Four-Driver Hybrid Setup
The media channel that is Gizaudio has combined with Binary Acoustics to tune the Chopin. This IEM houses a four-driver hybrid configuration featuring a low-frequency dynamic driver, midrange customized BA, and high-frequency customized composite dual BA driver setup on each side.
It has been crafted using top-quality components along with simulated tuning adjustments by Gizaudio. Binary Acoustics has designed the Chopin with a four-driver hybrid configuration. Using an 8mm ceramic diaphragm dynamic driver unit that complements the other frequencies with a strong bass presence. There is a one customized BA driver unit for delivering quality sound in the midrange section, and a composite dual-BA driver customised unit for clear and accurate high-frequency response. Its sells for $200 USD.
Sources and listening
I used the excellent supplied oxygen free silver cable and my favoured TRT T tips which allow deep insertion, with my Hiby R3 Saber 2022 DAP and lossless audio files. The Chopin has a wide nozzle to accommodate three audio channel outlets and I found some larger tips caused a bit of discomfort with my ears. Individuals are recommended to experiment with tips to find the right depth and fit for their ear canals. My initial listing impressions were formed with this music source, but I later found there was a very good synergy between the IEM and the Hidizs S9 pro Martha DAC that has just been released. The S9 pro enhanced the high frequencies and gave the bass more weight while retaining excellent clarity and energy. This became my favoured combination.
Sound Breakdown
The Chopin is easy to drive but does thrive on a more powerful DAC. The sub bass and lower bass register dominate with a warm deep and well controlled response. It goes deep with great control and good speed. Bass guitars have good texture and snare drives good bite and punch. It’s a very enjoyable bass if you are that way inclined. The mid bass is fast and detailed but a little lacking in quantity. Having said that it allows the midrange room to move and breathe. I would say the Chopin’s portrayal of the bass frequencies will scale very nicely with a more powerful source.
The midrange is very natural in timbre and the vocals placed well, slightly forward with good air and space around them. Bass frequencies do not intrude. The placement of instruments around the vocals is pinpoint. The midrange is well balanced and neutral. The soundstage is average left to right with good height and depth. Instrument positioning is precise and its easy to locate the players. The imaging allows a spacious headspace and draws you into the musical performance.
The treble is smooth, airy, and non-fatiguing, facilitating very good detail retrieval, if not class leading.
Conclusion
With the right source and eartips the Gizaudio and Binary Acoustics Chopin is a competent and energetic IEM. Well recorded albums from Supertramp, Tom Petty and Fleetwood Mac really shine with the Chopin showcasing its great resolution and balanced clean acoustic soundstage. Chopin handles every genre I threw at it with aplomb, from DEM to rock to indie and Taylor Swift! It’s a very enjoyable listen and recommended.
yeah youre going to LOVE this.
