Headphones — Stax SR-007MK2

The SR-007MK2 is a legendary electrostatic over-ear headphone from Stax, part of the celebrated flagship-adjacent Omega lineage, built with an extraordinary impedance figure typical of electrostatic driver technology. The SR-007MK2 brings Stax's most storied electrostatic engineering heritage to a serious open-back over-ear format.

Key specs that matter

The transducer uses electrostatic or planar-magnetic driver technology in an open-back, over-ear, wired configuration. Frequency response spans an exceptionally wide 6Hz to 41,000Hz within plus-or-minus 10dB. Sensitivity is 100dB SPL at 1kHz/1mW, with impedance at an extraordinary 170,000 ohms - a figure characteristic of electrostatic driver technology, which operates on fundamentally different electrical principles than conventional dynamic drivers. Weight is 512g.

Sound and use context

Expect the exceptionally fast, detailed character Stax's legendary electrostatic driver technology is broadly celebrated for, with the exceptionally wide 6Hz-41kHz bandwidth representing accomplished current electrostatic engineering.

Pairing

The SR-007MK2 requires a dedicated electrostatic headphone amplifier rather than a conventional headphone output, given the electrostatic driver's fundamentally different operating principles.

Alternatives

Stax's own flagship SR-009S offers a more accomplished current alternative within the same broader electrostatic catalogue.
