Lol, that's funny!
No need to get bummed out. My scientific theories have been proved wrong before.
More importantly, there have been no reports of Solaris blowing up, so I'm sure you'll be fine. Even if the condensation occurs inside the case, it obviously doesn't hurt all that much. Of course, Dry Caddy will tell you otherwise.
About your Dunus, my guess is that the case makes contact with your skin, which keeps the temperature more even. (even though the Andromeda sits pretty flush to my head, it makes almost no physical contact with my ear, it's just the silicon tip holding it in place.. and the memory wire)
