First things first after trying many IEMs under 2k rupees like CCA CRA and CRA+ Blon Bl03 KZ EDX Ultra And Moondrop CHU and every earphones under 1000 rupees

The Zero have less bass quantity, but the bass is cleaner and tighter. Transients, micro-details, soundstage, instrument separation, and clarity are better on the Zero. However, the Zero are harsher and more sibilant.In some songs like Zaalima the Instruments separation is bit weak but in other songs instruments separation is good No budget segment royal rumble would be complete without mentioning the big Kahuna: the venerable BLON BL-03.

C100Si is bit Boomy tho realme buds 2 is similar sounds bit similar but it has better build quality Technicalities and resolution are better on the CHU, but they are markedly more sibilant. The CHU’s timbre sounds very nasal and unnatural compared to the more organic-sounding Wan’er. Where to BuyDoesn't require fiddling with the Equalizer (may be you'd want to pull down 8k hz a tad?). The e3000 definitely needs EQ, without which it can sound bloated / congested particularly on low powered sources
