Not sure, they have what I would call a “cartridge” rather than a mount to connect earcup to earpad. A chunk of orange or blue plastic comes off with the pad, sooo Dekoni would have to either come up with matching paint jobs or one color that compliments both Mobeus variants.
It’s possible, just difficult.
You’re not dumb!
To put it simply, DSPs like the Sound Blaster X7 use Surround information to make a stereo output with the headphone-specific surround effect (which is called Binaural processing).
You have to go into the X7 app and check the settings for “Surround output,” but if you do that, then the headphone jacks, RCA out jacks, and optical out jacks will all have the Binaural processing effect “baked in.” Did you say earlier that you performed the Sparkos opamp upgrade on the X7? Well, opamp upgrades benefit the RCA outputs too, though I don’t think the Jotunheim is the best match for an HD 800 S anyway...
