These are my two BEST mods. ..
The Mikros90 modded to sound larger than stock,
And my modded es700woodie,
A combination of the Audio Technica ed9 housing with an es700 driver which combo gave me the closest thing to the fabled esw10jpn that I also own...
I will do a write up on that and make a thread as nothing comes closer. .
Anyway for portable "on-ears", nothing can top these three.
I also have the Onkyo 300 which I should include as a favorite but that dam connector broke so I will consider hard- wiring and it is not really as portable as these smaller units..
I would put the Onkyo 300 & AKG 545 at similar level for larger portables.
