Reference-Grade Personal Audio Cable | Available at Trimira Audio
The Nordost Blue Heaven Headphone Cable brings Nordost's Leif Series construction principles to high-performance personal audio. Designed as an upgrade over conventional stock headphone cables, it combines low-mass construction, flexible conductors, FEP insulation, and Nordost's Micro Mono-Filament technology.
The cable is engineered to provide a mechanically stable, low-loss connection between compatible headphones and headphone amplifiers, while its flexible construction makes it practical for desktop and dedicated headphone systems.
At Trimira Audio, we recommend the Nordost Blue Heaven Headphone Cable for listeners looking to upgrade the signal path between their audiophile headphones and headphone amplifier or portable source.
Key Features & Technological Innovations
Proprietary Micro Mono-Filament Construction
Each conductor incorporates Nordost's Micro Mono-Filament architecture, using FEP material around the conductor to create a low-contact dielectric environment.
34 AWG Litz Wire Geometry
The cable employs 4 × 34 AWG 7/42 Litz conductors using high-purity OFC copper.
The fine-strand construction provides excellent flexibility while maintaining a carefully controlled electrical path.
Integrated Aramid Fiber Strength Member
An internal Aramid fiber reinforcement provides mechanical strength and helps transfer pulling and flexing forces away from the conductors.
High-Purity Extruded FEP Dielectric
The translucent blue FEP insulation provides a lightweight, mechanically stable dielectric with low dielectric absorption.
Versatile Amplifier Termination
The standard amplifier end uses a gold-plated 3.5 mm stereo mini-plug, supplied with a screw-on 6.35 mm (1/4") adapter.
This provides compatibility with both portable and desktop headphone amplifiers.
Broad Headphone Compatibility
Custom headphone-side terminations are available for a range of headphone designs, including compatible models from:
- Sennheiser
- Audeze
- HiFiMAN
- Dan Clark Audio
- Focal
- Other compatible headphone manufacturers
Connector selection should be confirmed against the exact headphone model before ordering.
