Below are excerpts from the review:
The M120B delivers surprisingly good sound quality for an all-in-one cable at its price point. It offers a balanced, detailed, and dynamic sound with a low noise floor, creating a clean and clear backdrop for music reproduction. The built-in DAC avoids unwanted coloration or distortion, faithfully preserving the original sound signature of connected IEMs.
Showcasing decent resolution and transparency, the M120B handles complex tracks competently for its price range. It presents a relatively wide and spacious soundstage, fostering a realistic listening experience. The imaging is fairly accurate and precise, effectively pinpointing the position and direction of instruments and vocals.
