brass for the acoustic chamber and aluminum for the structural shell, achieving high responsiveness while showcasing the deep bass performance characteristic of brass material.

For the chamber part, very thin metal processing was required to ensure acoustic space while pursuing sound quality improvement, but design improvements, including the addition of rib structures, were made to maintain strength.

New Reference Hybrid Cable 'ARC51' with 8-core Structure

The 'HS1750CU' continues to use the 'ARC51' hybrid cable, Acoustune's earphone standard adopted in the HS1600 series. This new hybrid cable aims to reduce conductor impedance while preventing audio signal transmission loss, improving S/N ratio across the full frequency range. It uses a hybrid of silver-plated OFC wires and ultra-fine OFC wires in an 8-core structure (triple-shielded/double-wound), with an outer layer of Japanese-made PVC selected by senior engineers for vibration reduction. This helps prevent external vibrations and suppress touch noise. Metal parts for the L-shaped plug, Y-splitter, and Pentaconn Ear connector are semi-matte black with a brushed finish for a premium look.

Pentaconn Ear Connector

Uses the new high-quality, high-reliability IEM connector 'Pentaconn Ear' designed and produced by Nippon Dics Corporation. Compared to traditional MMCX connectors, it offers tighter contact between plug and socket parts for superior conductivity. It also achieves both ease of connection/disconnection and durability.

Includes 'AEX07' Ear Tips and Carrying Case

As Acoustune's next-generation reference standard, all sizes (XS/S/M/L/XL) of 'AEX07' ear tips and foam-type 'AET02' ear tips are included. These ear tips prevent sound quality degradation and provide a high degree of fit. A carrying case for easy portability and protection of the earphone body is also included.
