This is a dongle DAC with a slightly larger size. I feel that the sound quality is as powerful as it looks.

The sound pressure and density increase dramatically, making the sound very deep. The earphones I used were “VE4.2”, which were originally dark earphones, but I felt that the density had increased even more. From what I’ve read so far, I think it sounds persistent, but I didn’t find it to be persistent because of the elegant way it sounded.
