I actually did dream of headphone last night - CIEMs to be exact. I've had plenty of similar dreams but this was the second time CIEMs came up.
it was a blue pair of FitEars (could tell from the labelling and the shape of the indent outwards on the inside-facing part of the shell), that much I could discern. She said they were C435s but I got the feeling they were MH335DWs for whatever reason. A middle aged female wearing glasses gave them to me to try out, I actually recall the sensation of putting them on in my "dream state" quite vividly. But I kept trying to discern the sound that it was "supposed" to make and nothing came out, I was quite disappointed. But then the lady kept asking how I liked them so I had to politely nod my head and say that they were very good.
Then I found a cupboard (because somehow I could magically teleport from somewhere right into my bedroom - although we could've been in the bedroom the whole time), and inside of it was full of different IEMs, ones I've long since sold. The RE262s, the MTPCs. I rolled them in my hands, then I forget what had happened after as the dream had ended a few moments later.
If it was any other person I would've said they had gone crazy, but these dreams actually recur a lot for whatever reason (for whatever reason, the MTPCs ALWAYS comes up). And I know for a fact I've already gone crazy

My only regret is that I didn't get to hear how they sounded in my dream state.
