7Hz Timeless II Planar Magnetic IEM HiFi Earbuds | 7N OCC Cable
7Hz Timeless II — Next-Generation Planar Magnetic In-Ear Monitor
Experience a new benchmark in personal audio with the 7Hz Timeless II. Building on the legendary reputation of the original Timeless, this upgraded IEM features a cutting-edge 14.5mm planar magnetic driver, a premium 7N OCC detachable cable, and a tunable nozzle system — all engineered for audiophiles who demand the very best in wired HiFi sound. Made in Mainland China.
The 7Hz Legacy
7Hz has earned worldwide recognition through beloved models like the Salnotes Zero, Dioko, and the original Timeless — each celebrated for outstanding sound-to-value performance. The Timeless II carries that legacy forward with bold engineering innovations and a commitment to the global audiophile community.
World-First Dual-Sided Coated Diaphragm
The Timeless II introduces the world's first dual-sided coated diaphragm deployed in an IEM platform. 7Hz's proprietary in-house coating process applies a microns-thick, precisely even layer of specialized silver alloy to both sides of the diaphragm. This dramatically increases surface tension, resulting in faster transient response and more accurate sound reproduction across the entire frequency range.
Driven by a powerful dual-sided N52 magnet array, the 14.5mm diaphragm is extraordinarily responsive — delivering the speed, detail, and dynamic range that planar magnetic technology is celebrated for, now refined to a new level of performance.
Tunable Nozzle System
The Timeless II features a tunable nozzle design that lets you fine-tune the sonic signature to match your listening preferences — whether you prefer a neutral reference sound, an elevated bass presence, or enhanced treble clarity. This level of personalization is rare at any price point.
Premium 7N OCC Cable
Included is a high-purity 7N OCC (Ohno Continuous Casting) cable with a standard 0.78mm 2-pin connector, ensuring ultra-low signal loss and clean, transparent audio transmission from your source to your ears.

Frequently Asked Questions
Q: What makes the 7Hz Timeless II different from the original 7Hz Timeless?
A: The Timeless II features an upgraded 14.5mm planar magnetic driver with the world's first dual-sided coated diaphragm, a stronger dual-sided N52 magnet array, and a new tunable nozzle system for sound customization — significant engineering advances over the original model.
Q: What does the tunable nozzle on the Timeless II do?
A: The tunable nozzle allows you to adjust the acoustic output of the earbuds to shift the frequency emphasis — helping you tailor the sound signature toward more bass, more treble, or a balanced neutral profile to suit your personal listening preferences.
Q: What type of cable does the 7Hz Timeless II include, and can it be replaced?
A: The Timeless II ships with a premium 7N OCC (Ohno Continuous Casting) cable connected via a standard 0.78mm 2-pin connector. This is one of the most common IEM connector standards, making it easy to swap in any compatible aftermarket cable for further sound customization.
Q: Is the 7Hz Timeless II easy to drive from a smartphone or portable player?
A: With a relatively low impedance of 15.2 ohms and high sensitivity of 108 dB/V, the Timeless II is more efficient than many planar IEMs. While a dedicated DAC/amplifier will unlock its full potential, it can be driven by quality portable players and high-output dongles.
