I've been considering modding my HD650s. It's my first real pair of audiophile headphones and I've been enjoying them very much. I own a SONY amp/audio-video control system (STR-DE925), nothing special or spectacular but it gets the job done for these cans. I have yet to find a decent compilation of mods and their descriptions, so I'm making this thread for that purpose. Here's all the information I've gathered so far on HD650 mods.
What I need help with is understanding what the mods do soundwise, and would appreciate any help describing them accurately. I have compiled a list of sound changes I've been able to find for the mods around head-fi and other places.
Coin Hole Mod: (irreversable) As it sounds, cutting a small hole in the middle of the foam.
