Is it worth upgrading to a new KZ?

Hello, I use KZ ZS10 Pro X headphones for normal listening to music in all styles and I wanted to know if it was worth upgrading to the new KZ ZAR or KZ ZAS headphones or if the difference is not significant

Why stay within KZ? It's mostly a marketing driven brand, many lower end models of other brands will sound better generally.

I wonder why a lot of people hates KZ when they sell very cheap. Sorry I'm just new to IEM hobby and this is what I noticed over the internet.

I have owned five KZ IEMs. I don't hate them but they are not as well tuned as other brands IEMs for the same price.
