About the Brand: The 7Hz Legacy
7Hz has become a global name in high-performance IEMs (in-ear monitors) with iconic models like Salnotes Zero, Dioko, and Timeless. Known for delivering exceptional sound at unbeatable value, 7Hz continues to innovate for audiophiles and professionals alike.
7Hz x Crinacle: The Collaboration That Made History
The original Zero, a collaboration between 7Hz and renowned audio reviewer Crinacle, made history as one of the best-performing budget IEMs on the market. Crinacle, known globally for his influential frequency graph database, has reshaped the audio industry with his insights. Drawing on his extensive experience with IEM and headphone sound profiles, Crinacle once again lent his expertise to tune the Zero for optimal tonal balance. The updated Zero:2 incorporates his refined input, elevating the already successful design to a new level of performance.
More Bass, Keeping Tonal Excellence
The original Zero featured one of the best-in-class tonal balances for a budget single dynamic driver IEM. However, this balanced tuning meant the bass was somewhat restrained, which may have left listeners wanting a more exciting low-end experience. The Zero:2 preserves this ideal sound signature while boosting the low frequencies by 3dB, delivering a more engaging and powerful bass presence that truly brings your music to life. Bass impact and extension are significantly improved, adding more texture and tactile hits to the lows. Additionally, the midrange has gained a slightly fuller body and warmth compared to the original Zero. This subtle warmth in the low-mids enriches the fundamental frequencies of instruments and vocals, while still keeping melodies clean and free from bass bleed.
New 10mm Dynamic Driver
The tonal improvements of the Zero:2 are made possible by a newly developed 10mm dual-cavity dynamic driver. Featuring an upgraded PU+Metal composite diaphragm, this driver is significantly more responsive, enabling faster diaphragm movement. This results in harder-hitting bass while maintaining crispness and precision with every note. Covering a frequency range of 10Hz to 20kHz, the enhancements in the new driver are immediately noticeable.
Improved Custom Cable
7Hz x Crinacle Zero:2 has been upgraded with a new high-purity oxygen-free copper cable plated with silver. The cable features a coaxial structure, with each wire tightly woven using 140.06 and 250.06 windings to enhance durability and improve audio transmission. It is also removable, allowing you to customize your listening experience and extend the lifespan of your IEM.
