The Stax SR-5 is an electrostatic headphone model that was released as part of the Stax series, known for its exceptional audio reproduction capabilities. Designed with a focus on delivering high fidelity, the SR-5 uses electrostatic transducer technology, which allows for a wider frequency response and lower distortion levels compared to traditional dynamic headphones. The construction of the SR-5 features a lightweight design, making it comfortable for extended listening sessions. The headphones require a compatible energizer unit or amplifier to operate, as they do not have built-in amplification. The SR-5 is often appreciated by audiophiles for its clarity, detail retrieval, and spacious soundstage, making it suitable for a variety of musical genres. It has an impedance rating that is typically higher than dynamic headphones, usually around 240 kOhms, thus necessitating specific amplifiers designed for electrostatic headphones to achieve optimal performance. Overall, the Stax SR-5 exemplifies the unique characteristics of electrostatic sound, offering an immersive listening experience.
