"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."
"I'm enjoying the lower ends so much that I'm starting to think I should not be enjoying songs this much for such a cheap IEM 😁"
"And the sound is no doubt the best one in this budget."

"Can be Equalised to boost bass and treble to sound like endgame bass iems like Punch audio Martillo . ... With EQ this can amaze people ."
"I've got them to where I am happy with the tuning. For mostly classic rock, metal, stuff not extremely bass heavy."
"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."

"This cable brought out the entirety of life for my purposes within the KZ Castor Pro (Silver Balanced). It added body to the whole sound profile and tamed the airy tin treble. ... It transformed the sound so much so that it is like having "ear radar" for getting the drop on enemies within Call of Duty Mobile - Battle Royale."

"W/ this setup, bass on the E20 and Castor Pro is absolutely ridiculous, leaving the Legato w/ shelf and Rosefinch w/shelf in the dust. Both sub and mid."

"I set them to the overblown bass setting for extra boom, and it’s awesome. ... for games, it's a good and fun experience."
"I tried the kz Castor pro silver it was really amazing when I played apex ... I can hear everything with the distance I can hear fights going on over the mountain enemies exact distances"
"I can pinpoint enemies in CoD, Rivals, or single player games like Oblivion."

"I have the KZ caster Pro, KZ x Angel ears, KZ × HBB DQ6S, TRN Conch and the TRN V10 Pro ♥ ... I'm so sad and frustrated - I've tried every single one of the recommendations, and I still have the same problem. My ears are too small, and they either hurt after very short time or the tips get stuck in my ear and my husband have to pull them out with tweeezers, I don't know what to do - I wanna love my IEMs and not bother people around me with being able to hear my music but I cannot find anything that fits T_T"
"Castor Pro is really uncomfortable. ... After a few minutes of using it, my right ear hurts a lot, and it becomes unbearable to use after a while."
"Couldn't use my castor pro because it hurt my ears. ... Turned out, the nozzles were too big for my ears. ... Castor Pro's is 0.5mm wider. It doesn't seem much, but the difference is huge."

"There appears to be a massive dip in the upper mids low treble on the castor pro bass ."
"all cymbals sound the same"
"Also when there ’s a lot of badly constructed treble in the track, the OG sounds better"

Dreydars 1.0i enjoy castor pro balance, thinking about getting duonic but missed good sale on it, would wait for good deal
They are nice, eartips and cable while not being great are ok to use, but if you feel like updating them, cheap kbear 07 eartips and qkz t1 would be good budget options, also if duonic is in your budget you better get it instead, it's overall improvement compared to castor albeit not as big
Trick_Media3510 1.0update: at the end i also buy the KZ Castor PRO 2DD (the target version) for $13. im gonna test both and return the one i like the least. i hope i made a good purchase >< https://preview.redd.it/1cle6ao1sn0g1.jpeg?width=1169&format=pjpg&auto=webp&s=c12457c85b91b84ce285a711c541e6adb25c3459
DSSLEGEND 0.6You can also get KZ Castor Harman Target edition, I use the same with my Boss Katana 50 and they have been great since the past year
Gloomy-Produce1472 0.6Kz castor harman target version or the tangzu wan'er. I've got both I prefer castor over wan'er but that's just me
I've had salnotes 7hz as my first iems and I'd say they felt flat to me ...flat enough that the music felt depressing to my ears . So I wouldn't recommend you to get an iem replicating music as is .... A lil fun element in listening don't hurt no one and ofc you don't have to go for punchy ones if that's not ur taste. You can check out KZ castor harman target which would be most suited for you, tangzu wan'er, else if you like a little bit of fun and vocal centricity ...Tanchjim bunny dsp it is ....this and good fit eartips !
33RhyvehR 0.3Still actually the 7HZ Zero 2. Bunnys spike in the uppers are not fun, Castor pro bass is a bit odd but enjoyable at least, waner 2 is tooo vocal. Pure and hexa are mid. Pure neither has enjoyable bass or mids. Hexa is shouty. EM6L is thin. Explorer is dark asf. The only one of these I've had moments of "Oh shit" and jumping up because I thought the sound was next to me, was from the Zero 2. My collection goes into the kilobucks
44RandomMan 0.3I had just the OG with Bass , very good The pro with bass is a different beast. If you want relaxed smooth thick bass , the OG is better , the pro has somewhat coloured enhanced mids and all cymbals sound the same . Imagine the old one note bass of cheap speakers , now flip this into treble . I prefer the OG bass than the pro bass
There appears to be a massive dip in the upper mids low treble on the castor pro bass . Also when there’s a lot of badly constructed treble in the track, the OG sounds better Another thing, at low volumes the OG carries the bass better I have both and like them both , but the OG version plays better on most tracks except where there is too much bass
abc133769 0.3if you have access to zvx pro i'd go for those otherwise i'd take the kz gale as a more balanced allrounder or caastor pro if you're a basshead
Acustomerme13 0.3My everyday beaters castor pro they are really cheap for the cable i just grab any good looking cheap in AliExpress also kunten is even cheaper than castor pro but sound like a 50$ iem
AdRich1865 0.3Buy kz castor pro.
AggravatingCustard39 0.3You are not the target market for them, they make entry level and midrange products at a very good price for performance rate . Eg, Kz Castor pro
As I said they are not for people who have a budget of 100$+, you are not the target market. 😅. You have tasted elixir so these would be like stale beer. These are for the poor chaps like me from 3rd world countries whose budget would be around $50 at max Kz's cater for newbies that want a good pair of IEMs for a cheap price. The castor is like 10-12 bucks . And it's very good relative to its competitors. Metal/resin body + dual drivers.
