Below are excerpts from the review: “At the end of the day, ddHiFi Surface is all about music, smoothness, fluidity and no harshness, no grain, and no abrasive parts, it has enough resolution and can reveal details well enough to be considered a high-end model, but it is the farthest thing from an analytical sounding IEM as it can be, so I would totally recommend the Surface if you wanted to experience bass and vocals, with zero fatigue and with a recessed, rolled-off and smooth treble.” From：Audiophile Heaven Click here to view more

Below are excerpts from the review: “I enjoyed ddHiFi’s new Surface, particularly its mid-range and instrument timbre. The package comes with plenty of accessories, and all the materials used are of excellent quality. The build quality is also impressive. It is also compact and fits comfortably. The ddHiFi Surface is a hybrid IEM that offers a smooth and musical sound with warm mid-centric tuning. It has a strong sub-bass presence, a lush midrange, and a relaxed treble. It is not a perfectly neutral IEM, but rather one that emphasizes vocal emotion and enjoyment over accuracy and detail.” From：audioAI Click here…
