KZ Castor Pro
The KZ Castor Pro stands out under ₹2,000 for one unique reason — four hardware tuning switches that let you adjust bass, mids, and treble balance without any app. It is not the most technically resolving IEM at this price, but the ability to tune the sound to your preference is genuinely useful and fun to experiment with.

Quick Specs
| Spec | KZ Castor Pro | KZ ZSN Pro X |
|---|---|---|
| Price | ₹1,799 | ₹2,149 |
| PickRyt Score | 7/10 | 7/10 |
| Strength | 4 physical tuning switches let you shape the sound signature — the most customisable IEM under ₹2,000 | Punchy V-shaped bass and a detachable 0.75mm 2-pin cable make it a fun, upgrade-friendly budget hybrid with strong isolation |
| Weakness | Large plastic shell, tuning switch differences are subtle without trained ears, no mic standard | Treble can turn sharp on bright tracks, the tuning feels dated next to newer single-DD sets, and the large shell fits small ears awkwardly |
