The Trio is an engaging sounding iem with agile yet impactful bass, detailed midrange and smooth treble. There is a controlled and tight presentation. The soundstage has good depth and width which contributes to an open feeling. In addition, the Trio has good build quality. The Mofasest Trio has good implementation of DD, BA & EST and having heard more expensive IEMs that use similar drivers combination, the Trio definitely hit it out of the ballpark with a satisfying listen and without a flagship pricing.
