I bought the KZ Castor thinking they were all the same, I didn't know that the version with more bass only came in black, I bought it in silver after I saw it was the Harman Kardon version 🤦‍♂️

You 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

I feel you, homie :D Just watch a load of reviews, scour reddit for all the info you can, then just pull the trigger on a cheap set that you instinctively feel might match your preferences..! Then, give your brain and ears time to get used to it, then go from there, IF you need to! (No need to go down the rabbit hole if you like what you have :D) Honestly, among the sets in my collection, one of my all time favorites is the original (ie: NOT the pro version) KZ Castor Harman (the silver one), it has great imaging and soundstage! Edits for typos PS: Ma sei italiano? :3

Try the og non-Pro KZ Castor silver (and set the switches to 1100 for a bit more bass!), you can buy it for basically spare change now, it will start giving you an idea, and it's great for gaming to boot! Yup this is all so subjective and solipsistic, but it's part of the fun! ps: yeah, the 'Vito', plus 'infinito' means infinite/neverending in italian as well, ahah

The og (NOT pro) kz castor harman (silver) in the 1100 configuration is still one of my favorites, even among more expensive sets

In all honesty, yes: I have the og Castor Harman, the Zvx pro, the Prx, the (CCA) Rhapsody, amd the AM16 Balanced, and they're all banger, banger sets. I've been lucky and haven't faced breaking QC issues, but then again, what brand doesn't have QC issues?

Kz 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 !

As someone who PEQ's a lot- the Castor bass punch, specifically from Castor OG, can't be replicated with just EQ. You can boost the bass that is there but it will not be the same quality of bass. Zero has better sub-bass but the mid-bass is much less and even for sub-bass I prefer Aoshida E20 or turning up the bass on Yu Xuan Ji.

From that list Castor or Castor Pro but honestly I prefer Vader Balanced, Zenith, AM16, and ZS12 Pro X as my favorite KZ IEMs.

This might be perfect for me, I really like bullet style IEMs, neutral "flat" tuning and i daily drive a Final E500 IEM. This particular IEM has significantly better resolution and less harsh than my previous IEMs — OG KZ Castor and Truthear GATe. I should consider this soon, If i'm looking for an upgrade from the Final E500 technical wise (better resolution, imaging and bass response). My only cons with Final E500 is when played with songs that have boomy bass, the low end distorts and its non removable cable so there's a limit with customization. Other than that, Final E500 is almost the perfect IEM for me without breaking the bank. Anyways, this IEM you reviewed might be a tad upgrade from my Final E500, I'll look more into it

I have the KZ Castor harman it’s okay overall a little flatish and bass is pretty absent base on my experience using it. You get less accessories when you buy it. I dont own the Tachjim bunny but i saw the accessories it includes, it seems pretty much a good pick over the castor for the value imo

The Jm6 is pretty good with most IEMs, I cant really recommend which IEM cause it depends on your taste in sound signature. Well if i had to suggest something, for me i would put the Castor out of the list just for its lack of accessories upon unboxing it. You would be underwhelmed since it only gives u, 3 pairs of eartips to try, a pin to adjust the tuning sound and IEM themselves.

Personally, at 2k INR. None will have the clarity and details for some and many audiophiles. It kinda starts at least at the 4k-5k INR or above. If you want some details in this price range, go with a bright sound signature or V-shaped with prominent bright or trebles.

Castor Pro (Silver) might be touch bit brighter (abit more leaning towards neutral bright) than the OG Castor Silver, OG Silver seems to have a little bit more smoother sound experience than the Pro Silver. OG Silver, even in FR graphs is more versatile from neutral bright to a Mild-V warm-ish tuning. On the Tangzu Wan'er SG 1, yes its really warm and chill sound experience, though same with your guess it sounded abit too relaxed. Wan'er SG 2 changed that, so you can definitely go for that one as well. If you like bass, then Castor Bass definitely. Imaging wise its better than Tangzu Wan'er SG 1, though male vocals gets drowned, female vocals does not get affected as much. This based on my own personal experience on all 3 https://preview.redd.it/pq76zelzj8xf1.jpeg?width=9720&format=pjpg&auto=webp&s=1e9a811c03703d0c885fd03d7a806392ba2ec491 Though in the end, these are just subjective and personal opinions, everything will end up on your own preferences, likes, and dislikes.

The original EDX Pro is really more on the V-shaped bright tuning, and many don't like its bright tuning. If you really like bass, Castor Harman is not your IEM. I would either suggest going to like Saga Bass or Castor Bass, or Dawn. Castor Harman (1100 switches), Gale, EDC Pro, EDX Pro 2, and Saga Balanced is more leaning towards balanced-ish tuning. Castor Harman (0000 switches) is more leaning to mild-V shaped bright, (0011 switches) neutral bright tuning Terms of improvement or any differences, if you want versatility and easy to adjust to almost any tuning, go for the Castor Harman (tuning switches and EQ) If you want to not fiddle with switches and/or EQ, go for the EDC Pro, EDX Pro 2, and Saga series.

