Welcome to my latest look at IEMs. Today we start on fun journey. Welcome to:
Six For the Price of $20 or a Budget IEM Battle Royal
The idea of this started out with humble roots. I had the 7Hz Zero, had the CCA CRA for quite a while (until I lost an earpiece), and simply wanted to try out a couple of the other $20 sets I’ve heard things about. Then I grabbed more $20 sets that have come out recently, and before I knew it I was comparing six IEMs, more or less at once. Which I don’t recommend. Bouncing back and forth to different sound signatures has done a number on my ears. But that’s a me-problem. And I’m here to help you-problems: namely, which of these sets are worth it, when are they worth it, and even why you should pass on them. So, let’s get going on this journey with part one.
Songs to Listen to and Follow Along:
As usual, I’m going to write my thoughts in generalities, but I’ll give you a sample of songs that I listen to, that will relate to the concepts I write about. Feel free to ask for specifics, if you don’t keep up with my thought processes.
A Girl, a Boy, and a Graveyard - Jeremy Messersmith (for mids, male vocals and soundstage)
Poison - Slumberjack (feat. Sydnee Carter) (for mids, female vocals, some bass, layering and a soundstage check)
You Should Be Sad - Halsey (for bass, mids, female vocals)
Perception - Beard of Harmony (for guitars in bass and mids, male vocals, technicalities)
Traveling Upstream - Cody High (for pianos full register, technicalities)
Fire - Black Pumas (for technicalities including layering and timbre, soundstage)
One Potato, Two Potato, Three Potato, SIX!
So I think to start out, it’s the easiest to tell you what I listened to, and before I start with the comparisons (nee, nitpicking) lay out what general tier I find for each set. Because with these six sets, there are levels. First, though, introductions:
7Hz Zero
CCA CRA
CCA Lyra
Moondrop CHU
KBear Rosefinch
Blon Z200
Are You Sure You Go Here?
Next, I can fairly confidently trim this six to four. The BZ200 and Lyra and not bad IEMs. But I think both are a step behind the other four. The Lyra is a very competent neutral-warm type IEM. It’s got more bass and note weight than the Zero or the CHU and is only very mildly V-shaped compared to them. It has a pretty smooth upper-midrange as well, with a tasteful cut between 3-4k that counters the energy the Zero and CHU has. It’s a good complimentary sound to pair with either of those sets. The simple reason that Lyra isn’t worth grabbing is that the CRA exists. It’s cheaper and does the sound signature better than Lyra.
The CRA has a little bit more bass bump. In terms of degree, the Zero has just too little bass, Lyra has just enough bass, and CRA has just satisfying enough bass. Both CRA and Lyra slope the bass well and correct before going into the mids keeping bass bleed to a minimum, but the CRA is a little less recessed in the mids than Lyra. It’s a little more full bodied which I appreciate. That story continues into the upper-mids and treble. Lyra has a little bit more energy in the upper-mids and enough treble so I do not dislike it. But CRA brings just a little more control in the upper-mids and has just a touch more energy in the treble. CRA is a little better in the bass, a little weightier in the lower-mids, a little more controlled in the upper-mids, a little clearer in the treble, and it has a little bit better soundstage feeling more open and less intimate. All of this and CRA is a little cheaper too. All of these littles add up to make CRA just better than Lyra.
The Z200 is a completely average V-shaped IEM. I have zero complaints about the bass. It’s of quality on par with the Lyra and CRA. It has recessed lower-mids, upper-mids that start out with good energy but have an audible drop in energy going into the treble, and a treble that could stand a touch more energy than it gives. In terms of soundstage and technicalities, it does what it’s supposed to do as well. But that feels like the problem with Z200: It pretty much does everything it should do, and does it well enough. It is a good, average IEM at a very palatable price. The only thing with that is that in 2022, even the $20 price point is filled with a sea of monsters. A year ago, this IEM could’ve been a hyped up set. This year, it’s a set that has competition that are flat-out killers.
Now We Interrupt Our Regularly Scheduled Programming
If you can’t tell, I do believe the CRA, Zero, and CHU are a step above in this comparison, and I will get to my top-3 in time. But before I get there, I need to impress upon everyone reading this how much you should try out the KBear Rosefinch, if you fall into 2 specific use cases.
