This is the first collaboration model in history between two major custom IEM brands, completed through joint tuning. SUPERIOR, the second entry in the qdc concept model, focuses on allowing as many people as possible to experience the fitting, sound response speed, and sub-bass playback that are unique to a professional custom IEM brand. By providing EXECUTIVE, EXTRA, and EXPERIENCE to users, we will further upgrade the music experience that can be obtained in a wide range of applications ranging from music listening, monitoring, live stages, and games. ■ [FitEar joint tuning aimed at reproducing the vast dynamics of music] A newly developed concept that allows more users to experience the brand identity of comfortable wearability and accurate music playback. Based on the entry IEM SUPERIOR, we updated the tuning, housing material, and cable while considering the total balance to match the concept. Equipped with a 10mm diameter single full-range dynamic driver, SUPERIOR's excellent features remain, including accurate music playback with an emphasis on transient characteristics, a wide playback range, and natural and harmonious sound across the entire range. In addition, the areas where peaks occur are suppressed so that they are less likely to collapse even when the playback sound pressure is increased. We focused on reproducing the vast dynamics inherent in music, and performed joint tuning with FitEar to match it to a wider range of songs. ■ [Using aluminum as the housing material to enhance sound detail] When considering the total balance of SUPERIOR EX's sound, we considered changing the housing material to make better use of tuning. After conducting multiple tests from a variety of materials, we selected aluminum whose characteristics matched the concept of SUPERIOR EX. By using an aluminum housing for the earphone shell and faceplate, we succeeded in suppressing resonance, enhancing fine sound details, and producing just the right amount of bass. In addition, while using an aluminum casing, it achieves the lightweight and comfortable fitting that is unique to QDC, a custom IEM brand. ■ [SUPERIOR EX Cable that uses a 4-core silver-plated OFC conductor cable] Considering the total balance of SUPERIOR EX's sound, we also changed the attached cable. After testing multiple cables, we selected the original silver-plated OFC conductor 4-core cable so that users can experience a greater dynamic range and deeper sub-bass reproduction according to their tuning and product concept. Covered with a black PVC coating, the SUPERIOR EX Cable is smooth to the touch and easy to handle. The plug uses a stylish 3.5mm 3-pole unbalanced straight plug with a metal sleeve. The connector uses a custom IEM 2pin connector (0.78mm). ●Shape: IEM type (ear hook type)●Driver: Dynamic type (10mm diameter single full range)●Number of drivers: 1DD / 1 driver (one side)●Impedance: 16Ω●Sensitivity: 100dB●Frequency characteristics: 10 to 40,000Hz● Cable length: approx. 1.2m Cable material: Silver-plated OFC conductor 4-core cable Connector: Custom IEM 2pin (0.78mm) Plug: 3.5mm 3-pole Straight plug with metal sleeve ●Accessories: qdcTips Soft-fit silicone earpiece (S/M/L), double flange silicone earpiece (S/M/L), cleaning tool, original carrying case ●Country of production: China ●Manufacturer's warranty: 1 year for main unit / 6 months for cables and accessories
