STAX SR-007S
Reference Electrostatic Headphone with Exceptional Naturalness
The STAX SR-007S is regarded as one of the most legendary electrostatic headphones ever created and has long represented the extraordinary naturalness, coherence and tonal realism that STAX is famous for worldwide. Compared to the more open and airy Lambda series, the SR-007S delivers a denser, fuller and more organic presentation.
Its specially engineered electrostatic push-pull driver design uses an ultra-light diaphragm capable of reproducing even the smallest details with virtually no delay. The result is an exceptionally lifelike presentation of vocals, instruments and spatial information, delivered with a smoothness and effortlessness rarely found even among ultra high-end headphones.
The SR-007S combines the signature speed and resolution of electrostatic technology with surprisingly deep, weighty and controlled bass performance. Unlike many analytical high-end headphones, the SR-007S never sounds artificial or exaggerated, instead focusing on natural balance and long-term listening comfort.
Its solid aluminum construction, premium materials and ergonomically shaped earpads further contribute to excellent comfort and build quality. Sonically, the SR-007S is especially appealing to listeners seeking maximum realism, natural timbre and a highly immersive presentation.
Like all STAX electrostatic headphones, the SR-007S requires a dedicated electrostatic amplifier or energizer with a PRO bias connection.

Frequency response
What does this mean?
The line marked as target is something you could call the “ideal” curve: a target response derived from research by the Harman group, exploring what kind of headphone tuning tends to be preferred by a broad range of listeners – regardless of age or demographics. This is often referred to as the Harman Target.
From left to right you see sub-bass, bass, mids, and then the curve tilts upward where treble begins. That part of the spectrum is naturally amplified by the shape of the human ear.
Sub-bass sits far below the target – common for open headphones, the Harman target includes a strong bass shelf, the bass is slightly reduced. The lower mids are neutral, the presence region around 3 kHz sits clearly below the target. The treble is strongly tuned more relaxed – never sharp, easy over long sessions, and the range above 10 kHz stays on the curve. Left and right channels track each other closely, a sign of careful driver matching.
