KZ ZSN PRO 2
Package
The packaging is compact enough to fit in the palm of your hand.
The simple design makes the earphones stand out beautifully against the white background.
When you open the package cover, you'll find the earphones themselves.
The accessories are stored at the bottom, so take them all out and check them out.
Accessories
Set contents
1. Earpieces: Silicone type, S/M/L sizes
2. Cable: 5N OFC cable, 3.5mm 3-pole L plug, 0.78mm TFZ type connector
3. Instructions
Compared to models costing over 10,000 yen, the accessories are fewer, but as an entry model, it has the bare minimum, so even first-time earphone buyers can use it with confidence.
Earphones
Build
The cover has a beautiful design, with crystal cuts peeking through the zinc alloy frame and reflecting light like a jewel.
The shell is made of resin and has an average weight of 4.7g per side.
The metal nozzle has a standard size of 5.7 mm.
By creating a bulge at the end of the shell, the fit to the ear is greatly improved.
The excellent fit means that you won't feel any fatigue or pain even after using the earphones for long periods of time.
They also have excellent sound insulation, with almost no noticeable sound leakage.
Specifications
Driver
This is a hybrid type earphone with a 1DD+1BA configuration that combines a DD with a diaphragm with a 10mm PET surface treatment and a custom BA.

Acoustic Fidelity
Quality of different sound ranges *In the above Usage Environment
The sound is powerful yet soft.
The bass is heavy, rather than boomy.
Treble
The treble range is modest, giving a quiet impression.
The highs are not harsh, but they are not lacking, so the music does not become dark.
Midrange
There is a slight recession in the midrange at certain points.
When checking the frequency response, there is a valley around 700Hz to 800Hz, which is clearly visible in the sound.
As a result, the midrange feels a little muffled and the resolution is lacking.
This is in line with the price, and is the only weakness of the BC01 PRO.
However, from around 1000Hz, the performance of the BA driver is demonstrated.
Female vocals in particular resonate clearly without being hidden.
Bass
The bass range gives you the feeling of powerful pressure, as if it's being pushed by a surface.
They are characterized by a soft sound quality with a lingering sound, and also play a role in giving the midrange more thickness.
Both the mid-bass and sub-bass are powerful, producing a thumping, powerful bass sound.
They also follow the music closely and don't lag behind.
This rich bass range makes music more enjoyable.
Localization/Sound Field
There's no problem with localization, and the sound field is somewhat wide.
You can feel the breadth and depth to the left and right.
The genre of music they're good at is EDM and other programmed music, which is perfect for songs that emphasize bass.
On the other hand, I don't think they're very suitable for ballads that use live instruments.
Earpieces, Cable, Amplifier
These easy-to-use earphones sound great even when plugged directly into a smartphone.
We recommend re-cable and replacing the earpieces.
We use earpieces that emphasize the high frequencies.
The re-cable works well with cables that use high-purity copper wire.
Note that these earphones are compatible with TFZ connectors, so few people may have a compatible cable.
You can also use a 0.78mm 2-pin connector, but please note that the strength of the connection will be reduced and there is a risk of the pins being bent or damaged.
Comparison
We will compare it with a 1DD+1BA hybrid device in the same price range.
Both use a metal faceplate and a resin shell.

KZ ZSN PRO 2
The ZSN PRO2 has a sharp high range, while the BC01 PRO has a strong low range, so there is a big difference between the two models.
The ZSN PRO2 has a clear, crisp sound quality, while the BC01 PRO has a fuller sound.
The ZSN PRO2's sound, which I thought was boomy, doesn't feel so extreme after all.
NICEHCK DB2
The DB2 has a sound quality closer to the BC01 PRO than the ZSN PRO2, but there is a difference in the bass range.
I felt that the DB2 had a well-balanced sound quality.
However, the DB2 cannot reproduce the powerful sound of the BC01 PRO.
Summary
The BC01 PRO are earphones that deliver powerful, impressive sound.
The thick bass range is particularly appealing, allowing you to enjoy EDM and other electronic music even more.
Of course, there are some aspects that are commensurate with the price, but overall the finish exceeds the standards of entry-level models.
They also have excellent fit and sound insulation, making them comfortable even when used for long periods of time.
Considering the price, these earphones are recommended not only for first-time hybrid earphones, but also for anyone who wants to enjoy powerful sound easily.