What's your top IEMs there Personally my top faves are - AM16 Balanced - OG Castor Harman (Silver) - EDC Pro EDC Pro sounded a little bit too upper midrange bright for me with average bass impact, lacks enough details for me. OG Castor Harman sounds good at 1100 setting, but it sounded thin overall. Closest sound experience I have with it is the Truthear Hexa. AM16 Balanced seems to be the least excessive upper midrange bright for me (even vs EDC Pro), and has the wider imaging both horizontal and vertical (almost holographic)

|WARM|BALANCED-ish|BRIGHT| |:-|:-|:-| |Tangzu Wan'er SG (neutral warm)|Moondrop Chu 2 (mild v-bright-ish)|7Hz Salnotes Zero (neutral bright)| |Kiwi Ears Cadenza (neutral warm, with a touch of bright)||Simgot EW200 (mild v-bright)| All of them are good at their price point, but basing on your other IEMs, you prefer a mild-v tuning, either abit bright or abit warm. * KZ Castor Harman (Silver) which is a neutral bright to mild v-warm from switches * 7Hz x Crinacle Salnotes Zero 2 which is a mild v-balanced with a warm-ish feel * KZ EDC Pro is a u-balanced with a touch of warmness Kiwi Ears Cadenza has better brightness and air vs Tanzgu Wan'er SG, and personally experienced some minimal lower midrange mud with the original Tangzu Wan'er SG. Tangzu Wan'er SG 2 kinda fixed most of the issues with the original Wan'er SG, but its still a neutral warm IEM. Simgot EW200 has more energetic and brighter sound signature than KZ Castor Silver (Harman), but KZ Castor Silver has better soundstage and image separation vs Simgot EW200. Moondrop Chu 2 is the smallest on all of these, but might lack overall sound experience abit vs both the KZ Castor Silver and 7Hz x Crinacle Salnotes Zero 2. 7Hz Salnotes Zero is more neutral bright, lacks bass impact vs 7Hz x Crinacle Salnotes Zero 2. (fairly similar to KZ Castor Silver at DDUU/DDDU switches) * So if you want a little bit more warmness but retaining some balanced feel, Kiwi Ears Cadenza * If you want more treble energy and abit more analytical, Simgot EW200 * If you want a small IEM, Moondrop Chu 2

then go for a single DD IEM or 2DD with neutral or harman/harman-ish tuning, avoid going hybrids or planars. With the price range there are decently ones but I am unsure if they include a cable with included microphone, excluding every IEM we already listed before: * Kefine Klean \* * Tripowin Vivace \* * Moondrop Lan * Inawaken Dawn Ms \* * Kinera Celest Wyvern Pro * Tanchjim Bunny * Tangzu Wan'er SG 2 \* * Simgot EW100/EW100P * ZiiGaat Nuo \* * Truthear Gate \* * ISN Neo 1 \* * BLON BL-03 * BLON BL-03 II * BLON BL-05 * EPZ Q5 Pro \* * TKZK TK-02 * KBEar KB01 * KBEar KB02 \* * KZ Castor Harman (Silver) \* * KZ Castor Pro Harman (Silver) * KZ EDC Pro (\* recommend)

difference is more into maturity, general sound experience, and refinement. but it definitely depends on your preference tuning(s). I previously came from the original KZ Castors (both Bass and Silver Harman), then jumped to KZ AM16 Balanced, but I have already experienced few higher end IEMs around 50-200 USD. AM16 Balanced, especially if bought on a discount or at low price (just like mine at $33 locally here in the Philippines, but in the US it might be around $50-60). Better terms of detail retrieval, instrument separation, and "soundstage" vs the Castors (even if I EQ them to a similar preference EQ I like) But with a little bit more pricy set than the AM16 Balanced, because of its deep V-shape tuning and a little bit more refinement on those more expensive sets, those sets sound better overall. (specifically Ziigaat Odyssey 1) Though personally the AM16 Balanced with PEQ is getting there, sounds wonderful, though definitely those two sets are better, But definitely I know now what to upgrade to and most likely I know what are my end game sets. Until I don't need to EQ. My Mild-V/U shape EQ is around the Xenns Mangird Tea Pro and Ziigaat Odyssey 1. https://preview.redd.it/enkhr59aqhyf1.png?width=2400&format=png&auto=webp&s=35e8f417e92d2acc4f2be3885944fbb1a67f9a52

EDX Pro 2 and Saga Bass would definitely be a slightly more warmer set than EDC Pro. EDC Pro would be similar-ish in bass and mids with the EDX Pro 2, but a brighter treble, abit closer to balanced than warm or bright. But the EDC Pro was original reference tuning for many newer KZ IEMs, like the EDX Pro 2 and Saga Bass. They just refined the sound overtime, Zenith was the pinnacle of that tuning, especially alot of people really preferred the warmer sound. Even other KZs have been tuned to a tamer treble than classic KZ sets. Though recent new new releases have been using the Castor and Castor Pro Bass tuning with refinements on treble, and bass for the bass versions of the new KZ IEMs. https://preview.redd.it/rwodxqaqc3yf1.png?width=2400&format=png&auto=webp&s=cef5c06819544d7d3340234c1640b7dc24e72474

