Sound Quality and Signature

The CCZ Duet BC04 Pro offers a balanced-plus-bright sound signature, placing emphasis on the mids, upper mids, and treble frequencies. The bass response is present but not overpowering.

Vocals are exceptionally clear and detailed, benefiting from the crisp treble response. The overall detail retrieval is excellent, providing a nuanced and enjoyable listening experience.

The soundstage is surprisingly spacious for an IEM in this price range, providing a decent sense of depth and instrument separation.

While not ultra-wide, the soundstage enhances the overall listening experience and provides ample space for all elements in the mix.

Final Verdict

The CCZ Duet BC04 Pro IEMs deliver a fantastic listening experience for their price, excelling in detail retrieval and vocal clarity. The bright sound signature suits those who prioritize crispness and precision.
