CCZ Harmony BC01 Pro detailed review: A fusion of vibrant bass and clear treble
The package contents are simple, including the earphones, CCZ's patented bass-boosting eartips (S/M/L), a cable, and instructions. Of particular note are the patented earfins on the back of the earphones.
This provides a comfortable fit and it is designed to be comfortable even when used for long periods of time.
It has a hybrid configuration of 1DD+1BA. The faceplate is a combination of zinc alloy and clear panel, reminiscent of KZ's AS24, AS16 Pro, and AS16 Pro X.
The re-cable terminal is TFZ 2PIN, but any standard 2PIN can also be used.
The back of the main unit is equipped with CCZ's patented earfins.
This is a device to improve the fit, and for those who fit it, it will be comfortable even when used for a long time. These earfins are not simply hooked on the ears, but to achieve a stable fit by fitting to the shape of the ear.
You can feel its sound characteristics by directly using it.
Low-frequency range: The bass is characterized by its strong projection. The volume itself is not excessive, but it resonates powerfully. However, the sound is not muddy and the separation of the bass is good. It has a unique sound that is suitable for dance music, like KENWOOD's 3-way speakers and floor speakers. The lingering boom is particularly emphasized, giving the music a sense of power and groove.
Bass quality: The bass is not overly emphasized, and the separation of the sounds is well-maintained. The bass is powerful, but it doesn't interfere with other ranges, and it delivers a clear sound.
Treble: It has a slightly metallic impression, and you can tell that the BA driver is doing its job well. It is clear and well-balanced, adding a touch of glamour to music.
About the quality of the treble: The treble has a slightly metallic impression, and you can feel the BA doing its job. This suggests that the treble has a clear and sharp sound quality. Balanced armature drivers are generally considered to be excellent at reproducing treble sounds, and this characteristic is utilized in these earphones. The "metallic impression" means that the treble has a hard, brilliant sound.
Mids: When listening to songs like "ENTERTAINMENT" by Mili, the female vocals seem to be a little low-pitched and bass-heavy. This is likely due to the strong bass presence. However, the vocals are never drowned out.
Overall sound balance: The CCZ DC/BC series gives the impression of creating a sound based on the bass of CoffeeBean. The "CCZ Melody," which is thought to be the basis of Harmony, also appeared in the CoffeeBean era as a model that improved the clarity of the high range, and this unit can be said to be a replacement model.
Regarding sound resolution: "The sound resolution is quite good, but it's just average, and not particularly surprising for the price range (among Chinese earphones)."
The sound resolution (the ability to express the fine details of the sound) is commensurate with the price, and is not particularly outstanding. However, compared to Chinese earphones in the same price range, it can be said to be at a comparable level.
Impressions of specific songs: When listening to Mili's "ENTERTAINMENT," the impression was that "the female vocals are a little heavy and lean towards the lower range." This means that the female vocals sound a little low-pitched.
This is probably due to the strong presence of the bass, but it doesn't seem to be so strong that the vocals are buried.
In addition, it is said that "the sound of the timpani may feel a little closer and emphasized," suggesting that the sound of certain instruments tends to be emphasized.
Compatibility with metal music: "The metallic feel and clarity of the high range is a good match for metal music that includes guitar riffs, and the strong bass (even the high range of the bass) makes it a good match."
The clarity of the high range and the power of the low range make it a good match for metal music. In particular, the expressiveness of the guitar riffs and the emphasis on the higher range of the bass add power and depth to the music.
CCZ has gained a name for itself in the past with its Coffee Bean earphones, which have been particularly well-received.
The Coffee Bean has been well-received by many users, especially for the quality and quantity of bass. Since then, CCZ has released several high-priced earphones other than the Coffee Bean, but unfortunately they have not achieved the same success as the Coffee Bean.
The impression I get is that the recent CCZ DC/BC series earphones, including the CCZ Harmony BC01 Pro, which is the subject of this review, are based on the bass of the Coffee Bean. In other words, CCZ is trying to update and reinterpret the sound of the Coffee Bean, which was a successful experience in the past, with modern technology.
Specifically, the Coffee Bean was characterized by a warm, voluminous bass sound, but the high range was somewhat subdued. In contrast, the Harmony inherits the good bass sound of the Coffee Bean while extending the high range and creating a sense of openness, aiming for a more balanced sound.
Another earphone called Melody was also released during the Coffee Bean era as an earphone with a more extended high range and a more open feel than the Coffee Bean, so it's a replacement for the Melody.
The BC01 Pro Harmony can be said to be a modern version that has been refined from past models such as Melody and Coffee Bean.
In other words, CCZ is valuing the bass know-how it has cultivated with Coffee Bean, while improving the treble range to meet the needs of the times, aiming to produce a sound that can be used in a wider range of music genres.
The BC01 Pro Harmony is one result that shows this evolutionary process.
CCZ has had success in the past with their bass-heavy earphones called the Coffee Bean.
In recent years, the DC/BC series has been designed based on the bass tones of Coffee Bean.
The Melody is a derivative of the Coffee Bean with improved high frequencies, while the BC01 Pro Harmony is an evolution of the Melody.
While inheriting the good qualities of Coffee Bean, CCZ aims to achieve a more balanced sound through improvements to the high range.
With this background in mind, you can gain a deeper understanding of the intention behind the development of the BC01 Pro Harmony and the type of sound it is aiming for.
Generally, it works well with pop music and EDM. It is particularly appealing in dance music and electronic music, where the resonance of the bass is important.
There is nothing unnatural about the sense of positioning, so classical music can be listened to, but there is a tendency for low-pitched instruments such as timpani to be slightly emphasized.
The metallic feel and clarity of the high range also works well with metal music that includes guitar riffs. In particular, the high range of bass is emphasized, giving the music power and depth.
The BC01 Pro Harmony is especially recommended for those who want to enjoy the expression of bass.
Unlike the KZ Castor, which pursues the volume of bass to the limit, these earphones maintain a balanced sound while still allowing you to enjoy a distinctive bass sound.
They are ideal for those who want a floor-like bass sound reminiscent of the dance scene, like the KENWOOD three-way speakers.
The CCZ Harmony BC01 Pro is a unique hybrid earphone that combines clear highs and dynamic lows.
It is particularly notable for its bass expression, giving music a sense of groove and power. It is especially recommended for those who like pop, EDM, metal, and other music. It is also reasonably priced, making it a great value for money.
