The first step toward purity, where quality meets accessibility without compromise.

The renewed Simul interconnect and speaker cables were born in the spirit of clarity and naturalness. They embody nearly two decades of experience and experimentation: to let music flow freely and effortlessly, just as it comes to life when instruments are truly played.

The conductor material is a finely tuned silver-copper alloy.
In this unique balance, copper’s warm, full-bodied tones meet the shimmering detail of silver, creating a sound that remains both natural and precise, musical and analytical, with no compromises.

The insulation and outer layer have also been completely redesigned.
The PVC-free insulation and new construction, combined with a cotton covering, are not only an aesthetic innovation but a fundamental step forward: providing better mechanical damping, reduced external interference, and a sound that is cleaner, more natural, and free of any buildup in the mid and high ranges.

Simul is the evolution of nearly 20 years of development experience. The interconnect cables are the refined heirs of previous generations, while the speaker cables are entirely new designs – yet all carry Human Audio’s two decades of expertise and dedication.

Simul is the entry point into the world of Human Audio – where music doesn’t just play, it comes alive.
