Thank you from the nice comments.
Operabuff, I am a Pole, I live in Krakow.
Hairspray foam discs lose small, quiet details treble.
In my opinion:
Pads HD 430 - bass ok, a little scene, poor location, nice vocals, a little nasal sound.
Pads HD 250 - bass ok (sometimes booming, losing control) big stage, good location, vocals a bit weaker (withdrawn), a little too sharp sound.
Pads HD 540 I reconstructed-fast and low bass, beautiful vocals, big scene, very good location, excellent presentation of the micro details. Natural sound.
Pads HD 540 II I was not listening.
