STAX SRL-700

Headphones from the new Advanced-Lambda range The first SR-Λ (Lambda) range was launched 36 years ago, then it was modified to lead to a new generation SR-Λ (Lambda), whose design of the sound element support has been revised: the new range of SR-L700 Advanced-Lambda headphones.

A superior quality sound element: As with the SR-009 model, the SR-L700 uses a custom thin-film diaphragm, as well as fixed electrodes machined by a three-layer tin-free heat diffusion etching process. This allows for a beautifully balanced tonal sound with an extended response in the range.

An adjustable ratchet headband: The SR-L700’s headband features a ten-position ratcheting slide mechanism for adjusting the ear pads. Once adjusted, the sliding device will retain this optimal position without further adjustment, ensuring optimal listening pleasure and comfort, even over the long term.

A new low-capacity HiFC cable: High-purity 6N-grade copper strands were used for the central conductors, combined with six silver-plated braided conductors arranged around the periphery. The cord has the usual flat parallel structure along its entire length, which reduces the capacity between each of the cord’s conductors. And further increases the felt impression of “sound purity”.

A new genuine leather ear pad structure: The new structure and breathability of the genuine lambskin leather ear pads not only contribute to the soft feel, thanks to their flexible adaptation to the head, but also to the “purity” and “grace of the sound signature” delivered by the SR-L700.
