The nickname "Hichiriki" is derived from the bamboo wind instrument that plays the lead melody in Gagaku, Japan's traditional court music. The instrument's powerful yet warm tone, characterized by the "Enbai" technique—where pitch is fluidly shifted through breath pressure—is often compared to the "voice of a person standing on the earth." The HS3000 embodies this pursuit of the "Sound of the Earth."

The Myrinx Composite Dynamic Driver has evolved into its second generation. This newly developed transducer utilizes a medical-grade polymer biomaterial "Myrinx diaphragm" combined with a Japanese-manufactured ultra-thin beryllium-coated dome. Manufactured through a precisely engineered functional coating processes, this driver delivers a lifelike, natural sound across the entire frequency range, capturing even the finest detail and nuance.

The HS3000 continues Acoustune's signature modular structure where the acoustic chamber and the mechanical housing are completely separated. Known as "Acoustune Capsule Technology (A.C.T)," this design allows users to safely swap acoustic chambers via a high-precision movable outer housing. With the HS3000, A.C.T is upgraded to Version 2.0, but is still 100% compatible with both the HS2000 and HS3000 series. The HS3000 comes equipped with the new "ACT08" chamber, featuring a beryllium-copper alloy body that focuses on a rich, thick midrange and a grand, transparent soundstage.

The HS3000 comes with the newly developed ARX600 cable, designed for optimal acoustic balance. It utilizes PCUHD® (Pure Copper Ultra High Drawability) from Furukawa Electric in a 4-core coaxial structure with a Japanese-made sheath in order to enhance noise resistance. It continues to use Pentaconn Ear IEM connectors by Nippon DICS for superior contact reliability. All metal parts are crafted from high-precision titanium for a luxurious texture. The ARX600 features a detachable plug system, allowing users to switch between the included 3.5mm and 4.4mm plugs.

The package includes the reference "AEX70" ear tips alongside the "AEX50," both made from "SMP iFit®" shape-memory polymer by SMP Technologies. 
•    AEX70: Based on the AEX07 shape but refined for material properties, providing a stable fit and lightweight comfort. 
•    AEX50: Features a unique double-wing shape for a wide contact area near the ear canal entrance, reducing pressure while creating a unique soundstage.
