Have you read through the dedicated thread in sound city?

It's worth a look just to see how good those headphones are. I also own a pair of them. It's a bit of a long read but has a lot of info about them and how good they are for the money.
They are also on inner fidelity's wall of fame. Which means he rates them as the best open cans in the world at their price point.

I use mine for immersive gaming, music and movies. There RRP is £299 ($499 in America) I believe in the UK (available for much cheaper though, in fact roughly half that price).
I used to use HD595's for competitive gaming but selling them (on the members market) as I have upgraded to a newer version of them.
The fidelio X1's are the best "all round" home headphone you can buy at any price point IMO simply because they are easier to drive than all the more expensive options apart from the HE400.
They should open up with use, you should see their sound improve over time, I believe they peak after 100 hours of use (burn in period). So things should sound even better once you get more hours on them.
I pretty much now have all my "end game" cans, that's me done, no need to buy another headphone again, just need to look after these and they should last me a lifetime.
I'm sure you agree the build quality, sound, comfort and feeling you get from the X1's is better than any gaming headset you have ever used in the past. The fact you can also use them for anything (not just gaming) is a huge plus point and that way you can enjoy them even more.
