Hi there, I decided to learn playing on piano so I bought Kawai KDP-90. I'm going to practice mostly on headphones so I want to buy one for this purpose. I was considering to grab DT990PRO 250ohm version but maybe you can recommend something else in similar price? Open or closed, no preference.

I would go with the HiFiMAN HE400S. It is just beautiful for piano and does not require an amp, which simplifies things somewhat. The DT990 250 would likely require an amp.

Hifiman HE560 is awful.  Sennheiser HD600s are pretty good, better than HD650s.  Any of the Audio-technicas above 900 series are solid choices.  
 
For the cheapest / best bang for your buck, I think the Samson SR850 is a very good choice.
