Below are excerpts from the review:
The ddHiFi Janus 3 is a Single Dynamic Driver IEM that delivers a balanced sound with a slight emphasis on the lower and upper frequencies. The bass is deep and powerful, the midrange is clear and detailed, and the treble is smooth yet crisp. The soundstage is wide and realistic, creating a sense of space and depth in the sound. This overall sound profile makes the Janus 3 pretty suitable for various genres of music, such as rock, pop, jazz, classical, metal, country and folk.
