Need help upgrading

I live in india and currently main the moodrop aria 2 Looking to upgrade to iems below 50,000 inr (~500 usd) Been looking at the following iems

Blessing 3, Studio 4, Mega5est, Performer 5+2/ performer 8, Davinci, Dita project m, Moondrop variations

If possible please also let me know where i can audition these in/around mumbai (ie if there is a place other than headphonezone)

Mainly looking for a neutral iem that is not necessarily boring i.e wouldnt mind a slight bass boost

Also confused about wether or not to get a DAP (mainly looking at hiby r4) Thanks!
