Eryx
4.4mm Balanced Earphone Upgrade Cable
Pure & Authentic Connection
An earphone cable serves as the transmission path for analog signals, and the material and structure of conductors directly affect the sound dynamics and restoration accuracy. Music signals inherently contain rich details, but not all of these details fit the auditory experience. Different from the straightforward signal transmission of traditional conductors, Eryx can accurately eliminate the interference of secondary details and restore the true nature of music, making the mid-bass sound mellower and the treble performance crisper.
Quad-Conductor Hybrid Design
German OFC paired with OCC creates outstanding sound weight and fullness, while pure silver combined with gold-plated OCC enhances signal transmission speed and clarity. Through the hybrid stranding of these four premium conductors, Eryx achieves outstanding prominence in both main instrumental expression and vocal reproduction.
Red Sandalwood & Titanium Alloy Construction
Eryx is equipped with high-density rosewood paired with titanium alloy as its exclusive components, two premium materials widely recognized in high-fidelity audio systems. Featuring inherent damping properties, red sandalwood effectively absorbs micro-vibrations generated by current drive and air sound pressure during signal transmission. This stabilizes signal delivery, minimizes subtle distortion and phase shift, ensuring a purer and more accurate sound output.
Interchangeable Pin System
Eryx integrates the standard Nyx Pin interchangeable pin system, coming complete with one set of 0.78 2pin long pins, one set of 0.78 2pin flat pins, and one set of MMCX pins. This versatile design ensures wide compatibility with a variety of in-ear monitors, meeting diverse connection demands.
Pentaconn OFC Plug
The OFC version of Eryx adopts a gold-plated oxygen-free copper plug supplied by Pentaconn. In comparison with rhodium-plated plug versions, it delivers a more gorgeous, refined and lush sonic signature, further enhancing the overall high-fidelity listening experience.
