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

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.

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!

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’ve had over ear gaming headphones my entire gaming life - almost 15 years. 10 of those years, I’ve had Astro a40 TR headphones. I bought these on a whim after doing some research on IEMs and I don’t think I’ll ever go back to over ear. My poor astros are collecting dust! The build quality is great! With the memory foam tips, the noise cancellation is actually really good, my wife thinks it’s too good haha. The cord has held up nicely, although I make sure I don’t tangle it as I put them on and take them off every day. They give you many different ear tip sizes which worked great for me because my ears use two different sizes. I do wish the cord was a little longer but that’s not the end of the world. The audio quality is superb and I do use the resistor to give the audio a little more bass.

Excelentes bajos , muy limpios , el paquete muy completo

Excellent product with clear a clear audio expeirence. Somewhat pricy with it being around 100 dollars, it still held up after months of constant use. It came at the expected delivery date and serves as a fantastic alternative to the usual headphones. Highly recommend.

Um excelente fone. Bem confortável para sessões longas

期待はずれ

Definirle ottime è riduttivo, la qualità del suono e il bilanciamento tra alti e bassi è veramente eccezionale, in più con il cavo con microfono vanno benissimo anche per le chiamate, così da avere un unico paio di cuffie per tutte le esigenze. Con altre cuffie di questo tipo ho riscontrato un fastidiosissimo fruscio che sentivo solo io durante le chiamate, con queste tutto è veramente cristallino. Anche la dotazione di gommini è molto buona, ci suono sia quelli in silicone che quelli in foam, quindi adatte a tutti gli usi e a tutte le orecchie. Consigliatissime
