– Now 4 Day Turnaround on HD800/800S Ultra-Modifcation –

Our new Ultra-Modification for the Sennheiser HD800/820 Headphones with the Endorphin Hardwired or Connector Version High-End Headphone Cable will expose the listener to the purest most spacious headphone experience available. Our HD800/820 Ultra-Mod/Endorphin headphone cable combination elevates the presentation of the great Sennheiser sonic signature to a new level that will exceed your highest expectations.

Stefan AudioArt’s headphone modifications are based on James Serdechny 35 years of experience as an engineer and musician. By removing or replacing key parts of the assembly of the HD800/820 headphones the issue of vibration control is properly address and the result is a headphone which performs at a significantly higher level. Every headphone mod we’ve come across on the market has been created by DIY individuals who operate on misguided notions. Their approach to adding materials to a headphone comes from their lack of knowledge of headphone design and the result yields degradation in the performance of the headphone which can be easily heard in a headphone system setup with properly designed cables and vibration control.

Key original internal and external parts of the HD800/HD820 headphones inhibit, distort and close-in the sound. The HD800 Ultra-mod is a proprietary process which entails removing specific parts from the stock HD800’s internal and external assembly, treating and remounting the drivers for optimal vibration control and replacing the driver mounting configuration with a Stefan AudioArt proprietary system.
