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

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.

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.

I’m incredibly picky when it comes to sound - these IEMs sound amazing with a good quality 3.5mm to USBC DAC ($15 add on) on my iPhone. I’m hearing details in songs that are completely lost on Bluetooth headsets due to compression. They’re super comfortable, high quality and beat any Bluetooth headset. I wore them on my flight today and they actually cancel out the noise even though they’re not ANC. I have a high end ANC I always wear on flights but did not feel the need to use them. I’m using an XLR converter/amp to connect them to my bass amp / pre amp and they sound amazing! Non regret purchase.

Size: 3.5 of 5. Very bulky compared to other IEM. Fit: 3.5 of 5. The provided ear tips work but may not be the right fit for everyone. With a good fit, most external noises are suppressed/blocked. I think a primary issue comes from the spout size as it is larger than many IEMs on the market and could result in feeling pressure/fatigue from its excess size. Audio 4/5: Clear, clean. The quality of recording is distinguishable. If a track is high quality, it will sound like it. If the quality of recording has other noises (background, hisses, etc), it may be more noticeable. Cellphone Audio with JM6 Pro: Audio sounds good. I don't notice much difference when compared to Akoustyx R-120 (used with USB-C audio cable, no adapter). Comparison: When compared to Audio-Technica ATH-M40X and Sennheiser HD 6XX, using a Schiit DAC and Amplifier, Blue2 (w/o JM6 Pro) sounds recessed and not as pronounced/clear. There is a price difference between all of these, with Blue2 on the lower end. It's not 1:1 comparison between this line up; however, I hope you find this useful.

I want to start off by saying that overall the iems deserve a 5 star in itself. The cable is nice and sturdy, it's lightweight, and has a very universal sound profile. Great for listening to music, watching movies and gaming. Truly worth the value. BUT! I am personally not a fan of the included eartips. I don't really like the foam tips since they can deteriorate and eventually leave foam particles in your ear canal and that's a nono. The included rubber eartips are too "grippy" and are painful for me personally. If I had to describe it, i'd say it makes my ear feel like it's being burned/irritated. very unpleasant but it's an easy fix! I swapped the tips with much softer and smoother "rubber" tips from my 11 year old sony earbuds and now they are much better. If you're considering these i'd definitely reccomend a different set of ear tips. Over all like i said a very well deserved 5 stars. And with the eartip dilemma having a solution, no reason to deduct any stars. Buy them with a set of tips, you won't be disappointed.

Very good sound, extremely happy with its comfort and quality, I use this everyday for work/gaming and I'm in love. Make sure to get a DAC for it, as without it the sound quality drops by a LOT if you dare to plug it directly to your MOBO. This is a personal gripe due to the way my current setup is done right now, but I wish the cable was just a tab bit longer, other than that is just... PERFECT.

Considering the price bracket, these offer sound quality and listening experience way above what I was expecting.

Um excelente fone. Bem confortável para sessões longas

sounds good (u really should watch audiophile yt videos instead of comments here since we arent good at reviewing products)

Let's start by saying that I’m not really a huge audiophile, so take my opinion with a grain of salt. That said, I do tend to lean toward products that Crinacle has had a hand in tuning. To my ears, these sound really good. I’m not treble-sensitive, in fact, I actually prefer a bit of extra treble in the tuning. I’m using the FiiO K2 as my DAC/AMP on a Windows 11 PC (system volume set between 30–40%), and I adjust the volume within applications like YouTube Music, Spotify, and my browser. I’m using the included silicone ear tips and haven’t tried the foam ones yet. But since treble isn’t an issue for me, the silicone tips will likely be my daily drivers. I did try these on my android phone and on an Iphone, I'd say result is pretty much the same as using it for PC. There’s not much to complain about, although a few songs do sound slightly distorted at certain volume levels. Well, “distorted” might not be the right word, it’s more like there’s a peak in certain frequencies that lasts a few seconds in few songs (like metro booming music is a good example, or some lesser known artist or self published artist). I noticed this on YouTube Music, but when I tried the same songs on Spotify, there was no distortion, at least not when the volume was set to 80–90%. Some distortion did appear at 100%, but at that level, it’s kind of expected. It could be due to the song's mastering or the version uploaded to YouTube/Youtube Music. It doesn’t happen with all songs. Using the included bass adapter does help reduce the distortion, but not always. I believe it's the 2DD that's causing it, but I am a bit unsure about that, you do get used to it after a while, you kind of find it part of the listening experience, but it could just be me coping. Either way, it’s something worth noting if you’re considering these for music listening only. The additional bass adapter lowers the treble and boosts the bass (shocking, I know). Personally, I prefer the sound without the adapter when listening at lower volumes. But for daily use, I’ve mostly kept the adapter on. I do spice it up sometimes and listen to it without the adapter if I feel like having extra volume and umf to the music. These are also good for casual content consumption like YouTube, TV shows, movies and etc. I use them for gaming as well, wouldn't recommend them for competitive shooter games, you barely hear footsteps if that's important for you . They’re good enough for my gaming sessions (I play all sort of games, but I do switch over to my gaming headset if I am in a call or a group). I do, however, need to bump the system volume up to 50–60% for games. Edit: The only thing I really dislike is the cable, more specifically, the ear hooks. They don’t fit my ears very well. I’ve never really had this issue before with other IEMs, but with these, the fit is a bit loose and they occasionally fall out my ears. That’s mostly during the first 10-15 minutesm, after that, they settle in. But if I take them off and put them back on, I have to repeat the whole adjustment process dance all over again. Maybe I just need to give them more time to break in over a few days or weeks. Do I recommend these? I’m not sure. At full price, it's a tough sell. I bought them on sale and had a gift card lying around, so I figured, why not buy these at a heavy discount for me? But would I pay full price without any discounts or gift cards? Now that's a hard sell to say yes, I'd probably lean towards no if you have already good IEMs. Should these be your first? No. Should these be your secondary or third option IEMs? Maybe. At least then you can mix it up a bit. But my suggestion is if you can try these out somewhere, do so. Try and listen to your favorite songs with and without the adapter. If you can't try these out, try and look elsewhere instead if you find the full price hard to swallow.

Joya de audífonos si te gustan los graves o el bass. Importante tener en cuenta que por su impedancia pueden no tener tanto volumen en algunos dispositivos, sin embargo si los conectas a un buen DAC suenan de maravilla.
