Well my current headphone Ive had for very long, so long that I don't remember when bought them.
It's the HD212 pro, maybe Ive had them for 10years.
There is a good chance that once I buy new headphone I'll have them for 5+ years, maybe 10+ years(!).
So It's not impossible for me to pay 4-500 euro's for them aslong as it's worth it for my usage.
The Denon D7000 got according to MLE:
Fun:10/10, Competitive: 8.5
Those might be a candidate, but I do want to try open headphones never had headphones besides HD 212 Pro :)