7Hz Zero 2 is good on gaming. With the KZ Castor (it depends on what Castor you wanted) as there are 2 version of the Castor. Silver Harman Tuned and Black Bass Boosted Tuned: Black Bass Boosted Tuned is usually recommended by majority of the YouTuber reviewers, but its only great for EDM, Hip-Hop, and Rap music and not so good for competitive gaming personally, but great for single player games. Silver Harman Tuned is more versatile, can be tuned either for gaming and/or music. And can handle more than the Bass Improved version and also decent for general gaming as well.

terms of vocals, nothing really beats the Tangzu Wan'er SG or the Wan'er 2. Maybe abit of treble, sparkles, and soundstage, that would be KZ Castor Silver. But vocals is still better for the Wan'er SG/Wan'er 2.

I am doing the reverse from you, I came from bassy IEMs to neutral or neutral-ish. My old daily driver was the QKZ AK6 Pro (left most, too boomy for my ears now) Then switched to the KZ Castor Bass (Very very V-shaped, big bass and big treble) -> Tested Tangzu Wan'er SG (Neutral Warm on my ears) -> KZ EDC Pro (U-shaped) -> Tested then switched to the KZ Castor Silver (Neutral Bright IEM) https://preview.redd.it/7fb6i40ommve1.png?width=8100&format=png&auto=webp&s=5639f5828253e1796037c4592d784a93bd3eb8b3

I don't know much about the ZS10 Pro, but basing on the squiglink. Wan'er 2 is more of a neutral warm, safe tuning (minimal treble) IEM Zero 2 is a mild V-shaped IEM, while not causing issues with the midrange that much ZS10 Pro is more V-shaped than the Castor Silver, and is treble brighter-ish and has abit more bass than the Silver but lacks bass vs the Bass version. In the end it really depends on your sound preference, music genres you listen in general, and comfort level on an IEM. I would definitely suggest to buy the Wan'er SG and the 7hz x Crinacle Salnotes Zero 2 as well being those two are also cheap IEMs under $20. But if you cannot buy another one, if you have friends or people who can let you try their Wan'er or Zero 2. Same with u/Mrs_Doyles_Teabags, the IEM world is a journey to enjoy, and good luck on your IEM paths you take!

Taurus is really tuned for a more neutral-ish or neutral bright preference. Its close to my JM-1 +10 dB bass shelf PEQ of my AM16 Balanced. But for my mild-v preference, ill rather pick OG Castor Harman at 1100 or Castor Pro Bass for more bass-focused tuning. Or just use my AM16 Balanced with no EQ, Taurus would just be a side or downgrade personally. But I know some will buy this set as their first.

12 months ago

They are for the most part similar in general sound experience and tuning. Just that Castor Pro has abit more clarity and minor details vs the original. Though the Pro is abit more larger in size and abit heavier. Like a little bit. Both are good tbh, though I personally go for the og version. If you want less treble with them, then you go for UUDD switches.

I have seen a comment (maybe from Audio Amigo) where the Soundbrenner might just be a rebadged TRN ST2 shells with an additional BA driver. Seen frequency response graphs of it somewhere from ASR Forums, wacky and maybe shouty and shrilly graph. https://preview.redd.it/05hgzaaiqxqf1.png?width=2400&format=png&auto=webp&s=bc1d239095b5772b4ab21beb2e973abb64f6a65d I would personally stay away from the Soundbrenner if this is the actual graph, I would rather personally use my KZ Castor, AM16 Balanced, or my EDC Pro over this. In your case, go ahead and buy the Kefine Klean!

Newer KZ sets like the ZS10 Pro 2 are semi-open backs, but they are not really open-backs they still has significant noise cancellation passively. All because of eartip rolling, invest on other eartips. I myself has the KZ Castor, it has a big hole on its bottom with filters. You could kinda hear stuffs outside a bit, but with the right eartips and volume you can't even hear the outside even people yelling.

Wait for your brain to get used to one IEM first, this happened to me. My original IEM was the QKZ AK6 Pro like yours (just the pink and blue one). I have used that for years as my daily driver abused IEM. Still works haha, until I end up buying the KZ Castor Bass. After few weeks, I noticed the QKZ sounded duller and has less clarity. It gotten way way worse as soon as I swapped to the KZ Castor Harman, which has way less bass than both. I ended up liking the Castor Harman vs both the Castor Bass and AK6 Pro. Now the QKZ just sounds like mud for me, too much bass.

i bought many KZ for my commuting beater set the one that i like and keep is Eda Balanced, OG Castor Harman, KZ ZVX Pro, and GK Kunten its the cheaper set as i don't baby them during commute or outing, so if one of them having issue or broke i don't have mild panic mid commute like when i bring my $100+ set. i've bought others (EDX PRO X, EDC Pro, Castor Harman Pro, and others) but mostly i gave them away. KZ is mostly side grading, so buying enmmase like this is not wise move. i suppose it could be fun tough.
