The Stefan AudioArt Endorphin is a new innovative high-end headphone cable which take our current E-Series audiophile headphone cable design to the next level with unrivaled performance and comfort and will outperform any other headphone cable on the market regardless of price.

The most important information we have gained in over 12 years of headphone cable design comes from our customers. Hundreds of serious listeners have reported back to us indicating that the sum of all the improvements offered by our audiophile, high-end and ultra high-end headphone cables translates into a unique emotionally involved listening experience with unrivaled realism and purity.

The heart of new Endorphin is a uniquely engineered conductive surface formula allowing the rich well balanced capabilities of the Sennheiser HD650/600/580 to be experienced with impact and emotional involving characteristics. We designed and tested dozens of our own conductive surface formulas which consisted of the purest copper available combined with proprietary conductive enhancing material so this group of headphones would perform at the highest level possible with optimal user comfort. This approach opposes all other headphone cable manufacturers who just select “off the shelf” materials which in turn do not offer comprehensive solutions to sonic and ergonomic improvement.

The soul of the new SAA Endorphin is achieved by engineering a headphone cable with 90% less non-conductive material which lowers the resistance to the audio signal and increases the richness, clarity and definition across the audio spectrum. In addition the soundstage presentation opens-up to expose the listener to music which becomes truly engaging and captivating. Ergonomically, the structure of new Endorphin is light and soft which eliminates the microphonic characteristics normally associated with headphone cables.

Three Connector options are available each with optional Wood Splitters (see drop down menu above for all combinations) :

  • –  Multi-treated Neutrik Professional 1/4″ for connection to headphone amp.
  • –  Multi-treated Switchcraft Professional 3.5-mm for connection to headphone amp.
  • –  SAA Ebony/ Cocobolo Wood Shell 1/4″ for connection to headphone amp.

Our custom handmade/hand polished ebony/cocobolo wood 1/4″ connector will improve the sonic performance of the HD650/600/580 headphones as it will present the music in a more natural/organic fashion, display greater transparency and reveal subtle inner detail.

No other headphone cable available is engineered for sonic performance and user comfort like the Stefan AudioArt Endorphin:

  • HD650/600/580 specific conductive surface material
  • Soft, light weight custom braid-hovering structure
  • Specialized non-conductive component preparation
  • Integrated flex splitter
  • Custom treated Pro 1/4″ or 3.5-mm connector
  • Quiet zero microphonic structure
  • Unmatched built quality and appearance

The Endorphin High-End headphone cable is available in custom lengths. Please call 860-521-2563 or send an email to stefanaudioart@yahoo.com.

  1. Guglielmo says:

    First of all I was happy to verify at a first glance the high level of craftsmanship done and the relevant excellent quality of used material: the cable is soft and comfortable and the cocobolo split and connector shell are very attractive with their warm wood-grain and smooth bodies.

    I see that the headset is now gracefully lightened without the all around original bezels and internal grille.

    And finally my very first listening impressions.

    I have the chance to own a master tape copy of a Rachmaninov Piano Concerto whose music I know very well being one of my preferred classical title. By the way I own several LPs of this same title as well but the tape played on a professional Studer machine outclasses any – even audiophile – vinyl.

    This is the first time that I can withstand the opening crescendo without need of reducing volume due to hidden but somewhere present distortion. Also my original HD600 was quite faithful to reproduced source but always sported some lacks in dynamic and 3D reconstruction. Presently with Endorphine cable and all the ancillaries related some veil even vague is definitely fallen and the sound-stage is huger with impressive dynamic never reached before.

    Also micro information are more evident and in main place giving a perfect perspective of what we are listening and how the instruments set-up was made by sound engineers. The focus is finally dramatic now and the presence of recorded material is astonishing at all.

    Actually I was tempted in the past to swap my HD 600 in favor of a superior model (HD1000 for instance) but luckily I considered instead to improve the original one in my hands. And I am very happy now because even keeping the original sound philosophy that I like very much I got the occasion to improve those features enhancing the potentiality of musical enjoyment with the same headset. No need for more further improvement!

    I read that the break-in period is quite long so I am prepared to get even more exalted these positive impressions.

    Many compliments for your excellent sound engineering projects and for your relevant state of the art products!
