I’ve noticed that the music sounds best if I’ve had a good day, everything in my life is going well, I’ve exercised pretty hard that day, I have nothing left to get done that day, and it’s night time. If all of these things come together, it’s usually a recipe for a good listening session.
I’ve also noticed that its best to take a 10-15 minute break every hour or so from the music...
I’ve also noticed that I can pick up more detail in the music at low to medium volume levels. It’s not such an onslaught of sensory overload that I sometimes get at higher volumes, yet sometimes high volumes are whats needed to get me fully engaged in a musical experience.
I also like to listen first thing in the morning (or even if I’ve woken up in the middle of the night...low low ambient noise is a plus) when my ears and mind are totally fresh.
I even tried wearing shooting ear muffs (I know, I’m strange) for 30 minutes before listening in order to “prep” my ears. Akin to closing your eyes in the dark and picturing the darkest black you can, then reopening them and being able to see much better. I didn’t notice much of an improvement doing this particular method.
Last way I warm up my ears is with routinely cleaning them thoroughly with hydrogen peroxide and a steady stream of warm water to help loosen / soften ear wax buildup.
