I haven’t tested them myself AND their out of your budget range, buuuuut:
They’re a Danish (?) company and their headphones are supposedly easily repairable and have great sound. I know one person who has the „Prince“ but they’re an online friend, so I can’t test them myself. But that person is really happy.
So if my headphones ever need to be replaced, I’m thinking of getting these.
I don’t know if it’s open ear, but this is a European company that I stumbled upon a while ago (funnily enough, this is the second time I post about them in this community) :
