LETSHUOER S15 adds a 6mm passive filtering module besides the planar driver. The passive filtering module is LETSHUOER's in-house R-Sonic Dynamic Harmonic Technology. Positive filtering of sound energy through proprietary filters. Suppresses excessive low frequencies, balances air pressure, and provides effective passive resonance. Enhance the overall quality of low frequency, significantly improve the finesse of the sound.
To ensure smooth transitions between the octaves, LETSHUOER S15 employs a dual acoustic tubes structure with filter crossover scheme. Reasonable distribution of energy between the planar driver and the passive radiator reduces the distortion of the music, resulting in high level of clarity and smoothness across the spectrum and rich sound layering.
In collaboration with HeyGear, LETSHUOER S15 shell has been ergonomically polished to fit most people's ear shapes, providing both stability and comfort. The internal structure of the shell has been precisely optimized, contributing to the precise acoustic configuration and extremely low distortion. The faceplate is made of aluminum-magnesium alloy, which went through CNC carving, sandblasting and anodization processes.
To ensure stable sound transmission, LETSHUOER S15 comes with a high-quality 216-strands silver-plated monocrystalline copper cable. S15 adopts standard flush-mounted 0.78mm dual-pin receptacle. Detachable 2.5mm, 3.5mm, 4.4mm 90-degree angle connectors come standard with the unit.
