"The Castors are objectively better for mixing. ... So it's no longer true that you can't get good IEMs for under $50 that are good for mixing."
"im selling 3k$ worth of amps, dacs, headphones, iems just because I accidentaly heard Kz castor (harman, white, UP UP DOWN DOWN).. no joke ... way way way... im selling 3k$ worth of amps, dacs, headphones, iems just because I accidentaly heard Kz castor (harman, white)... ... but this one slaps for 10$ :-D"

"Silver version - A more versatile version of the EDC Pro, has the better soundstage a bit, can change sound feel from a neutral bright, neutral, and abit bassy. ... KZ Castor or Castor Pro (Harman, switches UUDD for music and DDDD for gaming)"
"they are the only IEM that I have tried with the ability to adjust the sound profile. ... There are little tiny sliders/switches on them so you can bump highs, mids, and lows up or down. ... It's kind of a neat feature if you want to try to taylor the sound a little bit to your liking."
"Very versatile with tuning and EQ"

I bought my first iem, castor neutral priced at 10$ and I am amazed with sound quality, better than my xm4. So I wanted to upgrade to potential end games and got myself a xenns tea pro for 340$ and a used wm1a and oh boy it's a clear upgrade in sound quality, and the tea pros are not fatiguing. Money well spent. I have now found my end game iem and will stick to this. Hope you find yours. 😇
I should have bought kefine klean instead of the kz castor.
Good point. Thats why i did tons of research after buying my first iem and dap which are kz castor and sony a35. Was overwhelmed with the vast number of iems and daps. Wanted to try it all in every price point but later decided it was not worth spending so much money so bought what i think is the best for me which was the wm1a and tea pros combo and sold my kz castor but kept my a35 as a backup. Now i can say i reached my endgame and no longer need to buy another device except when my current one breaks.
I'd pick harman neutral over bass-boosted. You can eq castor harman using peacegui and make a preset for gaming and music. The cx31993 is driverless so it'll be fine, personally i'd go with fiio ja11 purely because onboard eq.
eh the non bass version of kz castor is okay
Bro, should've bought better ones like kz castor x
For me, Wan'er is better than Castors. I've used both and prefer wan'er 8/10 times.
I would recommend kz castor silver(4k) or kz gale specifically for gaming(5k for type c variant). Don't get an edx pro for 3k it's not worth it at all. Another option is the gk kunten. Don't buy from temu or AliExpress tbh. Buy from a local seller. I can the contact info of the guy I bought my kz castor from if you want.
I have been producing with castor for almost a year before it broke and i will tell you how much improvement it gave to my mix. While it is still a cheap IEM it still gives a massive difference compared to cheapy pay at my local market. I think while training your ear is good you also have to take into account what gear you are using. Castor not only improved my mix somewhat but also improved my daily music commute experience. I think spending a little bit will not make you better in mixing overnight but it will at least help your mixing activities much more comfortable.
i have it its totally worth it if in pune try the audio store
I'm not sure I'd call the Cadenza a basshead tuning, but they certainly have plenty of bass. It gets deep and rumbly, with some punch but not as much as the Castor Bass (not sure about the Pro: apparently that's not as hard-hitting as the OG, which I have). The also have very smooth treble that's a touch darker than some similarly-tuned IEMs like the Chu 2, which adds to the overall warmth/bassiness, while they sill have good clarity, imaging, etc. Sometimes someone will complain that these have little or no bass and without fail it's because they aren't getting a proper seal. Make sure you try out all the tip sizes if you aren't hearing enough bass.
U will get more detail, and better quality in bass, trebble vocals. The performance will be better but for many ppl it won't be a 2x better experience if it's not they're preference. Aful explorer is my favorite iem. Love immersive, dark and chill experience that I can crank the fuck up and the music just surrounds. Love it May is my all rounder because it has a mic, was cheap and a usb-c cable. Hexa goes for sale as I don't like neutral iems. From budget ones I still one hola, piccolo and castor. Don't listen to neather as Explorer fits my preference almost perfectly as I listen to emotional osts quite exclusively recently, but it also does everything very well accept metal for me as it lucks the air
