Also, about EQing, do I get it right that you suggest toning down high frequencies in order to be able to raise the room ambience setting without altering the sound too much (as doing that increases high frequencies)?
Ya for starters just try the pads and the builtin presets. The pads are a must for me. Then once you're nice and acclimated with that sound you can try some eq. some small adjustments to various areas of treble made in real time while listening to music(like with eqapo or uapp you can turn a preset on/off with a single button and compare the sound). A small -2db q3 bell around 2-4khz, a -2db high shelf at 5-8khz, things like that.
Mod is 100% non destructive. The only caution with Audeze is slide the headphones off your head instead of pulling the cups outward as some of the plastic joint pieces can break.
Thinking of the baffles, what could still be useful is a felt ring with a cutout for the opening to the transducer to reduce some reflections off the cup housing/baffle. Ive found damping the actual output from the headphones to be of great affect for this virtualization since the rendering is simulating reflections
You cant really do anything for the reflections off your head, which is the reason why headphones sound brighter anyway and have to compensate the signal. But using deeper pads does reduce that initial reflections intensity and allow the loudspeaker emulation to function better, as does more angled pads by changing the vectors. On my desktop system I use the Dekoni LCD Velour pads. Giant angled tight knit velour with thick memory foam. You couldnt ask for a better pad for this type of audio.
I wrote this to someone else and I think accidently included it in a post to you then editted it out, but its fairly relevant for this discussion so:
I have a pair of he400s and took the rear grill out and replaced it with very open cell foam, lined the inside of cups with sorbothane, added melamine fazors to the rear magentics, and changed the pads. There were very intense reflections from the back of the driver off of the stock metal rear grill, the waveform coming out between the magnets, and the resonant plastic cups. Those mods drastically improved the treble performance and turn a really sharp bright sound into something very clean, still slightly metallic due to the nature of the driver, but much much more listenable with binaural rendering.
And yes, precisely, the more reverberant the sound the brighter the sound. Im able to push some of the brightest distorted **** metal through the more reverberant room presets in OOYH through a pair of extremely revealing transducers due to flattening out the headphones frequency response, compensating for HRTF, improving waveform, damping, and hrtf reflections(pads felt rings etc.), and removing all external noise from low noise low distortion circuitry(non feedback current signal), resulting in shockingly externalized and natural sounding loudspeaker emulation.

Correct, no upmixing or decoding is done by the Mobius, only thr virtualization.
