Sound quality description
In this review, I use the standard eartips size L and drive it with the FiiO M15.
The FZ Liberty Z2 has a neutral-conscious V-shaped sound signature.
Please see here for detailed reviews on sound quality.
Lows / Bass
The bass of the FZ Liberty Z2 is somewhat expansive in the lower midrange.
The bass drum sound is quite thick and massive, but it is shallow-bottomed and lacks rumble and is lacking in realism.
The electric bass has a darker sound, but lacks tightness. It has a warm, dusty warmth and a live feel, but it lacks in depth.
The Liberty Z2's volume is enough to satisfy bass lovers, but it falls a bit short in depth.
In terms of balance, the presence tends to be larger than the midrange, and the midrange tends to be a bit muddy.
The midrange of the FZ Liberty Z2 is slightly concave in the center, emphasizing staging.
The midrange is fairly linearly tuned, giving it a V-shape, but the angle is relatively gentle and not too unnatural in its overall impression.
Female vocals are heard to lean forward slightly, and the guitar edge also has the sense of popping out a bit from the back, which gives the impression of emphasized three-dimensionality.
The midrange has more depth and also seems a bit wider on the left and right sides. Because of this, the texture is a bit imprecise and lacks freshness, and there is a sense of stagnation of resonance in the center of the midrange, giving a slightly out-of-focus and cloudy feeling, and coloration tends to be a bit poor as well. However, the transparency is quite high and the resolution is very good, so even with this cloudiness, a high degree of clarity can still be obtained.
In terms of sound balance, this is clearly not for audiophiles who are faithful to the original sound, but thanks to its very good resolution, it is rather rewarding to listen to.
Highs / Treble
High frequencies are a little less energetic, and luminance is a little lacking. As a result, definition is a bit weak, subtlety is a bit lacking, and detail tends to be a bit fuzzy. Extensibility is a bit lacking.
Sibilances, for example, are a bit weak and sting is suppressed, making this a safe choice for those who are sensitive to high frequencies.
High frequency resolution is so high that cymbal crashes are not exhilarating and hi-hats are not well colored and grainy, yet their presence is clearly felt. The weak presence of the highs on the sound balance is compensated for by making the highs heard clearly with the highest resolution.
However, although the highs are heard well with high resolution, the sound balance is a bit poor, so the vertical axis of each instrument seems to be undefined, making the sense of localization difficult to discern.
Sound quality general comment
- Original Sound Fidelity: A-
- Recommendation: A-
- Personal preference: A+
The FZ Liberty Z2 has an incredibly low distortion and high resolution sound for its price. The sound balance is not very good, especially in the midrange, and it is not audiophile-friendly, but its rare high resolution makes its sound uniquely compelling.
The sense of localization is not good, the midrange is veiled, the low frequencies lack depth, and the overall sound is cloudy and hazy, but the sound is lively, richly resonant, and immersive.
The unique musical space where one can immerse oneself in the music as if enjoying a daydream, though clearly habitual, has reached a unique state of being and strongly fascinates me. I would recommend this gem for those who want to immerse themselves in music and listen to it without thinking about anything. It is a comfortable music space with beautiful bokeh like enjoying music with old lenses.
I recently listened to the KZ Ling Long, which is near the best ever in KZ history, neutral, with excellent frequency response but low resolution. Frequency response and resolution. It is probably a difficult question for audio manufacturers to decide which is more important in the end, but personally, I found the FZ Liberty Z2 to be considerably more rewarding to listen to than the Ling Long.
Sound quality features

The FZ Liberty Z2 IEMs create an enveloping acoustic space that is as high-resolution, clear, and low-distortion as ultra high-end, yet so richly resonant that the music is veiled and vaguely dimly audible. Because of their clearly idiosyncratic sound, these earphones are not suitable for audiophiles who are faithful to the original sound. However, the unique worldview that allows you to enjoy music like a daydream while awake cannot be experienced with other earphones.
