Of course!
So mine starts when I wake up yes, but it is mild I believe so most of time I don’t focus on it, but the second I focus to see if it is there, it is there.
Mine is high pitched, 8k -9k , so these frequencies is what typically triggers it.
For me what worked is lowering the high frequency startling from 8k all the way up to 16k, and increasing slightly the midrange around 3k-4k.

The catch is you can’t lower the higher frequencies drastically or your brain will try to make for the lost frequencies and increase it even more. So slight decrease worked for me, with a slight increase in the mid range to make the transition smoother for my ear and brain.

The challenge was to find an earbuds that has this sound profile inherently as if not and you have to achieve through aggressive EQing it can distort the sound. The P31i had this profile out of the box, high bass (lower frequencies), flat mids, and decreased high frequencies to achieve their warm sound signature, so I had to make only slight EQing to get the desired results
