KZ is a highly popular brand that has gained a lot of recognition in the audiophile community for its affordable yet high-quality In-ear monitors. They also offer after-market upgrades for IEMs, eartips, carry cases, and TWS wireless adapters.
I've been fond of music and specially the interstellar kind of songs and then I found the best way to experience it would be an IEM. Did some research and got to know two best ones below 2k range. Moondrop Chu 2 and castor pro. The buying experience with the audio store is pretty good too!!

Sound quality is good, But...
Overall sound quality is good and design is also lovable, but problem is only with side of the bud.. also it is quite heavy to wear up, easily get down after a movement.
One more issue is my product, it have gap in left side bud.

Exceptional Sound with Balanced Bass
I’m genuinely impressed. The sound quality is exceptional—crisp highs, clear mids, and a bass response that’s just right. It doesn’t overpower the mids or muddy the overall sound, which is a rare balance to strike in this price range.
🎧 Sound Signature: Tuned to the Harman Target with a tasteful bass boost. It adds warmth without sacrificing clarity, making it perfect for everything from vocals to electronic music.
🔊 Bass: Not too high, not too low—just enough to give depth without distortion. It complements the mids beautifully.
🛠️ Build Quality: Solid and premium-feeling. The fit is comfortable for long sessions, and the mic is a handy addition for calls or gaming.
Overall, it’s a fantastic value for the price. If you’re looking for an IEM that delivers refined audio with a touch of bass and excellent build quality, this one’s a winner.

Best among its price range. I think it's best value for money till 15k. And best overall sound quality under 10k. It's complete package. This is my first purchase before this, I used Sony WF-1000XM4 earbuds. This is gonna kill to its value for that impressive sound quality.

Hiby R8II DAP
Connoisseurs of good football often are heard saying Messi is from a different planet. The same applies to Hiby flagship ( in true sense)DAP R8 II. The brand has not spared any efforts to reach to thd pinnacle of build quality , aesthetics and last but not the least REFINEMENT OF AUDIO QUALITY which theAudiophiles expect to see at this level of grandeur and craftsmanship. If money is not a constraint and true love for Audio is present a second thought must not be shared for this- just go and grab this unit if theimpulses are there to be bathed in refinement of audio.
