That color-alterating resin is always wonderful to look at, and the shells are overall quite light, with a slightly recessed 2-pin connector that might be polarizing, depending on opinion. My Chus are connector modded so that I can use them with my AZ09s when I'm out of at work, so I wasn't super happy to have to trim away at the protective bits of them to mount the Zeros.

In terms of bass quality, the RED’s low end is among the best you can get in a neutral DD IEM before getting up to the more expensive and exotic stuff. It would have made writing this review so much easier – “cocky IEM maven designs cheap IEMs, and they SUCK!

Also, this leads to a strange hollowness in the mid-bass region, something “mid-bass bad” crowd will probably try to pass off as a positive, but it is not often the case. This latest incarnation is tuned to Crinacle’s own IEM target curve and has an upgraded crossover, reportedly to improve distortion performance. On the other hand, the lower treble has a good deal of energy, which keeps the response clear and pristine just like the upper treble.

If an item weighs more than 9 pounds, we won’t be able to ship to these addresses because of our current courier agreements. Quite often you will also find Hi-Fi equipment offering direct connectivity to devices with Android and iOS to simplify the connectivity process. Compared to the OG Zero, where the lower vocal notes have more density and warmth, the midrange has a more accurate tonality. The Truthear ZERO offers a smooth, soft and detailed sound thanks to the mature internal magnetic circuit structure co-worked with a flexible polyurethane suspension composite LCP liquid crystal dome diaphragm.

for reference, I prefer the tuning of the Tangzu Wan'er and the Moondrop Chu II (since I mostly daily drive the two) because of the detail, Imaging, and sound separation. I started with the Large ear-tips with small cavity (I like my bass) but it was boomy and unbearable. If you feel that Harman IE is a thing you wanna try out, I think this is one of the few sets in the range that does that reliably, given my reservations to this target. It is a business with talented designers and engineers who have produced audiophile-grade products that are well-liked among audiophiles. While its smaller staging could be improved, I don’t think it detracts too much from the sound and its coherency and articulation more than makes up the difference.
