Sound is a personal subjective experience. In my journey, I started with the expensive brands (before chi-fi iems exploded) with all different types of drivers: BA, planar, electrostatic, and dynamic. Right now, I can buy several pairs of chi-fi sets for the price of one of the other brands. UE (before logitech buyout), Etymotic, SHURE, Klipsh, and Sony were the brands I tried. After that, I tried a brand called 1more. After over 3 dozen pairs, what I finally found out is that I prefer IEMs with only dynamic drivers. This one fits the bill. It sounds to me most like the speakers I listened to growing up - which were mostly AR while they were still AR in the 1970s. Again, music is very subjective and it seems like my preference has converged on IEMs with 2 or more dynamic drivers per ear and no other type of driver. The brands I tend to buy are CCA, Kbear, Revonext, and TRN. The TRN V90s were my goto pair until I saw these dynamic only multiple driver models. I bought every pair that was multiple dynamic drivers under a specific price point. This model was one of them. These sound most like speakers to me and all 2-3 dynamic driver models I've listened to fit the bill and I regularly use all of them. The difference is really in the shell construction and the presence of the dip switches for passive EQ. For gaming, I use very light ones with transparent plastic shells and no dip switches. If I want to monitor a vocal performance, I'll use this model or one like it. These sound most like the AR-3a that I listened to during my younger influential years and I suppose, my brain think that's the way things should sound. I still have the speakers, but they are heavy and huge and really difficult to drive - so they stay in the basement. For my home theater setup, I use the smaller speakers (dynamic woofer and dome tweeter) and a sub. But the AR-3a and these iems still sound better, except the ARs and the IEMs are only 2.0.

The KZ Castor IEMs genuinely surprised me. For the price, I expected “okay” sound, but these came through like they were auditioning for a promotion. The bass is punchy and present without drowning everything else. The mids are clear, vocals sound clean, and the highs stay smooth without turning into ear-shredding sparkle. Legit balanced. Comfort is solid too. I wore these for hours while working and forgot they were even in. The build quality feels reliable, not luxury, but definitely way better than what you’d expect at this tier. The cable works fine and doesn’t fight me, which is refreshing. The value here is the real highlight. You’re getting entry-level audiophile performance without having to sell a kidney. If you want something that sounds great, feels comfortable, and doesn’t make your wallet cry, the Castor is a smart move. Zero regrets. Would buy again. These IEMs absolutely understood the assignment.
