Stefan AudioArt HD650/600/580/XXX Modification



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 HD650/600/580 headphones the issue of vibration control is properly address and the result is a headphone which performs at a 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 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.

Information coming soon.
