The S12 Ultra from Letshuoer represents the most advanced evolution of the S12 in-ear headphones. They feature a 14.8mm planar magnetic driver optimised for more linear and consistent sound reproduction, combined with a new silver-plated copper cable. Their improved ergonomic design and modular connectivity enhance their versatility and comfort, even during long listening sessions.

Letshuoer S12 Ultra: 14.8mm planar magnetic driver

The S12 Ultra uses a 14.8mm planar magnetic transducer. This architecture ensures linear movement, minimal distortion and accurate reproduction across the entire spectrum, and excels particularly in the reproduction of high frequencies. The Ultra version of the S12 benefits from optimised internal geometry to ensure the most faithful audio reproduction possible.

In addition to a high-quality cable, the S12 Ultra features modular connectivity, allowing you to choose between a 3.5mm and 4.4mm jack connector, ensuring compatibility with both single-ended and balanced sources. What's more, a 3.5mm to USB-C adapter is also included, simplifying connection to mobile devices.
