Know before you buy
Yes. Because these are electrostatic headphones, they require a dedicated STAX-compatible electrostatic driver unit (energizer) to provide the necessary 580V DC bias voltage. They cannot be driven by standard headphone jacks or traditional amplifiers.
The SR-007S offers a more transparent and nuanced sound profile characterized by extreme speed and detail. Electrostatic technology allows for a much thinner diaphragm, resulting in superior transient response and a highly accurate, expansive soundstage that feels less colored than traditional dynamic drivers.
The SR-007S is designed for extended use, featuring an improved hinge mechanism for a better fit and premium sheepskin ear pads that provide excellent comfort and sound isolation. At 430 grams, they are substantial but balanced to minimize pressure during long sessions.
The ARS utilizes a seamless stainless steel plate to increase the rigidity of the headphone housing. By reducing unwanted vibrations and resonance, it ensures that the sound remains clean and precise, even during complex musical passages.
Yes, the SR-007S features a detachable cable design. This makes maintenance straightforward and allows you to replace the cable easily if it wears out over time.
These headphones excel with acoustic, classical, and jazz recordings where detail, tonal accuracy, and instrument separation are paramount. Their ability to resolve fine textures makes them a favorite for listeners who prioritize high-fidelity reproduction of complex arrangements.
