Turns out I turned on my desktop amp accidentally so both the headphones and my desktop speakers (which I really like) were playing at the same time.
Maybe I should always listen this way?
😁😊
I lived trough the same accident...
At the times with my 8 headphones...
Now i listen only speakers/room though because of this "accident" which revealed the power of some reflections from outside the first wavefront coming from the headphone voice coils...
Room management is the useful control of reflections among other things...
My sound is better than my 8 heradphones , even with the same intimacy than with my headphones...
Amazing...
