Studio & stage equipment / accessories   |   HEADSETS by "STAX" STAX - "EAR SPEAKER" - the electrostatic headset SOMMER CABLE is proud to present the world's best headsets, from the Japanese company STAX. They are unbeatable when it comes to neutral sound, impulse rendition, high resolution, and low distortion. Since STAX introduced the SR-1 as the first capacitor headset worldwide in 1960, their headsets then became a standard for reference monitoring. An extremely 1.35 µm thin high polymer membrane, biased with 580 V, moves between two perforated metal electrodes, onto which the amplified musical signal is applied. A power supply is required for just that reason. STAX headsets: SRM-001 MK2 SRS-3020 SRS-4040 SRS-007 / SRS-717
