TRUTHEAR x Crinacle Zero:BLUE2 Dual Dynamic Drivers iEM Headphone with Detachable Cable (3.5mm)

The TRUTHEAR x Crinacle Zero: BLUE2 has been an outstanding upgrade to my audio setup. The sound quality is excellent right out of the box, offering great detail, clarity, and separation that makes them fantastic for both gaming and listening to music. One thing I immediately noticed is how comfortable they are. Even during long listening or gaming sessions, they remain comfortable without causing fatigue, which is something I really appreciate when using them for hours at a time. Another major improvement is the included cable. It feels incredibly premium compared to the cables that come with many other IEMs. It’s soft, flexible, well-built, and doesn’t tangle easily, making the overall experience feel much more refined. While they already sound great on their own, they truly shine when paired with a quality DAC. The extra power and cleaner signal noticeably improve the overall sound, bringing out even more detail, better separation, and a more immersive listening experience. Overall, these are excellent IEMs that deliver incredible value. Between the comfort, premium cable, and exceptional sound quality—especially when used with a DAC—they’re an easy recommendation for anyone looking to upgrade their audio experience.

Great IEMs for a reasonable price The casing seems to be plastic but feel strong enough to not break easily. The sound is a little thin unless you use the included +5 ohm adapter, but still sounds respectable without. The ear loops are a bit big if you have smaller ears, but are still pretty comfortable even wearing my glasses. They also come with 3 sets of foam eartips and 3 sets of silicone eartips all in different sizes to make sure they will fit in any ear. They work on any device that has a 3.5mm aux port only as there is no included adapter to 1/4 inch. As the name implies the only color is Blue and the device is not waterproof, it is however water and sweat resistant as long as in ears.

TL;DR, it does what it says on the tin, although I had to get one that was defective and return it and get a second one in order to get that. The first one of these that I ordered the right driver whenever you would tap it or pull on the cord a little bit or even speak while it was in, it made a loud resonant doiiiing sound that seemed like maybe some part of the internal components was not properly attached to the casing. Drivers sounded fine when playing music, but that's not what the product is supposed to do. Amazon really pushes you to contact the manufacturer first to see if they can help you. And it might have made sense for Truthear to just send me a single right driver from China, they wouldn't then have to deal with maybe taking a loss on the entire return product. I went to their website, sent in a message on their webform explaining, and they just never responded. It's been a week and I still haven't heard back from them. After a couple of days of no response, I just returned it via Amazon and got a second one. So the lack of a fifth star is not about the actual product itself, the second, good one that functions. But that Truthear sent out a damaged item for sale, and then just didn't even respond, seems like lack of reliability and responsibility here. In terms of fit, these are a little bit bulky, the actual driver housing. I bought these to replace my pre-Logitech Ultimate Years Triple Fi 10s that I bought for ~$330 in 2007 (and turned out to be a really great value because they made it all the way to 2026 before they finally failed; it was the external casing that actually failed, not the internals). The Triple Fis come out from your ear more, and all it makes you look like Frankenstein a little bit, it does prevent contact with your ear. These are more flat in towards your ear, and it feels almost like a larger volume overall, but they're mostly fine; it all fits in the ear cavity. If I wrap the cord behind my head, it does pull the driver just a little bit into my ear in a way that gets uncomfortable after an hour. I found if I run the cords in front and even pull it up underneath my chin, although that looks kind of goofy (like a string for a hat on a windy day), it is comfortable for multiple hours. On the not looking goofy side, I was a little concerned that the blue would be too shiny, but it's really quite subtle (black-like) unless it's in direct bright light. One of the reasons that I bought this version (and not the original blue or the red) is that this has a narrower nozzle that you can put normal tips on. I actually used my same ultimate ear tips with these and they fit on fine and actually work better for my ears than any of the tips that came with. That's not really a criticism of the zero blue2 that the tips aren't ideal. It's more positive that you can put whatever you want on it'cause it's got a more standard nozzle size. The un-EQ'd sound is what it's supposed to be. It's pretty flat, but with a little bass boost. With most other headphones or IEMs that I use, I am using Wavelet on Android to make them Harman normal first and then I make some tweaks from there, maybe adding some bass and often a little bit of high-end treble. With these it's so flat, I don't really feel like I need to run the auto EQ to get that baseline. I just make tweaks based upon what I'm listening to and what I want it to sound like. The dual drivers seems to do what it's supposed to do. I can turn up the sub-bass plus +8 db, and quite thunderous, but clear, and you can still have vocals on top of that that are themselves also perfectly clear. Also in general, vocals are extremely clear, especially if I ran an increase across 1-2000hz of plus three or four decibels to put them more stage-forward. I found myself listening to CHVRCHES songs and I could understand words that Lauren Mayberry was singing that I hadn't really noticed or hadn't been able to understand before because they're much more clear; and wanting to just go through other vocal-forward tracks because they sounded so good. That sort of clarity I think is the most obvious way that this IEM is clearly superior to the Triple Fi. I am using a Fiio BTR11 to drive these and it seems to do fine. "I will damage my hearing if I listen louder than that" is about at the BR11's 80% volume point. For $65, I'm not really sure what the point would be in spending more money than this. Durability and customer service, perhaps. Music sounds like I have the signal jacked directly into my head, which is what IEMs are for. And especially with always running EQ, I can make these sound like whatever I would want them to sound like. So it seems like they have all the capabilities I want. Hopefully they survive for 20 years like the TripleFis, although not sure I'm holding out a lot of hope for that, but again would be a good value even if they survive a fraction of that time.

