The Meze 99 Neo should work well (or a pair of Meze 99 Classics secondhand, to save a few bucks). The Hifiman He-400i are a good pick as well, but I'm not sure how much they cost in Norway. They go on sale for $250 in the US all the time.
Those are two popular choices in that price range. The Focal Listen is also very good, but they're not as bassy as the DT990, so I'm not sure if they have the right sound signature for you.
Meze headphones are nowhere to be found in Norway unfortunately. The HiFiman HE-400i is currently on sale for $442. I'm not really into the differences between the HE-400-something, but I've seen the HE-400 used as low as $190. Focal Listen is priced at ~$250, but I think they'd might be a bit boring?
