Best IEMs under 2k with mic?

I'm a complete beginner to them, but looking for IEMS that I can use for gaming on my PC and mobile as well as other media consumption. I play with my friends so I need a decent mic as well.

I don't really care about bass but good vocals is a must.

So far KZ Castor seems like a good choice but let if you have other recommendations then help me out, thanks!

Oh and also, which store should I purchase them from? ConceptKart seems great but I heard they have terrible after service.
