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 the Endorphin is a uniquely engineered conductive surface formula allowing the rich well balanced capabilities of the Sennheiser HD800 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 the HD800 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 micro-phonic 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 HD800 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:

  • HD800 specific conductive surface material
  • Soft, light weight custom braid-hovering structure
  • Specialized non-conductive component preparation
  • Hand Made Wood or Integrated flex splitter
  • Stefan AudioArt Custom 1/4″ or 3.5-mm connectors
  • Quiet zero microphonic structure
  • Unmatched built quality and appearance

  1. Michael S. says:

    James, just a quick “second impression” re sound. I’ve been leaving the ‘phones on “burn-in” mode (Track 9 of the XLO CD) overnight and then listening for real for about an hour each evening. I find it difficult to believe there are the same headphones that I sent to you just a few weeks ago! I’m hearing SO much more into recordings I know well — it’s quite wonderful! I don’t know how much of what I’m hearing is from the HD800 headphone Ultra-Mod and how much is from the Hardwired Endorphin Headphone Cable, but it’s academic, I suppose. The overall effect is — WOW! And for the record, this is still just with digital playback — I can’t imagine what will happen once the analog from rig is back on-line!

  2. I wanted to tell you that yesterday I went to a friend’s house who bought the new Focal Utopia, and I decided to bring my modded Senns with me. I was really amazed to listen to them side by side (Utopia and modded HD800), and it was amazing how my modded HD800 blew the Utopias away in every level. The sound was much more transparent, more neutral, quicker and with much better detail. And we’re talking about a $4,000 model.

    My friend also had a stock HD800, which I also tried, and they were even worse than the Utopia. Strange as it may seem, all this time I had never had the chance to compare my Senns modded by you, with the stock ones. I guess it’s fair to say that the stock Utopia beat the stock HD800, but none of them comes close in its stock form to the HD800 modded by you with the endorphin hard-wired.
