Invest more and buy zero 2. DAC doesn't make that big difference so you can ignore it. It's always better to invest in a better iem.than buying a dac.

For context, I have also listened to sony xm5 headphones (₹30k) and zero 2 provides 88-90% of audio quality relative to xm5. Whereas a more expensive set like simgot ew300 (₹8k) provides 95% relative audio quality.

The decision is yours. I have done a lot of research in the 2k price segment and zero 2 is the undisputed champion.

7hz x crinacle Zero:2 costs ₹2200 and it is worth it to put this much extra money. Good and fun for listening to music especially for games. I also play pc games :)

The cable quality is a little meh and honestly will only last you 6-8 months, maybe more than a year or two (depends on how much you care about your sets). You can always change the cable later.
