STAX Lambda SR-L700MK2

The SR-L700 sound element uses a hand-selected SR-009 thin-film diaphragm and fixed electrodes machined by three-layer stainless steel etching using heat diffusion. A response rich in deep bass, delicate high frequencies, and soothing mids was obtained in a balanced sound. The SR-L700’s arc assembly (ARC) is equipped with a 10-click sliding mechanism for adjusting the height of the headpad adopted from the SR-009. Once adjusted, the slider always maintains its optimal position, making readjustment unnecessary. This allows you to enjoy hours of pleasant music listening with optimal comfort.

Hybrid Cable

99.99999% high-purity copper wires are used for the base wires, and six 99.9999% high-purity silver-plated copper wires are arranged for the perimeter. The entire cable uses the conventional large-format parallel structure to lower the capacity between each wire and terminates in the most appropriate structure for driving the earpiece.
