Our Zeno headphone cables are well-established as a significant upgrade over the cables typically bundled with ‘audiophile’ headphones.
Zeno Harmonic raises the performance standard still further, a fully-balanced design incorporating our Grun Coherent Earth System, created to complement the world’s highest fidelity headphones.

Ultimate performance cables for ‘high-end’ headphones.

‘High-end’ headphones continue to grow in popularity, but it’s still the case that the great majority of original cables supplied with even very expensive models fall short of delivering the full performance potential of the headphone itself.

The Zeno Harmonic cable addresses this by combining high purity OCC copper conductors in a true dual-balanced design with our Grun Coherent Earthing System which provides a reference earth point when attached to either your amplifier or mains ground.

The result is a drop in EMI-induced background noise levels to an unprecedented level in a headphone system, revealing the true dynamic range of your headphones.

Zeno Harmonic features our low-mass, wide bandwidth 4 (OCC) pin XLR connector with our proven cold-weld (precision-crimped) solder-free construction methods, the objective being to produce a continuous high-integrity signal path avoiding the breaks in material continuity which degrade ultimate fidelity.

Zeno is supplied as standard with a 1m Grun cable and spade tag adapter for connection to the ground post on your amplifier. A still higher level of performance can be obtained via an optional Grun mains adapter, typically used in a spare socket on your mains distribution block. A high quality XLR–6.3mm jack-plug adaptor is also included with each Zeno Harmonic cable.

Zeno Harmonic is a premium replacement cable for dynamic headphones (not electrostatics) from most audiophile brands. If you don’t see your brand listed, please contact us – because Atlas hand-assemble in-house to order, we can accommodate most specific termination or custom-build requests.

Standard lengths available are 2, 2.5 & 3m, with custom lengths and the option of our ‘Luxe’ premium leather finish available on request.



Low-mass OCC pin XLR with ‘cold-weld’ terminations, reducing the number of materials and break points in the signal path, resulting in more consistent construction and improved audio performance

OCC Copper

OCC (Ohno Continuous Casting) process was developed by Professor Ohno, from the Chiba Institute of Technology, to manufacture a very high purity single grain copper or silver. There are only a handful of companies in the world manufacturing via this method.


Microporous PTFE (Teflon™) is a unique, low density dielectric material, phase stable at room temperature, which offers significant performance improvements over solid PTFE (Teflon™) dielectric designs.

Dual Symmetrical (balanced)

Central conductor (signal path) surrounded by dielectric material encased within a circular conducting screen which acts as the signal return path.
