If the music you’re listening to doesn’t have too much information in the lowest octaves (as with a lot of purely acoustic tracks), its impact won’t be heard too much. And today I'll be reviewing the Zero: Red Edition, but first let me clear up a few misunderstandings. I don’t think it has much to do with better electronic components rather than changing the frequency where the drivers cross over to each other. The vocals sound expansive in the upper treble, but the notes become drab and vague as the frequency increases.

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. It was secretly going around to trade shows to get feedback from people and underwent multiple revisions in the months since.

Even something more instrumentally-focused such as Battle Tapes kind of sucked listening to, which is a big shame. When these qualities are combined with its monitor-like tuning, the RED’s overall presentation is unique among the IEM market. Two things caught my attention - the fact that the Zero was tuned to the Harman IEM target, and the fact that the RED supposedly has a more recessed bass. As I came to the end of this review, I came to the conclusion that the Red deserves the attention of all audiophiles for its excellently established reproduction and effective exposure to the sound. This is most apparent in the midbass body of electric guitars - the textured tone of the amps are beautifully rendered…but only if it’s emphasized enough in the mix to be heard.

Truthear had a relationship with other established brands, including MOONDROP, and it's connection to the established distributor SHENZHENAUDIO also helped give it an edge from day one. Music is at the core of what we do; and it's our aim to help you rediscover your music and help you enjoy the riffs, basslines and solos that were always there, but never heard.Normally this alone would not be anything special given the multitude of new brands that seem to pop up every month from there but something was different this time. The Truthear ZERO also has a unique driver configuration and is here to impress you with its sonic characteristics! DRIVER SETUP​Truthear Zero uses two dynamic drivers in an asymmetric orientation: one near the nozzle (tweeter) and the woofer is closer to the center of the shell.

This is a purchased unit therefore, all of the concepts I've expressed below are entirely my own, original ideas that haven't been influenced by anyone else. COMFORT, ISOLATION, AND FIT​The Truthear Zero are very comfortable due to their pseudo-custom shape, and they offer good isolation.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.

That is not to say that the bass quality is flawless, however; I found the crossover point at ~170Hz to be noticeable in listens and an EQ point placed there resolved that tiny issue. The bass is absolutely the stand-out performer on the Zero, thanks to the dual dynamic driver setup, with one serving for sub-bass frequencies only. Let's find out in our review today as we begin with a look at the product specifications in the table below. 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.Regarding the bass, I think it has one of the best responses I've heard, sounding well-tuned with a strong mid-bass response and convincing sub-bass response, though I do wish the mid-bass had more warmth. Although the speed of resolvability is still commendable, the attack of notes is nicely timed but the decay of notes is not.