1). If you want a massive, unrestrained, “Boomy booty-booty buttcheeks” amount of bass, you NEED to try this IEM. The first time I listened to this set for a long session, I turned the volume up and the bass bumped so hard I started having a small headache afterwards. The amount of “too much” bass snuck up on me. This driver can absolutely thump! This tuning is definitely not for neutrality or accurate music reproduction. But the amount of bass, and the way the treble is tuned up to provide clarity, allows this IEM to be the best IEM I’ve heard at excessive bass levels. KBear goes for this in their cheaper IEMs, but this is easily their best implementation. If you like the KS1 or the Robin, this is an evolutionary jump compared to those. For $20 (and less if you can find it, I’ve gotten it for $12), this has the biggest quantity of bass of any set I’ve heard under $200.
2). If you are a believer in modding sets to get the best performance possible, you NEED to try this IEM. I’m a fan of Rosefinch in its stock configuration and felt no need to tinker because it’s a different flavor than what I usually listen to, and I liked it for that. I watched Akros’ review of Rosefinch and he lamented that KBear left a lot of potential on the plate, tuning it the way they did. He posited this is a VERY good driver, hidden behind a non-optimal tuning. In my opinion, Akros is correct!
I did a simple air-vent mod, and was shocked with what I heard. The bass became a lot more controlled and was of a quality on-par with sets like Tri x HBB Kai. The bass bleed was controlled, and the lower-mids were much cleaner (though now the recess wasn’t filled in with bass bleed. It’s still a net-gain). The shock was how much the soundstage and technicalities of the set opened up. Pulling the bass back and adding air (literally, in this case), while keeping the treble levels untouched to the ear, allows the driver to produce a massive upgrade in soundstage. It’s the best soundstage I’ve heard in a sub-$100 DD, outside of Olina. The composite biological driver this uses is class. It can make BIG sound, and it can make technical sound. I needed to know if you could marry the two versions into something special, so I taped the front vent and added that to the air vent. This put most of the sub-bass back into the sound, but kept the mid-bass reduction that tightened up the overall response. This is the best version of what Rosefinch brings to the table. The bass is big but completely under control. The mids have a good body, even though still a notable V-shape, and you retain the technical gains that the air vent put into the set. I even bought a second Rosefinch, to have the stock bass tuning because I do NOT want to touch my modded Rosefinch and mess up the tuning. And since I got them for $12 each, I’m still under $25 for the pair.
The reason I am putting this aside in its own tier, rather than making more direct comparisons to the other three sets left, is because those other sets have objective things I can point to in their favor for what they do better than the others. If I had only heard Rosefinch in stock form, I’d be able to do the same because this would be the default Basshead option I would recommend if someone didn’t want to spend hundreds of dollars.
I cannot be that objective about Rosefinch anymore, because IMO this is a unicorn set. I’m not insane to say this is better than something like Olina or Kai, Starsea, or those other sets I have high regard for. It is not better. But this driver, if implemented in a better way with a better tuning, could absolutely compete with anything you throw at it. Part of my musical search is about finding the right sound signature that will appeal to me. Another part is about finding driver technology that does something different with the music I listen to.
A driver is a driver, is a driver…until it isn’t. At the $100 and under bracket, Olina has a driver that is more than other drivers. We can quibble about the tuning but nobody has listened to Olina and said it sucks. If you believe in modding, you owe it to yourself to try this driver out and see if it sucks. Because I promise you, it does not. It is a crime that KBear put this driver in a $20 set. I don’t know if this is just a test-drive, and they’re going to use this driver in a better IEM, or it’s a one-off. But this set is a wolf in sheep’s clothing: this driver is the best driver I’ve heard that isn’t Olina, under $100. And while I don’t have the breadth of experience, I can’t imagine there is a better driver anywhere near how much Rosefinch costs.
What Does All This Mean (so far)?
I feel very strongly about the merits of Rosefinch, but if you are not in these two particular use cases, I don’t think you will like this set the way I do. Hence, it sits in a space all its own. KBear Rosefinch is a special IEM that I don’t know what to tell you to do with. But I encourage everybody to try it and see where you fall.
Next time, we will get to what you actually paid to see (wait, what…?): CCA CRA vs. Moondrop CHU vs. 7Hz Zero. Which $20 set is my number one of all? That’s going to be it for this review. Enjoy your days, and take care till part two!
