The 10mm size provides ample surface area for accurate sound reproduction across the frequency spectrum. The diaphragm is designed with a thin film material through a solution membrane process. It exhibits high melt viscosity and almost Newtonian fluidity. It has identical mechanical properties in both longitudinal and transverse directions, which minimizes the distortion in your music. The 7Hz delivers an impedance of 32Ω, ensuring accurate sound reproduction while maintaining total harmonic distortion (THD) below 0.2% at 1kHz.



The 7Hz has featured the labyrinth cavity structure in the i88 which includes a carefully engineered pipe area to match the section of the horn diaphragm to enhance overall audio performance. The length of the pipe is at 3/4 of the promoted low-frequency wavelength, effectively reducing resonance issues. This design approach amplifies sound output in the vicinity of and below the resonant frequency, resulting in enhanced lower frequencies and adequate energy in the audio output. This labyrinth cavity design structure of the 7Hz i88 is featured to deliver better with better frequency performance. It provides a frequency range of 10-20kHz in your audio.



Similar to the i99 model, the 7Hz i88 prioritizes exceptional sound quality and showcases its distinctive aesthetic appeal in the high-fidelity IEMs category.
