# The Looks

Let's get the easiest thing to see about this IEM off to a start. It looks amazing, it's one of my favorites IEM in terms of looks, the Alpha&Omega Omega being my favorite (but with a sound signature I would not like). The pictures I have taken of it is not a good representation of it, it looks so pretty the way it looks in real life and how light reflects off the red flakes of the IEM. The case with the insert also does a good job of showing off the IEM and how good it looks if you use to use it. The only thing that would make it so much better out of the box is a cable that looks just as good. The cable that comes with the IEM is a grey cable and doesn't wow me like the shell of the IEM.

# How I Feel About the IEM and the Lack of a Dynamic Driver.

It's my first IEM I've own that doesn't have a dynamic driver in it (it has 6 BA + 1 EST) and it took me a long time to write a review just so I can spend time with it and with other IEM with dynamic driver mostly the Performer 5+2, Truthear Hexa, and a Kiwi Ear Cadenza. To be frank these are the only IEMs I have left that I didn't give away or sell for cheap with Dynamic Driver drivers. And the only reason I have the Cadenza is because my children also need IEMs so it was a perfect time to match my IEMs with some of my children so we would all match. It gave me a lot of perspective on how I feel about an IEM's drivers and what I want from an IEM. Turns out I am not a fan of DD in general and why I never really found a cheap IEM I enjoyed. I just don't enjoy the sub bass and bass that DD gives me, it moves air for me that it's uncomfortable to me. While it's not a problem at low volumes some songs just still cause problem for me. Which I use the Performer 5+2 at lower volumes which means none of the problems I have with the DD matters to me. In fact for super quiet listening I prefer the Performer 5+2, but anything above that I gravitate to my BA IEM. Actually after listening to these I just really wanted an all BA driver IEM for my end game, which I eventually landed on but haven't spend a lot of time on it yet. And honestly am happy and finished like 90% of my IEM journey for a long time. The rest is getting a planar IEM I want and portable DAC/AMP. Then time to move back to headphones for a bit. I know I'll be back to IEMs but just not for a little while.

# Listening on Youtube vs Lossless/High Quality MP3

So to get started because I did note MP3 I honestly can't tell the difference between high quality MP3 and Loseless, I can tell the difference between low quality MP3 and high quality MP3. But these IEMs was the first IEM that made me feel like I spent too much for just random songs on YouTube. Like for YouTube I felt I was just as happy on a cheaper IEM, while some songs sounded how I'd expect with these IEM, but some songs just to test I have downloaded vs the YouTube and could tell something was off. And if you want to listen to stuff on YouTube only or any streaming service that is low quality (honestly I don't have stuff like Spotify or Tidal so I don't know if they have like low quality setting or stuff). Youtube has just felt inconsistent and these IEM made it easier to tell that it's there. Honestly I haven't been around YouTube music enough to tell you since I mostly test a few songs on YouTube and then go to my downloaded stuff and when I do listen to stuff on YouTube it's usually something I don't have downloaded or I tested some stuff and left it on auto. But that leads to my next point that when I am not paying attention to the music and just put it in the background I also can't tell quality of music. And this made it painfully obvious with how much I have to spend on some IEMs that in some cases I think I would have been happier with a cheaper all BA IEM for cases of just working.

# Initial Impressions to Now

I really liked these and it felt like it's what I really was missing in an IEM but not quite there. Took a lot of tip rolling since I did get these used the original tips were missing but luckily you can buy them. The tips I actually love on different IEMs but not these as I ended up using the flex. A few months later I ended up still using the Flex and it's the IEM I keep coming back to between the Performer 5+2 and Cantor. These solve the problems I have with like the Performer 5+2 that aren't at a soft volume and once again that's due to the fact there is no DD. Though these have made me notice a few problems time to time in music and force me to go to a different IEM for a little bit which I'll explain in the review.

