Headphones — Stax SR-L500MK2

The SR-L500MK2 is an electrostatic over-ear headphone from Stax, sitting above the SR-L300 within the L-series with an extraordinary impedance figure. The SR-L500MK2 brings Stax's more accomplished current electrostatic engineering to an accessible 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 SR-L300. Maximum sound pressure level is a substantial 118dB SPL at 1kHz at 5% THD. Sensitivity is notably high at 101dB SPL at 1kHz/1mW, matching the SR-L300. Impedance is an extraordinary 145,000 ohms, characteristic of electrostatic driver technology. Weight is 471g - somewhat heavier than the SR-L300.

Sound and use context

Expect the exceptionally fast, detailed character Stax's legendary electrostatic driver technology is broadly celebrated for, with the substantial 118dB maximum SPL representing a step up from the SR-L300 within the accessible L-series lineup.

Pairing

The SR-L500MK2 requires a dedicated electrostatic headphone amplifier rather than a conventional headphone output.

Alternatives

Stax's own SR-L300 offers a more accessible, lighter alternative within the same broader L-series catalogue.
