So when I first got this headset a few weeks ago, with the JDS Atom amp and dac, I wasn't that impressed. I was like "this barely sounds better than my $180 Plantronics gaming headset. But after about 9 hours of listening, it easily beats the Plantronics. Did my ears adjust? I'm thinking the headset "broke in" I know some people debate whether that's a thing or not, I think it is.
Your ears forget what your most recent headphone sounds like, but your Brain chemically remembers.
Your brain is one big chemical mixing board.
Its like, when you hear a song, and your brain remembers the song. That is brain chemistry doing that.
Thats not your ears remembering it, that is your brain chemistry analyzing it as "How its perceived", as a chemical reaction that is based on neurotransmitters, ect.
So, your brain remembers how it hears a sound, and that sets it.
When you then change what you brain is hearing, when you give it a new headphone sound, then the brain has to re-set and does, and this is the adjustment that you are perceiving.
Its not brain burn in, its a brain chemistry reset.
This is why when you try to listen to 3-4 sets of headphones, you usualy have the experience of none of them sounding good., or sounding right.
That is the brain chemistry in flux, trying to reset, and can't because you keep giving it no chance to re-set.
The brain hears the same way it thinks.....its "chemical analysis", and when you keep flipping headphones around, you are causing the brain to keep adjusting its "hearing chemistry"......and that is usually going to sound like confusion.., which is why a old set of headphones you like will sound like garbage, after you try the new set and flip back to the old favorite.
You have put your brain chemistry into flux, and the result is........>"this usually sounds great, but now it sounds yuck".
This is why you need to never listen to any headphones on the day you are getting a new set
Always let the new set be the hearing chemistry reset, vs, confusing the reset.
