STAX SR-407

These audiophile headphones use electrostatic panel technology and require a compatible amplifier. Thanks to the large emissive surface, the listener is immersed in a musical ambiance that is incomparable to the transducers of traditional headphones. The main characteristic of the listening experience is absolute transparency across the entire audio spectrum, as well as an absence of lag in the bass. In a word, the listening experience is breathtaking.

The Stax SR-307 (gray) and SR-407 (brown) cannot be connected to just any headphone output and require the use of a specific amplifier, particularly due to the constraints related to their impedance. These models are compatible with Stax amplifiers.

Note that the SR-407 version is a color variation and has the same characteristics, with the exception of some variations concerning the inductance and impedance of the modulation cable. The listening experience therefore differs somewhat and proves to be even more spatial.
