To visually convey the traits of high-resolution audio with high-fidelity reproduction, we believe that high resolution earphones should be included in commercial-use audio equipment. We have tried to create a “lean form with only the necessary functions exposed”, a common characteristic among recording equipment such as mixers and microphones. We completed the structure of these earphones with an affinity for other business-grade audio equipment by merging the housing and cables instead of having cables hanging down directly from the housings as seen in most existing earphones.
