Two sets of white S/M/L silicon tips for 6 pairs in total. Each set has a different bore size which will give a slightly different treble response. I used the medium size tips with narrow bores for this review. The RED retains the same 7.8 mm and 10 mm dual dynamic driver configuration of the Zero where the 10 mm acts as a subwoofer with a crossover at around 160 - 180 Hz. But beyond a simple re-tune, extensive work was done to modify the driver’s voice coils and revamp the crossover circuits for better performance. Furthermore, there’s an included 10 Ohm impedance adapter to further increase the bass response by leveraging the RED’s electrical impedance curve. Build in general is good price considered. Its made of good quality plastic, feels ok in the hands. Faceplate is a change from previous zero, this time its red like the name. Shells are average to small size. They are light weight. Fit is good, quite comfortable even for long listening sessions. Fit stability is good as well. Fit breathability is average. This has a fat nozzle so proper fit might be a bit subjective to ear size. Score 3.75/5 But I don’t love it. I appreciate it. Though it’s a great listen and there’s little to find fault in its sound, the RED doesn’t enamour me the way Crinacle’s previous collabs like the Moondrop Blessing 2: Dusk and Fearless Dawn did. To use a horrible cliche, the tuning of the RED is like a pair of studio monitors. Not that it sounds like one, but rather that the RED is accurate and timbrally correct in a way that is hard to argue against. But like studio speakers, there’s a reason why the stereo hi-fi industry exists: not everyone wants that. With ZERO: RED, mids are again relatively neutral, so there’s little else to write home about. There’s not enough resolution to imbue them with the magic that higher-end IEMs often offer.

Hi guys, I'm new to iems and I want to switch to them from headphones because earbuds are more comfortable to me than headphones for longer periods of time. I was wondering which of the two would be better for me, since they both fit into my budget and I've seen both be recommended for gaming. I mainly play fps games like Valorant, CSGO, and sometimes R6 and Apex, so things like footsteps and clear directional sound or a "wide area"/"field"? type of audio where I can clearly tell where enemies are, are pretty important for my decision.I do feel slightly miffed at the recessed connectors on the IEMs, because it meant reduced compatability with other two-pin connectors. 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. The acrilic stand also had some scratches and scuffs on it out of the box, but these were relatively minor and I don't know if you can even see them in the picture. When these qualities are combined with its monitor-like tuning, the RED’s overall presentation is unique among the IEM market. The RED’s textured bass and tightly controlled treble response elevates its sound beyond seemingly similar IEMs. 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. I’ve heard a lot of budget IEMs. Most are me-too products in the race to the bottom with the usual trade-offs in tuning against its peers. The RED is not one of them. Newcomer’s Note: This article is written towards those who have been in the hobby for a while and will feature discussions of frequency response graphs and measurements. If you’re unfamiliar with them, here is a great primer from Resolve on what those graphs are and how to interpret them.

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.

The Truthear Zero is an in-ear monitor (IEM) which uses a dual dynamic driver setup. There is a substantial elevation in the sub-bass which is contained entirely below 200 Hz." Staging is average, imaging is mostly left and right. Not a technical tour-de-force in those regards. Layering is surprisingly good though, probably one of the strengths here. Overall resolution is middling. music because this is where you get a lot of buildup with guitars, vocals, and even the top-end of the bass guitar At the end of the frequency spectrum, we get to the Air region or the Top End. This region consists of everythingThe included cable is fine. It has four separate conductors, so a retermination to balanced is doable. It is a bit prone to tangling but doesn’t hold kinks and bends for a long time. The cable works fine and keeps out of the way of the listening experience. Comfort

Like the original Truthear ZERO, the ZERO: RED uses a 10mm dynamic driver for low frequencies and a smaller 7.8mm dynamic driver for the rest.

Their previous work was the Truthear ZERO which, like the RED, used a duo of dynamic drivers and was tuned to the Harman IEM target.
