The SR-X1 is an electrostatic over-ear headphone from Stax, built with an extraordinary impedance figure characteristic of electrostatic driver technology. The SR-X1 brings Stax's legendary electrostatic driver engineering to a lightweight open-back over-ear format.
Key specs that matter
Frequency response spans an exceptionally wide 7Hz to 41,000Hz within plus-or-minus 10dB, matching the L-series. Impedance is an extraordinary 145,000 ohms, characteristic of electrostatic driver technology. Weight is a remarkably light 234g for the headphone body alone - considerably lighter than the rest of Stax's electrostatic catalogue.
Sound and use context
Expect the exceptionally fast, detailed character Stax's legendary electrostatic driver technology is broadly celebrated for, packed into this remarkably lightweight chassis relative to the brand's broader electrostatic catalogue.
Pairing
The SR-X1 requires a dedicated electrostatic headphone amplifier rather than a conventional headphone output.
Alternatives
Stax's own SR-L300 offers a related model within the same broader accessible electrostatic catalogue.
