QDC x Fitear Superior EX

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 larges  manufacturer of pro-use IEM in Japan. 

By adopting an aluminum 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.

Superior EX Collaboration: The Superior EX is a groundbreaking collaboration between qdc and FitEar, Japan's largest custom IEM manufacturer. This joint effort aims to provide users with an enhanced musical experience by combining the expertise of two respected brands in the IEM industry. The Superior EX focuses on expanding the dynamics of music reproduction, making it suitable for a broader range of music genres and applications.

New 10mm Dynamic Driver: The Superior EX features a newly developed 10mm single full-range dynamic driver. This driver is designed to deliver accurate music playback with a focus on fast transient response and sub-bass reproduction. The driver ensures a balanced sound signature across all frequencies, providing a natural and harmonious listening experience that aligns with the qdc brand identity.

Enhanced Housing Material: To further refine the sound quality, the Superior EX utilizes an upgraded aluminum housing. This change was made to better suppress resonance, resulting in a cleaner and more detailed sound. The aluminum housing works in tandem with the new driver to deliver a superior audio experience that remains stable even at high sound pressure levels.

Silver-Plated OFC Cable: The Superior EX comes with a 4-core silver-plated OFC (oxygen-free copper) cable. This cable is specifically designed to enhance the depth and clarity of sub-bass playback, allowing users to fully experience the rich, dynamic range of their music. The high-quality cable also contributes to the overall sound balance and detail resolution.

Balanced Tuning for Vast Dynamics: Jointly tuned by qdc and FitEar, the Superior EX is engineered to reproduce the vast dynamics inherent in music. The tuning process focused on achieving a balance that allows the IEM to handle increased sound pressure without distorting or collapsing. This ensures that the Superior EX can deliver a consistent and enjoyable listening experience across various music genres, from studio recordings to live performances.
