Product Detail
Back to the essence — hear the purity of sound
The DM7S137 is the first high-impedance model in the DM series, tuned warm, rich and natural. A 15.4mm patented diamond-cut suspension-edge polymer diaphragm meets a 137Ω aluminum voice coil with Kaisheng’s patented multi-layer coil technology, delivering an open soundstage, precise imaging and solid presence. The modular wire system supports both 3.5mm single-ended and 4.4mm balanced output.
