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.

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.

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.

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.
Simply amazing bass precision and detail. A bit harsh at 6to10khz but nothing crazy , still well balanced sound, very usable on live sound environments and for listening music. I work as a FOH engineer and needed something to carry around with and listen to details when needed. Very very good overall

just getting into iems, this is significantly better than my airpod pro 3s, you hear so much for such a comparatively low price
Like really good, especially for the money
The clear and detailed sound is incredible. Out of the box without eq they sound amazing. Considering the price it's mind boggling.
