SUPERIOR EX is based on the SUPERIOR concept model of the qdc, China's largest manufacturer of pro-use IEM, and has been jointly tuned with FitEar, the largest manufacturer of pro-use IEM in Japan. This is a large custom IEM brand collaboration model. We focused on reproducing the dynamics inherent in music, and pursued tuning and total balance according to that concept. By adopting an aluminium enclosure and the original silver-plated OFC cable, we have achieved deeper sub-bass playback and enhanced sound details while maintaining excellent transients. With the three meanings of EXECUTIVE, EXTRA and EXPERIENCE, the EX upgrades your music EXPERIENCE to the next level.


Outline of SUPERIOR EX

Superior, the second entry in the qdc concept model series, will allow more people to experience the fitting, sound response speed and sub-bass playback unique to the custom IEM brand for professional use. SUPERIOR EX is an extra concept model that focuses on reproducing the vast dynamics of music and matching it to a wider range of music in order to provide a music experience that takes the user one step further. With the cooperation of FitEar, the largest custom IEM manufacturer in Japan, which sympathised with the concept of the project, we planned and developed the project jointly.

SUPERIOR EX is equipped with a newly developed 10mm single full-range dynamic driver, with the aim of providing more users with the brand identity of comfortable wearing and accurate music playback. Based on SUPERIOR, we updated it while considering the total balance of tuning, housing material, and cable according to the concept. In order to enhance the sound details, the aluminium housing has been changed to further suppress resonance. In addition, the original silver-plated OFC conductor cable with 4 core wire is adopted so that you can feel the deep sub-base playback more. Then, by joint tuning with FitEar, the peak part is suppressed and optimised.

In order to make it possible to reproduce the dynamics of music, we have finished the sound that does not collapse even if the reproduction sound pressure is increased.

Make your music, Superior EX- As the first collaboration in the history of the two major custom IEM brands that respect each other, we will provide users with the three meanings of "EX" : EXECUTIVE, EXTRA, and EXPERIENCE to enjoy music and monitor. It further upgrades the musical experience available in a wide range of applications, from rings to live stages to games.


FitEar joint tuning for the purpose of reproducing the vast dynamics of music

SUPERIOR EX is a tuning based on the SUPERIOR of the newly developed entry IEM concept with the aim of allowing more users to experience the brand identity of comfortable wearing and accurate music playback. We updated each of the housing material, and the cable according to the concept while considering the total balance. Equipped with 10mm single full-range dynamic driver, accurate music playback focusing on excessive characteristics (transients), SUPERIOR for natural and harmonious sound reproduction across a wide range of frequencies and all bands while maintaining the characteristics described above, the areas where peaks occur are suppressed so that they do not collapse even if the sound pressure is increased. We focused on reproducing the vast dynamics inherent in music and jointly tuned it with FitEar for the purpose of matching it to a wider range of music.
