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!

The Zero:BLUE2 is a solid follow-up that mostly delivers on its promise of high-fidelity sound in a budget-friendly package. Tuning is clearly Crinacle-inspired—neutral with a slight emphasis on clarity, and it works really well across genres. Pros: Balanced tuning with excellent clarity and separation, especially in the mids and treble. The dual dynamic drivers provide nice layering and avoid muddiness, even in complex tracks. Detachable cable is a huge plus at this price point—easy to upgrade or replace. Build quality is great for the price, and the design looks sleek without being over-the-top. Cons: Bass is tight and controlled, but lacks a bit of sub-bass extension—bassheads might find it a bit too polite. Fit might be hit-or-miss depending on your ears. I had to experiment with tips to get a proper seal. Cable is decent but nothing special—definitely swappable if you're picky. Another slight nitpick is that at night the blue design looks black. Overall, this is a great set for anyone who values tonal balance and detail. It punches well above its price class, especially for critical listening. A few minor gripes hold it back from a perfect score, but it's a no-brainer recommendation in its range.

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.

Honestly these things are so crispy its insane. Ordered 2 but only because my cat licked and tried to eat the left ear so that doesn't work anymore. Can't really ask them to make these orange cat proof because that may be impossible. Sound quality is seriously good. I hear everything in the games I play, mainly Tarkov. Multiple rubber and foam tips so you can find a good fit. No microphone on the pair I ordered but thats fine. TLDR: these are amazing and worth the money, just keep them away from your cat/animal so you only need to buy them once.

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.

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.
