Please only post your top 1 or 2 headphone mods , whatever best improved the sound, the biggest improvement.

Please also include the following:

1. the make and model of headphones,

Way too many to list. Lots and lots going back to 1980 when I did my first Senn mods.

You're surely not alone. I will revise my first post to request posting no more than 1 or 2. Thanks

Stax SR-Lambda Pro.
Removed the back-wave damping, which opened up the sound. It also made the sound stage a bit wider.

I'm curious, what do you mean by 'opened up the sound'? And what did it do to frequency response?

I think he meant it became less veiled.

Like if I remove a thin cloth covering the drivers (which I did). Making more of the sound shine through...

Bent the arms on my ES7 for Comfort and aesthetic issues.

Basic HD580 mods, Grills, Foam removed, etc.

Modded a pair of 5.1 Gaming head phones into $100. (The $100 has more bass, are more balanced and have an awesome sound stage).

Also tried to mod my MS-1s but they died. Will get some new MS-1s victims.

Haven't done anything myself, but just bought HFI-780 and asked seller to send it straight to s² audio for recabling.
