LETSHUOER – S12 Ultra 14.8mm Planar Magnetic Driver IEM

Discover the LETSHUOER S12 Ultra, the last IEM in the S12 series and a 14.8mm single planar magnetic driver. This custom driver specializes in lightning-fast transients, ultra-high resolution and immersive soundstaging. Its optimized magnetic array and thin diaphragm produce authoritative sub-bass rumble, natural timbre in transparent mids, airy treble extension, and pinpoint imaging with wide staging. Premium CNC-machined aluminum alloy shells deliver solid yet lightweight construction and refined anodized finishing. The ergonomic contours ensure secure and pressure-free fit for all-day wear. Balanced tuning features a tasteful sub-bass lift, neutral-leaning mids, and smoother highs versus prior S12 models, excelling in macro-dynamics, micro-detail retrieval, instrument separation and black backgrounds for holographic presentation. The 392-Core high-purity silver-plated OFC cable minimizes microphonics. The bundle also includes a DT01 USB-C DAC/Amp dongle which provides robust power, low-noise floor and plug-&-play connectivity with mobile phones and PC.
