LETSHUOER S08 IEM 13mm Planar Magnetic Driver in Ear Monitor HiFi Earphone

Look Alive, Sound Alive

Fourth Generation Dual Voice Coil custom 13mm Planar Magnetic Driver 

• LETSHUOER S08 Hifi planar IEM features a custom fourth generation 13mm planar diaphragm speaker that LETSHUOER was very hands-on during the development process.
• LETSHUOER utilizes nanoscopic magnetron sputtering process,a high-end production method, on the planar driver’s diaphragm of S08,sputters the copper material onto the substrate.
• The nanoscopic magnetron sputtering technology coats the diaphragm with a layer of voice coil in addition to conventional drivers’ single layer voice coil circuit.
• They incorporated a PTR elastic film surrounds at the edge of the diaphragm’s voice coil, which makes the diaphragm perform with greater extensibility and stability.
• The LETSHUOER S08 incorporates the design language of the number "8" in its panel design, featuring a striking yet streamlined appearance.
• The CNC precision-milled metallic earphone shell is both simple and exquisite. It is available in black and silver versions to meet different aesthetic preferences.
• The cables are made from 4 cores of 30-strands 0.05mm silver-plated copper, providing efficient transmission performance, finer musical detail, and a richer sense of space.

Nanoscopic magnetron sputtering process

LETSHUOER Planar earphones utilizes nanoscopic magnetron sputtering process, a high-end production technology, on the planar driver of S08, sputters the copper material onto the substrate.

This process yields high stability and long lifespan. In terms of sound performance, it enhances the resolution of high frequencies, which elevates the texture of high frequencies to the next level.

Dual Voice Coil Planar Diaphragm

The nanoscopic magnetron sputtering technology coats the diaphragm with a layer of voice coil in addition to conventional drivers’ single layer voice coil circuit.

This makes the S08’s HiFi earbud driver diaphragm a dual-layer coil circuit. Benefits include increasing diaphragm vibration control, reducing resonance frequency, minimizing distortion caused by diaphragm resonance, and effectively enhancing overall transient response speed.

Driver diaphragm with surrounds

LETSHUOER took matter into our own hands during the customization process of S08 driver unit.

They incorporated a PTR elastic film surrounds at the edge of the diaphragm’s voice coil, which makes the diaphragm perform with greater extensibility and stability.

This effectively optimizes the low-frequency performance, significantly enhancing the depth of the bass and providing a much tighter bass presentation.

High Quality Modular Cable

An excellent cable was chosen to bring the most out of the earphone units, so to not bottleneck the transducers.

 The cables are made from 4 cores of 30-strands 0.05mm silver-plated copper, providing efficient transmission performance, finer musical detail, and a richer sense of space. It is also equipped with modular 3.5mm and 4.4mm plugs. 

The twist-lock design ensures the durability and reliability of the plugs.

This makes adapting to most source devices a very simple task.
