Experience the pinnacle of budget audio engineering with the 7Hz x Crinacle Zero:2, a collaboration between 7Hz and world-renowned audio reviewer Crinacle. This refined IEM builds upon its legendary predecessor with a newly engineered 10mm dynamic driver featuring a PU+Metal composite diaphragm for enhanced responsiveness and precision. The Zero:2 elevates the original's acclaimed tonal balance by introducing 3dB additional bass presence, delivering powerful low-end impact while preserving midrange warmth and clarity. Paired with an upgraded oxygen-free copper cable with silver plating in a coaxial structure, the Zero:2 offers removable connectivity for customization. With 32Ω impedance, 108dB sensitivity, and 10Hz-20kHz frequency response, these wired earphones provide studio-grade performance for discerning listeners, musicians, and audiophiles seeking exceptional value without sonic compromise.
