Finding a worthy successor for my Sennheiser IE80

I'm currently relistening to my trusty 10 year old IE80 and while they're still sounding brilliant they are starting to show their age, the paint is starting to chip and recently a nozzle broke clean off. I fortunately could glue that and they still work, but I think it's time for something new.

My budget is somewhere around 500€ (preferably from a shop in Europe, but not against ordering from outside of Europe) and while I do like high quality headphones I'm by no means an audiophile so earcomfort for me is more worth it than a bit higher audio quality. So casual listening while at work etc. are my main usecase. On the PC I use Beyerdynamics DT1990 Pro, so the IEMs would replace the "out and about" wireless headphones I use.

Thanks in advance!
