7Hz Timeless II Upgraded 14.5mm Planar Magnetic Driver IEM

The 7Hz Legacy

7Hz made a global wave in the past with several of its most popular models. IEMs such as the Salnotes Zero, Dioko, and Timeless gathered massive popularity due to their amazing sound-to-value performance. 7Hz has proven itself to the worldwide audience as a trusted manufacturer of high-performance IEMs, and will continue its legacy with better innovations and stronger community engagement. 

Upgraded 14.5mm Planar Magnetic Driver: Building on the success of the original Timeless, the Timeless II introduces an upgraded 14.5mm planar diaphragm—the first dual-sided coated diaphragm in an IEM. Using a specialized silver alloy coating and driven by a powerful dual-sided N52 magnet array, this new diaphragm delivers exceptional responsiveness, pushing planar technology to new heights. 

Tunable Nozzle Design: The Timeless II features a tunable nozzle system, inspired by speaker phase plugs, allowing users to adjust ultra-high frequencies to their preference. Different nozzle options provided to offer precise sound adjustments to suit any music library.

Redesigned Driver Enclosure: The new planar drivers are housed in a 7-layer acoustic enclosure with double rear venting and a secure locking system, ensuring balanced, natural tuning. The diaphragm is directly mounted for increased rigidity, stability, and tighter surface tension.

Upgraded Detachable Cable: Equipped with a 4-core ultra-pure 7N single-crystal copper cable and 0.78mm 2-pin connectors, the Timeless II offers enhanced warmth, body, and detail. The detachable cable design allows for easy customization and extended durability.
