Life Q30 Sound "crakling"

So i started using these headphones 1 month ago, they are really great but the sound “cracks” sometimes and it’s really annoying…
I don’t know how to describe it, it makes a sound that can hurt the ears (it did) like “electricity” and when it happens it doesn’t stop anymore (interval of 3-4 seconds each time) so each time I have to reset it about 3-4 times a day but it depends I don’t know why.
It happens most of the time time when I have the “piano” EQ but it does it even with the default one.
Does anyone have a solution ? (They are up to date and it is not broken at all)
