The Stax SR-1 is an electrostatic headphone model introduced in the early 1980s, known for its lightweight design and detail-oriented sound reproduction. These headphones utilize an electrostatic transducer, which operates by creating an electric field between two charged plates, allowing for a highly responsive diaphragm. The SR-1 is designed to provide an open and airy soundstage, with a focus on clarity and precision across a wide frequency range. The headphones require an external energizer or amplifier to function, as they operate at higher voltages compared to conventional dynamic headphones. The build quality features a minimalistic aesthetic, combined with a comfortable ear pad design, ensuring long listening sessions are pleasant. The impedance typically measures around 120 kΩ, making it crucial to pair the SR-1 with an appropriate Stax amplifier for optimal performance. Users often praise its performance with classical music and acoustic recordings, highlighting the headphones' ability to convey fine nuances in the audio spectrum.
