The 7Hz Timeless II upgrades the original with a 14.5mm planar magnetic driver, featuring the world’s first dual-sided coated diaphragm for enhanced responsiveness. It also introduces a tunable nozzle system, allowing users to adjust sound with different nozzle options. The redesigned 7-layer driver enclosure ensures precise tuning, durability, and stability.
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.
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
The original Timeless was one of the benchmark planar driver IEMs when the concept was first started. Since then, we have had much time to re-examine the planar magnetic driver, and innovate more efficient designs. The Timeless II features the latest R&D from our team, with a bigger 14.5mm diaphragm. This new 14.5mm planar diaphragm is the world’s first dual-sided coated diaphragm to be used in the IEM platform. Our in-house coating process layers microns-thick even surface application of specialized silver alloy, which significantly increases the surface tension of the diaphragm. The new diaphragm, which is driven by a strong dual-sided N52 magnet array, is extremely responsive, taking the planar diaphragm concept to a whole new level.

Tunable Nozzle
The Timeless II also features a new tunable nozzle concept, so that the user can adjust their sound preference. This idea is derived from the concept of speaker phase plugs, which allows the extension and adjustment of ultra-high frequencies. We have designed special nozzle shapes, with different materials for precise tuning of the IEM. The different nozzles all provide unique and effective ways to adjust the Timeless II's sound to fit your music library.

Newly Designed Driver Enclosure
The Timeless II’s new planar drivers required a redesign of the acoustic driver enclosure to provide a balanced and natural tuning. With a 7-layer design featuring a double acoustic rear venting system and a more secure locking system, the driver can be more precisely tuned, as well as be more durable and stable. The diaphragm was also directly mounted onto its support structures to provide more rigidity and tighter surface tension within the driver.

Updated Cable
The Timeless II comes standard with our new upgraded cable. The cable is a 4-core ultra pure 7N single-crystal copper cable, with detachable 0.78mm 2-pin connectors. This configuration was specifically chosen to provide additional body and warmth to the Timeless II’s new driver, while enhancing the transparency and details. With the detachable cable design, the user can change the cable to fit their preference, as well as extend the longevity of their IEM.
