HarmonicDyne x Z Reviews Eris

HarmonicDyne x Z Reviews

The Eris was born a collaborative project from HarmonicDyne & long time audio reviewer Zeos from Z Reviews. This Headphones uses a bespoke 50mm dynamic driver developed by HarmonicDyne and physically tuned by Zeos for this project. The aim of the Eris is to be an experience unlike any other currently in the headphone space.

Latest Generation Dynamic Driver

The Eris is designed around HarmonicDyne’s latest generation of Ceramic-Metal High-Flux Magnetic Long-Stroke Dynamic Driver (CMHFMLS-DD). Featuring a 50mm ceramic-metal fusion diaphragm. This new dynamic driver is extremely responsive and delivers some of the best sound HarmonicDyne has to offer.

Semi-Closed Back Design

The Eris features HarmonicDyne’s M-type pressure relief system that passively ventilates the acoustic cavity. This system combines some of the benefits of closed back headphones, such as better sound isolation (roughly -5db) with passive airflow to achieve an open-sounding or “big stage” experience.

The Balanced Cable

Eris comes STANDARD with a 4.4mm custom balanced cable (3.5mm Dual Entry) made from customized solder-tuned single crystal copper wires. More costly to manufacture then traditional stock cables.

Two Listening Experiences

Due to the fully symmetrical design of the Eris, it is actually possible to reverse the cable left and right and use the headphone backwards to achieve a separate and unique listening experience.