I bought the TRUTHEAR x Crinacle Zero:BLUE2 IEMs to use in a very loud eSports arena while coaching my team at our State Championship, and they absolutely delivered. At first, I was a bit hesitant because the volume coming straight out of my PC’s motherboard 3.5mm jack was pretty low. The IEMs sounded clean, but not nearly loud enough for a noisy competition environment. The key discovery: these need a decent DAC to really shine. Once I paired them with a proper USB-C DAC, the difference was night and day. Volume, dynamics, and clarity all came alive. So if anyone thinks they’re too quiet, don’t blame the IEMs—add a quality DAC and thank me later. With the right source, these are phenomenal for FPS and competitive play. They isolate extremely well, making background noise in the lab and arena virtually disappear. Comms are crystal clear, positional audio is precise, and most importantly, footsteps are incredibly easy to pick out. The dual dynamic drivers provide clean lows without muddying the mids and highs, which is exactly what you want for tactical awareness. Build quality is solid, the detachable cable is a big plus, and comfort is great for long sessions. For anyone serious about competitive gaming, coaching, or eSports environments where clarity and isolation matter, these IEMs are an outstanding choice.

I've been daily driving these for quite some time, and I've only ever had issues with the foam earbuds getting dirty and needing to be replaced. Both the silicone and the foam earbuds fit perfectly well, but there's a small but noticeable drop in passive noise cancellation when switching to the silicone ones. The cord length isn't impressive by any means, but it gets the job done and can easily be replaced with something longer. The sound quality is great, and they work well for gaming as well as general music listening. They have a good bass depth and the included 10 Ohm adapter boosts it slightly. DO NOT PLUG STRAIGHT INTO MOTHERBOARD AUDIO! Get a USB C to Audio Jack dongle for these, it'll fit the intended Harman target much better, increasing audio quality. I've been taking these on the go from my home to university, and they are quite durable. It only few scratches on the IEM backing after quite a while of rigorous use. Overall, great IEMs!

Excellent comfort thanks to TruthEar and Crinacle thinning the nozzle. The included ear tips are great, the foam tips are recommended by Crinacle as they help keep the treble from being too bright compared to silicone tips. The fit is great, I find the included foam ear tips in small or medium sizes work best for me. The cord is a good length; it isn't too long or too short, just right for an IEM. The functionality is excellent, the IEMs sound great, and it's a huge improvement over the previous TruthEar Zero Blue. These Blue 2 have superior sound quality, better imaging, a larger soundstage, and most of all are still an excellent value. They cost far less than the Moondrop Blessing 3 but are about 85% as detailed. The build quality on the Blue 2 is excellent, far better than I expected given the incredible value and price point. I highly recommend the TRUTHEAR x Crinacle Zero BLUE 2.

The Audio is very quiet without any third party programs to boost the heck out of it. the earbuds have caused my ears to swell and are incredibly uncomfortable and do not fit well. The directional audio is actually pretty solid for earbuds, but you would get way more value out of actual headphones, even cheap ones.

Let's be realistic: if you are buying these for competitive gaming, you'll love them. The soundstage is wide, and the separation makes tracking footsteps easy. But if you're buying them to casually listen to rock or pop music, they lack fullness. They are incredibly easy to power off a standard phone dongle, which is nice. However, the plastic shells feel a bit hollow, and the overall tuning is just too intense in the upper mid-range. It’s a solid $65 IEM

Yes

As someone that almost religiously plays video games (all types but mainly shooters) these are a hugeeeee upgrade from a "gaming headset." Having used the Logitech G Pro x's for a long time the Blue 2s just blew them out the water. If you're fortunate enough to have a standalone mic or can afford one, theses are a worth while purchase and I would definitely recommend tying. To start with, they did hurt my ears but after trying the different types of buds they come with and my ears getting use to them I can comfortably game for multiple hours with any issues.

Great sound and quality