# Review

The Sound - The review is me using mostly the Kiwi Ear Flex but with the Tangzu Sancai balance bore it doesn't change how I feel about the sound much. Bass I enjoy the bass of a BA over DD, it does give me a feeling when it hits it but it's not such a rumble feeling that I get with a DD even at louder volumes. Though it's a little more then I like but I love how it tapers off the sub-bass a little bit so it doesn't feel punchy. There does not seem to be any bleeding. And for a BA IEM it's pretty bassy and handles the bass quiet well. In fact just compare to the Cantor (which I still need to do more testing with upon writing this review) if you want an all BA IEM and want bass this is pretty great. Handles bass very well and controlled but without the punch that DD can do. The mid don't give me too depressed sounds like V-shaped IEMs do for me. It does a solid job of making sure the mids still come out well like a V-shaped flagship IEM should. The treble is like a knife that is perfectly sharp enough to cut what it needs to do but not so sharp it's not going to cause a problem. When you give and IEM and call it a flagship this is an IEM that hits all the point an all BA flagship should hit. But it does it in a way that it's very WOWing. It's not an IEM that if you spend a few hours with won't WOW you but overall is a good experience and something you expect to come from 400 dollars. It does the job and does it well.

The one thing I haven't talked about in this review or any other review is sound stage. With the the past IEMs I used for a time and sure some IEM has better sound stage then the others but it still feel likes it's still cramped in. Like you are looking at a mirror and it says like "Objects in mirror are closer than they appear" and all IEMs I've tried for more then a day feels like that to me. The Nezha does sound stage so well that it's a blessing and a curse. The sound stage is very well done and spread out well, when a song is mixed well with the channel it's a blessing, but when it's kind of bad, it sounds like one side hears better then the other and you notice it. Like listening to some orchestral tracks you can tell the sections apart and it sounds really good. But then you hear another song then they put the main guitar on the right ear and the back up on the left and the main guitar is very loud it just sounds like you have a hearing issue where one side just hears better then the other. Just kind of wish there was better way to mono music. Windows has it but it makes music sound like music with distortion.

Accessories - It's just so good it's got everything you need and wanted and expect from a flag ship. It's case is one of the best I've had and would buy more of these cases if I needed more. The cable is very solid and good and can change between 3.5mm and 4.4mm with it's interchangeable tips. The only thing I wish it would have done is given us a better cable color. A lot of this IEM shows it's a flagship.

Others - Another thing is Tangzu did an amazing job to make this feel like it fits well. It's not uncomfortable and I can wear it for a long time. Because of it's BA nature and what I think are pressure relieving holes I don't feel any of that being a problem and can wear these for hours.

# Conclusion

Thoughts - So this IEM is great the problem with this IEM nothing about it has a wow factor, it's just a solid and good BA+EST IEM. Nothing about it stands out. For 400 dollars not on sale I feel like this is too much. Not because it's bad but because it has other competition out there and it needs to stand out. It does everything that a 400 dollar IEM needs to do with sound stage and comfort being it's strong point. When IEMs get better and for cheaper or you can find something with a more wow factor at a higher point it's kind of too much. Around 300 dollars I say these start to become competitive and a talking point and a heavy recommendation. If you can find these used or are willing get these on sale (as of July 4th 2026 you can from Tangzu for 340 which I think is a little pricy but not bad) I think it's worth it. With something like the Orchestra Lite and Orchestra 2 around at it's price point of 250 and 350 it's got a lot to fight for. I don't have either one of those so I can't make a fair comparison with only 30 minutes with them. And with used Aful Cantors you can get at like 450 used or less (just based on Reddit's AVexchange with the latest going under 400 which might be a one time thing on Reddit) it has a lot to compete with.

I think these would be for gaming but I don't play games that require sound stage and the ability to locate the enemy on sound. Most I need it to do is sound good and me able to recognize things by sound queues. There no song it doesn't do well in, unless it's something you really want a lot of sub-bass or it's just poorly mixed. But I think you kind of know that if getting an IEM that doesn't have DDs in it. But it does have more bass then the Cantor for a fact which means more then the Orchestras.

Recommend - I do recommend these at lower 300 or lower easily, at 350 there is a lot of competition that I can say maybe for. No real major problem with the IEM it self but when music has channeling problem you can really tell.

Tangzu Nezha - Does this IEM sound good as it looks?
