Truthear x Crinacle Zero review

The Truthear X Crinacle Zero is an IEM (in-ear monitor) that uses a dual driver setup.

What does this mean?

In-ear monitors are devices similar to earbuds, used by musicians, audiophiles, or audio engineers to listen to music/create music. The fundamental difference between the two devices is that with IEMs, you insert them into the ear canal, whereas with earbuds, they rest on the outer ear. IEMs typically offer great portability, noise cancellation, high sound quality, and comfort. You can customize them as well, you can replace the cable and change the eartips. Dual driver IEMs have two speakers (aka drivers), where one handles the bass frequencies while the other handles the mids/treble. This allows for a richer sound, which makes any type of music sound better.

Equipment used

I did all of my listening on a Pixel 4a. I didn't use an amp, and I used the stock cable that was included. The silicone eartips that were provided were what I used.


front The Zero is a very well packaged IEM for the price. The box has an anime bunny girl on the cover. While I'm apathetic towards this type of aesthetic, it undoubtedly has a place in the market since IEMs are vastly more popular in Asia, and in most Asian countries, using this type of art to advertise is normal. Whether you like it is up to you, but I wouldn't judge the product based on the presentation. On the back of the box, there is a frequency response graph and the usual specifications. freq I like the response graph since it allows for more transparency from the manufacturer. In the box, there are a few accessories provided:

accThese are pretty standard for $50 IEMs, however I'm not a fan of the pouch. It feels too small and doesn't provide any enough protection (or really any, if I'm being honest). The cable tangles easily and is a bit too thin for my liking, however, you can change it. cableI think Truthear packaged the IEMs in a very presentable manner and they come with a good amount of accessories.

Look and Feel

Truthear made the Zero of transparent resin and has a triangular design. The faceplate is a swirl of purple and blue sparkles. Depending on the angle of where light is shining on it, it can alternate between the two colors. It comes with a larger sized shell, but the Zero felt comfortable in my ears and I had no issues with the fit. The fit is subjective to who is wearing them, so take it with a grain of salt.

The sound

The Zero targets the Harman curve. This is a tuning that is based on a study conducted using blind listening tests to find the most natural sound signature. It's a common tuning, and it usually emphasizes bass/mids.


The bass is the best part about the Zero. The low-frequency sounds sound full, and there is a lot of rumble and slam. I'm not the biggest bass fan, but for the bass enjoyers out there, this IEM will sound wonderful to you. I listen to multiple types of genres so I'll use these for the bass heavy genres.


Vocals and instruments sound fine most of the time. However, in the upper mids, vocals sound harsh and can be unpleasant. I felt like some of the clarity in this range got overshadowed by the bass.


I felt like the Zero’s treble range was rather lackluster, similar to the mid-range. Instruments like cymbals, the violin, snare drums, lack detail and sound dull. This lack of detail makes the audio decay sound rough, and it is very noticeable on songs that lack heavy bass lines.


The Truthear X Crinacle Zero are very enjoyable to listen to! I think it's a fantastic IEM for only being $50, and the bass is comparable to very few at the price range. It's great for people who don't own IEMs. Give them a shot if you're interested in buying IEMs!
