IMO no it's not worth it, not even close.

Given that you've said it's not in your price range and you would have to save for a long time... there is a very high chance that you will be disappointed. I know this might be an unpopular opinion here but flagship headphones are not worth their price for the vast majority of people. You're so far into diminishing returns territory at that price level, you can get something marginally worse for a fraction of the price.

If you had money to burn and were just trying to find something to spend it on, then yea whatever. It's not worth saving up for when you already have a good pair of headphones. That's just my opinion.
