I don't think it's my brain that adjusts, as when I had the PX25's I would leave Spotify running and go back to the house for an hour, then it sounded spot on, if I listened from cold it sounded distorted and thin, so I didn't bother until it warmed up. I reckon speakers need warming up too, especially if left in a cold room.
