The STAX SR-L300 electrostatic headset costs less than 3,000 yuan

When it comes to electrostatic headphones, I think of STAX. The past static headphones are not cheap, but STAX has launched a model SR-L300 that sells for only 40,000 yen. It is only about 2280 yuan, and it is still worn.
However, since the static earphones require special power supply, the audio plugs are specially made, and a special amp is required. The SR-L300 with a dedicated amp SRM-252S package SRS-3100 costs a total of 67,500 yen, equivalent The RMB is about 3,860 yuan.
SR-L300 has a frequency response range of 7Hz-41kHz, electrostatic capacitance of 110pF, impedance of 145kΩ, and sensitivity of 101db. The earphones can be adjusted for different head sizes, using artificial leather material, and the cable part is made of high-purity OFC material. The whole earphone Weighing 322g.
Electrostatic earphones use the electrostatic field to drive the vibration of the diaphragm. Without the mechanical structure of the past, higher response speed and transient and detailed performance can be achieved. A complete set of electrostatic earphone sets can be purchased for nearly 4,000 yuan. This is quite equivalent. It's cheap.
