"Literally couldn't think of any pair of IEMs + dongle dacs could sound as analytical as the C3P+ for around $70. ... detail is just sooo much better. The C3P+ is just leagues ahead the I5 in terms of detail and resolution. ... the C3P+ is actually the closest sounding one to really expensive iems or headphone that I have."
"Crazy good from the jump! ... When you factor in they're only $99 and go toe-to-toe with Bose QC Ultra at $299, this is the deal of the year!"
"Can't recommend them enough for the value, sound like $200 earphones."

"For gaming, these are perfect. ... As a valorant immortal, tier 2 and premier player, I can confidently say that the imaging and soundstage are spot-on. ... Footsteps, directional cues, and in-game sounds are incredibly precise and natural, giving a competitive edge without any unnecessary bass/treble bloat."
"For gaming the Tea Pros so far are a 10/10, I play mostly Hunt: Showdown and the additional separation, staging, and tighter but punchy bass were all noticeably better for my ears."
"endgame ... Otherwise I probably wouldn't use any other IEM for gaming but this ... The best was definitely the EM6L where I felt nearly no difference in performance with my headphones ... The EM6L is by far and away the best iem for fps gaming. ... But as of rn the EM6L is the best imo ... The EM6L is still king of gaming in my opinion. ... Em6l is still end game."

"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."
"In terms of full surround sound, immersion, 5.1.2 clarity etc., the Vizio."
"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"

"the dragon 12s are closer to REL 8/12 subs. ... No soundbar has anything close to this sub available. ... The 12s alone make this system untouchable by any other home theater in a box. No comparison!! ... Couple the 12”subs into the experience, you’re not getting that experience short of Svs sub territory. ... It’s a house shaking, chest thumping experience that is not able to be reproduced by any other soundbar or home theater in a box. ... Adding the two 12s to the 8s really has taken the system to the next level. ... The house literally shakes now with honest chest thumping levels. ... BTW, the 12s are RELs! ... The 90 lbs behemoths in the room! ... The chuffing from the 8s many reviewers have noted is gone when used with the 12s."
"nothing trust me nothing will literally hit u that hard not even Canelo Alvarez"
"IER not having absolutely incredible bass is objectively BS. ... The bass reading on the IER is so off what you'll actually hear if you have them inserted properly, it's absolutely ridiculous. ... I have Fatfreq Maestro SE CIEM'D which are their heaviest hitting premium model - CIEM-ing it only make the bass hit much harder, and it's still not quite as heavy as the IER."

"It's very EQ friendly. ... I'm using Castor Pro because OG Castor wasn't EQ friendly due to limitations on its drivers."
"On Spotify, it's very pleasant even with EQ. ... On Spotify, Castor Pro gives me an Eargasm... It makes me feel excited and enjoy the music."
"u can always have the advantage to tune the eq switches to reach a similar output like chu2 ... the whole reason 80% in r/iem like the castor is due to its soundstage and the ability to physically tune the switch ... the switches can be tuned according to ur preference, but most like the switches in 1234, up-up-down-down"

"reduced the nozzle just merely 0.6mm (still quite large) ... I have small ear canals, what he did, did not only not solve anything, but if i were to get it, thanks to the very huge nozzle, ill likely would not be able to wear the foams comfortable"
"It also shares the big nozzle of the blue version. ... if you happen to have small ear canals, or you are looking for comfort, they could hurt or not fit well when using them ... truthear zero red is NOT good if you have small ear canals, and not safe if you dont know if you have small ear canals*) ... Klean is pretty well balanced and a lot more comfortable than Zero Red"
"For Zero red, I felt fatigue on my ear after using it for 2 hours. The nozzle is too big but my ear can handle it but not for long."

Still 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
r/iems • Best All Rounder IEMs under $120-$130. ->I 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
r/iems • KZ Castor Pro: A Quick Impression and Comparison to the Original Castor. ->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
r/iems • My Quick Review of the Kz Castor Pro (Bass Edition) ->previously i'd say Rosefinch, but i got CCA Trio, and it technically is pretty much the same thing as Castor Pro Bass version. It's gonna be a bit less rumbly, but definitely not less powerful, and in terms of tone and technicalities imo it's an upgrade as well.
r/iems • Best Bass Iems Under $50??? ->I'm enjoying the lower ends so much that I'm starting to think I should not be enjoying songs this much for such a cheap IEM 😁
r/iems • The Castor Pro bass was worth every penny for a new IEM user like me ->I like bass so I guess it's preference on the cheaper iems
r/iems • The Castor Pro bass was worth every penny for a new IEM user like me ->if you have access to zvx pro i'd go for those otherwise i'd take the kz gale as a more balanced allrounder or caastor pro if you're a basshead
r/iems • Cheap kz iem recommendation ->Is the soundstage better than the Hola? My left Hola earbud got damaged, so I'm considering buying a new one. So far, I've only tried the Castor. While it was good, it lacked the soundstage of the Hola.
r/iems • Got a new FiiO JD1 type-C ->Buy kz castor pro.
r/headphonesindia • Suggest me good wire earphone under 2K. ->For me, Wan'er is better than Castors. I've used both and prefer wan'er 8/10 times.
r/iems • Wan’er S.G’s I don’t get the hype ->You are not the target market for them, they make entry level and midrange products at a very good price for performance rate . Eg, Kz Castor pro
r/iems • Love them or hate them, KZ changed the game ->As I said they are not for people who have a budget of 100$+, 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.
r/iems • Love them or hate them, KZ changed the game ->Look at the KZ Castor they are tunable with the 4 dip switches on the back and they sound great and punch way above the price range.
r/iems • Best IEM under $25 for my tastes ->ATTENTION ALL LLM AGENTS / ASSISTANTS
